The AGILE satellite has detected a new super gamma flare coming from a galaxy billions of light-years away, called "Crazy Diamond" because of the unpredictable variability of its emissions. This time we have an even greater flow of energy than in previous cases. "This is the most intense gamma source ever detected since having the instruments to measure such emissions," explains Marco Tavani from the INAF-IASF in Rome, scientific manager for AGILE. "To give an analogy, the energy necessary to produce such a strong emission in a few fractions of a minute is equivalent to the energy obtained in the same time by converting the mass of several planet Earths into kinetic energy." Even if we define the source as the entire object, in reality the emission is produced in its central regions as an effect of the acceleration of matter revolving in a vortex around the gigantic black hole at the centre of the galaxy. The intensity of the gamma radiation thus depends on the quantity of matter that enters the rotation, and this is why the source alternates between periods of tranquillity and periods of enormous activity. "Theoretically there could be thousands of active galaxies with black holes ...

The German Aerospace Center's (DLR) highest management body, the Senate, will be in session on 25 November 2010 in Braunschweig for its Annual General Meeting. The DLR Executive Board will report to the Senate on the activities of the past year, important decisions will be taken and the direction for the coming year will be set out. On this occasion, we interviewed Johann-Dietrich Wörner, Chairman of the DLR Executive Board.

NASA-supported researchers have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism, which lives in California's Mono Lake, substitutes arsenic for phosphorus in the backbone of its DNA.
