An international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has discovered the extremely eccentric orbit of a gas giant exoplanet. This world, called TIC 241249530 b, not only follows one of the most drastically stretched-out orbits of all known transiting exoplanets, but also is also orbiting its star backwards, lending insight into the mystery of how these high-mass gas giants evolve into hot Jupiters , with very close and circular trajectories. The study is published in Nature. Within the population of known exoplanets, there are those that

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

Este viernes 12 de julio, el presidente del Cabildo de La Palma, Sergio Rodríguez, ha recibido al nuevo director del Instituto de Astrofísica de Canarias (IAC), Valentín Martínez Pillet, en la sede del Cabildo de La Palma, con el objeto de poner en común los objetivos de ambas entidades. Al encuentro han acudido, también, el director saliente del IAC, Rafael Rebolo, y el administrador del Observatorio del Roque de los Muchachos, Emilio García. El presidente del Cabildo, Sergio Rodríguez, ha agradecido “tanto al director saliente, Rafael Rebolo; como el director entrante, Valentín Martínez

This educational programme, organised and developed by the scientific institutions of the Roque de los Muchachos Observatory and the Instituto de Astrofísica de Canarias (IAC), is celebrating its 14th birthday, and it does so with unanmiously high opinions from the schools which have participated in the programme this year. This can be gleaned from the data in the questionnaire circulated by the IAC among the educational centres which participated in this edition of the programme in 2024, which reflect 100% satisfaction. In 2024 the programme included 14 lectures in educational centres, and
