NASA's James Webb Space Telescope has identified "extreme debris disks" around 21 young star systems, offering new insights into the formation of terrestrial planets. These disks contain warm dust, including glassy silica from energetic impacts between Mars-sized objects and forsterite from smaller collisions. The findings illuminate the tumultuous final stages of planet formation, akin to the event believed to have formed Earth's Moon.
NASA is advancing the design for its Probe Far-infrared Mission for Astrophysics (Prima), a new space telescope aimed at observing the cold, dusty universe. Prima will explore a far-infrared wavelength band currently unobserved by existing telescopes, potentially offering a thousand-fold increase in sensitivity for studying newborn stars, black holes, and planet-building materials. A final agency review is pending, with a potential launch in the early 2030s.
