A newly discovered extremely red object dubbed Cerberus likely lies outside our galaxy, most likely at a redshift of z ~ 4 or, remarkably, at an extremely high redshift of z ~ 15.
Using detailed kinetic simulations, researchers explored the development of nonlinear mirror modes in intracluster medium plasma; nonlinear mirror modes can trigger bursts of whistler waves called lion roars.
If the streaming instability is responsible for creating 100-km “moonlets” that then coalesce to form the Moon, the disk from which this material originated must have been vapor poor rather than vapor rich.
There are significant differences between multi-armed spiral galaxies and two-armed “grand design” spiral galaxies, including stellar mass, half-light radii, and central bulge properties.

Detailed measurements of chemical abundances in the atmospheres of cool, low-mass stars reinforce the theory that star formation in globular clusters proceeds in a series of bursts.
A review of 51 X-ray bursts from a prolific Milky Way magnetar — the source of the first fast radio burst to be associated with an X-ray burst — reveals the object’s spectral evolution.
