Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of…
Chandra observations indicate the two brightest stars in Alpha Centauri are not pummeling any orbiting planets with large amounts of X-rays. Alpha Centauri is a…
Astronomers have discovered a special kind of neutron star for the first time outside of the Milky Way galaxy, using data from NASA’s Chandra X-ray…
Astronomers have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy using data from NASA’s Chandra X-ray Observatory….
Perseus Cluster A gigantic and resilient “cold front” is hurtling through the Perseus galaxy cluster according to data from Chandra & other X-ray observatories. This…
Astronomers think that our Sun was born in a stellar cluster about 4.6 billion years ago that quickly dispersed. Chandra’s image of the stellar cluster…
Cataclysmic variable stars (CVs) are white dwarf stars that are accreting from an orbiting, low-mass binary companion star. The accretion is facilitated by the proximity…
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,…
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…
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…
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…
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…
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…
A rapidly growing black hole — known as an active galactic nuclei — has been seen turning off and then on again. This supermassive black…
A new visualization provides an exceptional virtual trip — complete with a 360-degree view — to the center of our home galaxy, the Milky Way….
A new project using data from NASA’s Chandra X-ray Observatory and other telescopes allows people to navigate through real data of the remains of an…
Astronomers studying the Toothbrush Cluster with new radio observations combined with other wavelengths have been able to confirm the galaxy merger scenario and estimate the…
