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.

Binary planetary systems caught in the act of forming! by Phil Plaiti with www.discovermagazine.com "Astronomers have discovered a young binary system where both stars are surrounded by thick disks of material that are in the process of forming planets! And it's a near thing, too -- this system almost didn't exist at all. " Read More...

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... Prior Events > | |||||||||||
