The Planets with Inside-Out Weather
Way out in the solar system, the heat of the Sun drops off dramatically, so the gas giants get just a tiny percent of the solar radiation that reaches Earth. Instead, their weather is fueled from the inside out!
Crash Course
Asteroids
Now that we’ve finished our tour of the planets, we’re headed back to the asteroid belt. Asteroids are chunks of rock, metal, or both that were once part of smallish planets but were destroyed after collisions. Most orbit the Sun between...

How Big Are the Mountains on a Neutron Star?
The extreme mass of neutron stars leads to enormous gravitational pulls, resulting in nearly perfect spheres. But those imperfections, or mountains, might be able to help us spot more neutron stars in the future! And back on Venus, more...

Is an Ice Age Coming?
We're living in a brief window of time where our planet isn't frozen underneath a giant layer of glaciers. How much longer will the moderate climate that we've come to know as "normal" continue? This episode looks at how the changes in...

The Gamma Ray Burst of 775
About 1200 years ago, Earth may have experienced one of the rarest and most powerful cosmic events a planet can be exposed to: a gamma-ray burst. If it did, well, let's just say that we, as living things on Earth, are lucky it wasn't worse.

Gravitational Force
In this video Paul Andersen explains how an object with mass placed in a gravitational field experiences a gravitational force. On the Earth this gravitational force is known as weight. The gravitational force is equal to the product of...
