The NSF-DOE Vera C. Rubin Observatory, a major new scientific facility jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy’s Office of Science, released its first imagery today at an event in Washington, D.C. The imagery shows cosmic phenomena captured at an unprecedented scale. In just over 10 hours of test observations, NSF-DOE Rubin Observatory has already captured millions of galaxies and Milky Way stars and thousands of asteroids. The imagery is a small preview of Rubin Observatory’s upcoming 10-year scientific mission to explore and understand some of the universe’s biggest mysteries.
We invite you to attend the live stream of NSF–DOE Vera C. Rubin Observatory’s First Look event, taking place on 23 June 2025 at 11:00 a.m. EDT. At this international celebration the Rubin Observatory team will unveil the observatory’s first spectacular images. The event will be live streamed via YouTube in English and Spanish. Links to the live streams will be made available on rubinobservatory.org.
In celebration of the Hubble Space Telescope’s 35 years in Earth orbit, NASA is releasing an assortment of compelling images recently taken by Hubble, stretching from the planet Mars to star-forming regions, and a neighboring galaxy.
The U.S. National Science Foundation Daniel K. Inouye Solar Telescope, the world’s most powerful solar telescope, operated by the NSF National Solar Observatory (NSO) near the summit of Maui’s Haleakalā, reached a major milestone: achieving first light with its most advanced instrument, the new Visible Tunable Filter (VTF). The solar image it produced shows early promise to the instrument’s scientific capabilities. Designed and built by the Institut für Sonnenphysik (KIS) in Freiburg, Germany, the VTF is the world’s largest imaging spectro-polarimeter, emerging as a centerpiece to the Inouye’s instrument suite.
Over the last decade, scientists have confirmed the presence of a an important type of magnetized waves called Alfvén waves in the Sun’s outer atmosphere – i.e., the corona. These waves, specific to plasma environments like those in the Sun, can transport energy from the lower atmosphere into the hot corona and solar wind.
An international team led by NSF NOIRLab astronomer Christina Williams has discovered the most distant spiral galaxy known to date. Named Zhúlóng, meaning ‘Torch Dragon’ in Chinese mythology, this ultra-massive system existed just one billion years after the Big Bang, and yet it shows a surprisingly mature structure. Zhúlóng was discovered as part of the PANORAMIC Survey conducted on the James Webb Space Telescope.
Gas and dust ejected by a dying star at the heart of NGC 1514 came into complete focus thanks to mid-infrared data from NASA’s James Webb Space Telescope. Its rings, which are only detected in infrared light, now look like “fuzzy” clumps arranged in tangled patterns, and a network of clearer holes close to the central stars shows where faster material punched through.
Using observations from the Gemini South telescope in Chile, one half of the International Gemini Observatory, partly funded by the U.S. National Science Foundation and operated by NSF NOIRLab, astronomers have constructed a 3D representation of the newly discovered near-Earth asteroid 2024 YR4. The team determined that the unusually-shaped rock is one of the largest objects in recent history that could impact the Moon, and that it likely originated from the main asteroid belt.
The ice-giant planet Uranus, which travels around the Sun tipped on its side, is a weird and mysterious world. Now, in an unprecedented study spanning two decades, researchers using NASA’s Hubble Space Telescope have uncovered new insights into the planet’s atmospheric composition and dynamics. This was possible only because of Hubble’s sharp resolution, spectral capabilities, and longevity.
For the first time, NASA’s James Webb Space Telescope has captured bright auroral activity on Neptune. Auroras occur when energetic particles, often originating from the Sun, become trapped in a planet’s magnetic field and eventually strike the upper atmosphere. The energy released during these collisions creates the signature glow.
The DESI collaboration has published a new analysis of dark energy using their first three years of collected data, which spans nearly 15 million galaxies and quasars. Combined with studies of the cosmic microwave background, supernovae, and weak lensing, the analysis hints that dark energy changes over time. Data Release 1, containing data from DESI’s survey validation and first year of observations, has now been made available for scientists and the public to explore.
