A planet 320 light-years away confirms what scientists long suspected

Astronomers have discovered that a scorching-hot planet 320 light-years away shares a striking chemical similarity with its host star, providing the first direct evidence for a fundamental assumption about planet formation. The breakthrough could help scientists predict what distant rocky planets are made of and identify worlds with conditions favorable for life.

A planet 320 light-years away confirms what scientists long suspected Science News from research organizations A planet 320 light-years away confirms what scientists long suspected A scorching-hot planet 320 light-years away has confirmed a long-held assumption about planet formation, offering a powerful new clue in the search for habitable worlds. Pollard A scorching hot planet nearly 320 light-years from Earth has provided the first direct evidence for a fundamental assumption about how planets form. Astronomers discovered that WASP-189b shares an important chemical characteristic with its host star, supporting a long-standing idea that also helps scientists investigate potentially habitable worlds.

The breakthrough came from the first simultaneous measurement of gaseous magnesium and silicon in an exoplanet’s atmosphere, using the Gemini South telescope, part of the International Gemini Observatory, which is partially funded by the U.S. National Science Foundation and operated by NSF NOIRLab. Located nearly 320 light-years away in the Libra constellation, WASP-189b belongs to an extreme category of planets called ultra-hot Jupiters (UHJ).

These enormous worlds reach temperatures so intense that even materials normally found in solid rock can turn into gas.
