Supernova Remnant Video From NASA’s Chandra Is Decades in Making
Supernova Remnant Video From NASA’s Chandra Is Decades in Making NASA’s Chandra X-ray Observatory has released a new video showing changes in Kepler’s Supernova Remnant over more than two and a half decades, using data from observations taken in 2000, 2004, 2006, 2014, and 2025. The supernova remnant is located about 17,000 light-years from Earth […]

NASA’s Chandra Rings in New Year With Champagne Cluster
NASA’s Chandra Rings in New Year With Champagne Cluster NASA’s Chandra X-ray Observatory has released a new image of the “Champagne Cluster,” a galaxy cluster that was discovered on New Year’s Eve, 2020. The Champagne Cluster is actually two galaxy clusters merging to form an even larger cluster, with multimillion-degree gas spreading across the cluster […]

NASA’s Chandra Finds Small Galaxies May Buck the Black Hole Trend
NASA’s Chandra Finds Small Galaxies May Buck the Black Hole Trend NASA’s Chandra X-ray Observatory has found that smaller galaxies do not contain supermassive black holes nearly as often as larger galaxies, contradicting a common idea. A study of over 1,600 galaxies collected in more than two decades of Chandra data suggests that only about […]

Mapping Dark Matter
Mapping Dark Matter NASA’s James Webb Space Telescope and Chandra X-ray Observatory collaborated to visualize dark matter. The image combines data from both observatories to show galaxy clusters and their collective light emitted by stars no longer bound to individual galaxies. Researchers used the Webb telescope’s observations to carefully measure the mass of the galaxy […]

NASA’s Chandra Reveals Star’s Inner Conflict Before Explosion
NASA’s Chandra Reveals Star’s Inner Conflict Before Explosion NASA’s Chandra X-ray Observatory has revealed that a star called Cassiopeia A (Cas A) underwent a violent rearrangement of its interior just hours before it exploded as a supernova. The study found that part of an inner layer rich in silicon traveled outwards and broke into a […]

Galaxy Clusters on Course to Crash Again, NASA’s Chandra Finds
Galaxy Clusters on Course to Crash Again, NASA’s Chandra Finds Galaxy clusters PSZ2 G181.06+48.47 are on course to collide again for the second time, with NASA’s Chandra X-ray Observatory and other telescopes capturing evidence of this rare cosmic event. The galaxy cluster, located 2.8 billion light-years from Earth, has already experienced a collision about a […]

X-ray Clues Reveal Destroyed Planet
X-ray Clues Reveal Destroyed Planet In about 5 billion years, our Sun will run out of fuel and expand, possibly engulfing Earth. These end stages of a star’s life can be utterly beautiful – as is the case with this planetary nebula called the Helix Nebula. Astronomers study these objects by looking at all kinds […]
