0:00The Big Secret
Right now, at this very second, there is a planet out there in space that no human being has ever seen. Not one person. Not ever. And here is the mind-blowing part: there are probably billions of them, hiding in the dark, waiting to be discovered. Well, guess what? On August 30, a rocket is going to roar off a launch pad carrying the most incredible planet-hunting machine ever built. It is a giant space camera, and its mission sounds like something from a movie: find one hundred thousand brand-new worlds. That is not a typo. One hundred thousand planets that will get names, get studied, and get added to the map of our galaxy for the very first time. Some might be covered in oceans. Some might rain rocks. And some might be a little bit like home. You are about to meet this amazing telescope and learn exactly how it finds invisible planets. But first, you need to see just how enormous this space camera really is.
0:54Meet Roman
Meet the Nancy Grace Roman Space Telescope. Scientists just call it Roman for short, and it is basically a school-bus-sized robot photographer heading to space. Picture this: it is about as long as a giraffe is tall, it weighs as much as a big delivery truck, and it is wrapped in special blankets to keep it cozy in freezing space. At its heart sits a huge, super-shiny mirror almost two and a half meters wide. That is wider than your bed is long! The mirror's job is to catch starlight, the same way a bucket catches rain. The bigger the bucket, the more rain you catch. The bigger the mirror, the more starlight you catch, and the more faint, faraway things you can see. Roman took thousands of engineers many years to build, piece by careful piece, like the world's most expensive puzzle. But the telescope itself is only half the story. Wait until you hear about the brilliant scientist it is named after, because she changed space history forever.
1:50The Mother of Hubble
The telescope is named after a real superhero of science: Nancy Grace Roman. When Nancy was a kid, she started her own astronomy club and stayed up late memorizing constellations with her friends. But here is the tough part. When she grew up, lots of people told her that girls should not become scientists. Can you believe that? Nancy did not listen. She studied hard, became an astronomer, and got a very big idea: what if we put a telescope in space, above the clouds and the wiggly air, where the view is perfectly clear? People said it was too hard and too expensive. Nancy kept pushing for decades. Her big idea became the Hubble Space Telescope, one of the most famous machines ever built, and that is why scientists call her the Mother of Hubble. Now a brand-new telescope carries her name to the stars. Pretty amazing for a kid with a stargazing club, right? And here is the twist: her new telescope can do something Hubble never could.
2:46One Hundred Times Wider
So what makes Roman so special? One word: WIDE. Imagine you are looking at a giant wall covered in stickers, but you have to look through a drinking straw. You can see one sticker at a time, super clearly, but checking the whole wall would take forever. That straw is kind of like Hubble. It takes gorgeous, detailed pictures, but only of a tiny patch of sky at once. Roman is like taking the straw away and opening both eyes. Each single photo from Roman captures one hundred times more sky than Hubble can. One hundred times! In one snapshot, Roman can photograph an area of sky bigger than the full Moon looks from your backyard. That means instead of studying stars one by one, Roman watches millions of stars at the same time, every day, like a security camera for the entire galaxy. And when you can watch millions of stars at once, you start noticing something very strange. Some of those stars... blink. And that blink is a clue.
3:40What Is an Exoplanet
Before we chase blinking stars, let's get one word straight: exoplanet. It sounds fancy, but it just means a planet that orbits a star other than our Sun. Your home team, the solar system, has eight planets circling one star. But look up at night. Every single star you see is a sun, many with their own planet families we know almost nothing about. Here is a wow-fact to tell someone at dinner: scientists now think there are MORE planets in our galaxy than stars. Since our galaxy has around one hundred billion stars, that is a truly ridiculous number of worlds. So far, humans have confirmed almost six thousand exoplanets. That sounds like a lot until you remember there could be billions still hiding out there. It is like we have explored one grain of sand on an entire beach. Roman is about to scoop up a whole bucketful. But hold on. If these planets are real, why can't we just point a telescope and look at them?
4:33The Impossible Problem
Here is the problem, and it is a big one. Planets do not glow like stars. They are dark, and they hide right next to something outrageously bright. Trying to see a planet next to its star is like trying to spot a tiny firefly sitting on a giant lighthouse lamp... from thousands of kilometers away. The star's light is so blinding that the little planet completely disappears in the glare. To make it worse, these stars are unbelievably far away. The nearest star beyond our Sun is so distant that the fastest spacecraft ever built would need thousands of years to get there. So we cannot fly over for a visit, and we cannot see the planets directly. Sounds impossible, right? Well, astronomers are champions at solving impossible puzzles. They figured out sneaky detective tricks to find planets without ever seeing them. Roman is packed with these tricks, and the first one is my favorite. It all starts with catching a star in the middle of a wink.
