DailyDirt: Aliens Aren't Coming To Visit Anytime Soon, But...
The search for aliens has been pretty fruitless so far, but that doesn't mean we should give up on it. Sure, there's little evidence that points to us ever finding aliens beyond our solar system -- and no way that we'll ever interact with distant aliens given the vastness of space and that darn speed of light limitation. However, if we can find some sign that we're not alone, that would be quite a remarkable discovery that could inspire us to greater goals, knowing that someone else is out there to impress or something? Or it would just be cool to be able to build a Dyson sphere of our own.

- KIC 8462852 is the name of a star system that has unusual features -- with explanations saying that it's a star surrounded by a strange field of debris, to more outlandish suggestions that an alien megastructure (perhaps a partial Dyson sphere) exists. A Dyson sphere (or a Dyson swarm) is a massive technological construction that would allow an extremely advanced civilization to harness an enormous amount of energy from a star. This is far from conclusive evidence for aliens, but it would certainly be a significant discovery if all the more mundane explanations don't pan out. [url]
- Instead of looking for messages from aliens, some folks are looking for evidence of ancient ruins in space. Interstellar archaeologists might find aliens on the Kardashev Scale with unnatural amounts of pollution or other anomalous space objects that might be detected. [url]
- Abiogenesis must have happened at least once here on Earth, right? If we could find some evidence that it's happened here more than once, though, that might improve the odds of life existing elsewhere in the universe. [url]
