Observatories: The Submillimetre Array (SMA) at Mauna Kea, Hawaii

Sub-millimeter. Blue steel reflectors. But no, its not the 1st of April and this is not about the Derek Zoolander Center For Astrophysicists Who Wanna See Good And Learn To Do Other Stuff Good Too.

The SMA is actually a real-person-sized array of specialized radio receivers, 4080 m up a dormant volcano in Hawaii. It is run jointly by the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy and Astrophysics.  

 

Situated atop Hawaii's Mauna Kea, the SMA's eight 6m antennas receive the 0.3 to 1.7mm wavelengths at 180-250 GHz, 266-355 GHz, 320-420 GHz and 600-700 GHz .


"The SMA can achieve ... at least 60 times sharper images than those the existing submillimeter-wave single-dish telescopes can provide. It can be arranged into configurations with baselines as long as 509 m, allowing us to observe submillimeter emission from warm, dense gas and dust at unprecedented high resolutions of up to 0.1 arcsecond."