5:27Winking Stars
Trick number one is called the transit method, and you can understand it with a lamp. Imagine your friend stands across the room holding a bright flashlight pointed at you. Now a tiny bug flies right in front of the flashlight. What happens? For a split second, the light gets just a teeny bit dimmer. You might not even notice unless you were watching super carefully. That is exactly what Roman watches for. When a planet passes in front of its star, the star's light dims a tiny, tiny bit, like a mini eclipse, and then brightens again. The star winks! By timing the winks, scientists can figure out how big the planet is and how fast it zooms around its star. Here is the wow part: the dimming can be less than one percent, and Roman can still catch it while watching millions of stars at once. It is like noticing one person blink in a stadium full of a hundred thousand people. But Roman has an even sneakier trick, and this one uses gravity itself as a magnifying glass.
6:24Gravity's Magnifying Glass
Ready for the weirdest science trick you will hear all week? It is called microlensing, and it sounds like magic. A long time ago, a scientist named Albert Einstein figured out that heavy things in space actually bend light, the way a glass lens bends light in a magnifying glass. So picture this: Roman is watching a faraway star. Suddenly, another star drifts across, right in between. The closer star's gravity bends the faraway star's light and focuses it, making the faraway star flash brighter for a few days, like someone slowly turning a dimmer switch up and back down. Now here is the genius part. If that closer star has a planet, the planet's gravity adds its own tiny extra blip of brightness to the flash. Scientists see the blip and shout: PLANET! The universe basically builds a temporary magnifying glass out of pure gravity, and Roman reads the clues. Einstein predicted this over one hundred years ago. And this trick can find something truly wild: planets that have no star at all.
7:24One Hundred Thousand Worlds
Add up all of Roman's tricks and you get that jaw-dropping number: scientists expect it to discover around one hundred thousand new planets. Let's feel how big that is. Every planet humans have found so far took us more than thirty years of searching. Roman could multiply that by more than ten. If you tried to say the name of every planet Roman finds, one per second, without stopping to eat or sleep, it would take you more than an entire day of nonstop talking. Imagine the map of our galaxy before Roman: mostly blank, with a few dots. After Roman: dots everywhere, like someone spilled glitter across the map. Every dot is a whole world with its own sky, its own weather, its own mysteries. Some will be gas giants bigger than Jupiter. Some will be small rocky worlds. Each one gets a name in a catalog and becomes a place future scientists, maybe you, can study. But some of the planets Roman finds will be extra spooky-cool, because they are wandering through space totally alone.
8:23Lonely Wandering Planets
Most planets circle a star, like Earth circles the Sun. But some planets are drifters. Scientists call them rogue planets, and they zoom through the darkness of space with no star, no sunrise, no sunset. Forever night. How does that happen? When planet families are young, the planets sometimes play a giant game of gravity bumper cars. A big planet's gravity can fling a smaller planet completely out of its solar system, like a slingshot. Off it goes, alone into the dark. Here is the wow-fact: scientists think there could be BILLIONS of rogue planets in our galaxy, maybe even more rogues than stars. But because they make no light and have no star to wink, they are almost impossible to find. Almost. Remember microlensing, the gravity magnifying glass? A rogue planet drifting past a faraway star bends its light just enough for Roman to catch it. Roman may find hundreds of these lonely wanderers. Now, to do all this amazing spotting, Roman needs the perfect parking spot in space. And wow, did scientists pick a good one.
9:25The Perfect Parking Spot
You cannot just plop a telescope anywhere in space. Roman is headed to a special spot called L2, and it is about one and a half million kilometers from Earth. That is roughly four times farther away than the Moon! Why so far? Three reasons. First, at L2, the Sun and the Earth are both behind the telescope, so Roman can face the cold, dark deep sky without bright stuff photobombing its pictures. Second, L2 is a gravity sweet spot. The pull of the Sun and the Earth team up perfectly there, so Roman can glide along with Earth around the Sun like a skater holding onto a friend, barely using any fuel. Third, it is nice and cold out there, and telescope cameras LOVE the cold. Heat makes their pictures fuzzy, like fog on a bathroom mirror. Fun fact: Roman will have famous neighbors, because the James Webb Space Telescope hangs out near L2 too. But before Roman can move into its new home, it has to survive the wildest ride of its life: launch day.
