APOD


The "Bubble Nebula" has it's shape because of wind from a nearby star. The center of the galaxy houses an extremely hot "O Star" which is several hundred thousand times more luminous and 45 times as massive as our Sun. The nebula lies near the constellation Cassioepeia. I chose this photo because of it's supernatural appearance, and because Cassiopeia is an easy constellation to observe.
