When I was five years old, my family moved into a 1930s semi-detached house with a long strip of garden. At the end of the garden was a miniature orchard of eight apple trees the previous owners had ...

The Indian Ocean "gravity hole" is a region where Earth's mass is reduced, leading to weak gravitational pull, lower-than-average sea levels and a puzzle scientists have only just begun to solve.

Why it's incredible: Evidence suggests it could be the greatest known impact crater on Earth. The Wilkes Land crater is a hole in the bedrock beneath East Antarctica's ice sheet measuring 315 miles ...
