JWST Unveils Clues to Solar System’s Past Through Distant Trans-Neptunian Objects

Quick Summary

• Trans-Neptunian objects (TNOs) in the Kuiper Belt are ancient icy minor planets dating back to the solar system’s formation.
• researchers from the University of Central Florida (UCF), using NASA’s James Webb space Telescope, identified methanol traces on TNO surfaces.
• Methanol acts as a chemical time capsule, revealing evolutionary changes on these icy worlds over billions of years.
• Surface methanol is depleted due to irradiation but remains preserved in subsurface reservoirs.
• These findings enhance understanding of TNOs and inspire further research into their origins and development.
• The study was published in The Astrophysical Journal Letters.
