Wolf-Rayet Nebula is a nebula which surrounds a Wolf-Rayet star. There are different types of WR-nebula, based on their formation mechanism: 1.HII regions 2.ejecta-type nebulae 3.wind-blown bubbles 4.neutral hydrogen voids and shells (may be associated gas). The nebula shown is a 'wind-blown bubbles' type.

The Dandelion Cluster is a group of stars located 5000 light years away from us, backdropped by the center of the galaxy. This cluster collapsed from a large gas cloud about 200 million years ago and weighs about 300 solar masses. Remnants of the cloud are visible, blocking light from the stars behind them. There are so many stars….
