The Moon will be full early tomorrow, so it rises around sunset and remains in view for the rest of the night. But since the night is short, so is the time for moonwatching. This full Moon is in view for less time than any other of the entire year.

FaviconMoon and Saturn 18 Jun 2016, 1:00 am

The gibbous Moon has a couple of bright companions tonight. The planet Saturn looks like a bright star close to the Moon, with the fainter orange star Antares, the heart of the scorpion, to their lower right.

FaviconMoon and Companions 17 Jun 2016, 1:00 am

The Moon has some bright companions this evening. The brighest is orange Mars, to the right of the Moon at nightfall. Saturn stands farther to the lower left of the Moon, with the star Antares farthest from the Moon, almost directly below it.

FaviconESOcast 83: Ultracool Dwarf with Planets 2 May 2016, 11:00 am

Astronomers using telescopes at ESO's observatories in Chile have discovered three planets around a dim dwarf star just 40 light-years from Earth. These worlds have sizes and temperatures similar to those of Venus and the Earth, and they are the best targets so far found in the hunt for life elsewhere in the Universe.

FaviconESOcast 82: Zodiacal Light 4 Mar 2016, 4:00 am

The Atacama Desert in northern Chile is famed for its dark night skies, which can be enjoyed in their full glory thanks to the absence of light pollution. But even the darkest sky is not completely dark. Astronomers at ESO's observatories often encounter a natural light phenomenon above ESO’s telescopes known as the zodiacal light.
