A study published today in Nature Astronomy , in which a researcher from the IAC has participated, outlines the discovery of an extremely rare type of binary system composed of two high mass white dwarfs. The two stars are so close together that they will eventually collide resulting in a supernova explosion which, due to its proximity to the Earth, will appear ten times brighter than the Moon. Type 1a supernovae are a class of cosmic explosion often used as "standard candles" to measure the expansion of the Universe. They occur when a white dwarf exceeds the Chandrasekhar mass - the limit

La viceconsejera de Planificación Territorial y Reto Demográfico del Gobierno de Canarias, Elena Zárate Altamirano, ha visitado las instalaciones del IACTEC , en el Parque Científico y Tecnológico de las Mantecas, para conocer de primera mano el proyecto European Solar Telescope (EST). Zárate se ha reunido con el equipo promotor del EST y ha recorrido las instalaciones del centro de tecnología del IAC donde están ubicados algunos de sus laboratorios de instrumentación. En la reunión han participado, entre otros, la directora técnica del proyecto Mary Barreto, la ingeniera civil Yanira

An international scientific team, including members of the Instituto de Astrofísica de Canarias (IAC), has launched an ambitious program to map exoplanets located around the Neptunian Desert —a region around stars where planets the size of Neptune are very rare— in order to better understand the mechanisms of planetary system evolution and formation. This scientific expedition has delivered its first results with the observation of the TOI-421 planetary system. Analysis of this system reveals a surprisingly inclined orbital architecture, offering new insights into the chaotic history of
