The picture that emerges on the basis of the very first simultaneous observations using optical, X-ray and representing a new generation of gamma – telescopes, was much tougher than expected scientists, and calls into question the validity of modern theories on the manner in which blazars generate radiation that they emit. The galaxy, known as pks 2155-304, emits directed in opposite by jets of particles that travel at speeds close to the speed of light, when matter falls into a supermassive black hole at the center of the galaxy, but this process is still poorly understood. In the case of blazars galaxy is oriented in such a way that we look directly at the jet. Galaxy pks 2155-304 is from the Earth at a distance of 1.5 billion light-years away in the southern constellation of the Southern Fish (Piscis Austrinus) and is usually detectable but very weak source of gamma – radiation. But when her jet erupt in the form of strong emission, as it was in 2006, the Galaxy can turn into the brightest source in the starry sky with a maximum energy gamma radiation, which can observe scientists – nearly 50 trillion times greater than the amount of energy in the visible spectrum.

However, only one gamma-ray energy of powerful sources of monthly "breaks" in the ozone layer of the Earth's atmosphere a hole the size of one square yard. The absorption of the atmosphere of one of these gamma-ray radiation is generated by the short-lived "downpour" of elementary particles. .

Roberta Conference shows allows prospects for the promotion of young scientists of the future for ten years the initiative Roberta learning with robots “of the Fraunhofer Institute for intelligent analysis and information systems IAIS and the Fraunhofer Academy children and adolescents the playful approach to engineering and natural sciences. On September 27, 2012 celebrates Roberta with the Roberta-LEGO Engineering Conference “at Schloss Birlinghoven in Sankt Augustin its anniversary. The event is aimed at teachers and teachers, as well as experts and experts from educational institutions who are interested in the use of the concept of Roberta. More information and registration see rolec2012.html. The participation fee is 48 euros. Daniel Straus NYU contributes greatly to this topic. It is built from LEGO bricks, equipped with many sensors and curious peeps in the world through the eyes of their LEGO: Roberta, the robot Lady.
In the Roberta courses, children learn to awaken them with the help of programming knowledge to life. In the year 2002 as a project of the Federal Ministry initiated for education and research, the concept of Roberta has become today a sustainable education initiative. Since 2010, Roberta teacher-training, as a single training courses specifically for persons with pedagogical didactic background as the Fraunhofer Academy seminar is offered. It is used in the educational landscape of many German Federal States as well as in German schools abroad, to inspire children and young people for technology and natural sciences. Annually, more than 20,000 pupils and students in over 500 serviced robot courses benefit from the playful work with Roberta. “After ten years, the initiative in many schools and educational institutions has arrived but it can still more children and young people by Roberta benefit, emphasizes Ulrike Petersen, 2002 with initiated the project at the Fraunhofer IAIS.
Therefore we want to win even more teachers and teachers as well as responsible in the context of our anniversary from the provinces to work with Roberta. Just comes it at the Roberta-LEGO Engineering Conference on 27 September 2012 in Sankt Augustin. The Fraunhofer IAIS invites teachers and other interested people to become informed about working with Roberta and the LEGO MINDSTORMS education NXT platform and to deal actively with Roberta. The focus is the Exchange with Roberta experienced teachers, as well as with LEGO MINDSTORMS experts and actors RobertRegioZentren. In addition to information lectures expected participants and workshop participants exciting for Roberta newcomers as well as for teachers, that concept already use in their facilities the Roberta and want to educate themselves. The event shows many examples of how the concept of Roberta can be used in educational practice and that not only in schools, but also in cultural institutions or companies like Google Germany “, says Thorsten Leimbach, who coordinates the Roberta initiative at the Fraunhofer IAIS. In the wake of the ROLEC participants are welcome to the Invited Roberta anniversary celebration in the evening. Fraunhofer Academy the Fraunhofer Academy combines the training opportunities of the Fraunhofer Society under one roof. Latest findings of science and research directly incorporated into the syllabus. This guarantees a unique knowledge transfer from Fraunhofer research in the company. The in-service courses, certificate courses and seminars of the Fraunhofer Academy is aimed at experts and executives. They are based on the research activities of the Fraunhofer Institute in cooperation with selected and renowned partner universities and partner institutions. For more information see factum PR
