"Vanishing Atmospheres: TRAPPIST-1 System's Disappearing Gases"

A new study suggests that the Trappist-1 system's planets are likely barren and stripped of their atmospheres, making the existence of life in the system unlikely. The study indicates that the intense radiation from the system's red dwarf star has likely caused the planets to lose their atmospheres at a rapid rate, rendering them warm, dry rocks. This finding has significant implications for the potential habitability of planets orbiting red dwarf stars, which make up a large portion of the stars in our galaxy.

"Unveiling Cosmic Fury: Hubble Captures Angry Star and Vanishing Planet"

NASA's Hubble Space Telescope has provided new insights into the interaction between a red dwarf star named AU Microscopii and its planet, AU Microscopii b. The star's high-energy radiation is causing the planet's atmosphere to evaporate, resulting in a shedding of planetary material. This observation is significant because it is the first time scientists have witnessed such shedding on a regular planet, providing important insight into atmospheric escape during the formative period of exoplanetary systems. The findings could help scientists understand the evolution of exoplanets and the commonalities and differences between young red dwarfs and other stars.
