Supersonic Winds Are Ripping Through This Exoplanet at Record-Breaking Speeds

  • The farthest planet from the Sun, Neptune, is the windiest place in the solar system, with winds that whip through at speeds reaching more than 0.3 miles per second (0.5 kilometers per second). That's a relatively pleasant wind speed compared to a giant, puffy planet located around 500 lightyears away from Earth.

The article from Gizmodo discusses a groundbreaking discovery about the exoplanet WASP-107b, where astronomers have observed supersonic winds traveling at speeds of up to 1,300 miles per hour (2,100 kilometers per hour). This phenomenon was detected using the Hubble Space Telescope, which analyzed the light passing through the planet's atmosphere during its transit across its host star. The high-speed winds are believed to be caused by the extreme temperature differences between the star-facing side and the opposite side of the planet, leading to a massive transfer of heat and material across the planet. This discovery not only provides insights into the atmospheric dynamics of exoplanets but also marks the first time such supersonic winds have been observed on a planet outside our solar system, offering a new understanding of how weather systems might operate on distant worlds.
