A mound of stars rises from the brim of a galactic disk in this image of an edge-on spiral galaxy.
This galaxy’s prominent features include a wide, flat disk, nearly 2,000 globular clusters and a bulge of stars similar to the Milky Way’s. Also, learn how the appearance of a galaxy differs depending upon the angle from which it is viewed.
Included is an inquiry-based classroom activity that focuses on the image and text.
This Hubble Space Telescope image shows the spiral Sombrero Galaxy. Viewed nearly edge-on, it reveals a dazzling bulge of central stars much like the ones in our own Milky Way. The text describes the galaxy's prominent features and discusses how galaxies' appearances differ depending on the angle from which they are seen. Includes a classroom activity.
