Summary

Story summary

NASA researchers have found strong evidence for an atmosphere around the rocky exoplanet TOI-561 b, challenging beliefs about ultra-hot worlds.
James Webb Space Telescope (JWST) observations show TOI-561 b's dayside temperature of 3,200 degrees Fahrenheit.
The planet is about 1.4 times wider than Earth and orbits its star in under 11 hours.
It lies roughly 280 light-years away and may have a global magma ocean.

History

Historical Context

In 1992, astronomers Aleksander Wolszczan and Dale Frail confirmed the first exoplanets orbiting the pulsar PSR B1257+12, demonstrating that planetary systems exist beyond our solar system. This groundbreaking discovery paved the way for future exoplanet research, including the recent findings about TOI-561 b, which has an extreme temperature of 3,200 degrees Fahrenheit, expanding our understanding of exoplanetary atmospheres and potential habitability.
