Geoscience

Would it be the end of humanity?

Fall foliage from hundreds of miles up

The Nullarbor terrain isn’t that different than the red planet

The secret may lie in the mitochondria

There are a lot of variables

And it helped kick‑start life on Earth

Two snow dumps in just a few days

Long after the lava stopped flowing, enormous eruptions altered Earth’s climate and societies all over the globe

And there are more than 50,000 others like it worldwide

The speed of the soothing sounds could spell disaster

What on Earth for?

It’s what’s on the inside that counts
