We Don’t Know What the Sun Is Made Of
Unlike Earth, our Sun is a giant ball of mostly hydrogen and helium. Astronomers managed to figure that one out roughly 100 years ago. But after all this time, they still can't come to an agreement on what "mostly" means, precisely.

These Frogs Hide Thanks to Transparent Skin
Hanging out in the trees of Central and South America are some frogs with pretty unusual coloration. Which is to say, parts of them have no color at all. Their bellies are completely see-through!
