This oddball system of three stars might be our best chance at finding nearby life in the Universe.
Yes, NASA’s Perseverance rover found organics on Mars. So did Curiosity. Unfortunately, that doesn’t mean anything in the search for life.
50 years ago, Herman Chernoff proposed using human faces to represent multidimensional datasets. It was a good idea in theory — but a disaster in practice.
The cycles of life all rely on the dynamism of the Earth’s crust.
Instead of worshipping Yahweh, the devotees were perhaps dedicated to Mars and Jupiter.
There’s a whole lotta shakin’ goin’ on beneath the single plate of Mars.

From astrobiology to geology, a Moon base could serve as a laboratory unlike anything on Earth.
Slowing growth and limiting development isn’t living in harmony with nature—it is surrendering in a battle.
Out of the four rocky planets in our Solar System, only Earth presently has plate tectonics. But billions of years ago, Venus had them, too.
