| Astronomers see right into heart of exploding star Posted: 08 Oct 2014 11:11 AM PDT Astronomers have been able to see into the heart of an exploding star, by combining data from telescopes that are hundreds or even thousands of kilometers apart. |
| Posted: 08 Oct 2014 10:34 AM PDT Astronomers working with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) have found a pulsating dead star beaming with the energy of about 10 million suns. The object, previously thought to be a black hole because it is so powerful, is in fact a pulsar -- the incredibly dense rotating remains of a star. |
| Hungry black hole eats faster than thought possible Posted: 08 Oct 2014 10:13 AM PDT Astronomers have discovered a black hole that is consuming gas from a nearby star 10 times faster than previously thought possible. The black hole -- known as P13 -- lies on the outskirts of the galaxy NGC7793 about 12 million light years from Earth and is ingesting a weight equivalent to 100 billion billion hot dogs every minute. |
