The Advanced Camera for Surveys (ACS), the newest camera on NASA's Hubble Space Telescope, has captured a spectacular pair of galaxies engaged in a celestial dance of cat and mouse or, in this case, mouse and mouse.
Located 300 million light-years away in the constellation Coma Berenices, the colliding galaxies have been nicknamed "The Mice" because of the long tails of stars and gas emanating from each galaxy. Otherwise known as NGC 4676, the pair will eventually merge into a single giant galaxy.
The image shows the most detail and the most stars that have ever been seen in these galaxies. In the galaxy at left, the bright blue patch is resolved into a vigorous cascade of clusters and associations of young, hot blue stars, whose formation has been triggered by the tidal forces of the gravitational interaction. Streams of material can also be seen flowing between the two galaxies.
The clumps of young stars in the long, straight tidal tail [upper right] are separated by fainter regions of material. These dim regions suggest that the clumps of stars have formed from the gravitational collapse of the gas and dust that once occupied those areas. Some of the clumps have luminous masses comparable to dwarf galaxies that orbit in the halo of our own Milky Way Galaxy.

Specialty Photographic, LLC is a very small family owned company. I am a collector at heart, and this website is a collection of my very favorite sharable images that I've found on the web. We also have a number of fine art paintings created by Phyllis Athy and photography by Dale Athy.
If you are shown in a photo, or feel a photo violates your copyrights, and object to it being available on our site, please contact us and the image will be removed (I'll need a way to contact you).
Special thanks go to Jon Sullivan and his PDPhoto.org website. Much inspiration and insight came from looking through his site. If you look through our site, you will find many of Jon's generously provided (and excellently photographed) public domain photos. Special thanks to Wikimedia Commons and all of the generous contributors found there. You will find many of our photos come from this enormous reservoir of images.
I hope you enjoy them as I do.
