Mengting Ju et al 2026 ApJL 1002 L18 Using data taken with a novel slit-stepping observing mode, researchers have found an anticorrelation between radial metallicity gradients and radial mixing time for galaxies at z ~ 1.
Astronomers using China's FAST radio telescope have discovered a compact hydrogen cloud devoid of visible stars. Containing nearly 500,000 solar masses of neutral hydrogen, it represents one of the strongest candidates yet for an isolated dark galaxy.
An astronomer from the University of Missouri is leading 130 researchers across 62 institutions, including NASA, Caltech, Princeton, and Harvard. The ambitious mission aims to capture an unprecedented view of the early universe.
Astronomers have solved the mystery behind the musical treble clef-shaped radio formation located beyond the Milky Way's Zone of Avoidance. New research confirms that this peculiar cosmic structure is a rare radio phoenix.
The immense mass of the distant El Gordo supercluster challenges cosmological growth models. Researchers suggest this rapid formation could stem from a two-state self-interacting dark matter mechanism.
