Odyssee nach Zagreb

Heute haben wir die EU verlassen. Sogleich wird einem klar, was die offenen Grenzen gebracht haben. Der Zug stand geschlagene 1 1/2 Stunden in der prallen Sonne rum und wurde erst von ungarischen und dann von kroatischen Sicherheitsbeamten gefilzt. Was für eine Prozedur.

A Supernova Cocoon Breakthrough

Observations with NASA's Chandra X-ray Observatory have provided the first X-ray evidence of a supernova shock wave breaking through a cocoon of gas surrounding the star that exploded. This discovery may help astronomers understand why some supernovas are much more powerful than others. On Nov. 3, 2010, a supernova was discovered in the galaxy UGC 5189A, located about 160 million light years away. Using data from the All Sky Automated Survey telescope in Hawaii taken earlier, astronomers determined this supernova exploded in early October 2010 (in Earth's time-frame). This composite image of UGC 5189A shows X-ray data from Chandra in purple and optical data from Hubble Space Telescope in red, green and blue. SN 2010jl is the very bright X-ray source near the top of the galaxy. A team of researchers used Chandra to observe this supernova in December 2010 and again in October 2011. The supernova was one of the most luminous that has ever been detected in X-rays. The results of these observations were published in a paper that appeared in the May 1, 2012 issue of The Astrophysical Journal Letters.
