Free Variable Star Shorts
Many of the stars we see get brighter and even fainter over various periods of time. Some stars dim, brighten, dim again, and so on…in less than a second! Other stars can take years to change brightness—and not because the star is dying. These stars are called variable stars.
Explore a different variable star each month in 360 degrees on YouTube, or watch them in a planetarium dome, with these shorts from Ball State University, the American Association of Variable Star Observers, and the International Planetarium Society.

- PLEIONE IN TAURUS
