Observations with NASA's Chandra X-ray Observatory have provided the first X-ray evidence of a supernova shock wave breaking through a cocoon of gas surrounding the star that exploded.

Chandra Reveals Outburst From Old Black Holes

Astronomers using NASA's Chandra X-ray Observatory have found evidence for a population of old stellar black holes. The discovery provides new insight into the nature of stellar black holes, which is a class that can produce as much energy in X-rays as what a million suns could radiate at all wavelengths.

Bright Andromeda Object Caused By 'Normal' Black Hole

A spectacularly bright object recently spotted in one of the Milky Way's neighboring galaxies is the result of a "normal" stellar black hole, astronomers have found.

GREENBELT, Md., Nov. 10 /PRNewswire-USNewswire/ -- While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by.

An international team of astronomers using the European Space Agency's XMM-Newton X-ray observatory says it's discovered a new kind of black hole. The scientists, led by Sean Farrell of the University of Leicester, England, said the newly found black hole weighs more than 500 solar masses and is a missing link between lighter stellar-mass and heavier super-massive black holes. Stellar-mass black holes about 3 to 20 times as massive as the sun, and super-massive black holes several million to...
