One In Five Sun-Like Stars May Have an Earth-Like Planet

The Bad Astronomer writes "A new study, looking at over 40,000 stars viewed by the Kepler spacecraft, indicates that 22% of stars like the Sun should have Earth-like planets orbiting them — planets that are similar in size to our home world and with a surface temperature hospitable for liquid water. There are some caveats (they don't include atmospheric issues like the greenhouse effect, which may reduce the overall number, or at cooler stars where there may be many more such planets) but their numbers indicate there could be several billion planets similar to Earth in the Milky Way alone."

    and these aliens had thunderbolt hammer that were really nuclear weapons, and they flew around in vimanas which were really flying ships from a floating castle mothership, in order to interbreed with earth's primitive dwellers by taking human form.

    I love Ancient Aliens. one of the best shows on TV. Watching them come up with their wild pseudoscience theories is like watching a monkey discover how a cigarette lighter works.
