The single star nearest to the Sun is called Barnard’s star. A team of researchers led by the Instituto de Astrofísica de Canarias (IAC), has recently detected a ‘sub-Earth’ orbiting it. This exoplanet, called Barnard b has at least half the mass of Venus and orbits rapidly around its star, so that its year lasts only a little over three Earth days. This new exoplanet is sixteen times nearer to Barnard’d star than Mercury is to the Sun, and has a surface temperature close to 125oC, so it does not have liquid water on its surface. This discovery, led by the IAC in collaboration with a number

Yesterday saw the start of the 10th International School Astronomy Education Adventure in the Canary Islands (AEACI 2024) which will be celebrated during the full week in the IACTEC building in La Laguna (Tenerife), and which 65 teachers from 23 countries are attending. This school, organized by the Instituto de Astrofísica de Canarias (IAC) together with other scientific and educational institutions, has reached its tenth anniversary, and has given training in the teaching of astronomy to 600 teachers from all over the world. With the title “Explore the Universe with us” the AEACI 2024 has

Using observations made with the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has confirmed variations in morning and evening atmosphere of the exoplanet WASP-39 b, about 700 light-years away from Earth. The research has revealed differences in temperature and atmospheric pressure, as well as indications of different cloudiness and winds that could reach thousands of miles per hour. The results are published in Nature. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but
