Here’s a Kinda Sorta Map of All the Nearby Earthlike Planets

Here’s a cool graphic from New Scientist with their best estimate of how many habitable planets there might be in the galaxy. They started with the 3,588 planets discovered by the Kepler space telescope and then pared this back to only smallish planets in the “habitable zone”—not too near their star to boil over and not too far away to be iceballs. That got them down to 51 planets. But that only counts the planets we could see because our view from Earth was directly on their ecliptic. Extrapolating to all the rest produces 22,500 Earthlike planets. And since Kepler only covered 0.28 percent of the sky and only looked out 3,000 light years, extrapolating yet again produces a final estimate of 15-30 billion possibly Earthlike planets.

That’s too many to show, so the picture below is a guesstimate of all the Earthlike planets “visible with a good pair of binoculars on a dark night.” The grid in the lower right is the area of the sky mapped by the Kepler telescope. The rest is extrapolation. It probably doesn’t mean much, but it’s kind of a pretty picture.

But if there are really that many planets, where are all the people?

FOLLOW THE MONEY

Corporations and billionaires don’t fund journalism like ours that exists to shake things up. Instead, support from readers allows Mother Jones to call it like it is without fear, favor, or false equivalence.

And right now, a longtime friend of Mother Jones has pledged an incredibly generous gift to inspire—and double—giving from online readers. That's huge! Because you can see that our fall fundraising drive is well behind the $325,000 we need to raise. So if you agree that in-depth, fiercely independent journalism matters right now, please support our work and help us raise the money it takes to keep Mother Jones charging hard. Your gift, and all online donations up to $94,000 total, will be matched and go twice as far—but only until the November 9 deadline.
