Earth As an Extrasolar Planet

Posted by timothy on from the how-else-to-test dept.

sciencehabit writes "Astronomers have a theory that they can detect whether a planet light years away will be habitable by just looking at how its sun is reflected in its atmosphere. To test the idea, they pretended that they were observing Earth from a distant object — in this case, the moon. And sure enough, they picked up critical components for life in Earth's atmosphere: ozone, oxygen, sodium, and nitrogen."

    They could have just given me a few hundred thousand and I'd confirm for them that the Earth is hospitable for humans!
