Webb Telescope Reveals Surprising Atmosphere on Ancient Lava Planet

NASA's JWST has provided the strongest evidence yet that the ultra-hot super-Earth exoplanet TOI-561 b, despite its extreme conditions, possesses a thick, volatile-rich atmosphere, challenging previous assumptions about small, hot planets losing their atmospheres. The findings suggest this planet has retained its atmosphere, possibly due to a balance between atmospheric escape and magma ocean absorption, opening new questions about planetary evolution in harsh environments.

Webb Telescope Discovers Unexpected Atmosphere on Hot Lava Exoplanet

A new study reveals that the ancient exoplanet TOI-561 b, despite its extreme proximity to its star and high temperatures, has retained a thick atmosphere, challenging previous assumptions about hot, rocky planets and suggesting complex interactions between its surface and atmosphere. The planet's unique characteristics, including its low density and potential volcanic activity, are being studied using JWST data, providing new insights into planetary evolution in the early universe.

Webb Telescope Reveals Atmosphere on Lava-Soaked Super-Earth

NASA's James Webb Space Telescope has found strong evidence that the ultra-hot rocky exoplanet TOI-561 b is surrounded by a dense atmosphere above a magma ocean, challenging previous beliefs about small planets close to stars being atmosphere-free. The planet's lower-than-expected density and temperature measurements suggest a volatile-rich atmosphere that persists despite intense stellar radiation, possibly maintained by a balance between atmospheric gases and a magma ocean.
