"Using machine learning techniques and data from the All-Sky 
Automated Survey for Supernovae
(ASAS-SN) and several other surveys, astronomers have identified
378,861 variable stars, of which 262,834 are known variables and 116,027
are new discoveries.

“Variable stars are sort of like a stellar laboratory. They’re really
neat places in the Universe where we can study and learn more about how
stars actually work and the little intricacies that they all have.” SciNews
