The
famous red supergiant VY CMa experienced a very massive mass-loss event
a few hundred years ago. A clump with a minimum mass of 10x Jupiter is
currently traveling out from the star and now about 1" to the SW. The
clump is clearly seen in both scattered light at 1 and 2 microns and in
thermal emission at 9 microns. Gordon
et al. 2019. The
9 micron image was taken using NOMIC at the LBT combined focus. Hoffmann
et al. 2017
