Cambridge, MA -- Smithsonian astronomers watched as the "Impactor" probe from NASA's Deep Impact spacecraft hit Comet Tempel 1 earlier this week. They monitored the impact using the ground-based Submillimeter Array (SMA) in Hawaii and NASA's orbiting Submillimeter Wave Astronomy Satellite (SWAS). Results are still coming in, but so far the scientists report seeing only weak emission from water vapor and a host of other gases that were expected to erupt from the impact site. The most...

Cambridge, MA -- The Submillimeter Wave Astronomy Satellite (SWAS) has been asleep on orbit for the past 11 months. SWAS operators placed it into hibernation after a highly successful 5.5-year mission highlighted by the discovery of a swarm of comets evaporating around an aging red giant star. Now, they have awakened SWAS again for the first-ever opportunity to study a comet on a collision course with a U.S. space probe. "We knew there was life left in SWAS," said SWAS Principal Investigator...

PORT COQUITLAM, British Columbia (AP) -- To examine data on the universe's earliest stars and galaxies from a balloon-launched telescope, scientists had to fend off earthly creatures in the Canadian Arctic. The telescope landed there by parachute Saturday and was quickly surrounded by wildlife. "The secret of our universe's beginnings was being protected by caribou and polar bears," said John Kageorge, communications manager for AMEC Dynamic Structures Ltd. in this Vancouver suburb. "As it...

Cambridge, MA -- The Submillimeter Array (SMA) will be ready and watching when NASA's Deep Impact probe strikes the nucleus of Comet Tempel 1 on July 4th. The impact is expected to excavate material from the comet's interior - material left over from the earliest days of our solar system. "The SMA will be the only operational millimeter or submillimeter array observing Tempel 1 at the time of the impact" said astronomer Charlie Qi of the Harvard-Smithsonian Center for Astrophysics (CfA). "As...

Cambridge, MA -- Astronomers find jets everywhere when they look into space. Small jets spout from newborn stars, while huge jets blast out of the centers of galaxies. Yet despite their commonness, the processes that drive them remain shrouded in mystery. Even relatively nearby stellar jets hide their origins behind almost impenetrable clouds of dust. All stars, including our sun, pass through a jet phase during their "childhood," so astronomers are eager to understand how jets form and how...

Cambridge, MA -- Astronomers are meeting this week in Cambridge, Mass., to discuss recent advances generated by a new astronomical facility-the Submillimeter Array (SMA) on Mauna Kea, Hawaii. A joint project of the Smithsonian Astrophysical Observatory (SAO) and the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA), the SMA has opened a new window onto the cosmos by observing radiation from some of the coldest, dustiest, and most distant objects in the universe. "The SMA is...

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...
