1. Constellation ^[NEW]

A constellation is an area on the celestial sphere in which a group of stars forms an imaginary outline or pattern, typically representing an animal, mythological person or creature, or an inanimate object. The origins of the earliest constellations likely go back to prehistory.

2.Soil Samples ^[NEW]

Investigators also compared those microbes with those living in 52 other soil samples taken from all around the planet. The park had organisms that also exist in deserts, frozen tundra, forests, rainforests, and prairies. Antarctica was the only area that had microbes that did not overlap with those found in Central Park. Only a small percentage of the park’s microbes were found to be already listed in databases.

3.Brain (Version 2) ^[NEW]

The brain is divided into its ‘hemispheres’ by a prominent groove. At the base of this lies nerve fibers which enable these two halves of the brain to communicate with each other. But the left hemisphere usually controls movement and sensation in the right side of the body, while the right hemisphere similarly controls the left side.
