History and Mythology of Gemini Constellation In this blog post, we will explore the history, mythology, and significance of the Gemini constellation, as well as some of its most interesting features. With its distinctive shape and bright stars, Gemini has captured the imagination of stargazers for centuries. To learn more about February’s astronomy, visit our Eyes on the Skies post.The Gemini constellation, also known as the Twins, is one of the most recognizable and well-known constellations in the night sky. The brightest star in this very small constellation is Procyon, which means “before the dog” because it rises before the bright dog star – Sirius. Rounding out our three February constellations is Canis Minor, the Lesser Dog. Within Auriga, towards its left (east) side are three more open star clusters, each similar to the one found in Gemini. Many a time a camper who stays up past midnight in the summertime will note a bright twinkling object rising in the east. This star is one of the brightest stars in the winter sky, though it can also be seen rising around midnight during the summer. However, if you stretch your perspective a bit, you’ll see a house with a base, two walls ,and a three-pointed roof. Unlike its neighbour, seeing a charioteer here requires a tremendous amount of creative imagination. To the right of Gemini the Twins lies the constellation of Auriga, the Charioteer. While the cloud may have dissipated, the leftover stars can still be seen. Looking above its toe in binoculars, one can find an open cluster a loose grouping of stars that have all formed together from a giant gas cloud. The body of Castor extends downwards to its giant foot. Unfortunately, most of the six stars are too close together for us to observe without a special telescope. While most of these companion groupings occur as double stars (two stars in orbit around one another) Castor actually is made up of three pairs of double stars (six stars in total). Astronomers have found that nearly half of all stars have companions. Pollux’s brother star, Castor, is a remarkable star. Now, thanks to various methods including the orbiting Kepler spacecraft, we know of thousands of extrasolar planets. The star Pollux was one of the first discovered to be harbouring an extrasolar planet (2006) – a planet beyond our solar system. To remember which is which, remember that the star Castor is closer to Polaris, the North Star, than his brother Pollux. The constellation is a pair of stick figures “Castor” and “Pollux.” Each figure is named for the brightest star at its head. Unlike many constellations, Gemini really looks like what it is supposed to be – twin people. High overhead is the constellation of Gemini the Twins.

This month’s post will focus on three others, most notable Gemini the Twins. In last month’s blog, we discussed Orion the Hunter, as well as a number of other prominent constellations seen in the winter. Today, we recognize 88 official patterns or “constellations” of stars. To help memorize the different stars, patterns of connect-the-dot figures were created by many different cultures. The stars helped them try to understand their purpose, and the role they play in our lives. For thousands of years, humans have looked up at the stars.