10:24Blast Off Day
August 30. Launch day. Picture the scene: a massive rocket stands on the pad, taller than a fifteen-story building, hissing and steaming in the morning air. Tucked safely inside the nose cone, wrapped up like the world's most precious present, sits Roman. The countdown begins. Ten... nine... eight... Engineers in the control room hold their breath. Three... two... one... IGNITION! The engines light up with a rumble so powerful you can feel it in your chest from kilometers away. Flames and steam billow everywhere, and slowly, then faster and faster, the rocket climbs into the sky riding a tower of fire. In about eight minutes, it is going many times faster than a speeding bullet. Wow-fact: during launch, the rocket shakes and roars with more power than a hundred thousand race cars. Roman was built tough to survive every rattle. High above Earth, the nose cone pops open like a flower, and Roman floats free into space at last. But the scariest part is not over. Now Roman has to wake up... all by itself.
11:23Waking Up in Space
Alone in the darkness, far from home, Roman begins to stretch. Its solar panels unfold like wings and drink in sunlight for power. Its antenna swivels toward Earth and calls home: signal received! In the control room, everyone cheers and hugs. But nobody relaxes yet, because for weeks, Roman must pass a checkup on every single part while it slowly cruises out to L2. Cameras on. Heaters on. Mirrors aligned so precisely that if the main mirror were as wide as the whole United States, its biggest bump would be smaller than a pencil eraser. Seriously! The team takes test pictures, focusing the telescope like you focus binoculars, except they are doing it by remote control from over a million kilometers away. There is no repair truck in deep space, so everything has to work. Then one day, the first real, full-power photo arrives on scientists' screens: millions of stars in one single frame. Gasps everywhere. Roman is officially awake and open for business. So what does its incredible camera actually see? Prepare to have your mind blown.
12:27The Monster Camera
Let's peek inside Roman's camera, because it is an absolute beast. It is called the Wide Field Instrument, and it snaps pictures that are three hundred megapixels each. Your family's phone camera? Maybe twelve or forty-eight megapixels. Roman's photos are so detailed that if you printed one at full quality, you would need a poster the size of a basketball court to see every dot. Each picture holds so much information that showing one on regular TV screens would take hundreds of screens all working together. And Roman does not see light quite like your eyes do. It sees infrared, which is a kind of light your eyes cannot detect, but you can feel it as warmth, like the heat from toast. Why infrared? Because it slips right through clouds of space dust like a superpower, letting Roman see stars and planets hiding behind the dust. Every day, Roman will beam home a mountain of data, enough to fill hundreds of laptops. Daily! But one gadget on board might be the coolest of all. It makes artificial eclipses on demand.
13:28Blocking Starlight
Remember the firefly on the lighthouse problem, where planets vanish in their star's glare? Roman carries a gadget built to fight the glare directly. It is called a coronagraph, and here is the simplest way to picture it: have you ever held up your hand to block the Sun so you could see a bird flying nearby? That is the idea! The coronagraph uses special masks and shape-shifting mirrors inside the telescope to block a star's blinding light almost perfectly, so the faint little planet beside it can finally show up in the picture. The mirrors adjust themselves thousands of times with movements smaller than a germ to keep the starlight blocked just right. If it works as well as scientists hope, Roman could photograph big planets around other stars directly, actually seeing the planet as its own little dot of light. That is like spotting the firefly while the lighthouse is still blazing. This gadget is a test run for future telescopes that might photograph a true twin of Earth. Speaking of wild planets, wait until you hear what kinds of worlds might be out there.
14:31The Weirdest Worlds
Buckle up, because exoplanets get WEIRD. Scientists have already found worlds so strange they sound made up, and Roman will likely find thousands more. There are lava planets, where the surface is a glowing ocean of melted rock and the temperature could melt a car in seconds. There are puffy planets as big as Jupiter but so light and fluffy that if you had a bathtub big enough, they would practically float like a beach ball. There is a planet where scientists think it could rain tiny bits of glass, sideways, in winds faster than any jet. And one famous planet is so dark it reflects almost no light at all, blacker than a chalkboard. Some planets zoom around their star in just a few hours, so a whole year there is shorter than your school day. Others have two suns in the sky, which means double sunsets, just like in the movies. Every new planet is a surprise package. But the planets everyone REALLY wants to find are the gentle ones. The cozy ones. The ones... a bit like ours.
