Today's Astronomy Picture of the Day shows variable star R Leporis, better known as Hind's Crimson Star, in the constellation of Lepus. Hind's Crimson Star is a variable star, a star that varies in brightness over a period of time.
There are many variables in the sky, far more than can be observed with professional instruments. For over one hundred years, amateur astronomers, many with very modes instruments, have contributed reams of data for use by professionals, through such organizations as the AAVSO. Take a look, it might be a place for you!
