SpaceTime Series 27 Episode 38
*Witnessing the Final Stages of Planetary Formation
For the first time, astronomers have captured the end of the planetary formation process, observing the dispersal of gas from a young star's circumstellar disk. The James Webb Space Telescope has provided unprecedented images of the Tchar star system, where a vast gap in its disk suggests we're witnessing the final act in its planetary evolution. The study sheds light on the fate of gas giants and terrestrial planets, revealing the delicate dance of creation that shapes nascent solar systems.
*The Devil's Comet: A Green Spectacle in the Sky
Comet 12P/Pons-Brooks, with its distinctive green hue and horned appearance, is making its first visit to the inner solar system in over 70 years. This Mount Everest-sized icy wanderer could grace our skies with its naked-eye visibility as it reaches perihelion this April. Nicknamed the 'Devil's Comet', its cryovolcanic nature promises a celestial show that won't return until 2095.
*The Dust that Doomed Dinosaurs
A new study proposes that fine dust particles from the Chicxulub asteroid impact contributed significantly to the mass extinction event that ended the reign of the non-avian dinosaurs. By blocking photosynthesis and plunging the Earth into a cold, dark winter, this fine dust may have been the final nail in the coffin for many species, reshaping life on our planet forever.
