Organic bubbles that could serve as dwellings for primitive life have been discovered inside a space rock that fell to Earth nearly three years ago. The frozen chunk of stone and metal was recovered in the Yukon Territory after eyewitnesses saw it’s dramatic breakup in the sky. Inside the so-called Tagish Lake meteorite, frozen and well preserved, researchers have now found what they call organic hydrocarbon globules. Similar bubble-like structures have previously been created in laboratories at NASA’s Ames Research Center, under conditions designed to simulate how Nature might have cooked up the first life on Earth.
