A year’s monitoring of an ultraluminous pulsar suggests that the emission from the object appears to change and soften due to masking by a surrounding accretion disk.

An attempt to eavesdrop on optical signals from extraterrestrial civilizations found no signals, despite being capable of detecting constant signals of just a few watts.
Steven L. Finkelstein et al 2022 ApJL 940 L55
Using JWST photometry, researchers identified a galaxy with a potential redshift greater than 12; if follow-up spectroscopy confirms this finding, it means galaxies came to be less than 400 million years after the Big Bang.

Researchers detect for the first time X-ray emission from interstellar medium gas swept up by the expansion of Tycho’s supernova remnant — what’s left after a supernova that was observed in 1572.

A new catalog of metal-poor stars in the Milky Way provides targets for studies of nucleosynthesis in the early universe, which can be probed with spectroscopic follow up.

New spectral maps of the surface of the most volcanically active body in the solar system — Jupiter’s moon Io — confirm previous findings that the sulfurous frost on the moon’s surface is stable for decades.
