Hubble, Webb Telescopes Observe Distant Solar System Objects

VERA Brief

AI-generated. Grounded in the article and its cited sources.

NASA's Hubble and James Webb Space Telescopes have jointly studied Trans-Neptunian Objects (TNOs) for the first time, observing some of the smallest and faintest directly. The findings suggest fewer small TNOs than anticipated, which could refine models of solar system formation and evolution.

Key facts

• NASA's Hubble and James Webb Space Telescopes have jointly studied Trans-Neptunian Objects (TNOs) for the first time.
• The observation campaign focused on some of the smallest and faintest TNOs ever directly detected.
• Researchers reported a lower quantity of small TNOs than models had predicted.
• The study aims to refine models of solar system formation and evolution.
