Very cool photo of the Southern sky in the Slate “Bad Astronomy” blog:

Southern skies over the Very Large Telescope

The southern stars of Carina and Crux hang over the Very Large Telescope.

What grabs your attention right away is the stunning starscape. This picture was taken in Chile, at a latitude of 24 degrees south. Many of the stars seen here never rise for those of us who live in the Northern Hemisphere; the Earth is forever in the way. We’re looking in a direction toward the Milky Way, so we see lots of stars scattered about—it’s like looking toward the downtown of a city from a suburb.

Most of the stars you see here are part of the constellation Carina, representing the keel of a ship. The brightest star in the picture, though, the blue one on the right, is called Acrux, one of the stars in Crux, the famous Southern Cross. Crux is a kite-shaped figure, with Acrux at the top and the other three to the lower left.

Dominating the shot is the ruddy glow of the mighty Carina Nebula, a vast, sprawling complex of gas and dust so large, so massive, that it’s hard to describe, let alone grasp.
