The heart of a distant Quasar
July 20, 2012
By linking three radio telescopes, Astronomers make the sharpest-ever observation of a distant quasar. The observation, two million times finer than human vision, via a “telescopic collaboration” that’s never been seen before, starts a new era in astronomical observation.

La Silla Star Trails North and South

Fix your camera to a tripod and you can record graceful trails traced by the stars as planet Earth rotates on its axis. If the tripod is set up at ESO’s La Silla Observatory, high in the Atacama desert of Chile, your star trails would look something like this. Photographer: Alexandre Santerne
