Our Alarmingly Close Shave with an Asteroid
How often do we miss asteroids like 2017 OO1, and what are astronomers doing to limit their impact? Meanwhile, distant icy worlds might not look as promising in our search for extraterrestrial life as scientists once thought.

Why Venus Is THE WORST
Venus was once thought to have been very earth-like and pleasant, but now it's considered a harsh wasteland that we wouldn't even send a robot to.

Meteors
Today Phil helps keep you from ticking off an astronomer in your life by making sure you know the difference between a meteor, meteorite, and meteoroid. When the Earth plows through the stream emitted by a comet we get a meteor shower....

Asteroids to Watch Out For
Hank tells us about NASA's Near-Earth Object Program, which tracks the paths of asteroids and categorizes them according to the likelihood that they will strike the Earth at some point in the future.

TED-Ed: Where did Earth's water come from? - Zachary Metz
Water covers over 70% of the Earth, cycling from the oceans and rivers to the clouds and back again. It even makes up about 60% of our bodies. But in the rest of the solar system, liquid water is almost impossible to find. So how did our...
