The Star of David (in Hebrew Magen David, literally the “Shield of David”) competes with the menorah (seven-branched candelabra) as the most iconic and recognizable symbol in Judaism.

The star was almost universally adopted by Jews in the 19th-century as a striking and simple emblem of Judaism in imitation of the cross of Christianity. The yellow badge that Jews were forced to wear in Nazi-occupied Europe invested the Star of David with a symbolism indicating martyrdom and heroism.

The Jewish Encyclopedia cites a 12th-century Karaite document as the earliest Jewish literary source to mention a symbol called “Magen Dawid” (without specifying its shape). The name ‘Shield of David’ was used by at least the 11th century as a title of the God of Israel, independent of the use of the symbol.

Also known as primitive stars, these metal stars are common in farming settlements with German heritage and they’re believed to bring good luck. Like the superstition of hanging a horseshoe on a barn, the history of the barn star began as an attempt to ward off evil.

The Betsy Ross flag is an early design of the flag of the United States, named for early American upholsterer and flag maker Betsy Ross. Its distinguishing feature is thirteen 5-pointed stars arranged in a circle representing the 13 colonies that fought for their independence during the American Revolutionary War.

The gas is drawn into the center of the star due to gravity, and is supported by the internal pressure inside the star. Gravity acts equally in all directions, and the gas is dispersed symmetrically around the center forming a shape of a perfect sphere… or at least almost perfect.

Stars are star-shaped because of imperfection in our eyes Most stars are much like the Sun—giant balls of gas burning billions of miles away. These spherical stars pump out a steady stream of light that crosses vast stretches of space before it illuminates the night sky.
