The pink splotch on the planet shows the X-rays detected in 2002 imposed on a photo of Uranus taken in 2004 at the same orientation.

Scientists Detect X-Rays Radiating From Uranus

The beams could be scattered light from the Sun, fluorescence from Uranus's rings, or produced by auroras on the ice giant

Previous research has shown that a gorilla's larger body size is linked to reproductive success and social rank. The chest-beating could be another way for the gorillas to convey their size to others and, in turn, avoid fights that could result in serious injury or death.

Gorillas Beat Their Chests to Communicate With Each Other

The larger male apes have lower frequencies in their pounds and may use chest-beating to signal their social status, strength, and size to others

During the dive mission, the divers found and captured footage of the ship's bridge, midsection, and bow that had hull number "557" still visible on both sides.
