Image 1 - Astronomers Use ALMA To Dissect Nearby Planetary System
2012-04-12 11:46:36

[ Watch the Video ] Astronomers have made a breakthrough discovery in understanding a nearby planetary system, giving clues about how these systems form and evolve. Scientists used the Atacama Large Millimeter/submillimeter Array (ALMA) to find that planets orbiting the star Fomalhaut must be smaller than originally thought. The high-resolution images show that both the inner and outer edges of the thin, dusty disk have very sharp edges.  This, as well as computer simulations,...

NEWTON, N.C., Oct. 3, 2011 /PRNewswire/ -- Thirteen 12-meter antennas manufactured by General Dynamics SATCOM Technologies have been successfully installed at the 16,500-foot-high Chajnantor plateau in Chile, home to the Atacama Large Millimeter/submillimeter Array (ALMA) astronomical observatory. Located in the Andes mountains, the 115-ton, highly specialized antennas form part of an 11-mile-wide international astronomy project. When it is completed in 2013, scientists will use the...

New Telescope Opens For Business In Chile's Atacama Desert
2011-10-03 09:36:24

[ Watch the Video ] Astronomers have opened up its doors to a new ground-base telescope that will help give scientists a peak at the places that have never been explored. The Atacama Large Millimeter/submillimeter Array (ALMA) has released an image of a merging pair of galaxies as part of its grand opening. ALMA is the largest and most expensive radio observatory on Earth and was funded by several different space agencies. Radio observatories collect tiny waves given off by the...

Enceladus Influences Saturn's Chemical Composition
2011-09-21 12:59:20

   Chalk up one more feat for Saturn's intriguing moon Enceladus. The small, dynamic moon spews out dramatic plumes of water vapor and ice -- first seen by NASA's Cassini spacecraft in 2005. It possesses simple organic particles and may house liquid water beneath its surface. Its geyser-like jets create a gigantic halo of ice, dust and gas around Enceladus that helps feed Saturn's E ring. Now, thanks again to those icy jets, Enceladus is the only moon in our solar system known to...

Cryogenic Catering Truck Comes To ALMA Observatory
2011-09-04 05:28:16

  The ultimate in high altitude, high-tech catering has arrived in Chile to serve chilled "provisions" to the telescopes at the largest astronomical complex in the world, the Atacama Large Millimeter/submillimeter Array (ALMA). Until now, servicing the state-of-the-art superconducting receivers inside an ALMA telescope has required hauling the entire 115-ton telescope from its observing site at 16,500 feet down to a support facility at 9,500 feet. The dangerous 40-mile roundtrip,...

Getting ready for ALMA's first scientific observations The first European antenna for the Atacama Large Millimeter/submillimeter Array (ALMA) has reached new heights, having been transported to the observatory's Array Operations Site (AOS) on 27 July 2011. The 12-meter diameter antenna has arrived at the Chajnantor plateau, 5000 meters above sea level. Here, it joins antennas from the other international ALMA partners, bringing the total number at the AOS to 16. Although 16 sounds like just...

A team of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The researchers found a mass of water vapor that is at least 140 trillion times that of all water in the world's oceans combined, and 100,000 times more massive than the sun. The team said the light has taken 12 billion years to reach Earth, and the astronomers were observing the light when the universe was just 1.6 billion years old. "The environment around this quasar is unique...

Submillimeter observatories penetrate cold, dusty galaxies to see stars forming in the primeval past A chance alignment of galaxies, recently observed by a space observatory, presents the perfect opportunity for studying star-forming galaxies billions of light-years away. For decades, astronomers have used Einstein's concept of a "gravitational lens" to study the magnified images of distant objects.  A lensing effect occurs when a massive object, such as a galaxy, is located exactly...

It turns out the Herschel Space Observatory has a trick up its sleeve. The telescope, a European Space Agency mission with important NASA contributions, has proven to be excellent at finding magnified, faraway galaxies. Like little kids probing patches of dirt for insects, astronomers can use these new cosmic magnifying lenses to study galaxies that are hidden in dust. "I was surprised to learn that Herschel is so good at finding these cosmic lenses," said Asantha Cooray of the University of...

Astronomy & Astrophysics is publishing a special feature devoted to the first science results obtained with Herschel, an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA. Herschel was launched on May 14, 2009, and progress since launch with various webreleases can be followed on the Herschel Science Centre Latest News webpage at http://herschel.esac.esa.int/latest_news.shtml. Herschel has a...

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...
