Astronomers Surprised By Gigantic ‘Cold Front’ in Perseus Galaxy Cluster
Astronomers have used Chandra to study a gigantic and resilient “cold front” in the Perseus galaxy cluster. This structure spans about 2 million light years,…
Astronomers Reveal a Magnificent New Composite Image of the Crab Nebula
Next year marks the 20th anniversary of NASA’s Chandra X-ray Observatory launch into space. The Crab Nebula was one of the first objects that Chandra…
Chandra X-Ray Observatory Reveals New Clues As To How ULXs Shine So Brightly
In the 1980s, scientists started discovering a new class of extremely bright sources of X-rays in galaxies. These sources were a surprise, as they were…
Outbursts From Supermassive Black Hole Transform Exoplanets
A team of astrophysicists and planetary scientists has predicted that Neptune-like planets located near the center of the Milky Way galaxy have been transformed into…
Chandra Shows Supermassive Black Holes Are Outgrowing Their Galaxies
The biggest black holes in the Universe are growing faster than the rate of stars being formed in their galaxies, according to two new studies…
Chandra Identifies X-Ray Emission from the Nuclear Region of Arp 220
The galaxy Arp 220 is ultraluminous (defined as having more than about 300 times the luminosity of our own galaxy) and, at a distance of…
Chandra Reveals Supermassive Black Hole ‘Turning Off and On’
A rapidly growing black hole — known as an active galactic nuclei — has been seen turning off and then on again. This supermassive black…
New Visualization Allows Viewers to Explore the Center of the Milky Way
A new visualization provides an exceptional virtual trip — complete with a 360-degree view — to the center of our home galaxy, the Milky Way….

An innovative interpretation of X-ray data from a cluster of galaxies could help scientists fulfill a quest they have been on for decades: determining the…
Chandra Reveals the Location of Elements in the Remains of Cas A
A new Chandra image shows the location of several elements produced by the explosion of a massive star. Supernova remnants and the elements they produce…
Supermassive Black Holes ‘Photobomb’ the Andromeda Galaxy
Using data from NASA’s Chandra X-ray Observatory and ground-based optical telescopes, an intriguing source has been discovered in the nearby Andromeda galaxy. Previously thought to…
VLA and Chandra Reveal the Shocking Results of Galaxy Cluster Collisions
Observations from the Very Large Array (VLA) and the Chandra X-ray observatory reveal a giant collision of several galaxy clusters, each containing hundreds of galaxies….
Astronomers View Jupiter’s Independently Pulsating X-ray Auroras
New X-ray observations show the auroras on Jupiter behave differently at each pole, making Jupiter puzzling and unlike Saturn (no known auroras) or Earth (where…
New Research Shows Jupiter’s X-Ray Auroras Pulse Independently
Using ESA’s XMM-Newton and NASA’s Chandra X-ray observatories, astronomers reveal that Jupiter’s intense northern and southern lights pulse independently of each other. The study, published…
Scientists Find Five New Pairs of Merging Supermassive Black Holes
By combining data from different telescopes, astronomers have discovered five new pairs of merging supermassive black holes. Astronomers have identified a bumper crop of dual…
