Researchers have discovered a supernova that occurred when the universe was roughly 5 billion years old; if the supernova’s luminosity is similar to that of nearby events, it must have been magnified by a factor of 250.

Of 7,229 flares from 1,430 stars, most came from stars with temperatures below 4000K and rotation periods shorter than 4 days; most flares lasted less than 2 hours.

An analysis of the fourth gravitational wave catalog supports the existence of a gap at 45 solar masses in the secondary black hole mass distribution, among other findings.

According to calculations, in a 4-year period researchers may detect of order one compact binary system in which the binary’s inspiral and the spin of its neutron star component both produce gravitational waves.

Unlike traditional “shift and stack” algorithms, a newly developed asteroid-detection method requires no assumptions on speed or direction; this method can be applied to upcoming time-domain surveys.

Researchers show that the global martian dust storm in Mars year 34 warmed the lower atmosphere and led to greater electrical charging and stronger electric fields compared to a dust-free atmosphere.
