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

NASA's space telescope has produced a molecular and chemical portrait of the atmospheric constituents of exoplanet WASP-39 b, a Saturn-sized behemoth that orbit a star some 700 light-years away. The observations provide a full menu of atoms and molecules, and even signs of active chemistry and clouds. The suit of discoveries is detailed in a set of five scientific papers produced by an international collaboration involving research staff from the Instituto de Astrofísica de Canarias (IAC). WASP-39 b is a planet unlike any in our solar system. It is a so-called "hot Saturn" –a planet about as
