February 10, 2009 SMA Image Contest 2009 The Submillimeter Array (SMA) announces its first Image Contest. Much like the annual NRAO "Radio Astronomy Imaging Contest", the purpose of this contest is to gather visually compelling images based on SMA data from the SMA user community to be used for a variety of purposes, including public outreach.

The Submillimeter Array (SMA) is an 8-element radio interferometer located atop Mauna Kea in Hawaii. Operating at frequencies from 180 GHz to 700 GHz, the 6m dishes may be arranged into configurations with baselines as long as 509m, producing a synthesized beam of sub-arcsecond width. Each element can observe with two receivers simultaneously, with 2 GHz bandwidth each. The digital correlator backend allows flexible allocation of thousands of spectral channels to each receiver.

The Submillimeter Array is a joint project between the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy and Astrophysics and is funded by the Smithsonian Institution and the Academia Sinica.
 
June 15, 2009 Planetary Preemies?
by Johannes Hirn with www.skyandtelescope.com
"Protoplanetary disks around three young stars in Ophiuchus have large central holes, astronomers have found, which were presumably cleared by still-growing Jupiter-mass planets. But there is a problem: the stars are too young. How would planets have formed in just a couple million years?"  Read More...
June 11, 2009 Magnetic Fields Dominate Young Stars of all Sizes?by Anne Minard with www.universetoday.com "A team of researchers led by Josep Girart, of the ICE - Institut de Ciències de l'Espai (in Spain), studied the slow evolution of a dust cloud into a massive star, and realized that the cloud's magnetic field controls the star's development more than any other factor."  Read More...
June 11, 2009 Planet-forming Disk Discovered Orbiting Twin Suns published in www.sciencedaily.com Astronomers have announced that a sequence of images collected with the Smithsonian's Submillimeter Array (SMA) clearly reveals the presence of a rotating molecular disk orbiting the young binary star system V4046 Sagittarii.  Read More...
June 9, 2009 Cosmic Cloud Poised to Birth Massive Star by Andrea Thompson with Space.com "A massive, tranquil object found lurking in a dark cloud in our galaxy could be about to transform into a massive star or stars, giving astronomers their first glimpse at such a region on the cusp of stellar birth."
