A new discovery captures the cosmic moment when a galaxy cluster – among the largest structures in the universe – started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought. This result, made using NASA’s Chandra X-ray Observatory and James Webb Space Telescope, will […]
Like a recording artist who has had a long career, NASA’s Chandra X-ray Observatory 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). The CSC contains the X-ray data detected up to the end of 2020 by Chandra, the world’s […]
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. Kepler’s Supernova Remnant, named after the German astronomer Johannes Kepler, was first spotted in the night sky in 1604. Today, astronomers know that a white dwarf star exploded when […]
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. Astronomers discovered this galaxy cluster Dec. 31, 2020. The date, combined with the bubble-like appearance of the galaxies and the superheated gas seen with Chandra observations (represented in purple), inspired the […]
