This Hubble Space Telescope image of a spiral galaxy viewed 'edge-on' reveals an intriguing warped disk that illustrates how a galaxy's shape can be deformed by gravity. Here, the fragile disk looks like pizza dough that has been tossed into the air
Text describes the galaxy's most prominent features in detail and compares the image with a 'face-on' portrait of another spiral galaxy.
Included is an inquiry-based classroom activity that focuses on the image and text.
This Hubble Space Telescope image shows an unusual edge-on galaxy, revealing remarkable details of its warped, dusty disk and showing how colliding galaxies spawn the formation of new generations of stars. Includes a classroom activity.
Teachers can use this lithograph as:
