Groundbreaking Vera Rubin Observatory reveals first images of deep space
23 June 2025 20:03
Washington (AFP) Breathtaking, swirling, multicolored galaxies and star-forming regions were revealed on Monday in the first images of deep space captured by the Vera Rubin Observatory in Chile.More than two decades in the making, the giant US-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.One of the debut images is a composite of 678 exposures taken over 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.It features an advanced 8.4-meter telescope and the largest digital camera ever built, supported by a powerful data-processing system.
Roughly the size of a car and weighing 2.8 tons, the camera captures 3,200-megapixel images -- more than three times the resolution of the next most powerful instrument, Japan's Hyper Suprime-Cam, which records at 870 megapixels.
10-year flagship project Later this year, the observatory 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.The observatory, which cost roughly $800 million, 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% of the cosmos, yet their true nature remains unknown.The observatory, a joint initiative of the US 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 were expected to be released later Monday.Chile hosts telescopes from more than 30 countries, including some of the world's most powerful astronomical instruments -- among them the ALMA Observatory, the most advanced radio telescope on Earth.The upcoming Extremely Large Telescope, slated to begin operations in 2027, will enable observations of previously unreachable cosmic distances.Northern Chile's deserts, nestled between the Pacific Ocean and the Andes mountains, offer the clearest skies on the planet, thanks to minimal cloud cover and an arid climate.
The Cerro Tololo Observatory has been the site of major discoveries, including the universe's accelerated expansion -- a breakthrough that earned Americans Saul Perlmutter and Adam Riess, along with Australian Brian Schmidt, the 2011 Nobel Prize in Physics.

Chile observatory captures the universe with 3,200-megapixel camera
27 June 2025 18:09 SANTIAGO (Reuters) Chile's Vera C. Rubin Observatory, which boasts the world's largest digital camera, has begun displaying its first images of the cosmos, allowing astronomers to figure out how the solar system formed and even whether an asteroid poses a threat to on Pachon Hill in the northern region of Coquimbo, the 8.4-meter (27-1/2-foot) telescope has a 3,200-megapixel camera feeding a powerful data processing system."It's really going to change and challenge the way people work with their data," said William O'Mullane, a project manager focused on data at Vera observatory detected over 2,100 previously unseen asteroids in 10 hours of observations, focusing on a small area of the visible sky. Its ground-based and space-based peers discover in total some 20,000 asteroids a year.O'Mullane said the observatory would allow astronomers to collect huge amounts of data quickly and make unexpected finds."Rather than the usual couple of observations and writing an (academic) paper. No, I'll give you a million galaxies. I'll give you a million stars or a billion even, because we have them: 20 billion galaxy measurements," he center is named after American astronomer Vera C. Rubin, a pioneer in finding conclusive evidence of the existence of large amounts of invisible material known as dark night, Rubin will take some 1,000 images of the southern hemisphere sky, letting it cover the entire southern sky every three or four nights. The darkest skies above the arid Atacama Desert make Chile one of the best places worldwide for astronomical observation."The number of alerts the telescope will send every night is equivalent to the inboxes of 83,000 people. It's impossible for someone to look at that one by one," said astrophysicist Francisco Foster. "We're going to have to use artificial intelligence tools."

India, Poland, Hungary make spaceflight comeback with ISS mission
25 June 2025 21:21 CAPE CANAVERAL (AFP)A US commercial mission carrying astronauts from India, Poland and Hungary blasted off to the International Space Station on Wednesday, marking the first time in decades that these nations have sent crew members to Mission 4, or Ax-4, launched from NASA's Kennedy Space Center in Florida at 2:31 am (0631 GMT), with a brand-new SpaceX Crew Dragon capsule riding atop a Falcon 9 vehicle is scheduled to dock with the orbital lab on Thursday at approximately 1100 GMT and remain there for up to 14 the spacecraft were pilot Shubhanshu Shukla of India; mission specialists Slawosz Uznanski-Wisniewski of Poland and Tibor Kapu of Hungary; and commander Peggy Whitson of the United States, a former NASA astronaut who now works for the company Axiom Space, which organises private spaceflights, among other last time India, Poland or Hungary sent people to space, their current crop of astronauts had not yet been born -- and back then, they were called cosmonauts, as they all flew on Soviet missions before the fall of the Iron became the first Indian in space since Rakesh Sharma, an air force pilot who traveled to the Salyut 7 space station in 1984 as part of a Soviet-led initiative to help allied countries access space agency, ISRO, sees this flight as a key stepping stone toward its own maiden crewed mission, planned for 2027 under the Gaganyaan program, meaning "sky craft.""What a fantastic ride," Shukla said in Hindi after liftoff. "This isn't just the start of my journey to the International Space Station -- it's the beginning of India's human space program."Indian Prime Minister Narendra Modi hailed the successful launch."He carries with him the wishes, hopes and aspirations of 1.4 billion Indians. Wish him and other astronauts all the success!" he wrote on three countries are footing the bill for their astronauts. Hungary announced in 2022 it was paying $100 million for its seat, according to India and Poland have not disclosed how much they are spending."We've got this! Poland has reached for the stars," Polish Prime Minister Donald Tusk said on X, alongside a video himself watching the launch on a screen at the Copernicus Science Centre in Warsaw. "Who knows how many future Polish astronauts watched Slawosz's launch with me? Everyone was very excited and very proud," Tusk said in another post, which included a photo of him seated next to several children at the science centre.
