Exoplanets, -moons, -comets Status Report astro-ph.EP November 7, 2025 The number of planets meeting or exceeding an equivalent ring thickness threshold of 0.3651 meters, or the approximate Saturn ring thickness

A new study finds that many “mini-Neptunes”—perhaps the most common planets in the galaxy—are under so much pressure from their heavy atmospheres that the surface is likely compressed solid. Illustration

Comparison of Arctic Ocean FSLE snapshots from the two simulations during March. Brighter regions (high FSLE) indicate more vigorous horizontal stirring. Left panel: present-day conditions; right panel: future conditions representing

The NIRC2 image of dust around a young star named HD34282 (left) produced using an algorithm to construct images from aperture masking interferometry data. The light from the star is

Experimental characterization and structural analysis of designed ancestral proteins. (A) Schematic representation of the design workflow for ancestral proteins. (B) Summary table reporting general features of the selected designs and

C/O ratio as a function of metallicity as given in Table 4. Planets observed with direct spectroscopy are shown as blue circles, planets observed with eclipse spectroscopy as magenta
