One Of The Best Explanations For Why We Haven't Found Alien Life

So far, the only examples of sentient life we've found are right here on our own planet. It's not for lack of trying, though - we've sent out spacecraft deep into our solar system and, so far, still remain alone.
A forthcoming study in Journal of Cosmology and Astroparticle looks at the possibility that life as we know it may not require a star similar to our sun but could emerge on planets orbiting much smaller, weaker stars. If we do allow for the possibility of life around non-sunlike stars, then it turns out that the universe is likely to be much more habitable in the distant future than it is today.
