At Least 100 Million Planets In Milky Way
We’re not so alone. We’re not so special, either.
That specific figure of 100 billion planets has been suggested by earlier, separate studies, but the new analysis corroborates the earlier numbers and may even add to them, as it was conducted on a single star system — Kepler 32 — which contains five planets and is located some 1,000 light years away from Earth in between the patch of sky found between the constellations Cygnus and Lyra, where NASA’s planet-hunting Kepler Space Telescope is pointed…
overall, the chances of life on such planets are good, because they and their parent stars are likely to be much older and longer-lasting than Earth’s Sun, between two and 10 billion years. That’s because they sip less fuel over time.
So in the future, when Earth’s Sun begins to run out of fuel after another 4 billion years, any intelligent life still on the planet would do well to migrate to a system like Kepler 32.
Good to know we’ll have a place to go.Click here for reuse options!
