W75N(B)-VLA2

W75N(B)-VLA2 is a massive protostar about 300 time brighter than our Sun observed since 1996. By 2015 its stellar wind changed from a compact spherical form to a larger thermal, ionized elliptical one outlining collimated motion, giving critical insight into what happens as a massive star forms.^[1]^[2] Being able to observe its rapid growth as it happens (in real time in an astronomical context) is unique, according to Huib van Langevelde of Leiden University, one of the authors of a study of the object.
