Rubin Observatory's First Images Just Unveiled the Universe as We've Never Seen It Before
Editor's Note (6/23/25): This story will be updated with additional images and details shortly after 11 A.M. EDT.
Welcome to a mind-blowing new era of astronomy.
The long-awaited Vera C. Rubin Observatory, a cutting-edge new telescope perched atop a mountain in Chile, is releasing its first images of the universe on June 23—and its views are just as jaw-dropping as scientists hoped. (The observatory is holding a celebratory event today at 11 A.M. EDT to reveal additional images that you can watch a livestream of on YouTube. In addition, organizations are hosting watch parties open to the public around the world.)

The new images come from only 10 hours of observations—an eyeblink compared with the telescope's first real work, the groundbreaking, 10-year Legacy Survey of Space and Time (LSST) project. On display are billowing gas clouds that are thousands of light-years away from our solar system and millions of sparkling galaxies—all emblematic of the cosmic riches that the observatory will ultimately reveal.
'In a lot of ways, it almost doesn't matter where we look,' said Aaron Roodman, a physicist at Stanford University and program lead for the Rubin Observatory's LSST Camera, in a preview press conference held on June 9.
'We're going to see changing objects; we're going to see moving objects; we're going to get a view of thousands and thousands of galaxies of stars in any field we look at,' he said. 'In some sense, we could have looked anywhere and gotten fantastic images.'
In the end, the team decided to share several mosaics of images from the observatory that highlight its extremely wide field of view, which can capture multiple alluring targets in a single snapshot.
The view above of the Triffid Nebula (top right) and Lagoon Nebula includes data from 678 individual images captured by the Rubin Observatory. Scientists stack and combine images in this way to see farther and fainter into the universe. The Triffid Nebula, also known as M20, and the Lagoon Nebula, also known as M8, are star-forming regions both located several thousand light-years away from Earth in the constellation Sagittarius.
The observatory also captured an initial view of the Virgo Cluster, a massive clump of galaxies located in the constellation of the same name. Individual detail images (at top and below) show a mix of bright Milky Way stars against a backdrop of myriad more distant galaxies. In addition, the team has released a teaser video of a stunning zoomable view of some 10 million galaxies that was created by combining some 1,100 images taken by the new observatory.
The Rubin Observatory has promised to reveal additional imagery during the unveiling event later today, including the full video of the massive view of countless galaxies and another video depicting the more than 2,000 asteroids the telescope has already discovered in just 10 hours of observations.
These first glimpses from Rubin showcase the observatory's unprecedented discovery power. The telescope will survey the entire southern sky about once every three days, creating movies of the cosmos in full color and jaw-dropping detail.
'We've been working on this for so many years now,' says Yusra AlSayyad, an astronomer at Princeton University and the Rubin Observatory's deputy associate director for data management. 'I can't believe this moment has finally come.'

Check out the first stunning images from the world's largest digital camera
The NSF–DOE Vera C. Rubin Observatory in Chile has unveiled its first images, showcasing the astonishing capabilities of its groundbreaking 3,200-megapixel digital camera, the largest in the world. The new $800 million observatory took a decade to build and represents a significant step forward in astronomical research and exploration. Situated at 8,684 feet on Cerro Pachón, near the edge of the Atacama Desert, the facility benefits from a dry and remarkably stable atmosphere, conditions that make it well-suited for astronomical observation. Recommended Videos The stunning images, captured during a trial phase that began a couple of months ago, include breathtaking views of the Trifid Nebula and the Lagoon Nebula, both stellar nurseries located several thousand light-years away. The images were created from 678 separate exposures taken across seven hours, revealing intricate details and previously invisible features in vibrant colors. 'NSF–DOE Rubin Observatory will capture more information about our universe than all optical telescopes throughout history combined,' said Brian Stone, the acting NSF director. 'Through this remarkable scientific facility, we will explore many cosmic mysteries, including the dark matter and dark energy that permeate the universe.' The Rubin Observatory is set to conduct the Legacy Survey of Space and Time (LSST), a 10-year endeavor that's expected to get underway later this year. The ambitious project aims to map the entire southern sky every three to four nights. The tantalizing result will be an ultra-wide, ultra-high-definition time-lapse record of the universe, yielding potentially billions of scientific discoveries. 'The images will reveal asteroids and comets, pulsating stars, supernova explosions, far-off galaxies and perhaps cosmic phenomena that no one has seen before,' the Rubin Observatory said. Across its first 10 hours of observation, the Rubin Observatory has already made notable discoveries, including more than 2,100 previously undetected asteroids, at the same time capturing millions of galaxies and Milky Way stars. Sandrine Thomas, deputy director of Rubin Construction and associate director of Rubin Observatory for Rubin Summit Operation, said her team was 'thrilled' to share the observatory's first images with the world. 'It's a proud moment for our whole team,' she said. 'While we still have a few important months of commissioning and testing ahead, everything we learn now brings us closer to full science operations later this year. Today is just the beginning.'

