100 Million Worlds May Have Complex Life, Say Scientists

I suppose it shouldn’t come as too much of a shock given how many stars are in our galaxy, and given the fact that most of those stars probably have planets. But a group of astronomers have published research that asserts the possibility of complex life on an incredible hundred million worlds in our galaxy alone.

It may seem like a lot, but it’s actually a pretty small number when you take into account the 17 billion earth-sized planets in our galaxy. At the very least, the conditions necessary to support life may exist on 100 million worlds, but maybe not necessarily complex life.

If this estimate applies to all galaxies, there could be as many as 500 billion planets harboring complex life. Wow!

Their research was published in Challenges of Astrobiology.
