If We Ever Do Find Alien Life, Here's How It Might Happen
Searching for life beyond our planet is a slow, careful process.By Evan Thomas | August 30, 2016
We still can't say for certain whether extraterrestrial life is out there. But if there is, don't expect a big flashy announcement. Instead, it's something we'll get more confident about as time goes on.
We see signals in space that could be of alien origin all the time. Researchers in Russia detected one 15 months ago, but it hasn't been repeated since. No one else picked it up then, either. So the scientific community is skeptical.
But that's how scientists operate. If a signal ever was detected that really did come from aliens, we probably wouldn't know for sure at first. Instead, scientists would study it for years and years, ruling out the other possibilities.
