Using observations from the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has identified water vapour in the atmosphere of WASP-18 b, a massive extrasolar planet, a so-called hot Jupiter, with a temperature of around 2.700 °C. The result is published in the journal Nature. Exoplanet WASP-18 b is about 400 light-years from Earth, is 10 times more massive than Jupiter and has an orbital period of less than a day. Its extreme proximity to its star, its relative closeness to Earth, and its large mass

After a break of 4 years, on June 23rd and 24th the Teide Observatory will be celebrating its Open Days. This activity is free; its aim is to bring some knowledge of astronomy to the general public, including those people who happen to be visiting the island on those two days. To make a visit it is essential to register using a special form before June 16th. In this year’s edition the activity will be guided, and 9 points of interest will be visited, one every 20 minutes, so that the complete visit should take 3 hours, from 10:00 to 13:00 for the morning session, and from 16:00 to 19:00 for
