NASA Telescopes Spot Surprisingly Mature Cluster in Early Universe https://chandra.harvard.edu/photo/2026/protoc/ https://chandra.harvard.edu/photo/2026/protoc/ Wed, 28 Jan 2026 12:00:00 EST A new discovery captures the cosmic moment when a galaxy cluster started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought. NASA's Chandra Releases Deep Cut From Catalog of Cosmic Recordings https://chandra.harvard.edu/photo/2026/csc/ https://chandra.harvard.edu/photo/2026/csc/ Fri, 23 Jan 2026 12:00:00 EST Like a recording artist who has had a long career, Chandra has a "back catalog" of cosmic recordings that is impossible to replicate. To access these X-ray tracks, or observations, the ultimate compendium has been developed: the Chandra Source Catalog (CSC). Supernova Remnant Video From NASA's Chandra Is Decades in Making https://chandra.harvard.edu/photo/2026/kepler/ https://chandra.harvard.edu/photo/2026/kepler/ Tue, 06 Jan 2026 12:00:00 EST A new video shows the evolution of Kepler's Supernova Remnant using data from NASA's Chandra X-ray Observatory captured over more than two and a half decades. NASA's Chandra Rings in New Year With Champagne Cluster https://chandra.harvard.edu/photo/2025/champagne/ https://chandra.harvard.edu/photo/2025/champagne/ Tue, 30 Dec 2025 12:00:00 EST Celebrate the New Year with the "Champagne Cluster," a galaxy cluster seen in this new image from NASA's Chandra X-ray Observatory and optical telescopes. Cosmic Holiday Greetings From NASA's Chandra X-ray Observatory https://chandra.harvard.edu/photo/2025/holidays/ https://chandra.harvard.edu/photo/2025/holidays/ Mon, 22 Dec 2025 12:00:00 EST Chandra is sending out a holiday card with four new images of cosmic wonders. Each of the quartet of objects evokes the winter season or one of its celebratory days, either in its name or shape. Bright Blue Cosmic Outbursts Likely Caused by Large Black Holes Shredding Massive Companions https://chandra.harvard.edu/photo/2025/fbot/ https://chandra.harvard.edu/photo/2025/fbot/ Tue, 16 Dec 2025 12:00:00 EST A luminous fast blue optical transient (LFBOT) named AT 2024wpp likely came from an extreme event where a black hole up to 100 times the mass of the Sun tore apart a companion star that got too close. NASA's Chandra Finds Small Galaxies May Buck the Black Hole Trend https://chandra.harvard.edu/photo/2025/smbhs/ https://chandra.harvard.edu/photo/2025/smbhs/ Thu, 11 Dec 2025 12:00:00 EST A new study, analyzing over 1,600 galaxies observed with Chandra over two decades, suggests that smaller galaxies do not contain supermassive black holes nearly as often as larger galaxies do. Painting Galaxy Clusters by Numbers (and Physics) https://chandra.harvard.edu/photo/2025/xa/ https://chandra.harvard.edu/photo/2025/xa/ Tue, 09 Dec 2025 12:00:00 EST A new image-processing technique called "X-arithmetic" is allowing astronomers to analyze Chandra's X-ray data and identify features in the gas of galaxy clusters and groups like never before. Before Fall Leaves, See Seasonal Offerings from NASA's Chandra https://chandra.harvard.edu/photo/2025/fall/ https://chandra.harvard.edu/photo/2025/fall/ Mon, 24 Nov 2025 12:00:00 EST Before fall gives way to winter in the northern hemisphere, NASA's Chandra X-ray Observatory has several images that celebrate autumn and its many delights to share.
