Europe is sending its first home-built receiver to the largest radio telescope array ever constructed, nestled in its permanent home in Chile, BBC News reported. The Atacama Large Millimeter Array (Alma) is made up of sixty six 39-foot wide antenna dishes that detect the faint signals in the sub-millimeter wavelength range to learn more about the formation of stars and galaxies. Scientists at the Rutherford Appleton Laboratory (RAL) in Oxfordshire will assemble and test 26 of the receivers...

CHARLOTTESVILLE, Va., Feb. 6 /PRNewswire/ -- Astronomers celebrated today the formal acceptance of the first North American antenna by the Joint ALMA Observatory. ALMA, the Atacama Large Millimeter/submillimeter Array, is a gathering armada of short-wavelength radio telescopes whose combined power will enable astronomers to probe with unprecedented sharpness phenomena and regions that are beyond the reach of visible-light telescopes. The observatory is being assembled high in the Chilean...

Nanotechnologist Chris Lodewijk has succeeded in significantly increasing the sensitivity of the new supertelescopes in Chile. He will receive his PhD on this topic at Delft University of Technology on Monday 2 February.In Chile's Atacama desert, technicians and astronomers from around the world are currently working on the Atacama Large Millimeter Array (ALMA). This consists of 66 advanced telescopes which will be placed at an altitude of 5,000 metres and together will provide a more precise...

Astronomers have a new insight into the active galaxy Centaurus A (NGC 5128), as the jets and lobes emanating from the central black hole have been imaged at submillimeter wavelengths for the first time. The new data, from the Atacama Pathfinder Experiment (APEX) telescope in Chile, which is operated by ESO, have been combined with visible and X-ray wavelengths to produce this striking new image. Centaurus A is our nearest giant galaxy, at a distance of about 13 million light-years in the...

Black holes may have come before the formation of galaxies, astronomers reported on Wednesday, adding information that could provide new insights into the nature of the mysterious invisible black objects. At the  213th meeting of the American Astronomical Society in Long Beach, California, researchers said they discovered a clear link between the mass of a black hole and the galaxy where it was spotted. "It looks like the black holes came first. The evidence is piling up," said Chris...

High in the Atacama region in northern Chile, one of the world's most advanced telescopes has just passed a major milestone. The first of many state-of-the-art antennas has just been handed over to the Atacama Large Millimeter/submillimeter Array (ALMA) project. ALMA is under construction on the plateau of Chajnantor, at an altitude of 5000 m. The telescope is being built by a global partnership, including ESO as the European partner. ALMA will initially comprise 66 high precision antennas,...

Illustrating the power of submillimeter-wavelength astronomy, an APEX image reveals how an expanding bubble of ionized gas about ten light-years across is causing the surrounding material to collapse into dense clumps that are the birthplaces of new stars. Submillimeter light is the key to revealing some of the coldest material in the Universe, such as these cold, dense clouds. The region, called RCW120, is about 4200 light years from Earth, towards the constellation of Scorpius. A hot,...

In the thin, dry air of northern Chile's Atacama Desert, at an altitude of 16,500 feet, an amazing new telescope system is taking shape, on schedule to provide the world's astronomers with unprecedented views of the origins of stars, galaxies, and planets. The Atacama Large Millimeter/submillimeter Array (ALMA) will open an entirely new "window" on the Universe, allowing scientists to unravel longstanding and important astronomical mysteries. "Most of the photons in the Universe are in the...
