(1) New thinking towards Star Formation:- "Unlocking Cosmic Mysteries: Webb's Neon Sign Journey Reveals Surprises in Planet Formation" Scientists, led by astronomer Catherine Espaillat of Boston University, are unraveling the secrets of planet formation by following neon signs in the cosmos. Building on peculiar readings from NASA's retired Spitzer Space Telescope, the James Webb Space Telescope has identified distinctive traces of neon around the young Sun-like star SZ Chamaeleontis (SZ Cha). Discrepancies in neon readings between the two telescopes suggest an unprecedented shift in high-energy radiation impacting the star's dusty disk, influencing the timeline for planet formation. The study delves into the cosmic history of SZ Cha, a T-Tauri star akin to our Sun 4.5 billion years ago. Neon serves as a key indicator of radiation influencing the star's disk, crucial for understanding the formation of planets. In 2008, Spitzer detected an anomaly in SZ Cha...
