An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC), the University of Liège and collaborators in UK, Chile, the USA, and Europe, has discovered a transiting giant planet orbiting the smallest known star to host such a companion — a finding that defies current theories of planet formation. The host star, TOI-6894 , is a red dwarf with only 20% the mass of the Sun , typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or retaining giant planets. But as published today in

ESA’s Hera mission for planetary defense performed a flyby of Mars, as part of its gravitational assistance manoeuvre to shorten its journey to the binary asteroid system Didymos. During the flyby, the spacecraft came around 5000 km from the surface of Mars, having also the opportunity to obtain images of its two moons, Deimos (during the approach) and Phobos (when departing Mars). Julia de León, Javier Licandro, and George Prodan, researchers at the Instituto de Astrofísica de Canarias, participate in this mission, successfully launched from Cape Cañaveral, Florida (USA) on October 7, 2024

The Instituto de Astrofísica de Canarias (IAC) is once again participating in the Miniferias de la Ciencia y la Innovación en Canarias, reinforcing its commitment to popularising science and bringing astronomy closer to the Canarian public. Through its Scientific Communication and Culture Unit (UC3), the research centre is taking part in the activities organised in La Palma from 22 to 24 May. Become astro-detectives for a day Astrophysicists and popularisers Alfred Rosenberg and Alejandra Goded lead the activity ‘Astro-detectives: How do astrophysicists study the Universe?’, an interactive
