An international research, in which the Instituto de Astrofísica de Canarias (IAC) participates, has discovered a new planetary system comprised of 4 planets orbiting the star TOI-500. This is the first system known to host an Earth analogue with a period shorter than one day and 3 additional low-mass planets whose orbital configuration can be explained via a non-violent and smooth migration scenario. The study is published in the journal Nature Astronomy. The inner planet, dubbed TOI-500b, is a so-called ultra-short period (USP) planet, as its orbital period is only 13 hours. It is regarded

A study led by the researcher of the Instituto de Astrofísica de Canarias Maitane Urrutia-Aparicio has shown the relevance of sunrise on Easter Sunday, one of the most important Christian festivities, in the orientation of Romanesque churches on the Camino de Santiago. This work exposes the close relationship between the sky and the orientation of the constructions of the Jacobean Route. It also shows that medieval societies already included temporal symbolism in the construction of their temples. The latest research results have been published in the journal Sustainability.

Patricia Bessiere, a researcher at the Instituto de Astrofísica de Canarias (IAC), has led research which has used data from the KECK telescope in Hawaii to understand the impact that active galactic nuclei have on star formation in their host galaxies. The results are published today in the journal Monthly Notices of the Royal Astronomical Society Letters. One of the key questions that astronomers are trying to answer is ‘Why do galaxies look the way they do?’. Computer simulations of how galaxies formed and evolved suggest that there should be many more very large galaxies than we actually

The gravitational force needed for the universe to evolve from when it was almost uniform, during the Big Bang, until galaxies, stars, and planets were formed is provided by the “dark matter”. But in spite of the essential role of this basic component, which is estimated to make up some 80% of the matter in the universe, scientists know virtually nothing about its nature, behaviour, and composition, which is one of the main challenges in current physics and cosmology. Aiming to give answers to these questions the researcher Diego Blas, Senior Lecturer in the Department of Physics of King’s