15:29Oceans and Ice
Now for the planets that give scientists happy goosebumps: water worlds and ice worlds. Water is the number one ingredient scientists look for, because every living thing we know needs it. Some exoplanets might be entirely covered by oceans, no land at all, with waves rolling around the whole planet forever. Imagine a beach day where the beach never ends... because there is no beach, just water! Other worlds are frozen snowballs, wrapped in ice kilometers thick. But here is the exciting secret: even icy worlds can hide liquid oceans UNDER the ice, kept warm by the planet squishing and flexing inside. Right in our own solar system, moons like Europa probably have hidden oceans like that, with more water than all of Earth's oceans combined. So when Roman finds thousands of new planets, scientists will sort them like trading cards: too hot, too cold, too gassy... and then, every so often, one that lands in the special pile. The just-right pile. That pile has a wonderful nickname, and it comes from a fairy tale you already know.
16:30The Just-Right Zone
Scientists call it the Goldilocks zone. Remember Goldilocks? The porridge could not be too hot or too cold, it had to be just right. Planets are the same! If a planet orbits too close to its star, it roasts, and any water boils away. Too far, and it freezes solid. But in the middle, there is a just-right ring around every star where water can stay liquid, where rain can fall and rivers can flow. Earth sits perfectly inside our Sun's Goldilocks zone. Lucky us! Here is the thrilling part: Roman's discoveries will help scientists figure out how many Goldilocks planets our galaxy has. Early guesses say there could be hundreds of millions of them. Hundreds of millions of possible cozy worlds! Roman will even be able to detect planets in Goldilocks zones that are small and rocky like Earth, the hardest kind to find. Every one is a candidate for the biggest question humans have ever asked: is anybody out there? Hold that thought, because Roman has a second mission that is even more mysterious than planets. It is hunting something invisible.
17:31The Invisible Mystery
Ready for the strangest fact in this whole video? Everything you can see, every star, every planet, every galaxy, every pizza, every YOU, all of it together makes up only about five percent of the universe. Five percent! The other ninety-five percent is invisible stuff scientists call dark matter and dark energy. Dark matter is like an invisible friend whose footprints you can see in the snow, but you cannot see the friend. We know it is there because its gravity tugs on galaxies and holds them together like invisible glue. Dark energy is even weirder: it is a mysterious push that is making the whole universe stretch and expand faster and faster, like the greatest bread dough ever rising. Nobody on Earth knows what either one actually is. Nobody! It is one of the biggest unsolved mysteries in all of science. Roman's giant wide pictures will map millions of galaxies and measure how they are moving, gathering the best clues yet. A kid watching this video might grow up to crack the case. But how do you even photograph something invisible? Like this.
18:36Downtown Milky Way
One of Roman's biggest jobs is staring at the heart of our galaxy, the Milky Way. Our galaxy is shaped like a giant glittery pancake with a puffy middle, and that middle, called the bulge, is absolutely packed with stars, hundreds of millions of them crowded together. It is the busiest neighborhood in the entire galaxy. Roman will photograph the same crowded patch again and again, every few minutes, for weeks at a time, making a super-long movie of the galaxy's downtown. Why? Because with that many stars in frame, winks and gravity-flashes happen constantly. It is a planet-hunting jackpot. Wow-fact: in a single one of these pictures, there can be more stars than there are people in your whole country. And by comparing the photos over time, computers can spot a change in one tiny dot out of hundreds of millions. That is like noticing that one single sprinkle moved on a donut the size of a city. All those photos add up to an ocean of data. So how does it all get back to Earth? Great question.
19:35Pictures Across Space
Every single day, Roman beams home a truly gigantic pile of pictures, more data each day than any space telescope before it ever sent. The photos travel as invisible radio waves, flying across one and a half million kilometers of space at the speed of light, and they still take about five seconds to arrive. Giant dish antennas on Earth, some as wide as a swimming pool is long, catch the signals like enormous baseball gloves. Then supercomputers get to work, sorting millions of stars, hunting for winks and flashes, flagging anything interesting for scientists to check. And here is my favorite part: Roman's pictures will not be locked away in a secret vault. They get shared quickly with everyone, scientists, students, and curious kids around the world. That means discoveries can happen anywhere. A student in any country could look at fresh Roman data and spot something nobody else noticed. It has happened before with other telescopes, kids have actually helped find real planets! Want to know how regular people become planet hunters? That is next.
