Sep. 13, 2023 One of the most interesting and important questions in cosmology is, 'How much matter exists in the universe?' An international team has now succeeded in measuring the total amount of ...
Sep. 13, 2023 These new detections suggest polar ring galaxies might be more common than previously ...
Sep. 12, 2023 At the center of every galaxy is a supermassive black hole. Beyond a certain size, these become active, emitting huge amounts of radiation, and are then called quasars. It is thought these are ...
Sep. 11, 2023 As the universe evolves, scientists expect large cosmic structures to grow at a certain rate: dense regions such as galaxy clusters would grow denser, while the void of space would grow ...
Sep. 11, 2023 A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and ...
Sep. 11, 2023 Elusive fundamental particles called neutrinos are predicted to interact unexpectedly with photons under extreme ...
Sep. 8, 2023 A new article hints at the existence of several black holes in the Hyades cluster -- the closest open cluster to our solar system -- which would make them the closest black holes to Earth ever ...
Sep. 7, 2023 Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it ...
Sep. 7, 2023 New research has revealed the distribution of dark matter in never before seen detail, down to a scale of 30,000 light-years. The observed distribution fluctuations provide better constraints on the ...
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 ...
Sep. 5, 2023 The immense bubble is 820 million light years from Earth and believed to be a fossil-like remnant of the birth of the ...
Aug. 31, 2023 NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A ...
Aug. 31, 2023 While astrophysicists previously believed that only supernovae could generate long gamma-ray bursts (GRBs), a 2021 observation uncovered evidence that compact-object mergers also can generate the ...
Aug. 30, 2023 With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the ...
Aug. 24, 2023 Using ESO's Very Large Telescope (VLT), astronomers have observed a large dark spot in Neptune's atmosphere, with an unexpected smaller bright spot adjacent to it. This is the first time a ...
Aug. 21, 2023 New research has improved the accuracy of the parameters governing the expansion of the Universe. More accurate parameters will help astronomers determine how the Universe grew to its current state, ...
Aug. 17, 2023 Magnetars are the strongest magnets in the Universe. These super-dense dead stars with ultra-strong magnetic fields can be found all over our galaxy but astronomers don't know exactly how they ...
Aug. 15, 2023 In a new study, researchers have taken an important step toward understanding how exploding stars can help reveal how neutrinos, mysterious subatomic particles, secretly interact with ...
Aug. 9, 2023 NASA's James Webb Space Telescope has followed up on observations by the Hubble Space Telescope of the farthest star ever detected in the very distant universe, within the first billion years ...
Aug. 3, 2023 New research details the discovery of the highest-energy light ever observed from the sun. The international team behind the discovery also found that this type of light, known as gamma rays, is ...
