«The SMA's unique capability to measure polarization at high angular resolution allowed access to the magnetic fields at the smallest spatial scales,» said SMA director Ray Blundell (CfA).
Relying on telescopes in Arizona and Hawaii (which would eventually be part of the EHT), they tried to get observations of Sagittarius A * at higher angular resolutions than had been possible before, but failed to detect the signals they expected to see in the immediate vicinity of the black hole.

The list of accomplishments is far too large to fit within one article, but they include: the first search for extraterrestrial intelligence; creation of the Drake equation; discovery of flat galactic rotation curves; first pulsar discovered in a supernova remnant; first organic polyatomic molecule detected in interstellar space; black hole detected at the center of the Milky Way; determination of the Tully - Fisher relationship; detection of the first interstellar anion; measurement of the most massive neutron star known; first high angular resolution image of the Sunyaev - Zel» Dovich Effect; discovery of only known millisecond pulsar in a stellar triple system; discovery of pebble - sized proto - planets in Orion, and the first detection of a chiral molecule in space.
On January 10, 2006, astronomers using the infrared Center for High Angular Resolution Astronomy (CHARA) Array announced that Vega rotates so fast (at around 91 percent of its «break - up rate») that it is cooler as well as 23 percent wider along its equator than at its poles due to the gravitational effect of its «middle bulge» (NOAO press release; AAS 207 session summary); and Aufdenberg et al, 2006).
The observations made possible by the band 9 receivers allow astronomers to study molecular clouds — the dense regions of gas and dust where new stars are being born — at higher temperatures and densities, and with higher angular resolution, thus complementing the longer wavelength bands.
