The Solar System research group at the Instituto de Astrofísica de Canarias (IAC) is participating in the international programme to keep a closet track of asteroid 2024 YR4. The aim is to determine its orbit with the highest possible precision before it stops being observable by ground based and satellite telescopes in April, and so improving our value of the probability that it will impact the Earth in 2032. In this context several telescopes of the Canary Observatories of the IAC are playing an outstanding role in this observing campaign: The Gran Telescopio Canarias (GTC) at the Roque de

The Instituto de Astrofísica de Canarias (IAC) and the KU Leuven , Belgium, have amplified their framework of collaboration in astrophysical research. The two institutions have signed an agreement which gives continuity to the operations of the Mercator Telescope at the Roque de los Muchachos Observatory (ORM), which started in 2002, and whose work will be strengthened by the installation of a new instrument called MARVEL (Mercator Array for Radial Velocities). Mercator is a semi-robotic telescope with a 1.2 metre primary mirror. Its name comes from that of the famous Flemish cartographer

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
