UNDARK is a pioneering project led by the Instituto de Astrofísica de Canarias (IAC) bringing together outstanding international institutions in the fields of astrophysics, cosmology, and particle physics. Funded for three years via the 'Widening' programme of the European Union, its objective is to tackle one of the major puzzles of contemporary physics: the dark universe. The major part of the Cosmos is composed by the so-called “dark universe”. Barely 18% of the total matter in the universe is made up of the elements in atoms with which we are familiar, while the remaining 82%, termed

The European Southern Observatory (ESO) has signed an agreement with an international consortium of institutions, including the Instituto de Astrofísica de Canarias (IAC), the Instituto de Astrofísica de Andalucía (IAA) and the Centro de Astrobiología de Madrid (CSIC-INTA), for the design and construction of ANDES, the ArmazoNes high Dispersion Echelle Spectrograph. The instrument will be installed on ESO’s Extremely Large Telescope (ELT). It will be used to search for signs of life in exoplanets and look for the very first stars, as well as to test variations of the fundamental constants of

An international research, in which the Instituto de Astrofísica de Canarias (IAC) has played a leading role, has found a planet of intermediate size between Earth and Venus orbiting a cool red dwarf 40 light-years away. The new world, named Gliese 12 b, lies within the habitable zone of its star, making it a promising candidate for the James Webb Space Telescope to study its atmosphere. The discovery was made possible thanks to observations from NASA's TESS satellite and other facilities such as CARMENES, at Calar Alto Observatory (CAHA), and MuSCAT2, installed at the Carlos Sánchez

The Euclid Consortium announces the publication of its first papers, demonstrating the space mission's ability to search for wandering planets, study the dark matter of galaxies and explore the evolution of the Universe. Five new images with unprecedented resolution are also published. Spain plays an important role in the Euclid mission where, in addition to being part of the consortium that has led the mission since its inception, it has also participated in the instrumental development of the project and contributes significantly to its scientific exploitation.

An international scientific team, with the participation of researchers from the Instituto de Astrofísica de Canarias (IAC), has found a new world similar in size to our planet orbiting an ultra-cold red dwarf located about 55 light-years away. Observations from the SPECULOOS telescope network, which includes the ARTEMIS telescope at the Teide Observatory in Tenerife, have made this discovery possible. The Gran Telescopio Canarias (GTC), at the Roque de los Muchachos Observatory on La Palma, has also played a key role in confirming the discovery, providing some of the most accurate ground
