Use Charles Messier's Catalog with your students to learn about the universe!
The Messier Catalog is a list of the best-known objects in the universe. Whenever you encounter a deep space object with an "M-number" such as M1, the Crab Nebula, you are being directed to the Messier Catalog. It contains star clusters such as M13, the Hercules Cluster, nebulas (nebulae) such as the Lagoon (M8) and Orion (M42), and galaxies such as Andromeda (M31), the Whirlpool (M51), and the Sombrero (M104).
The Catalog is often used by amateur astronomers, and it represents the first objects seen in newly-acquired telescopes. Professional astronomers also refer to the Messier Catalog names for deep space objects.
The teaching slides present the history of Messier and his Catalog, the types of objects that it contains, and their relation to the Milky Way Galaxy and the rest of the universe. It is designed as an introduction to the lab "Messier's Galaxies, Clusters, & Nebulae
" available on my TpT store for a modest charge. The slides can also be used as a general introduction to the contents of the universe, and they can help answer the question "What is out there?"
The teaching slides contain numerous deep space images from the Hubble Space Telescope and advanced amateur astronomers.
