"James Webb Space Telescope Uncovers Vanishing Neon in Newborn Star's Surroundings"
The James Webb Space Telescope has made its first discovery by observing a planet-forming disk around a young star. The observations suggest that the amount of ionized neon gas in these disks can indicate how quickly planets must form before the disk disappears. The presence of doubly ionized neon in the disk initially implied that extreme ultraviolet (EUV) radiation was dominant, but the recent observations show that X-ray radiation has become the dominant radiation field. This finding could have significant implications for understanding the timescale in which planets form before their birthing disk dissipates. Further studies are planned to gather more information and investigate the fluctuations in the stellar wind.
