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).

However, high angular resolution observations with ALMA opened a new window to understand their formation environment in further details.

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.

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.
