rosette nebula

time for a good, old fashioned, pretty picture post.

behold, the rosette nebula (NGC 2237)!

the rosette nebula is a region where new stars are forming, about 5000 light years away from earth. the red dots, in the regions outlined in white, show hot, young stars, imaged with X-rays by the chandra space telescope.

the effect of the gushing big stars can be seen in the cavity they have created in the surrounding gaseous nebula. shown in purple, orange, green and blue colors are the older stars and gas in the region, as optically imaged by the digitized sky survey and the 0.9-meter telescope at the kitt peak national observatory in arizona.
