Dec. 6, 2023 Galactic winds enable the exchange of matter between galaxies and their surroundings. In this way, they limit the growth of galaxies, that is, their star formation rate. Although this had already ...
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 ...
Feb. 22, 2024 Astronomers have characterized a bright quasar, finding it to be not only the brightest of its kind, but also the most luminous object ever observed. Quasars are the bright cores of distant galaxies ...
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 ...
Dec. 21, 2023 While many holiday traditions involve feasts of turkey, soba noodles, latkes or Pan de Pascua, this year, the European Southern Observatory is bringing you a holiday chicken. The so-called Running ...
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 ...
