The star cluster NGC 3766

This pan video gives a close-up look at a spectacular group of young stars — the open star cluster NGC 3766 in the constellation of Centaurus (The Centaur). Very careful observations of these stars by a group from the Geneva Observatory using the Swiss 1.2-metre Leonhard Euler Telescope at ESO’s La Silla Observatory in Chile have shown that 36 of the stars are members of a new and unknown class of variable star.
