The European Space Agency’s Euclid mission released its first batch of survey data, including a preview of its deep fields. Using Artificial Intelligence (AI) algorithms in combination with citizen science campaigns, the Euclid Consortium scientific results include the discovery of strong gravitational lensing systems, the exploration of galaxy clusters and the cosmic web, the characterisation of active galactic nuclei (AGN) and quasars, studies on galaxy evolution and morphology, and the identification of numerous dwarf galaxies and transients. Spain has an important role in the Euclid

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

The Technical Office for the Protection of the Quality of the Sky (OTPC) of the IAC is collaborating to advise about the implementation of energy efficiency and the reduction of light pollution in the port installations of general interest which belong to the public company Puertos Canarios. Specifically, the IAC has just issued a report which checks out the exterior lighting of the installations of the Port of las Nieves in Agaete (Gran Canaria), and in the coming months expects to carry out suitable tests in the Port of Vueltas in Valle Gran Rey (La Gomera) and the Port of Garachico
