A neutrino detector in Antarctica has found heaps of high-energy neutrinos coming from distant galaxies, but none from within our own – until now
Scientists at Brookhaven National Laboratory have used two-dimensional condensed matter physics to understand the quark interactions in neutron stars, simplifying the study of these densest...

However , the mergers between
A pair of astrophysicists, one with Princeton University, the other the University of Maryland, has developed a new theory to explain fast radio bursts (FRBs). In their paper published in the journal Physical Review Letters, Elias Most and Alexander Philippov, describe their theory and how it fits in with other theories surrounding FRBs.
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a team of Chinese astronomers has detected a new millisecond pulsar in the globular cluster Messier 53. The finding is reported in a research paper published June 16 on the pre-print server arXiv.
Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively explain the many intricate physical and cosmological phenomena observed over the past decades.
We know there are stars moving fast enough to escape the Milky Way, so the same is probably true of other galaxies. Now, simulations suggest there could be almost 4000 stars from the Andromeda galaxy in the Milky Way today
