The Crab Nebula has stunned astronomers by emitting an unprecedented blast of gamma rays, the highest-energy light in the Universe, from a small area of the famous nebula. The cause of the 12 April gamma-ray flare, which lasted for some six days, hitting levels 30 times higher than normal and varying at times from hour [...]
Is our universe infinite or closed? Because the visible Universe is expanding, the most distant visible things are much further away than its estimated 14-billion year age. In fact, the photons in the cosmic microwave background have traveled a cool 45 billion light years to get here. That makes the visible universe some 90 billion [...]

The accomplished astrophotographer Anthony Wesley got pictures of it, and I wondered to myself when Cassini would snap some shots. Turns out, I didn’t have to wait long! The spacecraft took images of the planet on December 24th, [...]
Space rock surprise, Amino acids in meteorite may have unexpected origin By Ron Cowen, sciencenews.org This meteorite fragment of asteroid 2008 TC3 is one of about 600 recovered from Sudan’s Nubian desert. Amino acids found in one fragment suggest that these fragile building blocks of life may be able to form without liquid water and [...]

A UK-led international team of astronomers have presented the first conclusive evidence for a dramatic surge in star birth in a newly discovered population of massive galaxies in the early Universe. Their measurements confirm the idea that stars formed most rapidly about 11 billion years ago, or about three billion years after the Big Bang, [...]
