Heart-Shaped Valentines, from Nature to You

Mars is red. The ocean is blue. Auroras glow bright, and Pluto loves you, too.

You show your love for geoscience in thousands of tiny ways. Your eyes might light up when you see unexpected geology in the rockface alongside the road. Maybe you can’t help but puzzle over the mineralogy of a handful of sand at the beach. Or you might know obscure trivia about planets and moons and can’t help sharing it with everyone. This Valentine’s Day, celebrate your love of Earth and space science with these naturally heart shaped features that show that the feeling is mutual.
