A photoreal view of Saturn's moon Iapetus showing its stark two-tone surface and the immense ridge running along the equator

Iapetus Has an 800-Mile Wall Around Its Equator

Saturn's moon Iapetus has an 800-mile wall running almost perfectly along its equator, rising as high as 13 miles in places. Cassini exposed one of the strangest off-world anomalies in...

Victorian-era brass telescope on a tripod at the bank of a perfectly straight fenland drainage canal stretching to the horizon under overcast English skies

The 6-Mile Canal That Proved Earth Never Curved

In 1838, a self-taught English surveyor aimed a telescope down a six-mile drainage canal and claimed the water was perfectly flat. Official science dismissed him. Then they repeated the experiment....

Ancient underground tunnel carved into volcanic rock in Cappadocia

The Underground Network

Derinkuyu is not a one-off. Over 200 underground cities connected by tunnels stretch across Cappadocia — and we are still finding new ones.
