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.

A new result from NASA's Chandra X-ray Observatory about a system of colliding galaxy clusters may help explain this shortfall.

New versions of images combining Webb infrared data with X-rays collected by Chandra underscore how the power of any of these telescopes is only enhanced when joined with others.

It is often difficult to determine the timeline of the star's demise. By studying the spectacular remains of a supernova using NASA telescopes, a team has found enough clues to help wind back the clock.

Astronomers may have witnessed a smaller galaxy colliding with a larger spiral galaxy and delivering a supermassive black hole.

Zeta Ophiuchi is a star with a complicated past, having likely been ejected from its birthplace by a powerful stellar explosion. A new look by NASA's Chandra X-ray Observatory helps tell more of the story of this runaway star.

Astronomers used NASA's Chandra X-ray Observatory to determine the spin of the black hole in H1821+643, making it the most massive one to have an accurate measurement of this fundamental property.

A young pulsar is blazing through the Milky Way at a speed of over a million miles per hour. This stellar speedster is one of the fastest objects of its kind ever seen.

A new study shows a deep connection between some of the largest, most energetic events in the Universe and much smaller, weaker ones powered by our own Sun.

As the Event Horizon Telescope was collecting data for its remarkable new image of the Milky Way's supermassive black hole, a legion of other telescopes, including Chandra, was also watching.
