What the Luminous Red Nova Remnant Looks Like, Revealed by JWST
Introduction: A Stellar Collision’s Quiet Aftermath When two stars collide and merge, they can briefly erupt as a luminous red nova, a dramatic transient that outshines typical novae but fades more quickly than supernovae. For years, astronomers have studied these rare events to understand how stellar mergers reshuffle a star’s destiny. The James Webb Space…

Webb’s Revelation: Young Sun-like Star Forging Crystals in Its Outer Disk and Ejecting Them toward Comets
Introduction: Unveiling Crystalline Mysteries at the Edge of a New Solar System For decades, scientists have puzzled over a surprising feature in comets: crystalline silicates, crystals that form only under intense heat. These solid gems, found in the cold depths of the outer solar system, have long hinted at dramatic early processes in planetary systems.…

Webb Detects Crystalline Silicates Flinging from a Young Sun-like Star into Its Outer Disk
Webb unveils a surprising mechanism in a young star’s disk In a landmark discovery, NASA’s James Webb Space Telescope (Webb) has observed a young, sun-like star actively forging crystalline silicates and ejecting them into its surrounding outer disk. This finding offers a fresh perspective on how the crystals that later appear in comets might form…
