Jan. 21, 2025 — Fast radio bursts are mysterious and brief flashes of radio emissions that were thought to be produced by magnetars, highly magnetized rotating neutron stars. Yet magnetars appear primarily in young ...
Jan. 21, 2025 — Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive stars. But new FRB is pinpointed to the outskirts of 11.3-billion-year-old galaxy without young, active stars -- calling those ...
Jan. 17, 2025 — The Universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous -- and highly debated -- results had shown: The Universe is expanding faster than predicted by ...
Jan. 17, 2025 — In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way -- the magnificent ...

Jan. 16, 2025 — In 2018, a galaxy about 270 million light-years away from Earth exhibited a major increase in activity. It quieted down again by 2020 -- only to ...
Jan. 15, 2025 — A new analysis of data from the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) reveals fresh evidence that collisions of even very small nuclei with large ones might create tiny ...
Jan. 15, 2025 — By combining data from the DESI Legacy Imaging Surveys and the Gemini South telescope, astronomers have investigated three ultra-faint dwarf galaxies that reside in a region of space isolated from ...
Jan. 15, 2025 — For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don't go looking for it -- the flickering star is 2.2 million ...
Jan. 15, 2025 — Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...
Jan. 15, 2025 — New observational data and simulation models have confirmed a new type of planet unlike anything found in the Solar System. This provides another piece of the puzzle to understand how planets and ...
Jan. 15, 2025 — Hot Jupiters are giant planets initially known to orbit alone close to their star. During their migration towards their star, these planets were thought to accrete or eject any other planets present. ...
