Astronomers using data from NASA’s Chandra X-ray Observatory have determined that a massive group of galaxies called Abell 1033 is actually two galaxy...
Astronomers using NASA’s Chandra X-ray Observatory have confirmed that a supernova remnant called Kes 75 contains the youngest known pulsar in our Milky...
A distant relative to GW170817, the first source identified to emit gravitational waves and light, has been discovered. Reported in the journal Nature...
For decades, astronomers have puzzled over the variability of young stars residing in Taurus-Auriga dark clouds, a group of molecular clouds located in...
New observations by NASA’s Chandra X-ray Observatory indicate the two brightest stars in the triple-star system Alpha Centauri are not pummeling any...
When two galaxies collide, their central supermassive black holes also smash together. But before they do, these galaxies often flicker on, absorbing huge...
A new study using X-ray data from NASA’s Chandra X-ray Observatory indicates that the neutron star merger that became the gravitational wave source,...
First discovered by Italian mathematician and priest Giovanni Battista Hodierna in 1654, NGC 6231 is a young star cluster located in the constellation...
Astronomers using NASA’s Chandra X-ray Observatory have discovered what they believe are 12 stellar-mass black holes gathered around Sagittarius A*,...
Using NASA’s Chandra X-ray Observatory, astronomers have found evidence for what is likely the most massive black holes ever detected.
A massive black...
Using X-ray data from NASA’s Chandra X-ray Observatory and optical data from ground-based telescopes, astronomers have spotted what could be the most...
For the first time, astronomers have observed the source of gravitational waves, created by the merger of two neutron stars. The cataclysmic aftermaths...
Five new pairs of merging supermassive black holes have been discovered by combining data from NASA’s Chandra X-ray Observatory, the Wide-Field Infrared...
X-rays emitted by a Sun-like star may provide valuable information about whether its planetary system will be hospitable to life, a new study suggests....
Astronomers have detected the first X-rays from a Type Ia supernova, located inside the spiral-shaped galaxy ESO 336-G009.
An image showing X-rays detected...
A wave spanning 200,000 light-years (about twice the size of our Milky Way Galaxy) is rolling through the Perseus Cluster, according to observations from...
