Drifting pebbles deliver water to the inner regions of planet-forming disks How are planets born? Scientists have long proposed that ice-covered pebbles are the seeds of planet formation. These icy solids are thought to drift toward the newborn star from the cold, outer reaches of the disk surround

Scientists using NASA s James Webb Space Telescope just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, Webb confirmed a physical p
Water vapor observed sublimating from tiny chunks of rock within planet-forming disks is a sign that a process called "pebble accretion" kickstarts the birth of new worlds.
