Astronomers have used data from NASA's Chandra X-ray Observatory to make heads and tails of a fascinating galactic system.

Astronomers have used NASA's Chandra X-ray Observatory to discover a ring of black holes or neutron stars in a galaxy 300 million light years from Earth.

These Chandra data have provided strong evidence for the existence of so-called intermediate-mass black holes (IMBHs).

Chandra data indicates that a young star has likely destroyed and consumed an infant planet.

Astronomers using Chandra found that black holes may have squelched star formation in small, yet massive galaxies known as "red nuggets".

A new study of Alpha Centauri indicates that any planets orbiting the two brightest stars are likely not being pummeled by large amounts of X-ray radiation from their host stars.

A new study using Chandra data of GW170817 indicates that the event that produced gravitational waves likely created the lowest mass black hole known.

Astronomers have discovered a special kind of neutron star for the first time outside of the Milky Way galaxy.
