4C60.07
(Preview)
Astronomers taking a second look at a distant galaxy have found it is actually a pair of colliding galaxies, each harbouring a supermassive black hole at its centre. The existence of the black holes, which were fully formed less than 2 billion years after the big bang, suggests that these giant objec...

Galaxy cluster Abell 521
(Preview)
A team of scientists, including astronomers from the Naval Research Laboratory (NRL), have detected long wavelength radio emission from a colliding, massive galaxy cluster which, surprisingly, is not detected at the shorter wavelengths typically seen in these objects. The discovery implies...

LBG J2135-0102
(Preview)
LBG J2135-0102 (also known as the "Cosmic Eye" due to its morphological similarity to the Egyptian "Eye of Horus") was discovered from a Hubble Space Telescope (HST) image in an effort to survey high redshift galaxy clusters. This galaxy is a typical star-forming galaxy at z...
