Astronomers conduct one of the most detailed studies of a stellar halo
An international team of astronomers has used the Subaru Telescope to probe the stellar halo of the nearby Messier 81 (M81) galaxy. The observations resulted in one of the most detailed studies of a stellar halo conducted to date. The study is detailed in a paper published October 31 on arXiv.org.

Galaxy found to float in a tranquil sea of halo gas
Using one cosmic mystery to probe another, astronomers have analyzed the signal from a fast radio burst, an enigmatic blast of cosmic radio waves lasting less than a millisecond, to characterize the diffuse gas in the halo of a massive galaxy.

Moon halo over Magellan telescope
This sort of halo is called a 22° halo by skywatchers. You can see them around both the sun and moon. They’re caused by ice crystals in the air. The bear that name because the radius of the ring is always approximately 22°. Source: https://earthsky.org/todays-image/photo-moon-halo-magellan-telescope-chile…
When our Milky Way merged with an ancient dwarf galaxy
Analysis of measurements via the Gaia space telescope – of star positions, brightnesses and distances – has let astronomers probe a merger 10 billion years ago between the primitive Milky Way and a dwarf galaxy called Gaia-Enceladus.

Radio halo detected in the galaxy cluster PSZ2 G099.86+58.45
Using the LOw Frequency ARray (LOFAR), astronomers have probed PSZ2 G099.86+58.45, one of the densest cluster of galaxies known to date. The study revealed the presence of a radio halo in this cluster, making it one of the most distant such features ever discovered. The finding is detailed in a paper published July 24 on arXiv.org.
