World's largest telescope unveils first images of galaxies in stunning detail

Yahoo7 hours ago

The first images from a new telescope in Chile were released this week, featuring extraordinarily detailed scenes from deep space. And more are expected to follow the debut series from the long-awaited Vera Rubin Observatory, which now houses the largest telescope in the world.
More than two decades in the making, the giant U.S.-funded telescope sits perched at the summit of Cerro Pachon in central Chile, where dark skies and dry air provide ideal conditions for observing the cosmos. The first-look images captured star-forming regions as well as distant galaxies.
One of them is a composite of 678 exposures taken over just seven hours, capturing the Trifid Nebula and the Lagoon Nebula — both several thousand light-years from Earth — glowing in vivid pinks against orange-red backdrops.
The image reveals these stellar nurseries within our Milky Way in unprecedented detail, with previously faint or invisible features now clearly visible.
Another image offers a sweeping view of the Virgo Cluster of galaxies.
The team also released a video dubbed the "cosmic treasure chest," which begins with a close-up of two galaxies before zooming out to reveal approximately 10 million more.
"The Rubin Observatory is an investment in our future, which will lay down a cornerstone of knowledge today on which our children will proudly build tomorrow," said Michael Kratsios, director of the White House Office of Science and Technology Policy.
Equipped with an advanced 8.4-meter telescope and the largest digital camera ever built, the Rubin Observatory is supported by a powerful data-processing system.
Later this year, it will begin its flagship project, the Legacy Survey of Space and Time (LSST). Over the next decade, it will scan the night sky nightly, capturing even the subtlest visible changes with unmatched precision.
Elana Urbach, a commissioning scientist on the project, told CBS News partner BBC News that one of the observatory's main goals is to "understand the history of the universe." That would mean having the ability to see galaxies or supernova explosions that occurred billions of years ago, according to BBC News.
"So, we really need very sharp images," Urbach said.
The design of the telescope allows it to capture a lot of light, and, in turn, observe objects that are very far away, Guillem Megias, an optics expert at the Rubin Observatory, told BBC News. Megias noted that, in astronomy, "really far away ... means they come from earlier times."
The observatory is named after pioneering American astronomer Vera C. Rubin, whose research provided the first conclusive evidence for the existence of dark matter — a mysterious substance that does not emit light but exerts gravitational influence on galaxies.
Dark energy refers to the equally mysterious and immensely powerful force believed to be driving the accelerating expansion of the universe. Together, dark matter and dark energy are thought to make up 95 percent of the cosmos, yet their true nature remains unknown.
The observatory, a joint initiative of the U.S. National Science Foundation and Department of Energy, has also been hailed as one of the most powerful tools ever built for tracking asteroids.
In just 10 hours of observations, the Rubin Observatory discovered 2,104 previously undetected asteroids in our solar system, including seven near-Earth objects — all of which pose no threat.
For comparison, all other ground- and space-based observatories combined discover about 20,000 new asteroids per year.
Rubin is also set to be the most effective observatory at spotting interstellar objects passing through the solar system.
More images from the observatory are expected to be released later Monday.

Vera Rubin Observatory reveals jaw-dropping first images from world's largest telescope

This morning, the world's largest telescope revealed its first-ever images of space—and they're pretty jaw-dropping. The images come courtesy of the NSF–DOE Vera C. Rubin Observatory, a scientific facility funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science. Located at the summit of Cerro Pachón in Chile, the facility is the product of more than 20 years of work. Its space camera—embedded in the hulking Large Synoptic Survey Telescope (LSST) —is about the size of a small car and includes a sensor array of three billion pixels, the most sensors ever used in a telescope camera. According to a press release from the Rubin Observatory, it's expected to generate an 'ultrawide, ultra-high-definition time-lapse record of the Universe.' 'It will bring the sky to life with a treasure trove of billions of scientific discoveries,' the release reads. '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 most efficient Solar System discovery machine ever built' In just its first 10-hour test observation, unveiled today, the LSST managed to capture images which include millions of galaxies and Milky Way stars, as well as more than 2,000 never-before-seen asteroids within our Solar System. Taken together, the photos illustrate a technicolor view of space at a mind-boggling scale—but the 10 million galaxies photographed by the LSST represent only 0.05% of the roughly 20 billion galaxies that the camera is expected to record within the next decade. The primary goal of the LSST is to complete a 10-year survey of the Southern hemisphere sky, capturing hundreds of images and around 20 terabytes of data per night throughout that period. Per the Rubin Observatory, this massive influx of data will make the LSST 'the most efficient and effective Solar System discovery machine ever built.' All of the captured data will be made available online, allowing astronomers across the globe to access countless new findings without physical access to the telescope. The LSST is designed to advance four main areas of study: Understanding the nature of dark matter and dark energy; creating an inventory of the Solar System; mapping the Milky Way; and exploring the transient optical sky, i.e. studying objects that move or change in brightness. Experts predict that, given its capacity to identify millions of unseen asteroids, comets, and interstellar objects, the camera could even help protect the planet by spotting objects on a trajectory toward the Earth or Moon. 'NSF–DOE Rubin Observatory will capture more information about our Universe than all optical telescopes throughout history combined,' Brian Stone, chief of staff at the National Science Foundation, said in a press release. 'Through this remarkable scientific facility, we will explore many cosmic mysteries, including the dark matter and dark energy that permeate the Universe.'

