Tuesday, 3 April 2018 () The blistering blue star, which existed almost 10 billion years ago, was imaged thanks to a chance alignment that magnified it by a factor of at least 2,000. In a study published today in Nature Astronomy, an international team of researchers announced the discovery of the most distant star ever observed. The team detected the blue supergiant star — which shone when the universe was just one-third its current age — with the help of both the Hubble Space Telescope and an observational phenomenon known as gravitational lensing. “This is the first time we’re seeing a magnified, individual star,” said Patrick Kelly, an astrophysicist of the University of Minnesota...
