Antarctica is fertile ground for meteorite hunters, because the space rocks that land there accumulate in glaciers and tend to become concentrated. One of these meteorites turned up something incredible, scientists reported in April.

In spite of its pollen and frozen forests,, exotic animals, Antarctica has also some species that go far beyond time, at least in the Darwinian way.

One of its grains, just 0,10 centimetres or 1/25,000 of an inch long, is a speck of dust from a star explosion called a Nova. The dust speck is older than the sun and according to evolution holds clues to the composition of the early solar system.
