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.

Scientists from the MAGIC collaboration, using a system of two 17m diameter imaging air Cherenkov telescopes located on the Canary Island of La Palma, Spain, have detected very high energy gamma-rays from a recurrent nova in the Milky Way. This event is the first one that has been detected at such energies and may provide new insight into this class of eruptions, and the potential role they play for producing the mysterious highly energetic cosmic rays that permeate the Milky Way. The researchers present the results of their observations and insights they gained into this type of stellar
