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.

Using light curves from the Transiting Exoplanet Survey Satellite (TESS), researchers have performed an asteroseismic analysis of 221 main-sequence and subgiant solar-like oscillators.

Sunrise III, a stratospheric balloon-borne solar observatory, took a 6.5-day flight from northern Sweden to northwestern Canada in 2024, gathering 200 TB of data with its 1-meter telescope and three instruments.

A recently identified opaque feature around the dwarf planet Quaoar appears to be inconsistent with an orbiting sharp-edged arc explained by triangular-point confinement; it’s likely a satellite instead.
