The Bubble Nebula (Aug 4 2012)  Image Credit & Copyright: Yves Van den Broek Blown by the wind from a massive star, this interstellar apparition has a surprisingly familiar shape. Cataloged as NGC 7635, it is also known simply as The Bubble Nebula. Although it looks delicate, the 10 light-year diameter bubble offers evidence of violent processes at work. Above and right of the Bubble's center is a hot, O star, several hundred thousand times more luminous and around 45 times more massive…

The Rosette Nebula is not the only cosmic cloud to evoke the imagery of flowers, but it is the most famous. At the edge of a large molecular cloud in Monoceros, the petals of this rose are actually a stellar nursery whose lovely, symmetric shape is sculpted by the winds and radiation from its central cluster of hot young stars. The stars in the energetic cluster are only a few million years old, while the central cavity in the Rosette Nebula, is about 50 light-years in diameter.

clouds of interstellar gas and dust — the raw material for new star formation. The nebula, located light-years away in the constellation Carina, contains a central cluster of huge, hot stars, called NGC 3603

This view shows part of the very active star-forming region around the Tarantula Nebula in the Large Magellanic Cloud, a small neighbour of the Milky Way. At the upper left is the brilliant but isolated star VFTS 682 and at the lower right is the very rich star cluster R 136.