1,000-year-old pre-Inca mummy discovered just half a metre below a street in Lima
The remains, identified as a woman aged 20 to 30, were wrapped in a bundle that still had visible dark brown hair. Alongside the body, archaeologists found nine ceramic vessels, including a painted bottle depicting a fisherman in a headdress - suggesting the woman belonged to the Chancay culture, a coastal fishing society that thrived between 1000 and 1470 AD. The discovery is part of an ongoing archaeological monitoring program by the national gas company Cálidda, which has recovered over 2,200 artefacts during infrastructure projects in Lima.

Telescope built in the Bay Area captures photos of space like never before
The first images of the universe from the world's largest digital camera were released on Monday. SLAC National Accelerator Laboratory in Menlo Park unveiled the never-before-seen images of our universe. The Rubin Observatory sits on the summit of Cerro Pachón in Chile with the digital camera scanning the sky to create an ultra-wide, ultra-high definition timelapse of our universe Phil Marshall is passionate about uncovering the secrets to our incredible universe. He is the Deputy Director of Operations at Rubin Observatory. Marshall has been waiting for years to see the very first images from Rubin Observatory's digital camera, capturing the cosmos in a way unlike anything else. "I think I described it as a dream come true," said Marshall. "I've been thinking about this for so long. It's kind of amazing that it's here now. On the other hand, this is just the beginning. It's very exciting to be at the start of the survey, just about able to do all the investigations of the universe that we've been planning for so long. These sharper, clearer images of our universe are like nothing we've seen before with millions of galaxies in each snapshot in amazing detail. "Honestly, it's just mind-blowing," said Risa Wechsler, Stanford & SLAC Director of Kavli Institute for Particle Astrophysics and Cosmology. "It makes me very, very excited about the future of astrophysics. Previously, we've been able to see a lot of the sky or we've been able to go deep and what is really different about these images is that it's both. It really is sort of simultaneously a very wide area so that you can see many galaxies you know, millions and millions of galaxies in one snapshot and then also go really deep and going deep will do two things. One, for the nearby galaxies, you can really see all the way into the outskirts, and you can see all these incredible details of how they formed and then for the far away galaxies, you just get so many of them. " "We should be able to see the entire sky at that level of sensitivity, that level of spatial detail, and with that time resolution, to see how the university evolves, how variable stars are varying, how supernovae are exploding, how asteroids are moving within our own solar system," said Adam Bolton, SLAC Senior Scientist. "We have all that within a digital database that we can query in any way we could imagine. That's something that's never existed before." Every night at Rubin Observatory in Chile, the digital camera will scan the sky, capturing a new 3,200-megapixel image every 40 seconds, providing near-real-time, valuable data of our universe. "It really makes it clear that the universe is full of galaxies," said Marshall. "Our galaxy is full of stars and our universe is full of galaxies," said Marshall. "There's billions of them to be observed and you can see that in the images now, each one of those galaxies itself contains billions of stars, and so it's very humbling to see these images. It puts us right in our place, so to speak." Marshall said these first images are truly awe-inspiring as scientists move one step closer to unlocking the mysteries of our universe. The Rubin Observatory will continue capturing images of our universe in a 10-year scientific mission. The amount of data gathered by Rubin Observatory in its first year alone will be greater than that collected by all other optical observatories combined. NSF-DOE Vera C. Rubin Observatory is jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science. SLAC is operated by Stanford University for the DOE.
