Scientists Say: Gas giant
These gargantuan planets, such as Jupiter and Saturn, are mostly made up of hydrogen and helium gas.
- Brain
Curiosity drives this neuroscientist and artist
Christine Liu studies the brain on nicotine — and used Instagram to bring together women doing incredible science.
- Earth
Scientists Say: Glacier
