Webb Telescope Obtains Sharpest Surface Data of Rocky Exoplanet LHS 3844 b
Why it matters
First spotted by the Transiting Exoplanet Survey Satellite (TESS) in 2018, LHS 3844 b is a terrestrial world with an 11-hour orbit, leaving it tidally locked. Its permanent day and night sides reflect a lack of a significant atmosphere. Webb utilized mid-infrared spectroscopy to measure thermal emissions, helping researchers pinpoint surface compositions like basalt or volcanic rock.
The study moves astronomy beyond simple planet detection into detailed surface characterization. While Kua'kua’s extreme heat rules out habitability, the methodology provides a template for future missions seeking life-sustaining conditions on cooler, Earth-sized worlds.
Glossary
Exoplanet: A planet that orbits a star outside our solar system.
Tidally Locked: A state where an orbiting body keeps one face permanently directed toward its host star.
