The image from NASA's Chandra X-ray Observatory shows the first double-sided X-ray jet ever detected from a young star. A similar jet may have been launched from the young Sun and could have had a significant impact on the early solar system. picked by AutumnLotus 2 years ago

This movie shows dynamic rings, wisps and jets of matter and antimatter around the pulsar in the Crab Nebula as observed in X-ray light by Chandra (left, blue) and optical light by Hubble (right, red). picked by Neiako 3 years ago

Astronomers are baffled after finding an exotic type of star called a pulsar apparently locked in an elongated orbit around a star much like the sun -- an arrangement defying what had been known about such objects. picked by AutumnLotus 2 years ago

A new study using results from NASA's Chandra X-ray Observatory provides one of the best pieces of evidence yet that many supermassive black holes are spinning extremely rapidly. The whirling of these giant black holes drives powerful jets that pump huge amounts of energy into their environment and affects galaxy growth. picked by AutumnLotus 2 years ago

New observations from Suzaku, a joint Japanese Aerospace Exploration Agency (JAXA) and NASA X-ray observatory, have challenged scientists' conventional understanding of white dwarfs. Observers had believed white dwarfs were inert stellar corpses that slowly cool and fade away, but the new data tell a completely different story. picked by AutumnLotus 2 years ago

A pulsar is the rapidly spinning and highly magnetized core left behind when a massive star explodes. Most of the 1,800 cataloged pulsars were found through their periodic radio emissions. Astronomers believe these pulses are caused by narrow, lighthouse-like radio beams emanating from the pulsar's magnetic poles.

NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole. This is the first detection of such a high-energy apparition, and scientists think it is evidence of a huge eruption produced by the black hole. picked by AutumnLotus 6 months ago

Using data from NASA's Chandra X-ray Observatory, scientists have reported the possible detection of a binary star system that was later destroyed in a supernova explosion. The new method they used provides great future promise for finding the detailed origin of these important cosmic events. picked by AutumnLotus 2 years ago

Using NASA's Chandra X-ray Observatory, scientists spotted the jet 20,000 light-years from Earth in Circinus X-1, a system where a spinning stellar corpse known as a neutron star is orbiting a normal star several times the mass of the sun. picked by DrNothing 2 years ago

The orbiting X-ray telescopes XXM-Newton and Chandra have caught a pair of galaxy clusters merging into a giant cluster. The discovery adds to existing evidence that galaxy clusters can collide faster than previously thought. picked by AutumnLotus 2 years ago

Astronomers have shed light on the mysterious origins of the fastest spinning stars known to science - millisecond pulsars.
These are the fastest spinning class of pulsars - dense cosmic bodies that emit radio waves along their magnetic poles. picked by bingo 6 months ago