TNB Tech Minute: Main Street Banks Could Get Opening to Join Stablecoin Market - Tech News Briefing

Full Transcript This transcript was prepared by a transcription service. This version may not be in its final form and may be updated. Speaker 1: Here's your TNB Tech minute for Monday, June 23rd. I'm Victoria Craig for the Wall Street Journal. Main Street banks worried about getting left behind by the push into crypto might soon get an opening. The Journal exclusively reports that financial technology giant Fiserv has plans to launch a stablecoin and platform that can be used by clients including 3,000 regional and community banks. A broad shift to crypto would put deposits at those more local banks at risk, because they're reliant on those deposits to make loans. If customers were to pull deposits and put the funds into stablecoins, it would leave those banks less room to lend and squeeze a critical revenue source. Elsewhere, German auto parts company Continental said today it's partnering with semiconductor maker GlobalFoundries to design its own vehicle computer chips. The new organization called Advanced Electronics & Semiconductor Solutions will design and test chips tailored for automotive products of its spinoff, Aumovio. Continental said the new unit will reduce geopolitical risk and make the company more self-reliant. And finally, a US-funded space observatory perched in the Andes mountains in Chile released its first images of deep space using the world's largest digital camera. It's the first time a telescope has been able to peer this far and wide into the cosmos. And for the next 10 years, the observatory will take photos of the southern sky at 30-second intervals every three to four nights. Scientists hope the project called The Legacy Survey of Space and Time will inventory the solar system, map the Milky Way, catalog billions of transient space objects, and unlock the mysteries of dark matter and energy.

See the Mind-Blowing First Images From a Revolutionary New Telescope

It's been more than two decades since the Vera C. Rubin Observatory was first conceived in a 'back-of-the-napkin' sketch. With construction on this huge telescope finally nearing completion, Rubin scientists unveiled its dazzling first images at a livestreamed event in Washington D.C. on Monday, June 23. Perched atop a mountain in the Chilean Andes, the Rubin Observatory boasts the largest digital camera ever built. The telescope, overseen by the U.S. National Science Foundation (NSF) and the Department of Energy (DOE), recently used this car-sized, 3.2-gigapixel camera to conduct just over 10 hours of test observations. In this short period, Rubin observed millions of galaxies and Milky Way stars as well as 2,104 never-before-seen asteroids, according to an NSF release. Rubin scientists unveiled a 'sneak-peak' of some of these images just after midnight on Monday, but those were just the tip of the iceberg. During today's event, Rubin scientists engaged digital warp-drive, using a program called Skyviewer to zoom deep into the observatory's images and reveal their finest details in striking clarity. This platform is freely available to all, allowing both researchers and non-experts to explore the cosmos like never before. The ultra-high-definition images showcase Rubin's ability to capture swirling galaxies, colorful nebulae, and billions of stars in unprecedented detail. 'We hope you see these images as beautiful. They're also a little different than what you're used to seeing—actually, significantly different,' said Steve Ritz, a professor of physics at the University of California Santa Cruz and project scientist for Rubin construction. In most astronomical pictures, the spaces between objects are inky black voids. 'But that's not what you saw here. What you saw was that inky black space is actually full of stuff,' Ritz said. 'It's full of galaxies—it's full of all kinds of interesting things. And it's because of Rubin's unique combination of capabilities that we're able to bring that all out.' The observatory's first wave of discoveries includes supernovae and distant galaxies that can help astronomers study the expansion of the universe. By observing these objects, Rubin may even help solve the Hubble tension—a discrepancy between different measurements of the universe's current expansion rate, known as the Hubble constant. Rubin also discovered seven new near-Earth asteroids. They pose no danger to our planet, but finding them demonstrates how the observatory can rapidly identify previously unknown asteroids and help astronomers assess potential threats to Earth. In total, all other ground and space-based observatories discover roughly 20,000 new asteroids per year, but Rubin scientists estimate that this single observatory will discover millions within the first two years of its Legacy Survey of Space and Time (LSST). This decade-long survey of the night sky will produce an ultrawide, ultra-high-definition time-lapse record of the universe. The data should help scientists uncover the true natures of dark matter and dark energy, catalog the solar system, explore the changing sky, and understand the structure and functioning of our Milky Way galaxy. Rubin will observe the cosmos on an automated schedule using its 27.6-foot (8.4-meter) Simonyi Survey telescope—whose unique three-mirror design includes the largest convex mirror ever made. Each 30-second exposure will cover an area about 45 times the size of the full Moon. Then, the enormous LSST camera will capture wide-field images and stitch them together to create a complete view of the southern sky every three nights. Dedicated computer facilities will process the data in real time. If these facilities detect any changes in the night sky, they will issue global alerts within minutes, allowing other telescopes to pivot to the area of interest. The observatory's findings will then be compiled into a massive archive that will vastly increase the amount of data available to scientists. Researchers led by astronomer Meg Schwamb at Queen's University Belfast recently estimated that Rubin could triple the number of known near-Earth objects (NEOs) from about 38,000 to 127,000, detect 10 times more trans-Neptunian objects than currently cataloged, and provide colorful, detailed observations of more than 5 million main-belt asteroids—up from roughly 1.4 million. Thus, the wealth of data Rubin produced in this first test is only the beginning. Already, the observatory has compiled a 'very complex' dataset, but Clare Higgs—the astronomer on Rubin's education and public outreach team—has been working hard to make the data accessible to all. In addition to exploring Rubin's images through Skyviewer, people will eventually be able to experience sky survey data through sound. Data sonification, the practice of assigning audible representations to information and processes, offers a powerful alternative to visualizations, according to the observatory's website. Higgs is also excited about getting Rubin data into classrooms. The observatory's education program will provide online astronomy investigations based on real Rubin data that are designed for students of all ages, from middle schoolers to college students. 'One of the things I'm really excited about,' Higgs said, 'is the fact that we're about to see a generation of students who can see Rubin data in their classrooms in high school, and then perhaps choose to study that in university, and then go on to maybe make the next amazing discovery that will be in that treasure trove of data.'
