"When you think of outer space, you’re likely picturing stars, planets and
moons. But much of space is filled with clouds of gas, plasma and stardust –
known as interstellar clouds.
In the local parts of our galaxy alone there’s a complex of roughly 15
individual interstellar clouds. The Solar System is currently traversing one of
them, aptly named the Local Interstellar Cloud. The origin and history of these
clouds are believed to be tightly connected to the birth and death of stars.
But we can see their imprints right here on Earth, in a place you might not
expect – Antarctic ice.
My colleagues and I have been studying stardust trapped in old Antarctic snow
and ice to trace the history of our solar neighbourhood, including the Solar
System itself.
In a new study published in
Physical Review Letters, we found a subtle clue
that reveals our Solar System’s movement through the local interstellar
environment over the past 80,000 years."
