CHAINS KEEP US TOGETHER

At first glance, the dynamic of this striking galactic group seems obvious — the “bridge” of blue stars is connecting the upper galaxy to the bottom one. However, the lower galaxy is actually a distant object, and isn’t part of this interacting group known as Arp 194. 

In the mess of stars and gas stirred up by gravitational interactions, the galactic nuclei of the top galaxies can be seen. They are on a collision, and their slow attraction is responsible for the long tidal tail full of young star superclusters. The blue stream of stars extends for about 100,000 light-years.

Arp 194 can be found about 600 million light-years from Earth in the constellation of Ursa Major.

photos by (click pic) michael poliza, dennis fast and matthias brieter of polar bears amongst the fireweed in churchill, manitoba. the area has the largest, and most southerly, concentration of the animals on the planet. in late summer and early fall the polar bears make their way to the hudson bay, waiting for it freeze over so they can hunt for seals on the ice. but every year, the ice is forming later and later, forcing the polar bears to go hungry for longer.
