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 Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) has confirmed the discovery of a super-Earth orbiting in the habitable zone of HD 20794, a nearby Sun-like star. This discovery, the result of over two decades of observations, opens a window to future studies of Earth-like planetary atmospheres. The search for planets in the habitable zone of Sun-like stars is crucial for understanding the possibility of life beyond Earth and for studying conditions similar to those that enabled the development of life on our own planet. In this context, HD 20794, a star

The Instituto de Astrofísica de Canarias has put itself on the frontier of astrophysical technology by developing the first integrated photonic circuit designed entirely within the Institute. This pioneering advance will permit the improvement of astronomical instruments, and the development of innovative systems for observing the universe. Astrophysical instrumentation, for both ground-based and space-based use is so specialized that often comercial systems and subsystems do not come up to the required specifications, This makes it necessary to buy high priced components or to delegate
