Today is the equinox, when the Sun is directly over the equator. Did you know other planets have seasons and equinoxes, too? On Saturn, they happen only once about every 15 Earth years. This view of an equinox in 2009 came from our Cassini spacecraft. https://solarsystem.nasa.gov/resources/658/the-rite-of-spring/ #NASASolarSystem
Of the countless equinoxes Saturn has seen since the birth of the solar system, this one, captured here in a mosaic of light and dark, is the first witnessed up close by an emissary from Earth … none other than our faithful robotic explorer, Cassini.
