The Submillimeter Array SMA News
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.

SMA Site Hawaii
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.
SMA Director: Dr. Ray Blundell
SMA Project Scientist: Dr. Eric Keto

"To determine whether the cloud contained clumps of denser gas, called dense cores, the team used the Submillimeter Array (SMA), a collection of eight radio telescopes on top of Mauna Kea in Hawaii."

Press Release:
March 23, 2015 Colliding Stars Explain Enigmatic Seventeenth Century Explosion New observations made with APEX and other telescopes reveal that the star that European astronomers saw appear in the sky in 1670 was not a nova, but a much rarer, violent breed of stellar collision. 
Press Release:
March 19, 2015 More than a million stars are forming in a mysterious dusty gas cloud in a nearby galaxy
article published
"The star cluster is buried within a supernebula in a dwarf galaxy known as NGC 5253, in the constellation Centaurus. The cluster has one billion times the luminosity of our sun, but is invisible in ordinary light, hidden by its own hot gases."  
January 20, 2015 Call for SMA Science Observing Proposals
The joint CfA-ASIAA SMA Time Allocation Committee (TAC) solicits proposals for observations for the period 16 May 2015 - 15 Nov. 2015. The SMA Observer Center website ( is open for proposal submission starting January 20, 2015.
Deadline extended to February 17, 4PM US EST  
November 7, 2014 The Role of Magnetic Fields in Star Formation
Massive stars tend to form in clusters as the gas and dust in molecular clouds collapses and fragments under the influence of gravity. In the classic picture of star formation, gravity must eventually compete against the thermal pressure that develops in the collapsing core as the material heats up.
