They conclude that they are observing the remnant of a merger between two dwarf galaxies. This illustrates the scale-free character of galaxy formation, down to the lowest galactic mass scales.

New images of a nearby dwarf galaxy have revealed a dense stream of stars in its outer regions, the remains of an even smaller companion galaxy in the process of merging with its host. The host galaxy ...

New image captures 'stealth merger' of dwarf galaxies Date: February 8, 2012 Source: University of California - Santa Cruz Summary: New images of a nearby dwarf galaxy have revealed a dense stream ...

An international team of scientists led by David Martinez-Delgado (Max Planck Institute for Astronomy, Germany) has conducted research that reveals a “stealth merger” of dwarf galaxies, where ...

The Milky Way has grown by merging with smaller galaxies. Our galaxy is currently absorbing the Sagittarius Dwarf galaxy. In about 3-4 billion years, the Milky Way will merge with Andromeda.

Elliptical galaxies are thought to be a product of a galaxy merger. When two galaxies of equal mass merge, their stars start to tug on one another with gravity, disrupting the stars' rotation and ...

To celebrate its 25th anniversary, the Gemini North telescope team has released a stunning image of starburst galaxy NGC 4449, which is ablaze with intense star birth as it devours smaller galaxies.

A family portrait of the Andromeda galaxy and its orbiting dwarf satellites raises questions about how galaxies evolve.

Dark energy camera captures galaxies in lopsided tug of war, a prelude to merger Haley's Coronet and dwarf galaxy companion feel each other's gravitational forces as they begin to coalesce Date ...
