The comet, known as C/2022 E3 (ZTF), will come within 26.4 million miles (42.8 million kilometers) of our planet, its closest approach in about 50,000 years.

The record-breaking tomb had a sealed sarcophagus containing the mummy of a man that a hieroglyphic inscription identifies as Hekashepes.

These patterns overlap in the location of the tissue loss but not in the severity; in other words, Alzheimer's patients exhibit a far greater degree of brain atrophy than cognitively healthy, obese adults of the same age do.

But this jaw-dropping spectacle was not caused by auroras. Instead, the iridescent rainbows were caused by clouds of tiny ice crystals floating higher in the atmosphere than is normally possible.

The tiny sun — consisting of a superheated plasma inside a 1-inch-wide (3-centimeter) glass sphere — produced sound waves that constrained the swirling plasma much like gravity does the actual sun.

The newfound fish weirdos, which researchers discovered hiding in a pitch-black pool the size of a kitchen table, have no scales or color, tiny rudimentary eyes that likely cannot see anything and an unusually large horn jutting out of their foreheads, a new study reveals.
