Regulus, a star in the constellation Leo, is known for its brightness and is one of the brightest stars in the night sky. It emits light continuously, but its light is not associated with a specific year since it has been shining for millions of years. The light we see from Regulus today actually left the star about 77 years ago, as it is located approximately 77 light-years away from Earth. Thus, the light we observe now originated from Regulus around 1946.
