The robotic Transient Survey Telescope (TST) installed in the Teide Observatory of the Instituto de Astrofísica de Canarias (IAC) has successfully started its scientific observations. It is a 1 metre telescope which permits the detection of rapidly varying objects, and is set up to map the sky. The TST has been built and run via a public-private collaboration with Canary funding. The Transient Survey Telescope (TST) is a telescope with a 1 metre primary mirror, built to take long-term observations called surveys, for the detection of faint, rapidly varying objects over a wide area of the sky

An international team, in which the Instituto de Astrofísica de Canarias participates, has succeeded in mapping for the first time the three-dimensional structure of the atmosphere of an exoplanet, that is a planet beyond the Solar System. This research, published today in Nature , has been able to discover very strong winds that carry chemical elements such as iron and titanium, which create certain weather patterns through the planet's atmosphere. This mapping opens the door to more comprehensive and detailed studies of the chemical composition and climate of other planets. Enric Pallé

The Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) has confirmed the discovery of a super-Earth orbiting in the habitable zone of HD 20794, a nearby Sun-like star. This discovery, the result of over two decades of observations, opens a window to future studies of Earth-like planetary atmospheres. The search for planets in the habitable zone of Sun-like stars is crucial for understanding the possibility of life beyond Earth and for studying conditions similar to those that enabled the development of life on our own planet. In this context, HD 20794, a star
