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

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


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?

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
