Using NASA's Chandra X-ray space telescope, astronomers have discovered an entire galaxy cluster wrapped in a 20 million light-year-wide envelope of charged particles.

The mystery surrounding a strange cosmic object, or 'long-period transient,' has deepened. This object is bursting with X-rays, and astronomers describe it as unlike anything seen before.

New data from space telescopes has been transformed into cosmic soundscapes, turning the mysterious activity around black holes into a symphony of the universe.

An X-ray signal that has puzzled scientists for 45 years was the "death knell" of a planet ripped apart by a white dwarf star, data from NASA's Chandra observatory has revealed.

A mysterious flash of X-ray emission from outside the Milky Way has left astronomers puzzled.

Observations from NASA's Chandra X-ray telescope and the VLT have revealed jets blasting from supermassive black holes cause gas to cool and fall toward them in a cosmic feeding process.

NASA's Chandra and NuSTAR telescopes have teamed up to study a supermassive black hole-powered quasar that could have played a key role in ending the cosmic dark ages.

Using NASA's Chandra X-ray telescope, astronomers witnessed a massive black hole jet slam into an unknown object in space.

Whichever mission NASA selects to image the cosmos next should launch by 2032. Here are the two contenders.

The hungriest known black hole in the early universe has been found, thanks to teamwork between NASA's James Webb Space Telescope and Chandra X-ray Observatory.