20:38Kids Can Help
Here is a secret grown-ups do not say enough: you do not need to be a professional scientist to help make real discoveries. It is called citizen science, and it is exactly what it sounds like, ordinary people helping with extraordinary science. Telescopes like Roman collect SO much data that even supercomputers need backup, because human eyes are amazingly good at spotting odd little patterns that computers miss. So scientists put real telescope data on websites where volunteers, including kids with a grown-up's help, look through star pictures and flag anything unusual. And it works! Volunteers have discovered new planets, found weird flickering stars, and even spotted galaxies scientists had never cataloged. Some school classes have made discoveries that ended up in real science papers with the students' names on them. Imagine telling your friends that YOU helped find a planet. Not in a game. A real planet, in real space, that will be on star maps forever. When Roman's flood of data arrives, planet hunters everywhere will be ready. But is Roman working alone out there? Nope. It is joining a telescope dream team.
21:45Telescope Dream Team
Space telescopes are like players on a sports team, each with a special skill. Hubble is the legend, the veteran player, taking sharp, beautiful pictures for over thirty years. The James Webb Space Telescope is the zoom master, it stares super deep at one small target and can even sniff out what a faraway planet's air is made of. And Roman? Roman is the wide receiver, seeing huge stretches of sky all at once. Here is how the teamwork goes: Roman scans a giant patch of sky and shouts, hey, I found ten thousand interesting things over here! Then Webb zooms way in on the very best ones for a close-up investigation. It is like one friend with binoculars spotting where the treasure is buried, and another friend with a shovel digging it up. Wow-fact: together, these telescopes can study a planet's size, its orbit, and even whether its sky has water vapor, from trillions of kilometers away, without ever leaving home. Teamwork makes the dream work, even in space. So how long will our new team player keep hunting?
22:48Five Year Adventure
Roman's main mission is planned to last five years. Five years of nonstop sky-scanning, day and night, because in space there are no cloudy days and no bedtime. Do the math with me: that is more than one thousand eight hundred days of photos. By the end, Roman will have measured over a BILLION galaxies and watched hundreds of millions of stars. But here is a fun secret about space telescopes: they love working overtime. Hubble was designed to last fifteen years and it is still going after more than thirty! If Roman stays healthy, scientists will happily keep it running long past five years, and it carries enough fuel to keep steady for a decade or more. Think about what that means for you. If you are eight years old right now, Roman could still be discovering brand-new planets when you are finishing high school. Some of the planets it finds might not even be studied closely until YOU are old enough to be the scientist studying them. Now let me show you something about Roman's pictures that is basically time travel.
23:48Photographing the Past
Every picture Roman takes is secretly a photo of the past. Sounds impossible? Here is why it is true. Light is the fastest thing in the universe, but space is SO enormous that even light needs serious travel time. Light from the Sun takes about eight minutes to reach Earth, so you always see the Sun as it looked eight minutes ago. Light from the next nearest star takes over four YEARS. And when Roman photographs stars near the center of our galaxy, that light left those stars around twenty-five thousand years ago, before anyone had invented writing, wheels, or pizza. The light has been zooming through space this whole time, and Roman catches it at the very end of its journey. So Roman is not just a telescope. It is a time machine that only looks backward. Some of the light in its photos is older than every pyramid on Earth. Try this tonight: look at any star and say, hello, ancient light! Because that is exactly what it is. And all that ancient light comes from a truly ridiculous number of stars.
24:49Counting the Stars
Let's play the biggest counting game ever. How many stars are in our galaxy, the Milky Way? Around one hundred billion, maybe more. Numbers that big are hard to feel, so let's make it real. If you counted one star every second, no eating, no sleeping, no bathroom breaks, it would take you over three thousand years to count them all. Your great-great-great-times-a-hundred grandkids would have to finish for you! And the Milky Way is just ONE galaxy. The universe holds hundreds of billions of galaxies, each with billions of stars of their own. Scientists say there are more stars in the universe than grains of sand on all the beaches of Earth combined. Every time you grab a handful of sand, imagine each grain as a blazing sun, probably with planets. THAT is the playground Roman is exploring. Suddenly one hundred thousand new planets sounds almost small, right? It is just the beginning of the beginning. But before Roman could explore anything, humans had to build it, and that happened in the cleanest room you have ever seen.
