Happy (late) Space Science Saturday! Did you know that NGC 936 is also known as the Darth Vader Galaxy because it looks like the Twin Ion Engine starfighters flown by the Darth Vader and his crew in the movie Star Wars. NGC in the name stands for the New General Catalogue of Nebulae and Clusters of Stars tars which was compiled by Danish astronomer Johan Ludwig Dreyer.

When the Full Moon occurs as the Moon is at its nearest point during its orbit of Earth, we call it a Super Full Moon, and the next one is tomorrow, November 5. Technically, a Supermoon is called a perigee-syzygy of the Earth-Moon-Sun. The term syzygy is used to describe when three celestial bodies align in a straight line.

Happy Space Science Saturday! Did you know that the Pleiades, seen in this image, is also known as the Seven Sisters or Messier 45? The cluster is estimated to be 150 million years old, with its brightest stars forming within the last 100 million years. The Pleiades are visible to the naked eye, as they are one of the clusters nearest to Earth., and can be seen from most parts of the world, except the Arctic Circle.

Happy Space Science Saturday! This Wednesday, October 29, Mercury will be at its greatest eastern elongation which is the best time to view the planet from Earth’s surface. During this period, Mercury will be at its highest point above the horizon in our evening sky and farthest away from the Sun. The best chance to view Mercury will be just after sunset.

Happy Space Science Saturday! We have stellar news for stargazers; the Orionids Meteor Shower peaks this week between October 20-21! Better yet, we will have a New Moon which means minimal moonlight and optimal meteor viewing conditions
