An international team of researchers, including staff from the Instituto de Astrofísica de Canarias (IAC), has discovered a planetary nebula that destroyed its own planetary system, conserving the remaining fragments in the form of dust orbiting its central star. To date, more than 5000 exoplanets have been discovered orbiting stars of all kinds and almost every stage of stellar evolution. However, while exoplanets have been discovered around white dwarfs – the final stage in the evolution of low- and intermediate-mass stars like the Sun, no exoplanets have been detected in the previous

The Museo de la Ciencia y el Cosmos, part of the Organismo Autónomo de Museos y Centros del Cabildo de Tenerife, will host a conference by the astrophysicist and 2006 Nobel Laureate in Physics, John Mather, entitled ‘Unsolved mysteries of physics and astronomy’, on Friday 9th May. Mather receives this week the recognition as Doctor Honoris Causa of the Universidad de La Laguna (ULL) with the sponsorship of the researcher of the Instituto de Astrofísica de Canarias (IAC) and Doctor Honoris Causa of the ULL, John Beckman. Mather's lecture, which will be in English, will be presented by the

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
