Astronomers witness apparent birth of a black hole

Space telescopes have detected a young black hole formed from a supernova, or an exploding star, 30 years ago, a team of U.S. and European astronomers reported on Monday.

Two telescopes find massive X-Ray emitter

University Park, Pa. -- Japanese and U.S. scientists say two space telescopes helped them detect an X-ray-emitting object previously hidden inside our Milky Way galaxy.

The object -- a binary system -- was revealed Wednesday when MAXI, an instrument on the Japanese Experiment Module "Kibo" on the International Space Station caught it in the act of erupting with a massive blast of X-rays, reported Friday.

Astronomers around the world were quickly alerted and NASA's Swift Observatory followed up with an urgent "target-of-opportunity" observation 9 hours later, which allowed for the location of the X-ray nova to be measured accurately.
