Astronomy editors updated a comprehensive exoplanet guide Saturday alongside research suggesting planets could form in extreme environments near supermassive black holes.
Thousands of confirmed worlds already catalogued around ordinary stars provide templates for mass, radius and atmospheric composition.
New simulations propose that dense disks around active galactic nuclei might briefly host rocky embryos before intense radiation strips atmospheres.
Observers rely on transit and radial-velocity methods to detect worlds far beyond our solar neighborhood.
Upcoming space telescopes aim to spectroscopically analyze habitable-zone planets for water vapor and carbon dioxide signatures.
Scientists cautioned that black-hole formation scenarios remain speculative until instruments can survey those distant regions directly.
