Above is a composite image of the spiral galaxy NGC 4151, located 43 million light years away from Earth. It is one of the nearest galaxies that has a growing black hole. The image shows x-ray data from the Chandra observatory (blue) and optical data that shows positively chaged hydrogen from the Jabobus Kapteyn Telescope on La Palma, in the Canary Islands (yellow). The yellow orbs are where a star has recently formed. A ring of neutral hydrogen shown in red comes from observations from the National Science Foundation's Very Large Array in New Mexico.
