This chart of the constellation of Sagittarius (The Archer)

This chart shows the rich constellation of Sagittarius (The Archer) and marks the position of the star HD 163296. This star has a mass about twice that of the Sun, but is just four million years old. It is a little too faint to be seen with the unaided eye, but can easily be picked up with binoculars, not far from the famous Trifid Nebula and Lagoon Nebula. Credit: ESO, IAU and Sky & Telescope
