GOODS Chandra Deep Field South - 033213.9-275000:
Hubble, Chandra & Spitzer have found evidence of a hidden population of supermassive black holes in the universe. One of two sources studied, named 033213.9-275000, appears as an X-ray source (shown in blue) without an optical counterpart in the Hubble image. The Spitzer infrared image demonstrates that the mysterious X-ray source is also detected at infrared wavelengths. This indicates that the galaxies around these supermassive black holes in the GOODS field are heavily obscured by dust.
