An international team, including a researcher from the Instituto de Astrofísica de Canarias (IAC), has obtained an incredible image of the planetary nebula NGC 1514 using the James Webb Space Telescope (JWST), revealing the nebula's spectacular dusty rings in unprecedented detail. NGC 1514 was one of the first nebulae to be studied by astronomer William Herschel, who noted that when viewed through his telescope (the biggest in the World at the time) the nebula looked like a fuzzy cloud somewhat similar in appearance to one of his other discoveries: the planet Neptune. The new images acquired

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
