August 12, 2009--The star-forming cloud Cepheus B glows red in a new picture made by combining data from the Chandra X-ray Observatory and the Spitzer Space Telescope.

The cloud, mostly made of cool hydrogen, is filled with very young stars. Studying the new images allowed astronomers to figure out that radiation from a bright, massive star outside the cloud is triggering star formation within.

"We essentially see a wave of star and planet formation that is rippling through this cloud," study co-author Eric Feigelson, of Penn State University, said in a statement.
