Something Tiny Tells a Big Story
Pale Blue Dot is the name given to a photograph of planet Earth taken on 14 February 1990 by Voyager 1, a robotic explorer built by NASA’s Jet Propulsion Laboratory. In the photograph, taken from a record distance of about 6 billion kilometres, Earth's apparent size is less than a pixel. The planet appears as a tiny dot against the vastness of space, among bands of sunlight reflected by the camera. The phrase "Pale Blue Dot" has come to represent a contemplative perspective on humanity's relationship to the cosmos.

Have you ever wondered how a dome-shelled tortoise turns itself back the right way up when placed upside down (a survival reflex known as “self-righting”)? It’s because its shell resembles a Gömböc (pronounced goemboets), the first-known three-dimensional homogenous object that has just one stable point and one unstable point of equilibrium when placed on a flat surface.

Sea-Monkeys have been a popular stocking stuffer for children since their “discovery” in 1957. So, what are they exactly? Despite their name, they're not monkeys. And they don't live in the sea.
