The argument that life on Earth may have been seeded from the stars just received a major boost, as scientists have found the building blocks of life inside a meteorite that landed in British Columbia in 2000.
The Tagish Lake meteorite landed in January of that year, a streaking fireball that burst into more than 500 fragments which rained down on the lake. In its trip from the outer reaches of the asteroid belt it burned down from 56 tonnes to 1.3, and deep inside the fragments there are the basic building blocks of life, including the amino acids, sugars and hydrocarbons that could have jump started life on our planet.
This meteorite is the only uncontaminated example we’ve ever found, thanks to the quick actions of the people who spotted it. What the researchers have found is that the organic compounds in the rock date back to the early days of the solar system, or possible predate it.
