| Astronomers create first realistic virtual universe Posted: 07 May 2014 11:28 AM PDT Move over, Matrix - astronomers have done you one better. They have created the first realistic virtual universe using a computer simulation called 'Illustris.' Illustris can recreate 13 billion years of cosmic evolution in a cube 350 million light-years on a side with unprecedented resolution. |
| A stellar explosion on the outer reaches of the Universe provides clues about black hole formation Posted: 07 May 2014 08:47 AM PDT On 24 October 2012 observatories across the world were alerted about a huge stellar explosion, the GRB121024A, which had been located just hours before in the Eridanus constellation. The data obtained on that explosion, which took place about 11,000 million years ago, have made it possible to reconstruct how a black hole is formed. |
| Posted: 07 May 2014 06:30 AM PDT Astronomers have discovered a "hypervelocity star" that is the closest, second-brightest and among the largest of 20 found so far. Speeding at more than 1 million mph, the star may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious "dark matter" surrounding the galaxy, astronomers say. |
