There is more than one way to make a dwarf galaxy, and NASA's Galaxy Evolution Explorer has found a new recipe. The spacecraft has, for the first time, identified dwarf galaxies forming out of nothing more than pristine gas likely leftover from the early universe. Dwarf galaxies are relatively smal...

A new method to detect small, faint galaxies that spring up in the wake of violent galactic collisions has been devised by astronomers using the Spitzer Space Telescope. The method could shed light on how most of the galaxies near our own formed.
The vast majority of local galaxies are "dwarfs" –...

A Hubble Space Telescope image shows a dwarf galaxy, VCC128, at the centre, and the enlargement at right shows a double nucleus that suggests the presence of a black hole.
It is only the second time a supermassive black hole has been discerned in a dwarf galaxy, and only the third time that astronome...

An international team of astronomers using the Large Binocular Telescope (LBT) in Arizona has discovered that the Hercules Dwarf Galaxy is shaped like a cigar. That makes it an oddball among millions of its peers. The Hercules Dwarf is a companion galaxy to our own Milky Way, but has only one ten-mil...
