Having orbited Earth more than 26 000 times, the world’s largest and most complex environmental satellite ever launched has travelled a distance of more than 1 000 000 000 kilometres, nearly the equivalent of travelling to Jupiter and back.
Generating some 280 Gigabytes of data products daily, Envisat has gathered 500 Terabytes to date. The amount of data returned by Envisat’s suite of 10 instruments is providing scientists with a global picture of our environment and is helping to fulfil the initial needs of the Global Monitoring for Environment and Security (GMES) initiative until the launch of the Sentinel satellites.
Results of ongoing research projects using data from Envisat, as well as other ESA satellites, will be presented at the 2007 Envisat Symposium in Montreux, Switzerland, from 23 to 27 April. This anniversary is particularly important because it marks the end of Envisat’s nominal lifetime, as the satellite was initially only intended to stay in orbit for five years. However, given the overall excellent standing of the satellite, the ESA Member States have agreed to fund the mission operations until 2010.

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.
