Jeweled Eyes in the Sky

These shape-shifting galaxies have taken on the form of a giant mask. The icy blue eyes are actually the cores of two merging galaxies, called NGC 2207 and IC 2163, and the mask is their spiral arms. The false-colored image consists of infrared data from NASA's Spitzer Space Telescope (red) and visible data from NASA's Hubble Space Telescope (blue/green).

NGC 2207 and IC 2163 met and began a sort of gravitational tango about 40 million years ago. The two galaxies are tugging at each other, stimulating new stars to form. Eventually, this cosmic ball will come to an end, when the galaxies meld into one. The dancing duo is located 140 million light-years away in the Canis Major constellation.

The infrared data from Spitzer highlight the galaxies' dusty regions, while the visible data from Hubble indicates starlight. In the Hubble-only image (not pictured here), the dusty regions appear as dark lanes.

The Hubble data correspond to light with wavelengths of .44 and .55 microns (blue and green, respectively). The Spitzer data represent light of 8 microns.

A bright spot on the image's left edge is thought to harbor a black hole.

I wonder how they know the two galaxies are merging. Maybe the smaller one is just several lightyears 'behind' the larger galaxy.

The red, it's dust heating up (normally it's dark, and "cool", not glowing hot in infra-red)

Looks like an old fashioned moustache. I wonder if nasa said that.

Looks more like the face of a demon watching over us.

Nice picture !

All i can say is that looks amazing, i wonder what it's like after it's collided.

Most spirals that merge end up as elliptical galaxies, these mergers do cause a significant loss in stars as they are blown off by gravitional forces..

hmmm... interesting.

think about how small stars are compared to the gaps between them... the odds of even two stars colliding in a situation like this are tiny... it's really only the gravitational effects that would make them interact.
