[00:00:00]Space isn't empty.

[00:00:01]>> [music] >> It's filled with invisible radiation.

[00:00:04]The biggest source is the sun.

[00:00:06]The sun constantly blasts charged particles across space in something called the [music] solar wind.

[00:00:12]But that's not even the worst part. Some radiation comes from exploding stars and violent events across the galaxy.

[00:00:20]These particles can travel near the speed of light and pass straight through spacecraft walls.

[00:00:27]That's one of the biggest dangers for future Mars astronauts.

[00:00:31]Earth's atmosphere protects us from most of it. Deep space doesn't.
