Chandra and Webb combine to solve the mystery of the “Green Monster”
Astronomers have, for the first time, combined data from NASA’s Chandra X-ray Observatory and the James Webb Space Telescope to study the well-known supernova remnant Cassiopeia A (Cas A). This collaborative effort has shed light on an unusual structure in the debris known as the “Green Monster,” first discovered in Webb data in April 2023.
Chandra investigates an X-ray mystery from epic kilonova
For the first time, astronomers are studying the aftermath of a kilonova — an epic burst of energy that occurs when two neutron stars collide and merge. NASA has used it Chandra X-ray Observatory to observe the kilonova GW170817, and the observations have raised some unexpected questions. Neutron stars are some of the densest objects…
NASA’s Chandra X-ray Observatory suffers camera glitch, stalling science

(Image credit: NASA) A prolific NASA space telescope has closed its camera eye for now due to a power issue that has stalled the observatory's science work.The Chandra X-ray Observatory, which has…
Chandra Detects Mini-Supermassive Black Hole in Star-Forming Dwarf Galaxy
A supermassive black hole with 200,000 solar masses is located in the middle of the dwarf galaxy Markarian 462 (Mrk 462), according to new research led by Dartmouth College astrophysicists. This graphic shows X-rays that NASA’s Chandra X-ray Observatory detected from the dwarf galaxy Mrk 462. This X-ray emission (inset) is important because it reveals…
Chandra Spots Four Cavities in Center of Galaxy Cluster
Astronomers using NASA’s Chandra X-ray Observatory have found a quartet of pronounced X-ray cavities in RBS 797, a cluster of galaxies located about 3.9 billion light-years away in the constellation of Draco. This suggests there is a pair of closely orbiting supermassive black holes, both of which erupted and generated jets at about the same…
