The search for alien life is one of humanity's biggest questions. While there are no little green men just yet, there's tantalizing evidence to consider.
We Found It: Traces of ancient rivers and polar ice caps suggest that Mars was once wetter, raising the possibility of past life.
Under the Ice: Jupiter's moon Europa likely has a vast saltwater ocean—could life exist in its depths?
Curiosity Rover Sniffs It: Methane on Mars can be biological in origin (but may have other sources too).
So Many Worlds: Discoveries of planets around other stars show us that planets are common – upping the odds for life.
Life Finds a Way: Organisms surviving in harsh conditions (hot springs, deep sea) prove life's resilience.
Building Blocks: Amino acids, the basis for proteins, exist in nebulae and even on comets.
