An international team of scientists, with participation by researchers at the Instituto de Astrofísica de Canarias (IAC), has discovered a very large, but thin, stream of stars in the Coma cluster of galaxies. This is the largest stream of stars detected until now, and the first to be found in a cluster of galaxies. This finding, which is published in the journal Astronomy and Astrophysics, was made using observations taken with the William Herschel Telescope (WHT) at the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands). The Coma Cluster is a large cluster of galaxies

An international collaboration, with participation by the Instituto de Astrofísica de Canarias (IAC), has found a system of six exoplanets orbiting a central star with a precise rhythm.This phenomenon, known as orbital resonance, is common during the starting phase of planet formation, but it is exceptional to find a system with such a large set of planets which conserves this kind of gravitational synchronism. This finding shows that the system has not undergone major changes during its six billion year history, so that it gives an unusual view of the formation and evolution of planets. The

The XXXIV Canary Islands Winter School of Astrophysics closed last Thursday, November 16, with the visit to the facilities of the Obervatorio del Teide. For two weeks, 54 graduate students from 15 countries attended the IACTEC building to learn about the latest developments in the field of galaxy evolution and the Local Group. Currently, astrophysics field is receiving a big amount of data available for research due to the Gaia Mission and several spectroscopic surveys from Earth in which the IAC has a large participation. The organization highlights the great enthusiasm, the good atmosphere

The official inauguration of the CosmoLab 2023-2027 project, an educational project to create an astronomical community in the schools of the island of Tenerife, took place last Friday 17th at the Observatorio del Teide (OT). The inauguration was attended by the Island Councillor for Innovation of the Cabildo de Tenerife, Juan José Martínez, the director of the Instituto de Astrofísica de Canarias (IAC), Rafael Rebolo, and directors and STEAM representatives from the four teaching centres on the island of Tenerife. They all enjoyed a tour of the facilities, an astronomical observation with

An international research team, led from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) together with a group of Italian universities, has confirmed a new method for finding protoclusters of galaxies, the largest structures in the early universe. These progenitors of present-day clusters of galaxies played an essential role in the evolution of the universe, but are not easy to find. This study shows that a specific type of galaxies, those which emit radiation at submillimetre wavelengths, are very good indicators of the presence of distant protoclusters

The technology which is used in astrophysics research is useful not only in space; many of the sophisticated techniques can be put to very good use in the field of medicine. On this basis in IACTEC there is a team of Medical Technology (TECMED) who develop combinations of the methods of Artificial Intelligence and Machine Learning used in astrophysics for the diagnosis of pathologies. To celebrate the International Day of Diabetes the team stresses the magnitude of the problema in the Islands. Some experts call diabetes one of the worst “silent pandemics”. Spain is the second country in the
