The investigation could solve the mystery of how supermassive black holes grew so large in the early universe.

A novel "X-arithmetic" technique reveals how black holes shape the universe's largest structures.

The Hubble Telescope and Chandra X-ray Observatory saw an enigmatic intermediate-mass black hole lighting up in X-rays, potentially revealing a way of finding more of them in the future.

Astronomers have used the Chandra X-ray telescope to observe an exoplanet as it disintegrates because its parent star is bombarding it with radiation.

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.
