Travelers In The Night

The ALMA radio telescope located in the Atacama desert of northern Chile is able to see the faint millimeter wave length glow emitted by gas molecules and dust particles in the disk of material surrounding the very young star named HD 163296. This solar system in formation is located about 400 light years away in the constellation of Sagittarius. HD 162396's age compared to our Sun is like that of a 3 day old human baby compared to a 65 year old adult.
