About 70,000 years ago Scholz's star passed through the Oort Cloud. It may have perturbed some comets from the Oort Cloud. But we won't know for a couple of million years because that's how long it would take for a comet to reach us.
The ANITA experiment, built to detect neutrinos, has detected very strange radio waves coming from deep below the Antarctic ice.
The Wallace Line divides species in Southeast Asia. A deep ocean trench prevents animal migration. Even flying birds rarely cross it.

Japanese researchers have made a compelling case that Earth’s oceans were once green, in a study published in Nature.
Now dubbed "New Kazakhstan," the deposit is said to have almost 1 million tonnes of cerium, lanthanum, neodymium and yttrium, elements used as components in devices such as smartphones, digital cameras and computer hard disks.
NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest Africa.
