Astronomers were left surprised after detailed studies showed that one of their subjects was not a single galaxy, but rather two, nearly perfectly superimposed on the sky to masquerade as one.

How supermassive black holes grow when galaxies collide

Experts have claimed that the notion black holes become supermassive by merging with other black holes is much more complex than previously believed.

Location of massive black holes discovered

Last Updated: Friday, October 18, 2013, 00:02

A research team has discovered that the more massive black holes tend to be located in galactic environments with higher density, thus indicating that galaxies in a dense area often merge together, causing the growth of massive black holes.

Astronomers have found the previously undiscovered `red nuggets` - small galaxies densely packed with red stars - near Earth.

Why disk galaxies eventually look similar

Last Updated: Thursday, September 12, 2013, 11:05

An astronomer has said that all kinds of flat, disk galaxies grow out of their irregular, clumped appearance and their older stars take the same smooth look, while predictably fading from a bright center to a dim edge.

20-year dark matter mystery `unravelled`

Last Updated: Wednesday, September 11, 2013, 14:52

Astronomers believe that they have found the answers to a 20-year debate over how dark matter is distributed in small galaxies.

Modified law of gravity predicts speed of dwarf galaxies

Astronomers have claimed that mature looking galaxies existed much earlier than previously known, when the universe was just about 2.5 billion years old.

Monster galaxies` appetite slows down with age

Last Updated: Friday, August 2, 2013, 13:02

New research from NASA`s Spitzer Space Telescope and Wide-field Infrared Survey Explorer (WISE) has found that, contrary to previous theories, gargantuan galaxies appear to slow their growth over time.
