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 ...

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 ...

D ozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space Telescope, which took more than a thousand orbits of the Earth to take ...

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 ...

These final observations at Subaru in 2011 clearly showed the stealth merger of two dwarf galaxies. Modern cosmological theory posits that large galaxies were built up from smaller ones through an ...

But the galaxy’s merger-mania continues. Astronomers see evidence that the Milky Way has gobbled up as few as five and perhaps as many as 11 small galaxies in the past few hundred million years.

NGC 2623 in the constellation Cancer the Crab is the product of the merger of two spiral galaxies some 250 million light-years away. ... several globular clusters begin to form a dwarf galaxy.

This week’s image from the Hubble Space Telescope shows no less than three galaxies that are in the process of merging to become one, called IC 2431. Located 681 million light-years away in the ...

“Our own galaxy is a merger of smaller galaxies, and it’s still merging.” In other words, the Milky Way itself may have started out as a dwarf galaxy with only a few hundred to thousand stars. Today, ...

This other recent Hubble image also shows a dwarf galaxy, one called NGC 5238. This one is located 14.5 million light-years away, but has a different and more complex type of structure.
