Cepheus B: Trigger-Happy Star Formation

This composite image of X-rays from Chandra (violet) and infrared data from Spitzer (red, green, and blue) reveals a beautiful scene of star formation within our Galaxy. There are hundreds of very young stars inside and around the cloud -- ranging from a few millions years old outside the cloud to less than a million in the interior -- making it an important testing ground for star formation. By combining the data from these two observatories, researchers have shown that radiation from massive stars may trigger the formation of many more stars than previously thought.

Doing More with More

Back in 2002, we released a colorful image of the star-forming region known as 30 Doradus (also called the Tarantula Nebula.) At the time, we thought it was a beautiful image - and it was - of this pocket of intense stellar birth and death in the neighboring Large Magellanic Cloud.
