Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. This mega-explosion may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling "beads on a string."

The supermassive black hole in the center of the Milky Way is spinning so quickly it is warping the spacetime surrounding it into a shape that looks like an American football.

For the first time scientists have combined the powers of NASA's Chandra & Webb Space Telescopes to study the famous supernova remnant Cassiopeia A, helping to solve the mystery behind the remnant's "Green Monster".

These four images represent a sample of galaxy clusters that are part of the largest and most complete study to learn what triggers stars to form in the universe's biggest galaxies.

A group of dead stars known as "spider pulsars" are obliterating companion stars within their reach.

Astronomers found the most distant black hole ever detected in X-rays using the Chandra and Webb telescopes.

Chandra's data of MSH 15-52 have been combined with data from NASA's newest X-ray telescope, IXPE to unveil the magnetic field "bones" of this remarkable structure.

Using snapshots taken over 20 years with NASA's Chandra X-ray Observatory, astronomers have learned important new details about an eruption from Eta Carinae witnessed on Earth in the mid-19th century.

A new collection of stunning images highlights data from NASA's Chandra X-ray Observatory and other telescopes.

Astronomers using NASA's Chandra, ESA's XMM-Newton, and other telescopes have determined that a giant black hole has destroyed a large star and strewn its contents into space.

Astronomers have discovered the most distant galaxy cluster with an important quality — providing insight into how these gigantic structures formed and why the universe looks like it does in the present day.

Three new 'sonifications' of NASA data have been released: R Aquarii, Stephan’s Quintet, and M10.

The NGC 4839 group of galaxies is plunging into the Coma galaxy cluster and leaving behind an extraordinary tail of superheated gas.

Four composite images deliver dazzling views from NASA's Chandra X-ray Observatory and James Webb Space Telescope of two galaxies, a nebula, and a star cluster.

With a single letter seemingly etched in the X-ray glow around it, a giant black hole at the center of a massive elliptical galaxy is making a mark on its surroundings.

Astronomers have identified a new threat to life on planets like Earth: a phase during which intense X-rays from exploded stars can affect planets over 100 light-years away.

Data from Chandra show the effects of powerful winds launched from the center of a nearby galaxy.

A distant – and lonely – galaxy appears to have pulled in and assimilated all of its former companion galaxies.

A new study using NASA's Chandra X-ray Observatory has tracked two pairs of supermassive black holes in dwarf galaxies on collision courses.

Astronomers have captured a spectacular, ongoing collision between at least three galaxy clusters. Data from Chandra, XMM-Newton, and a trio of radio telescopes are helping astronomers sort out what is happening in this jumbled scene.

A new survey using NASA's Chandra X-ray Observatory has uncovered hundreds of previously "hidden" black holes.

A new study provides insight into how X-rays from stars like our Sun, but billions of years younger, could partially or completely evaporate the atmospheres of planets orbiting them.

A study of RCW 36 shows that stars in a cluster can limit how many new stars form when the biggest and brightest members expel most of the gas from the system, thus drastically slowing down star birth.

Planets can force their host stars to act younger than their age, according to a new study of multiple systems using NASA's Chandra X-ray Observatory.
