NASA’s Chandra finds superfluid in neutron star’s core

NASA's Chandra X-ray Observatory has discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter, at the core of a neutron star. Superfluids created in laboratories on Earth exhibit remarkable properties, su...

Chandra images torrent of star formation

A new Chandra X-ray Observatory image of Messier 82, or M82, shows the result of star formation on overdrive. At a distance of only 12 million light years, M82 provides a unique cosmic laboratory for studying conditions similar to those that e...

Taking the pulse of a black hole system

Using two NASA X-ray satellites, astronomers have discovered what drives the "heartbeats" seen in the light from an unusual black hole system. These results give new insight into the ways that black holes can regulate their intake and severely...

How often do giant black holes become hyperactive?

A new study from NASA's Chandra X-ray Observatory tells scientists how often the biggest black holes have been active over the last few billion years. This discovery clarifies how supermassive black holes grow and could have implications for ho...

First compelling evidence for a black hole after recent supernova

Amsterdam, November 17th, 2010¬ -- Black holes, or the remnants of hyper-or supernova explosions, have intrigued scientists since the concept was first introduced in 1967. Astronomers have only ever been able to observe gamma-ray bursts, considered...

Chandra finds evidence for stellar cannibalism

Evidence that a star has recently engulfed a companion star or a giant planet has been found using NASA's Chandra X-ray Observatory. The likely existence of such a "cannibal" star provides new insight into how stars and the planets around them ...

Galactic super-volcano in action

A galactic "super-volcano" in the massive galaxy M87 is erupting and blasting gas outwards, as witnessed by NASA's Chandra X-ray Observatory and NSF's Very Large Array. The cosmic volcano is being driven by a giant black hole in the galaxy's ...

Black holes seeding universe with the stuff of life?

Supermassive black holes, notorious for ripping apart and swallowing stars, might also help seed interstellar space with the elements necessary for life, such as hydrogen, carbon, oxygen and iron, scientists say. Using NASA's Chandra X-ray Observatory and ESA's XMM-Newton satellite, scientists at Penn State University and the Massachusetts Institute of Technology found evidence of high-speed winds blowing away copious amounts of gas from the cores of two quasar galaxies, which are thought to be powered by black holes.

Nasa finds 'cocoon' inside the Black Widow's web

NASA's Chandra X-ray Observatory image of the mysterious "Black Widow" pulsar reveals the first direct evidence of an elongated cocoon of high-energy particles. (A pulsar is a rotating neutron star producing powerful beams of radiation that sweep like a searchlight.) This discovery shows this billion-year-old rejuvenated pulsar is an extremely efficient generator of a high-speed flow of matter and antimatter particles.

Milky Way monster stars in cosmic reality show

The longest X-ray look yet at the supermassive black hole at the Milky Way's center has given astronomers unprecedented access to its life and times. The new data from NASA's Chandra X-ray Observatory revealed that our galaxy's central black hole is a frequent bad actor, prone to numerous outbursts and occasional large explosions.
