TOI-5205 b is a Jupiter-sized planet orbiting a star less than half the mass of our Sun. A planet so unlikely that astronomers call it "forbidden." Now, a team including Carnegie's Shubham Kanodia has found that it's even weirder than we thought.

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 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.

A planet similar to Earth near a sunlike star.

Most of the billions of stars in our galaxy likely have planets. Researchers at Cornell University in Ithaca, New York, say they have identified 45 rocky worlds - out of the 6,100 #exoplanets known so far - that are most likely to be potentially habitable. 🌌🔭

Venn diagrams of detection significance of CO, H2S, non-gray clouds, and non-isothermal temperatures using combinations of NIRISS, NIRSpec, and MIRI (and WFC3 as a replacement of NIRISS).

Ooo I quite like these plots, showing how well you detect things in an exoplanet (HAT-P-12b) spectrum with JWST (and HST) using combinations of instruments.
