About 40 percent of red dwarf stars may have Earth-sized planets orbiting them that have the right conditions for life.
Red dwarfs – which are smaller and cooler than our sun – are extremely common, making up 80 percent of stars in the galaxy. Their ubiquity suggests that there are tens of billions of possible places to look for life beyond Earth, with at least 100 such planets located nearby.
The new estimate comes from a team of astronomers using the European Southern Observatory’s HARPS planet-hunting telescope to look at a sample of 102 nearby red dwarfs over a six-year period. The telescope checked for a characteristic wobble from the star, indicating that at least one planet was tugging on it while orbiting around.
The search found nine planets with between one and 10 Earth masses, including two in the habitable zone, possibly giving them the right temperature to have liquid water. Because red dwarfs don’t produce as much heat as our sun, their habitable zones occur much closer to the star.
Tyler: First you have to give up. First, you have to know, not fear, know that someday you’re gonna die.

This will interest nobody but super Twitter nerds, but enough people ask me about it that I thought I’d do a wee post. Sometimes I repeat jokes on Twitter. This bothers some people. Granted, they are shit-breathed garbage people, as demonstrated by their taking the mental & caloric effort to write…
Favorite movie of all time.
