Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of any known objects, […]

A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into each cubic parsec. The team […]

A new study by researchers at the SETI Institute suggests that stellar “space weather” could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma turbulence near a transmitting planet can broaden […]

As a space scientist, every time I go outside with my family, I tell my children to look up at the sky. The front door of our home looks southeast, and on winter nights the […]

Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster known as NGC 2158. Results of the study, published Feb. 25 on the arXiv pre-print server, provide […]

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of […]

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing estimates of the universe’s age […]

When most people think of a supernova, they’re thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They’ve used up their […]

What happens when a solar superstorm hits Mars? Thanks to the European Space Agency’s Mars orbiters, we now know: glitching spacecraft and a supercharged upper atmosphere.This post was originally published on this site

For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo surrounding the Geminga pulsar wind nebula (PWN). This observation […]
