This factor you’re taking a look at, concerning the dimension of an SUV and weighing almost 2.8 tons, is definitely a digital camera. Not simply any digital camera—the biggest digital camera ever constructed. It accommodates an enormous 3200-megapixel CCD sensor array.
To raised perceive the decision, let’s put it this fashion: the human eye can’t even understand the complete element of its pictures. You know the way folks say, “see the large image”? Properly, that is the largest image. Displaying a single picture captured by it could require round 400 4K TVs—that’s mainly a whole basketball courtroom filled with screens.
However what precisely will this digital camera seize? Essentially the most detailed video of the universe ever recorded.
You may marvel, doesn’t it want a telescope to seize house pictures? Sure, and this digital camera has been mounted on an 8-meter telescope on the Rubin Observatory, which has been below growth for over 20 years. Now, this observatory is the biggest astronomical discovery machine ever created.
And this machine made its first public launch on June 23, 2025. Right here’s the very first picture proven to the world.
You may ask, “How is that this any totally different from earlier pictures?” Initially, what you’re seeing now could be simply 2% of the complete picture taken by the world’s largest digital camera. In different phrases, the complete picture is 50 occasions bigger than what’s on display screen.
And that’s solely a single body. This digital camera will file a number of such frames all through the night time, making a kind of timelapse film of the night time sky, with each body at this astonishing decision. It’ll scan the complete southern sky each 3–4 nights—after which do it yet again.
That is what units it other than earlier telescopes. Whereas conventional telescopes are like highly effective binoculars specializing in a particular spot, the Rubin Observatory is extra like a surveillance digital camera that continually scans and data ultra-high-resolution movies of the complete sky.
Let’s check out the observatory itself, as a result of it additionally consists of some exceptional improvements.
The complete identify is the Vera C. Rubin Observatory, situated in northern Chile, on high of a mountain 2682 meters excessive. Chile hosts many telescopes attributable to its superb location and clear skies, however this one stands out for 3 causes.
First is the world’s largest digital camera, formally within the Guinness Ebook of Information. With 3200 megapixels, every picture is product of extra pixels than the human eye can understand. One Rubin picture covers a sky space equal to 45 full moons. If printed, it could be as massive as a basketball courtroom. To view it correctly, they developed a particular web-based viewer—accessible to everybody, not simply scientists. I’ll present you the way it works shortly.
Second is the Simonyi Survey Telescope. With an 8.4-meter mirror and a singular three-mirror design, it’s quick. We’re speaking 300 tons, however it will probably alter place in seconds, in contrast to different massive telescopes that take minutes. The observatory staff proudly says, “Different telescopes are like automobiles; ours is sort of a jet.”
The third piece is the info middle. It data terabytes of information each night time, packaging them into ~20 TB chunks. For reference, this drive right here is 4 TB—and Rubin fills 5 of those each night time. And keep in mind, it’s sitting atop a distant mountain in Chile. All this knowledge travels by way of fiber-optic cables to knowledge facilities within the US, UK, and France.
Again to the primary picture. What are we seeing? A universe stuffed with stars and galaxies. What as soon as appeared like darkish empty house is now bursting with mild. Nearly each pixel reveals some type of celestial object.
You’re seeing spiral galaxies, elliptical galaxies, and galaxy clusters. The nearer, bluer ones are spirals, and the farther redder ones are ellipticals. These colours aren’t random—the digital camera captures a broader mild spectrum than we will see, and makes use of it to encode distance. So, we’re primarily wanting on the universe in 3D.
These clusters and their distribution reveal how the universe has expanded over time, and even supply clues about darkish matter and darkish power. That’s why this observatory is known as after Vera C. Rubin, a scientist who studied the motion of galaxies and gave us the primary stable proof of darkish matter.
Extremely, this single picture accommodates almost 10 million galaxies. Not stars—galaxies. Think about photographing 10 million folks, after which realizing every one represents 100 billion folks. That’s the dimensions we’re speaking about.
Taking a look at this identical area once more, you’ll see some objects labeled—they have been beforehand recognized. However most are unnamed, by no means earlier than seen by people.
