We’ve done a surprising amount of exploration on Mars, from its atmosphere, to its surface, and miles deep into its canyons. But mapping its insides has been a quandary that we hadn’t been able to solve until last week!

If you’ve been brave enough to open your eyes underwater, you might have noticed that everything is blurry. But fish have no trouble finding their way beneath the waves. So why can’t we see as clearly below as we do above?

Hank pretends he has an invisibility cloak, and describes how some enterprising scientists are working towards making things invisible using nanotechnology and mirages.

SciShow explains why stars do that twinkling that all the kids are singing about, and explains how astronomers can get around it to make observations, and why it can be kinda useful.

SciShow explains how three important ingredients -- sunlight, water, and you -- interact to create the illusion of a rainbow. The colorful details are inside!
