Bubbles with Titanium Trigger Titanic Explosions

April 21st 2021 at 10:38
Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA’s Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode.

Sometimes Black Holes Are Prettier in Pink

April 14th 2021 at 08:28
This image, taken by the Chandra X-Ray Observatory in 2012, shows an extraordinary outburst from a black hole.

First X-rays from Uranus Discovered

March 31st 2021 at 11:00
​Astronomers have detected X-rays from Uranus for the first time, using NASA’s Chandra X-ray Observatory. This result may help scientists learn more about this enigmatic ice giant planet in our solar system.

Gigantic Jet Spied from Black Hole in Early Universe

March 9th 2021 at 09:44
Astronomers have discovered evidence for an extraordinarily long jet of particles coming from a supermassive black hole in the early universe, using NASA’s Chandra X-ray Observatory.

Reclusive Neutron Star May Have Been Found in Famous Supernova

February 22nd 2021 at 19:01
Astronomers now have evidence from two X-ray telescopes (Chandra and NuSTAR) for a key component of a famous supernova remnant. This latest study shows that a "pulsar wind nebula" created by such a neutron star may be present.

Rare Blast’s Remains Discovered in Milky Way Center

February 8th 2021 at 10:41
Astronomers may have found our galaxy’s first example of an unusual kind of stellar explosion. This discovery, made with NASA’s Chandra X-ray Observatory, adds to the understanding of how some stars shatter and seed the universe with elements critical for life on Earth.

Galaxies Hit Single, Doubles, and a Triple (Growing Black Holes)

January 14th 2021 at 11:59
When three galaxies collide, what happens to the huge black holes at the centers of each? A new study using NASA’s Chandra X-ray Observatory and several other telescopes reveals new information about how many black holes are furiously growing after these galactic smash ups.

Chandra Studies Extraordinary Magnetar

January 8th 2021 at 09:00
In 2020, astronomers added a new member to an exclusive family of exotic objects with the discovery of a magnetar. New observations from NASA’s Chandra X-ray Observatory help support the idea that it is also a pulsar, meaning it emits regular pulses of light.

On the Hunt for a Missing Giant Black Hole

December 17th 2020 at 10:09
Astronomers are searching for signs of a supermassive black hole in the galaxy cluster Abell 2261. Scientists think this galaxy underwent a merger with another galaxy, which could have caused a newly formed larger black hole to be ejected. Astronomers do not yet know what happened to this giant black hole.
