New study revises our picture of the most common planets in the galaxy
Research led by UChicago's Eliza Kempton finds some 'mini-Neptunes' likely have solid surfaces rather than molten interiors 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.
