The exoplanets closest to us offer the best opportunities to make a detailed study of their physical properties, including the search for life outside the Solar System. In research led by the University of Göttingen (Germany), in which the Instituto de Astrofísica de Canarias and the University of La Laguna (ULL) are participants, has detected a system of superearths in orbit round the nearby star Gliese 887 (GJ 887), the brightest red dwarf in the sky. The results are published today in the journal Science. Superearths are planets with a larger mass than the Earth, but substancially less

An international team of scientists, with the participation of the Instituto de Astrofísica de Canarias (IAC), has discovered a planet of the size of Neptune orbiting in rather more than a week around AU Microscopii, a young star a little over of 30 light years away, and surrounded by a disc of debris left over from its formation. The data were obtained with NASA’s Transiting Exoplanet Survey Satellite (TESS) and the Spitzer Space Telescope (now retired from service). The Discovery is published today in Nature magazine. The finding in this system, abbreviated as AU Mic, will be a unique

This Tuesday October 20th at around 23.12 hr (Canary time) the NASA space probe OSIRIS-REx will make its first attempt to collect samples from the asteroid (101955) Bennu. The Instituto de Astrofísica de Canarias (IAC) has played an active role in the mission since 2011. Researchers Julia de León, Javier Licandro, Eri Tatsumi and Juan Luis Rizos, who are members of the science team of OSIRIS-REx will be present telematically at the meeting organized by this NASA mission so that the science team can follow in real time this dangerous maneuvre¸ using the SamCam camera on board the probe.
