Zware sterren kunnen verrassend snel ontstaan

ATLASGAL

The ATLASGAL survey covers two thirds of the surface area of the Galaxy within 50,000 light years of the Galactic center. Thus it includes practically all (97%) of the star-formation within the Solar Circle, i.e. the inner Galaxy. The image displays a part of ATLASGAL, a region located between the giant molecular complexes called W33 and M17 in the Sagittarius constellation. One region corresponds to a cold, pristine massive clump (upper left inset), and another one to a young massive star (upper right inset). In the lower right inset we present a schematic of the Milky Way and show the position of the Solar Circle (green) and region of the Galaxy covered by ATLASGAL (shaded region).