Each night time, Rubin will scan the sky repeatedly. Scientists will create a template picture for every space and examine new pictures to detect adjustments utilizing a way referred to as distinction imaging.
“However what may change night time to nighttime?” you ask. Properly, three issues: brightness, motion, and pulsation.
A sudden brightness? That may very well be a supernova. Speedy motion? Presumably an asteroid or interstellar object. Refined pulsation? That is perhaps a pulsar.
And keep in mind, this picture reveals simply a part of the southern sky. Rubin will observe 40 billion celestial objects over the following 10 years, not simply photographing them however video recording their habits.
Let’s discuss asteroids. They transfer quick, too quick to look in static pictures. However with lengthy publicity, they go away coloured trails. These colours—crimson, inexperienced, and blue—symbolize totally different filters utilized in successive photographs. Customized software program identifies and removes them from nonetheless pictures, however retains their knowledge. If motion is uncommon, it raises an alert.
Watch this animation from 10 hours of commentary. The galaxies stay nonetheless, however the asteroids flash by. Each asteroid you see right here was newly found.
Then we see what number of have been found night time after night time, and eventually, their positions within the Photo voltaic System. The sunshine-blue slice reveals newly discovered asteroids in a tiny sector of the bigger inhabitants.
In only a few nights, Rubin found over 2,000 new asteroids. Seven of them are labeled Close to-Earth Objects, however don’t fear—none pose a menace. Nonetheless, Rubin acts like an early warning system, anticipated to find 5 million new asteroids in two years—5 occasions greater than all astronomers discovered within the final 200 years.
The digital camera additionally tracks exploding stars—supernovae—and variable stars whose brightness adjustments in minutes. For the primary time, we’ll be capable to research their habits in real-time, like an area documentary.
Better of all? Rubin shares its knowledge freely. Not only for scientists—for everybody. Lecturers, college students, fans—unfold the phrase. I’ll go away hyperlinks within the description under. Save them. As a result of for the following decade, we’ll be watching a type of dwell stream of the universe.
Now, let me present you ways. This web-based viewer works identical to Google Maps, however for the universe. The view you’re seeing is 55 million light-years away, overlaying the Virgo Cluster. Simply 14 levels of sky, and but it consists of over 3 trillion pixels from simply seven nights of Rubin observations.
You’ll be able to zoom and discover every pixel. For instance, that is Messier 49, an outdated star elliptical galaxy, its yellow shade indicating age. Over right here, we see youthful, blue galaxies, the stellar nurseries of the cosmos.
That is Messier 61, a spiral galaxy like our Milky Manner. Dr. Rubin studied galaxies like this within the Seventies and helped show the existence of darkish matter.
Some galaxies have solely two arms—like NGC 4334. Others seem as discs as a result of we’re viewing them edge-on, like NGC 4343.
Right here, galaxies are merging. Have a look at the tidal tails and streams stretching throughout house. Others seem shut however are literally tens of millions of light-years aside.
The tiny red-orange dots? These are distant galaxies, exhibiting us the early universe. It is a time machine in motion.
You’ll be able to even toggle asteroid trails—usually hidden to scale back muddle. Every shade marks a distinct publicity, and the path’s form displays the asteroid’s velocity and route.
The spiky stars? They’re from our personal Milky Manner—so shut, their brightness causes diffraction spikes within the digital camera.
For those who discover one thing you want, you’ll be able to create a hyperlink at that precise zoom stage and share it. You’ll be able to talk about, examine, and preserve discovering.
Zooming out reveals tough edges—these are the areas the digital camera hasn’t imaged but. However each night time, it provides extra tiles and fills within the gaps—constructing probably the most full map of the sky we’ve ever had.
And keep in mind, we’ve already seen issues by no means seen earlier than. Our eyes and screens alone aren’t sufficient. That’s why this software exists.
If this doesn’t offer you goosebumps, I don’t know what’s going to. Both you don’t know sufficient but—or worse—you don’t care. However should you do, your mission—do you have to select to simply accept it—is to unfold the curiosity.
Look, there are extra stars than folks on Earth. So choose one. Declare it. No person can cease you. There’s greater than sufficient to go round.
And when you’ve chosen your star—watch it, research it, be impressed.
That is my star.
