The WASP and SOPHIE collaboration has announced the discovery of WASP-3b, one of the hottest exoplanets discovered so far. At a temperature of more than 1700 degrees Celsius WASP-3b has the potential to place stringent constraints on exoplanet atmospheric models. The adaptive optics system of the William Herschel Telescope was used to exclude the possibility of a nearby eclipsing-binary system being the cause of the transits.

A team of UK, French and Swiss astronomers has discovered two new Jupiter-sized extrsolar planets, WASP-1b (also named as Gara

When comet Tempel 1 came into view from La Palma, some 16 hours after the NASA Deep Impact probe struck the comet, members of the La Palma Deep Impact Collaborating Observers team were able to start tracking the target comet with the 2.5m Isaac Newtow Telescope.

The Near Earth Asteroid 2002 NY40 was observed with the William Herschel Telescope on La Palma, Canary Islands, on the night of August 17 to 18, 2002. The asteroid was imaged just before its closest approach to Earth, using the Adaptive Optics system NAOMI. These are the first images of a Near Earth Asteroid obtained with an Adaptive Optics system.
