Nov. 30, 2021 Astronomers have revealed the closest pair of supermassive black holes to Earth ever observed. The two objects also have a much smaller separation than any other previously spotted pair of ...
Mar. 2, 2022 In 2020, astronomers reported the closest black hole to Earth, located just 1000 light-years away in the HR 6819 system. But the results of their study were contested by other researchers. In a new ...
Oct. 31, 2022 A beautiful tapestry of colors, showing the ghostly remains of a gigantic star, was captured in incredible detail with the VLT Survey Telescope, hosted at the European Southern Observatory's ...
Nov. 15, 2023 ALMA (Atacama Large Millimeter/submillimeter Array) has demonstrated the highest resolution yet with observations of an old star. The observations show that the star is surrounded by a ring-like ...
Aug. 5, 2022 According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull ...
Mar. 8, 2021 Astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a 'radio-loud' quasar -- a bright object with powerful jets emitting ...
Sep. 22, 2022 Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have spotted signs of a 'hot spot' orbiting Sagittarius A*, the black hole at the centre of our galaxy. The ...
Mar. 8, 2022 Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest ...
Sep. 6, 2023 Astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years ...
Oct. 19, 2023 An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was ...
