Composite Image of a Blob

Caption

This composite image shows one of the brightest objects observed in a study of 29 blobs located in a single field. Glowing hydrogen gas in the blob is shown by a Lyman-alpha optical image (colored yellow) from the Subaru telescope. A galaxy located in the blob is visible in a broadband optical image (white) from the Hubble Space Telescope and an infrared image from the Spitzer Space Telescope (red). Finally, the Chandra X-ray Observatory image (blue) shows evidence for a growing supermassive black hole in the center of the galaxy. Radiation and outflows from this active black hole are lighting up and heating the gas in the blob.
