Jupiter's main ring was discovered in 1979 by NASA's passing Voyager 1 spacecraft, but its origin was then a mystery. Data from NASA's Galileo spacecraft, however, that orbited Jupiter from 1995 to 2003 confirmed the hypothesis that this ring was created by meteoroid impacts on small nearby moons.

Wind speeds peaked at 260 km/h, the equivalent of a category 5 hurricane on NOAA's scale. ESA astronaut Alexander Gerst captured the eye of the massive storm from the International Space Station.

What at first appears to be a single, strangely shaped galaxy is actually two galaxies that are separated by a large distance. The closer foreground galaxy sits at the center of the image, while the more distant background galaxy appears to be wrapped around the closer galaxy, forming a ring. Credit: ESA/Webb, NASA & CSA, G.
