# Voyager 2's Historic Encounter with the Tilted Ice Giant Uranus

# This is your Astronomy Tonight podcast. Good evening, stargazers! Today is January 24th, and we're celebrating one of the most delightfully quirky anniversaries in astronomical history. On this date in 1986, the Voyager 2 spacecraft made its historic flyby of **Uranus**, giving us our first and—to this day—only close-up images of this tilted ice giant. And when I say "tilted," I mean *tilted*. Uranus rotates on its side at an extreme 98-degree axial tilt, making it the solar system's resident oddball. Scientists still debate whether it got knocked over by a massive collision billions of years ago, or if it was simply born rebellious! Voyager 2 captured stunning images of Uranus's faint ring system and discovered 11 new moons we'd never seen before. It revealed that Uranus has an incredibly active atmosphere with supersonic winds reaching 900 kilometers per hour—despite receiving 400 times less solar energy than Earth! The spacecraft also detected a powerful magnetic field tilted 59 degrees from the planet's rotational axis. Essentially, Uranus is the "wrong side up" weirdo of our solar system, and we love it for that. That distant robotic explorer sent back data that fundamentally changed our understanding of the outer planets, and all from a spacecraft launched way back in 1977!
