Description

Supergiant stars such as Betelgeuse have very extended atmospheres, the properties of which are poorly understood.
We observed Betelgeuse for 11 hours on 21 December 1996 with the Very Large Array (VLA) in its highest-resolution (A) configuration. At a wavelength of 7 mm, the angular resolution achieved (40 mas) is sufficient to have resolved Betelgeuse's atmostphere.
