Does every little thing in rental high-tail?

The arc of the Milky Way galaxy shimmers over the La Silla Observatory in Chile in this gorgeous night-sky view by European Southern Observatory (ESO) photo ambassador Petr Horálek. In the center of the image is the ESO 3.6-metre telescope, and to its left is the Swiss 1.2-metre Leonhard Euler telescope. Visible beneath the righthand limb of the Milky Way's starry arc are the Large and Small Magellanic Clouds, two satellite galaxies of the Milky Way. Saturn is visible under the left side of the arc, with Jupiter glowing brightly just above it and slightly to the left. — (Image credit rating: Petr Horálek/ESO)
