When two neutron stars merge, the merger remnant can have a strong enough magnetic field to affect the properties of the matter and change the mechanisms of jet and wind launching.
Barnard Crater on Mars appears to have formed about 3.8 billion years ago and shows signs of sustained periods of infill, resulting in an infilled thickness of 1 kilometer on the crater floor.
Nine unidentified Fermi–Large Area Telescope sources are likely pulsar wind nebulae; if verified, these discoveries will bring the number of known Fermi-detected pulsar wind nebulae from 12 to 21.
Diving deep into various instrumental systematics and data analysis options, a research team has found that the purported detection of biosignature gases in the atmosphere of K2-18b is disfavored.
An investigation of the evolution of fast radio bursts with redshift found similarities in the properties of fast radio bursts and short gamma-ray bursts, suggesting that fast radio bursts might arise from magnetars.
A galactic superwind appears to be the source of two giant bubbles stretching thousands of light-years from the center of a starburst galaxy, though an active galactic nucleus could also be the cause.
