Radical Antarctic telescope "would outdo Hubble"

16.09.2004


A novel Antarctic telescope with 16-m diameter mirrors would far outperform the Hubble Space Telescope, and could be built at a tiny fraction of its cost, says a scientist from the Anglo-Australian Observatory in Sydney, Australia.

Tests by a team from the University of New South Wales, reported in the journal ‘Nature’ this week [16 September], show that the ‘Dome C’ site in the Australian Antarctic Territory is by far the best place ever tested on Earth for doing infrared and optical astronomy. “A telescope there would perform as well as a much larger one anywhere else on Earth. It’s nearly as good as being in space”, said Dr. Will Saunders of the Anglo-Australian Observatory.

At the SPIE Astronomical Telescopes and Instrumentation conference in Glasgow in June, Dr. Saunders presented a concept for an unusual telescope that’s well matched to the special conditions at Dome C, both in its optical design and in the way it’s built.



It looks nothing like other telescopes. Much of it could be built of ‘icecrete’–snow compressed to form blocks as hard as concrete–while its mirrors could be made of the glass used for office windows. Under the superb atmospheric conditions at Dome C this simple telescope could make razor-sharp images of large areas of sky.

Dr. Saunders estimates that his design would cost about a fifth as much as one of the extremely large telescopes now being planned. These have mirrors 30-100 m in diameter and price tags of US$700 million and up. The Hubble Space Telescope cost a few times more: about US$2.2 billion at launch.

“With this simple telescope you could do the exquisite imaging that the extremely large telescopes plan to do, at a fraction of their cost” Dr. Saunders said. “But, unlike them, this telescope would also be a great survey instrument, able to map the whole sky with Hubble-like clarity.”

Im Focus: Giant Magnetic Fields in the Universe

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...

Im Focus: Tracing down linear ubiquitination

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...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

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.
