Black Holes Churn Up Interstellar Dust - Universe Today
The supermassive black holes at the heart of most galaxies put out so much energy they churn the interstellar dust that surrounds them. NASA's Chandra X-Ray Observatory recently took a series of images of 56 elliptical galaxies, and revealed that the hot gas and dust blasting out X-rays have a different distribution from the stars we can see. This gas and dust should have settled down millions of years ago, but it appears that these black holes are feeding so voraciously that they're continuously stirring up the material.
