Record-Shattering 20,000 Mph Winds Detected on Wild Alien Planet
Here on Earth, the fastest puff of wind on record was a blustery 407 kilometers (253 miles) per hour, measured on Australia's Barrow Island in 1996. Neptune has the highest wind speeds in our Solar System, but even its 1,770 kilometer-per-hour high-altitude currents feel more like a mild breeze by comparison.
