After the New Horizons spacecraft flew by Pluto in 2015, astronomers were surprised by data suggesting ice volcanoes there. Now, new research has found supporting evidence of cryovolcanoes.

The location of the frozen water on Pluto's surface that are a colour we don't normally associate with water or ice: red. Though these cool volcanoes aren't quite like the ones we see here on Earth, they do have some similarities. Another is by tidal heating, where a moon goes around a planet in an elliptical orbit. Due to the difference in distances, the moon can be squeezed, much in the same way one might squeeze a stress ball, which in turn creates heating. This is seen in some ofImage of Saturn's moon, Enceladus, showing the 'tiger stripes,' long fractures from which the water vapor jets are emitted.
