An ancient, ravenous black hole has been hiding an 11-billion-year-old galaxy in its glare

Astronomers have found an 11-billion-year-old galaxy that absorbs more light than other galaxies found in a similar fashion.

Using the Hubble Space Telescope , astronomers used a tricky technique to find out what light had passed through on its way to telescopes.

As light passes through a background galaxy toward a foreground galaxy, for instance, gas and dust in the foreground galaxy will absorb some of the background one's wavelengths.
