Webb Finds a Hidden Atmosphere on a Molten Super-Earth

James Webb Detects Strongest Evidence Yet of an Atmosphere on a Rocky Exoplanet

An ultra-hot rocky exoplanet may be wrapped in a dense atmosphere, defying expectations about what small planets can sustain. Scientists working with NASA’s James Webb Space Telescope have found the clearest evidence so far that a rocky planet beyond our solar system has an atmosphere. Data from the ultra-hot super-Earth TOI-561 b indicate that the [...]

Scientists Find the Strongest Evidence Yet of an Atmosphere on a Molten Rocky Exoplanet

Researchers using NASA’s James Webb Space Telescope have detected the strongest evidence yet for an atmosphere on a rocky planet outside our solar system. Observations of the ultra-hot super-Earth TOI-561 b suggest that the exoplanet is surrounded by a thick blanket of gases above a global magma ocean.

Webb finds a hidden atmosphere on a molten super-Earth

Webb’s latest observations reveal a hellish world cloaked in an unexpected atmosphere: TOI-561 b, an ultra-hot rocky planet racing around its star in under 11 hours. Despite being blasted by intense radiation that should strip it bare, the planet appears to host a thick layer of gases above a global magma ocean, making it far less dense than expected.

Webb Telescope Detects Atmosphere on Molten Super-Earth TOI-561 b

In a significant advancement for exoplanet science, the James Webb Space Telescope has provided the most compelling evidence to date of an atmosphere surrounding a rocky world. This monumental discovery concerns TOI-561 b, an ultra-hot super-Earth approximately 275 light-years from our solar system. TOI-561 b is characterized by its small size, about 1.4 times Earth’s radius, and its incredibly tight orbit around a Sun-like star, completing a fu…
