Gleaming white radio dishes point up to the starry abyss and receive radio emissions of the cosmos. It's just how we interpret what we hear is the fun part!

From planets, rapidly spinning stars, or even black holes, radio astronomy is almost like a hidden gem when it comes to space discoveries!

Our recently decommissioned Cassini spacecraft had a radio wave science instrument. When it got to within 234 million miles on way to Saturn, it started to pick up very interesting hissing and tonal emissions! Guess what they are?! These are the sounds of Saturn's powerful polar aurorae (northern and southern lights)!

These sounds were compared to Earth's auroral radio emissions, which can be listened here (warning: audio is a bit loud).

Very different, right? Aurorae are still being studied on Saturn and Jupiter thanks to the large amounts of data collected by the Cassini spacecraft!

Thanks for reading, and next week we'll take a look at the Martian Moons!
