Lava planet has hydrogen-rich, active atmosphere
Researchers using the James Webb Space Telescope have analyzed the atmosphere of the super-Earth exoplanet 55 Cancri e. The findings suggest the planet is a lava world with an atmosphere rich in carbon monoxide and hydrogen, likely shaped by extreme heat from its host star.
Why it matters
Understanding the composition of lava planets provides critical insights into the formation and evolution of rocky planets outside our solar system.
It’s 2158, and you’re chugging away on your PhD in Planetary Volcanology from the University of Utopia Planitia on Mars. Graduate students still get paid a sub-living wage, so you’ve been stuck eating freeze-dried ramen for the past three years. You’ve completed studying Jupiter’s moon, Io, but now you have to leave the solar system for a good exoplanet analog. While Io’s volcanism is caused by tidal heating, you need an exoplanet whose volcanism is caused by extreme heat from its host star. You recently secured funding from the Exoplanet Research Institute for a faster-than-light (FTL) ship, but the exoplanet is required to be less than 50 light-years away.
