Classifying Galaxies

Scientists classify everything from the smallest cells to the largest galaxies, but how do they decide on a classification system? Scholars use 40 pictures of galaxies taken by the Hubble Space Telescope to sort and try creating their...

Sometimes fuzzy, sometimes irregularly shaped—and occasionally cannibalistic? These are just a few of the remarkable galactic facts contained in a short video that's sure to amaze! The narrator describes the four main types of galaxies,...

Sal gives an example of where the Hubble telescope looks, as well as the level of detail that the camera can see. 

Prepare to be amazed! Look deep into the darkest part of the night sky, courtesy of a video from a vast physics playlist. Young astronomers see hundreds of galaxies through the eye of the Hubble Telescope. 

Could there really be over 200 billion galaxies? It turns out the number may be closer to two trillion galaxies! A video presentation discusses the existence of galaxies in the universe. The narrator explains how scientists make their...

Worlds within worlds! Journey to galaxies near and far with a thought-provoking video. Young astronomers learn how scientists detected very distant galaxies using their electromagnetic signatures far outside the visible range. Other...

The Milky Way belongs to a cluster of galaxies called the local group and it could be considered our neighborhood! Use the PowerPoint to present information on the different galaxy types, both local and farther away. Scholars learn how...

Hubble and his amazing telescope were key factors in determining what we know about galaxies. Introduce your learners to the types, composition, and incredible distance of galaxies. This is a simple and easily understood clip appropriate...

Add a little color to the universe. Learners recreate images of the galaxies using real data and Photoshop software. They display their images in a Hubble tuning fork diagram by classifying and categorizing their shapes.

Have your scientists ever asked what would happen if two galaxies collided? Use this clip to show what was seen through the Hubble telescope: the collision of two galaxies. You'll be able to narrate this clip any way you like, since it's...
