Many of those challenges are purely scientific, including the quest to clarify the true nature of dark matter and dark energy; the search for extra-terrestrial life among the myriad of extrasolar planets that are set to be discovered; and finding the first stars that formed after the Big Bang.
Other challenges are political - including the need for mass international collaboration to fund and manage astronomical facilities, many of which are being so large and expensive that no single country can afford them alone. For example, the Atacama Large Millimeter Array, which is being built in Chile, involves astronomers from the UK, US and Japan.
The contributors are Catherine Cesarsky, President of the International Astronomical Union, Martin Rees, the UK's Astronomer Royal, Tim de Zeeuw, Director General of the European Southern Observatory, John Huchra, President of the American Astronomical Society, Andrew Fabian, President of the Royal Astronomical Society, and Seok Jae Park, President of the Korea Astronomy and Space Science Institute.
All contributors express optimism about the future of global astronomy, reflecting on the advances that new facilities promise: from the Planck Satellite making detailed observation of fossil radiation, due to take off next month; NASA's planned joint dark energy mission; 2013's launch of the James Webb Space Telescope to help answer questions about the Universe's very first stars; and the European Southern Observatory's European Extremely Large Telescope, which, if built, could be the "world's biggest eye on the sky".
As Tim de Zeeuw, Director of the European Southern Observatory, writes, "Technological developments now make it possible to observe planets orbiting other stars, peer deeper than ever into the universe, use particles and gravitational waves to study celestial sources, and to carry out in situ exploration of objects in our solar system. This promises tremendous progress towards answering key astronomical questions."
But, as Seok Jae Park, President of the Korea Astronomy and Space Science Institute, says, "The greatest challenge for astronomy is international collaboration, because building big and expensive telescopes can no longer be accomplished by a single country alone. It is my hope that IYA2009 will enable astronomers from around the world to create a new tradition of cooperation in astronomy."
Catherine Cesarsky, President of the International Astronomical Union, underlines her wish during IYA2009 to communicate the joys and benefits of astronomy. "It is [the] sense of discovery and awe that astronomers wish to share with our fellow citizens all over the world. We thus hope to stimulate a long-term increase in student enrolment in science and technology, and an appreciation for lifelong learning."

Space observation with radar to secure Germany's space infrastructure

Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no.
