Giant 'forbidden planet' orbiting small star shows an unusually low-metal atmosphere

Scientists have discovered that a highly unusual giant planet—sometimes called "forbidden"—could have an atmosphere with fewer heavier elements than its host star. University of Birmingham astrophysicist Dr. Anjali Piette worked with an international research team to analyze James Webb Space Telescope data from the exoplanet TOI-5205 b. This is a Jupiter-sized planet orbiting a star about four times the size of Jupiter and about 40% the mass of the sun.

Gemini South confirms long-suspected link between the composition of exoplanets and their host stars https://phys.org/news/2026-04-gemini-south-link-composition-exoplanets.html 🪐 #Exoplanet #Exoplanets #AlienWorlds #AlienLife #Extraterrestrials #Space #Science #SolarSystem #Astrobiology

Gemini South confirms long-suspected link between the composition of exoplanets and their host stars

Astronomers have discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was achieved through the first-ever simultaneous measurement of gaseous magnesium and silicon in a planet's atmosphere. The team used the Gemini South telescope, one half of the International Gemini Observatory. The findings are published in the journal Nature Communications.
