The team behind the long-awaited Vera Rubin Observatory in Chile yesterday published their first images, revealing breathtaking views of star-forming regions as well as distant galaxies.
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 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 new image reveals these stellar nurseries within the 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,” White House Office of Science and Technology Policy Director Michael Kratsios said.
Equipped with an advanced 8.4m telescope and the largest digital camera ever built, the observatory is supported by a powerful data-processing system.
Later this year it is to begin its flagship project, the Legacy Survey of Space and Time. Over the next decade, it will scan the night sky nightly, capturing even the subtlest visible changes with unmatched precision.
The observatory is named after pioneering US astronomer Vera 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 US National Science Foundation and the US 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 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.
The observatory is also set to be the most effective at spotting interstellar objects passing through the solar system.
MONEY GRAB: People were rushing to collect bills scattered on the ground after the plane transporting money crashed, which an official said hindered rescue efforts A cargo plane carrying money on Friday crashed near Bolivia’s capital, damaging about a dozen vehicles on highway, scattering bills on the ground and leaving at least 15 people dead and others injured, an official said. Bolivian Minister of Defense Marcelo Salinas said the Hercules C-130 plane was transporting newly printed Bolivian currency when it “landed and veered off the runway” at an airport in El Alto, a city adjacent to La Paz, before ending up in a nearby field. Firefighters managed to put out the flames that engulfed the aircraft. Fire chief Pavel Tovar said at least 15 people died, but
LIKE FATHER, LIKE DAUGHTER: By showing Ju-ae’s ability to handle a weapon, the photos ‘suggest she is indeed receiving training as a successor,’ an academic said North Korea on Saturday released a rare image of leader Kim Jong-un’s teenage daughter firing a rifle at a shooting range, adding to speculation that she is being groomed as his successor. Kim’s daughter, Ju-ae, has long been seen as the next in line to rule the secretive, nuclear-armed state, and took part in a string of recent high-profile outings, including last week’s military parade marking the closing stages of North Korea’s key party congress. Pyongyang’s official Korean Central News Agency (KCNA) released a photo of Ju-ae shooting a rifle at an outdoor shooting range, peering through a rifle scope
South Korea would soon no longer be one of the few countries where Google Maps does not work properly, after its security-conscious government reversed a two-decade stance to approve the export of high-precision map data to overseas servers. The approval was made “on the condition that strict security requirements are met,” the South Korean Ministry of Land, Infrastructure and Transport said. Those conditions include blurring military and other sensitive security-related facilities, as well as restricting longitude and latitude coordinates for South Korean territory on products such as Google Maps and Google Earth, it said. The decision is expected to hurt Naver and Kakao
India and Canada yesterday reached a string of agreements, including on critical mineral cooperation and a “landmark” uranium supply deal for nuclear power, the countries’ leaders said in New Delhi. The pacts, which also covered technology and promoting the use of renewable energy, were announced after Indian Prime Minister Narendra Modi and Canadian Prime Minister Mark Carney hailed a fresh start in the relationship between their nations. “Our ties have seen a new energy, mutual trust and positivity,” Modi said. Carney’s visit is a key step forward in ties that effectively collapsed in 2023 after Ottawa accused New Delhi
