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.

Each of the studied outbursts released roughly one hundred thousand to one million kilograms of material — similar to outbursts from other comets — and caused brightening episodes of –0.2 to –1.1 magnitudes.

Using high-cadence ultraviolet observations of solar flares over the course of 12 years, researchers have carried out a statistical survey that revealed rapid pulsation of small-scale flare structures.

Dwarf elliptical galaxies in the Virgo Cluster appear to come in “flat” and “round” varieties; the dynamics of these populations suggest that flat dwarf ellipticals have experienced less tidal processing.

Analysis of Cassini spectra of Titan suggests that JWST is unlikely to identify atmospheric components aside from methane on a Titan-like exoplanet; optical and near-ultraviolet observations will be key.

A concentration of galaxies four times denser than expected provides an opportunity to understand how environment impacts galaxy evolution and the onset of reionization.
