New space telescope will reopen astronomers’ view of the far-infrared

AI Insight

NASA is developing PRIMA, a $1.2 billion space telescope designed to observe the far-infrared spectrum, which has been largely inaccessible to astronomers in recent years. The telescope will focus on studying two key areas: the evolution of galaxies and the formation of planets from protoplanetary disks of gas and dust. PRIMA will reopen observational capabilities in wavelengths that are critical for understanding cold cosmic structures and planet-forming environments.

Why it matters

This mission will fill a significant observational gap in astronomy, as far-infrared wavelengths are blocked by Earth's atmosphere and require space-based instruments. Understanding galaxy evolution and planet formation processes has direct implications for comprehending our own solar system's origins and the potential for planetary systems around other stars.
