Astronomy Observation Lab
"Hi, everyone," Ellie said as people arrived in the astronomy class room. "There might be some thunderstorms tonight, but hopefully we'll get some clear skies to get a good look at some beautiful sights in the night sky.
"First we'll take a look at the Pleiades. The Pleiades (also known as M45 or the Seven Sisters) is an open cluster in the constellation of Taurus. It is among the nearest to the Earth of all open clusters, probably the best known and certainly the most striking to the naked eye. The cluster is about 12 light years in diameter and contains approximately 500 stars in total. It is dominated by young, hot blue stars, which have formed within the last 100 million years, up to 14 of which can be seen with the naked eye depending on local observing conditions. The arrangement of the brightest stars is somewhat similar to Ursa Major and Ursa Minor. It's a mini Big Dipper!
"We'll also take a look at the Ring Nebula, which is located in the contellation Lyra. It is among the most well known and recognizable examples of a planetary nebula, which is what we call the shell of gas left by a star at the end of its life. The nebula is located 2300 light-years from Earth and is illuminated by a central white dwarf.
Any special requests for things to look at?"
