This factor you’re , in regards to the dimension of an SUV and weighing almost 2.8 tons, is definitely a digital camera. Not simply any digital camera—the most important digital camera ever constructed. It comprises an enormous 3200-megapixel CCD sensor array.
To higher perceive the decision, let’s put it this fashion: the human eye can’t even understand the complete element of its photographs. You know the way folks say, “see the massive image”? Properly, that is the most important image. Displaying a single picture captured by it could require round 400 4K TVs—that’s principally 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 would possibly surprise, doesn’t it want a telescope to seize area photographs? Sure, and this digital camera has been mounted on an 8-meter telescope on the Rubin Observatory, which has been beneath growth for over 20 years. Now, this observatory is the most important 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 would possibly ask, “How is that this any completely different from earlier photographs?” To start with, what you’re seeing now could be simply 2% of your complete picture taken by the world’s largest digital camera. In different phrases, the complete picture is 50 instances bigger than what’s on display screen.
And that’s solely a single body. This digital camera will document a number of such frames all through the evening, making a kind of timelapse film of the evening sky, with each body at this astonishing decision. It would scan your complete southern sky each 3–4 nights—after which do it over 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 consistently scans and data ultra-high-resolution movies of your complete sky.
Let’s check out the observatory itself, as a result of it additionally consists of some outstanding improvements.
The total title is the Vera C. Rubin Observatory, positioned in northern Chile, on high of a mountain 2682 meters excessive. Chile hosts many telescopes as a result of its supreme location and clear skies, however this one stands out for 3 causes.
First is the world’s largest digital camera, formally within the Guinness Guide of Data. With 3200 megapixels, every picture is manufactured from 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 novel three-mirror design, it’s quick. We’re speaking 300 tons, however it might modify place in seconds, not like different massive telescopes that take minutes. The observatory group proudly says, “Different telescopes are like vehicles; ours is sort of a jet.”
The third piece is the information heart. It data terabytes of information each evening, packaging them into ~20 TB chunks. For reference, this drive right here is 4 TB—and Rubin fills 5 of those each evening. And keep in mind, it’s sitting atop a distant mountain in Chile. All this knowledge travels through 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 seemed like darkish empty area is now bursting with mild. Nearly each pixel reveals some sort 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 are able to see, and makes use of it to encode distance. So, we’re basically trying on the universe in 3D.
These clusters and their distribution reveal how the universe has expanded over time, and even provide clues about darkish matter and darkish power. That’s why this observatory is called after Vera C. Rubin, a scientist who studied the motion of galaxies and gave us the primary strong proof of darkish matter.
Extremely, this single picture comprises 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 size we’re speaking about.
this identical area once more, you’ll see some objects labeled—they had been beforehand identified. However most are unnamed, by no means earlier than seen by people.
Each evening, Rubin will scan the sky time and again. Scientists will create a template picture for every space and examine new photographs to detect adjustments utilizing a method known as distinction imaging.
“However what might change evening to nighttime?” you ask. Properly, three issues: brightness, motion, and pulsation.
A sudden brightness? That could possibly be a supernova. Speedy motion? Probably an asteroid or interstellar object. Delicate 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 speak about asteroids. They transfer quick, too quick to look in static photographs. However with lengthy publicity, they go away coloured trails. These colours—purple, inexperienced, and blue—signify completely different filters utilized in successive photographs. Customized software program identifies and removes them from nonetheless photographs, however retains their knowledge. If motion is uncommon, it raises an alert.
Watch this animation from 10 hours of remark. The galaxies stay nonetheless, however the asteroids flash by. Each asteroid you see right here was newly found.
Then we see what number of had been found evening after evening, and at last, their positions within the Photo voltaic System. The sunshine-blue slice reveals newly discovered asteroids in a tiny sector of the bigger inhabitants.
In just some nights, Rubin found over 2,000 new asteroids. Seven of them are labeled Close to-Earth Objects, however don’t fear—none pose a risk. Nonetheless, Rubin acts like an early warning system, anticipated to find 5 million new asteroids in two years—5 instances 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 of examine their habits in real-time, like an area documentary.
Better of all? Rubin shares its knowledge freely. Not only for scientists—for everybody. Academics, 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 sort of stay 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, protecting 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 may 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 Approach. Dr. Rubin studied galaxies like this within the Nineteen 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. Take a look at the tidal tails and streams stretching throughout area. Others seem shut however are literally thousands and thousands of light-years aside.
The tiny red-orange dots? These are distant galaxies, displaying us the early universe. This can be a time machine in motion.
You may even toggle asteroid trails—usually hidden to cut back muddle. Every shade marks a distinct publicity, and the path’s form displays the asteroid’s velocity and course.
The spiky stars? They’re from our personal Milky Approach—so shut, their brightness causes diffraction spikes within the digital camera.
Should you discover one thing you want, you may create a hyperlink at that actual zoom degree and share it. You may focus on, examine, and hold discovering.
Zooming out reveals tough edges—these are the areas the digital camera hasn’t imaged but. However each evening, 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 provide you with goosebumps, I don’t know what’s going to. Both you don’t know sufficient but—or worse—you don’t care. However in the event you do, your mission—must you 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 one can cease you. There’s greater than sufficient to go round.
And when you’ve chosen your star—watch it, examine it, be impressed.
That is my star.
