Sentences with phrase «surrounding exploded stars»

In the new study, Charles Hailey, an astrophysicist at Columbia University, and his colleagues scrutinized the past dozen years of data gathered by the Chandra X-ray Observatory, an orbiting craft whose instruments are designed to detect high - energy radiation emitted by the immensely hot material surrounding exploded stars and near black holes.

Now, they're seeing fireworks generated as material from that explosion rams into and heats up a ring of gas surrounding the exploding star.

NASA's Chandra X-ray Observatory has detected the gas surrounding the exploded star heated to 10 million kelvins by the shock wave's passage.

Not exact matches

Taken with the orbiting Chandra Observatory, it shows the hottest, most violent objects in the galaxy: black holes gobbling down matter, gas heated to millions of degrees by dense, whirling neutron stars, and the high - energy radiation from stars that have exploded, sending out vast amounts of material that slam into surrounding gas, creating shock waves that heat the gas tremendously, generating X-rays.

A decade ago, astronomer Mark Morris of the University of California, Los Angeles (UCLA), argued that a swarm of perhaps 10,000 small black holes — the infinitely compressed cores of large stars that exploded — should surround the huge black hole.

The characteristics of the surrounding stars suggest that although the magnetar's progenitor probably reached 40 solar masses at one point, it shed its mass so quickly that when the star exploded it fell under the 20 - solar - mass limit, thereby creating a magnetar instead of a black hole — and conforming to current theory about stellar evolution.

«So if you have this radiation before that star explodes and becomes a supernova, the radiation has already caused significant damage to the gas surrounding the star's halo.»

supernova remnant The clouds of gas and debris surrounding a star that exploded long ago.

The nebula observed around W26 is very similar to the nebula surrounding SN1987A, the remnant of a star that exploded as a supernova in 1987.

The youngest stars in the galactic region surrounding around the Solar Neighborhood are associated with «subgroup B1» of the Pleiades (M 45) stellar moving group, and astronomers hypothesize that the more massive stars born in this group may have already exploded as 20 or so supernovae over the past 10 to 20 million years as the entire group of stars moved through a nearby region of the Local Bubble (Berghoefer and Breitschwerdt, 2002).
