GRB Conference Invites Media
This press release caught the eye of a 2012 Forum member:
Press activities have now been planned for “Gamma Ray Bursts 2010 Conference,” a meeting of over 200 astronomers, which will take place on November 1-4 in Annapolis, MD. A press briefing featuring several notable results from the meeting will be held in the morning on Wednesday, November 3, 2010, and will be available to reporters who are not in attendance as a media telecon.
It could just be that the “new data coming from the Fermi and MAXI missions, dedicated GRB chasing by Swift and continued observations by AGILE, INTEGRAL, Konus and Suzaku” will be bringing forth interesting but not 2012ish news. Or perhaps one of these sessions could have some juicy information for us?

WR 104 – Potential Space Nasty
I really like “bad astronomy” articles, but even more so when they admit they are scared. In this instance it is a binary star known as Wr 104. At a distance of 5000-8000 light years a supernova is not expected to harm us. But a Gamma Ray Burst might, especially if it is aimed straight at us!
GRBs are a special type of supernova. When a very massive star explodes, the inner core collapses, forming a black hole, while the outer layers explode outwards. Due to a complex and fierce collusion of forces in the core, two beams of raw fury can erupt out of the star, mind-numbing in their power. Composed mostly of high-energy gamma rays, they can carry more energy in them than the Sun will put out in its entire lifetime. They are so energetic we can see them clear across the Universe, and having one too close …
