A Galaxy Collision in NGC 6745
In the lower right side of the picture, a smaller galaxy is colliding with a larger one in NGC 6745. No stars exactly collided, though dust, gas an ambient magnetic fields did. Some of the larger's galaxy's gas pulled away to create a smaller smaller in the process. This galaxy is 80 thousand light-years across and 200 million light-years away.
I find this picture the only exciting one for this week- all of the others seem rather dull and boringly simulated. I normally go for the more colourful and detailed pictures anyway, but this is ok.