25:48The Cleanest Room
Space telescopes are not built in a regular workshop. They are built in a clean room, and clean does not even begin to describe it. The air is filtered so completely that it is thousands of times cleaner than a hospital operating room. Why so fussy? Because one single speck of dust on Roman's mirror could show up in photos like a boulder blocking the view. One fingerprint's worth of oil could ruin a sensor forever. So the engineers dress up in what they call bunny suits: head-to-toe white coveralls, hoods, masks, gloves, and booties, with only their eyes peeking out. They look like astronaut marshmallows! Before entering, they get blasted with air showers to blow off dust, and some clean rooms even use sticky floors to grab dirt off shoes. Wow-fact: regular humans shed about forty thousand tiny skin flakes every minute, which is exactly why all that gear exists. Gross but true! Inside, giant robotic cranes lift telescope pieces with the gentleness of a parent holding a baby bird. And once Roman was assembled, engineers did something that sounds bonkers: they tried their best to break it.
26:54Torture Testing Time
Before any telescope earns its ticket to space, it must survive torture testing, and yes, that is really what engineers call it. First, the shake test: Roman gets strapped to a giant vibrating table that rattles it exactly like a rocket launch, checking that no screw comes loose. Next, the sound test: enormous speakers blast it with noise as loud as the launch roar, sound so powerful it could shake your whole body. Then the big one: the thermal vacuum chamber. Roman goes inside a chamber the size of a house where all the air is pumped out and the temperature plunges colder than the coldest place on Earth, then technicians simulate the harsh conditions of space for weeks. If anything cracks, leaks, or glitches, engineers fix it and test again. And again. Why be so tough on it? Because space has no repair shops. Once Roman is a million and a half kilometers away, nobody is driving out with a toolbox. Every test passed means one less worry on launch day. So after all this work, what happens when the discoveries actually start rolling in?
27:55The Big Moment
Picture this moment, maybe a year or two from now. A scientist is sipping tea, scrolling through fresh Roman data, when suddenly... a wink. A tiny, repeating dip in a star's light. Small planet. Rocky. And it sits right in the Goldilocks zone. The scientist checks it once, twice, ten times. Hands start shaking. Other telescopes swing over to confirm it. And then the news flashes around the world: a new Earth-sized world in the just-right zone, one more clue in the greatest mystery ever. That is how discoveries happen, not with explosions, but with a quiet little wiggle in the data and a scientist whispering, whoa. It has happened before with other telescopes, and with Roman finding planets by the tens of thousands, moments like this could happen again and again. Each discovery gets checked by teams all over the planet, because in science, double-checking is the golden rule. Every confirmed world goes into the great catalog of planets, the map your generation will inherit. Which brings me to the most important part of this whole video: you.
28:56The Next Explorers
Here is the truth: Roman will find the planets, but it cannot study them all. That job belongs to the future, and the future is sitting there watching this video. Every big space mission needs thousands of different helpers. Engineers who design and build. Astronomers who study the data. Computer programmers who write the code that spots the winks. Artists who paint what new planets might look like. Writers who explain discoveries. Teachers who inspire the next round of explorers. Every one of those people started exactly where you are: a kid asking questions. Nancy Grace Roman started with a backyard astronomy club. The engineers who built this telescope once built with blocks and broke their toys to see inside. Wow-fact: many planets Roman discovers will not be closely studied for decades, which means the scientist who finally explores planet number 99,999 might be doing homework right now. Maybe multiplication homework. Maybe yours. Stay curious, keep asking why, and keep looking up. Now let's blast through the coolest stuff you just learned, because you know a LOT now.
30:00Recap and Challenge
Recap time, rapid fire! On August 30, the Nancy Grace Roman Space Telescope blasts off to hunt for around one hundred thousand brand-new planets. It sees one hundred times more sky in one photo than Hubble, with a monster three-hundred-megapixel camera. It catches planets by spotting winking stars and by using gravity itself as a magnifying glass, a trick Einstein predicted over a century ago. It will find lonely rogue planets drifting with no sun, map the invisible mystery of dark energy, and photograph starlight that is twenty-five thousand years old. And it is named after Nancy Grace Roman, the kid with a stargazing club who grew up to become the Mother of Hubble. Not bad for one school-bus-sized robot! Here is your challenge tonight: step outside with your family, find the brightest star you can, and tell them this: that star might have planets nobody has ever seen, and a telescope named Roman is about to go looking. Then say hello to that ancient light. Keep wondering, keep exploring, and remember, somewhere out there, one hundred thousand worlds are waiting... for you.
