"Unraveling the Mystery: Astronomers Investigate an Enigmatic Exoplanet's Fiery Nature"

Astronomers have studied the scorching exoplanet WASP-76 b using the MAROON-X instrument on the Gemini-North Telescope, identifying 11 chemical elements in its atmosphere. The findings suggest that the planet's composition reflects that of the protoplanetary disc from which it formed, and its extreme temperatures cause rock-forming elements to vaporize. The absence of certain elements requiring higher temperatures to vaporize suggests that WASP-76 b may have swallowed material from a Mercury-like planet. The study provides crucial insights into the formation and composition of giant planets.
