WASHINGTON, May 5 /PRNewswire-USNewswire/ -- Two missions to study the cosmos, the Herschel and Planck spacecraft, are scheduled to blast into space May 14 aboard the same Ariane 5 rocket from the Guiana Space Center in French Guiana. The European Space Agency, or ESA, leads both missions with significant participation from NASA. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO ) "The missions are quite different, but they'll hitch a ride to space together," said Ulf...

An international team of astronomers have undertaken a survey with a new submillimeter camera have discovered more than a hundred dusty galaxies in the early Universe, each of which is in the throes of an intense burst of star formation. One of these galaxies is an example of a rare class of starburst, seen just 1 billion years after the Big Bang. In her presentation on Wednesday 22nd April at the European Week of Astronomy and Space Science conference, team leader Dr. Kristen Coppin of...

Scientists from the University of Toronto and the University of British Columbia have helped unveil the birthplaces of ancient stars using a two-ton telescope carried by a balloon the size of a 33-storey building. After two years spent analyzing data from the Balloon-borne Large-Aperture Sub-millimeter Telescope (BLAST) project, an international group of astronomers and astrophysicists from Canada, the U.S. and the U.K. reveals today in the journal Nature that half of the starlight of the...

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...

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,...

Astronomers have uncovered strong evidence that brown dwarfs form like stars. Using the Smithsonian's Submillimeter Array (SMA), they detected molecules of carbon monoxide shooting outward from the object known as ISO-Oph 102. Such molecular outflows typically are seen coming from young stars or protostars. However, this object has an estimated mass of 60 Jupiters, meaning it is too small to be a star. Astronomers have classified it as a brown dwarf. Brown dwarfs are on the dividing line...

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,...

Astronomers have uncovered an extreme stellar machine -- a galaxy in the very remote universe pumping out stars at a surprising rate of up to 4,000 per year. In comparison, our own Milky Way galaxy turns out an average of just 10 stars per year. The discovery, made possible by several telescopes including NASA's Spitzer Space Telescope, goes against the most common theory of galaxy formation. According to the theory, called the Hierarchical Model, galaxies slowly bulk up their stars over...

New measurements from some of the most distant galaxies bolster the evidence that the strongest burst of star formation in the history of the Universe occurred about two billion years after the Big Bang. An international team of astronomers from the UK, France, Germany and the USA have found evidence for a dramatic surge in star birth in a newly discovered population of massive galaxies in the early Universe.In his talk at the RAS National Astronomy Meeting in Belfast on Tuesday 1 April, team...

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...

Mauna Kea Observatories -- Hawaii is Earth's connecting point to the rest of the Universe. The summit of Mauna Kea on the Island of Hawaii hosts the world's largest astronomical observatory, with telescopes operated by astronomers from eleven countries. The combined light-gathering power of the telescopes on Mauna Kea is fifteen times greater than that of the Palomar telescope in California -- for many years the world's largest -- and sixty times greater than that of the Hubble Space...
