Ultraluminous Gamma Ray Burst 080607 – A "Monster in the Dark" |
Shedding Light on Dark Gamma Ray Bursts
Gamma Ray Bursts (GRBs) are among the most energetic phenomena astronomers regularly observe. These events are triggered by massive explosions and a large amount of the energy if focused into narrow beams that sweep across the universe. These beams are so tightly concentrated that they can be seen across the visible universe and allow astronomers to probe the universe's history. If such an event happened in our galaxy and we stood in the path of the beam, the effects would be pronounced and may lead to large extinctions. Yet one of the most energetic GRBs on record (GRB 080607) was shrouded in cloud of gas and dust dimming the blast by a factor of 20 – 200, depending on the wavelength. Despite this strong veil, the GRB was still bright enough to be detected by small optical telescopes for over an hour. So what can this hidden monster tell astronomers about ancient galaxies and GRBs in general?(...) Read the rest of Ultraluminous Gamma Ray Burst 080607 – A "Monster in the Dark" | | | | |

PASADENA, Calif. -- NASA has begun development of a mission to visit and study the sun closer than ever before. The unprecedented project, named Solar Probe Plus, is slated to launch no later than 2018.
The small car-sized spacecraft will plunge directly into the sun's atmosphere approximately 6.4 million kilometers (four million miles) from our star's surface. It will explore a region no other spacecraft ever has encountered. NASA has selected five science investigations that will unlock the sun's biggest mysteries, including one led by a scientist from NASA's Jet Propulsion Laboratory, Pasadena, Calif.

GOOGLE LUNAR X PRIZE SUMMIT TO BE HELD ON THE ISLE OF MAN |
ISLE OF MAN – 30 August, 2010 – The Isle of Man Government (www.spaceisle.com) and the X PRIZE Foundation (www.xprize.org) are pleased to announce the fourth Google Lunar X PRIZE Team Summit will be hosted on the Isle of Man on October 4-5, 2010 during the United Nations declared World Space Week. Senior executives from many of the twenty-two teams competing for the Google Lunar X PRIZE will come together to interact directly with representatives from Google and the X PRIZE Foundation, industry experts and Space Isle representatives from the Isle of Man. Each of these teams is striving to claim a share of the US $30 million prize purse money by becoming the first privately funded team to send a robot to the Moon that can travel 500 meters and transmit video, images and data back to the Earth.

MARS EXPRESS: Rätselhafte Struktur zwischen Marsvulkanen |
Ein neues, jetzt vom Deutschen Zentrum für Luft- und Raumfahrt veröffentlichtes Bild der europäischen Marssonde Mars Express zeigt mit Orcus Patera eine rätselhafte Struktur, die zwischen den gewaltigen Marsvulkanen Olympus Mons und Elysium Mons liegt. Ihre Entstehung ist bislang nicht geklärt, es gibt aber mehrere Theorien.
