How to Find ALIEN Dyson Spheres
On our search for alien lifeforms we scan for primitive biosignatures, and wait and hope for their errant signals to happen by the Earth. But that may not be the best way. Any energy-hungry civilization more advanced than our own may...

Cosmic Microwave Background Explained
HAS SPACE ALWAYS BEEN BLACK? As long as we've been around, YES. But the universe gets much more exciting, AND much BRIGHTER, as we start winding our clocks back to the early days of the universe. Near the beginning of the universe, when...

What Are We REALLY Using Space Lasers For?
Ever since we started launching stuff into space, we've communicated with spacecraft (and astronauts) using radio waves. But over the past few decades, scientists have experimented with a new technique that could make things a lot more...

Salmon Can Turn on Night Vision. Why Can’t We?
Most of us can only see certain wavelengths of light our entire lives. So why can salmon switch on night vision? We'll learn how they can reshape their eyes to see into the infrared.

The Sun Is Green
The Sun is green, actually. We'll go into why the blackbody effect means the Sun emits more green visible light than any other color, and why evolution and color perception mean it's ok to see it as yellow, anyway.

Some Of You Can See The Invisible
We know that not everyone's vision is perfect, which is why some of us need glasses. But some people can also just see more stuff than others! From seeing UV and infrared light, to even having bonus color receptors in our eyes, there are...

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!
