Jupiter's 'dramatic' features from NASA's Juno mission wow the internet and space enthusiasts.

NASA recently extended the life of two of its planetary discovery missions, including the Juno mission to Jupiter.

Now it's come to light Juno has discovered an FM signal emanating from one of the gas giant's moons, Ganymede.

The spacecraft, which launched in 2011, happened to be traveling across Jupiter's polar region at a speed of 111,847 mph when it crossed the radio source, known as a "decametric radio emission," or simply Wi-Fi.

According to NASA, the decametric radio waves have frequencies between 10 and 40 MHz, but never above 40 MHz.

Scientists have known about radio waves on Jupiter since the mid-1950s, but this is the first time the phenomenon has ever been seen emanating from Ganymede.

In 2018, researchers observed "extraordinary" electromagnetic waves, also known as "chorus waves," thanks to the Galileo Probe spacecraft.

Juno has made a number of discoveries about Jupiter, including capturing remarkable, never-before-seen images, as well as a "snow-white" oval storm.
