Mar. 1, 2024 Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international ...
Feb. 29, 2024 Using archival data from the Gemini North telescope, a team of astronomers has measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a ...
Feb. 29, 2024 An international team of astronomers obtained observational evidence for the creation of rare heavy elements in the aftermath of a cataclysmic explosion triggered by the merger of two neutron ...
Feb. 28, 2024 Scientists working with data from NASA's James Webb Space Telescope (JWST) have obtained the first full spectra of some of the earliest starlight in the universe. The images provide the clearest ...
Feb. 22, 2024 NASA's James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a ...
Feb. 22, 2024 Luke Skywalker's childhood might have been slightly less harsh if he'd grown up on a more temperate Tatooine -- like the ones identified in a new study. According to the study's ...
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 ...
Feb. 21, 2024 The supermassive black hole in the center of the Milky Way is spinning so quickly it is warping the spacetime surrounding it into a shape that can look like a football, according to a new study. That ...
Feb. 20, 2024 A few years ago, astronomers uncovered one of the Milky Way's greatest secrets: an enormous, wave-shaped chain of gaseous clouds in our sun's backyard, giving birth to clusters of stars ...
Feb. 16, 2024 Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is a concern. Radioactive waste products can be turned into more stable ...
Feb. 15, 2024 In creating five new isotopes, scientists have brought the stars closer to Earth. The isotopes are known as thulium-182, thulium-183, ytterbium-186, ytterbium-187 and ...
Feb. 15, 2024 If gravitational condensate stars (or gravastars) actually existed, they would look similar to black holes to a distant observer. Two theoretical physicists have now found a new solution to Albert ...
Feb. 8, 2024 For the first time, physicists have captured direct images of 'second sound,' the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' ...
Feb. 7, 2024 Two astrophysicists have finally solved a 20-year-old astrophysical puzzle concerning the lower-than-expected amounts of the element sulphur found in Planetary Nebulae (PNe) in comparison to ...
Feb. 6, 2024 Employing massive data sets collected through NASA's James Webb Space Telescope, astronomers are unearthing clues to conditions existing in the early universe. The team has catalogued the ages ...
Feb. 6, 2024 A carbon monoxide (CO)-runaway gap identified in the atmospheres of Earth-like planets can help expand the search for habitable planets. This gap, identified through atmospheric modeling, is an ...
Feb. 6, 2024 Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data ...
Feb. 1, 2024 Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the Universe was less than a billion years ...
Jan. 31, 2024 The earliest galaxies are thought to have formed as the gravitational pull of dark matter, which has been impossible to study directly, slowly drew in enough hydrogen and helium to ignite stars. But ...
Jan. 31, 2024 Although solar flares have been classified based on the amount of energy they emit at their peak, there has not been significant study into differentiating flares since slow-building flares were ...
