Before the end of January particles from a distant comet will be delivered to The Open University and research will begin on what could be keys to the origin of life in the universe.
NASA’s Stardust mission is returning to Earth early January 15th after a three billion-mile (4.6 billion-km) trip to collect interstellar comet dust from Comet Wild 2 (pronounced vilt after the Swiss man who discovered it). During a brief encounter with Comet Wild 2 nearly two years ago, Stardust captured thousands of particles as it came within 146 miles (240 km) of the comet, surviving the high speed impact of millions of dust particles and small rocks up to nearly half a centimetre across. Stardust’s tennis racket shaped collector captured thousands of these comet particles into cells filled with Aerogel-- a substance so light it almost floats in air.
The samples are returning to Earth in a capsule that will parachute into the Utah desert, the first sample-return mission to a comet. The first samples will be made available to a small number of teams, including The Open University’s Planetary and Space Science Research Institute (PSSRI), for preliminary analysis before their release to the wider scientific community.
Professor Keith Mason, Chief Executive Officer of the Particle Physics and Astronomy Research Council (PPARC), which part funded the UK involvement in Stardust, said, “The return of the samples from Stardust is a truly remarkable feat. It will be the first time in the history of space exploration that samples from a comet will be returned to Earth. It is particularly exciting that the Open University team will be one of the first to analyse the samples – helping to further our understanding of the origins of the Solar System.”

Gravitational wave kicks monster black hole out of galactic core

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
