Wallpaper Wednesday

This week’s wallpaper comes from the unappreciated (at least by the political masters in
Washington) Hubble Space
. The image shows the after affects of two
colliding galaxies

The two spiral galaxies started to interact a few hundred million years ago, making the
Antennae galaxies one of the nearest and youngest examples of a pair of
colliding galaxies. Nearly half of the faint objects in the Antennae
image are young clusters containing tens of thousands of stars. The
orange blobs to the left and right of image center are the two cores of
the original galaxies and consist mainly of old stars criss-crossed by
filaments of dust, which appears brown in the image. The two galaxies
are dotted with brilliant blue star-forming regions surrounded by
glowing hydrogen gas, appearing in the image in pink.
