Mon Jan 27 03:30:00 UTC 2025: ## Supersonic Winds Discovered on Distant Exoplanet
**Munich, Germany – January 27, 2025** – Astronomers have discovered the fastest planetary winds ever recorded on an exoplanet named WASP-127b. Located 520 light-years from Earth, this “hot Jupiter” boasts supersonic jet streams reaching an astonishing 33,000 kilometers per hour – far exceeding even Neptune’s high-speed winds.
The findings, published in *Astronomy & Astrophysics*, were made by an international team led by Lisa Nortmann of the University of Göttingen. WASP-127b, a gas giant significantly larger than Jupiter but with only 16% of its mass, orbits its star incredibly closely, completing a revolution every four days. This proximity results in extreme temperatures, reaching approximately 1,127 degrees Celsius on its day side, which perpetually faces its star. The study also confirmed the presence of carbon monoxide and water in WASP-127b’s atmosphere.
The researchers believe the intense stellar radiation from the star is the primary driver of these supersonic winds, although other factors likely contribute to the planet’s unique atmospheric dynamics. While faster wind speeds have been detected on other exoplanets, none have been observed encircling the entire planet at such a velocity. This discovery provides valuable insights into the atmospheric processes on gas giants orbiting close to their stars and offers further understanding of exoplanetary weather systems.
