On-the-run government whistleblower Edward Snowden, who is living in exile in Russia, has aliens on his mind. In 2013, Snowden exposed the federal government's extensive, warrantless surveillance of everyday citizens.

These days, he has a lot to say about a lot of topics. That includes how encryption could be hiding aliens from us, despite our best efforts to find them.

Encryption is when one thing, like a series of numbers, is disguised to look like a totally different thing. Encryption is an incredibly useful tool, especially to protect your identity from hackers, cybercriminals and the government.

Snowden believes that aliens could be encrypting their signals, so it's possible space creatures are all around us and we'd never know it. He also believes that our increasing use of encryption could be hiding humans from aliens who want to communicate with us.

In case you're wondering, Snowden wasn't just killing time while in Russia. He was a guest on astrophysicist Neil deGrasse Tyson's podcast, "Star Talk."
