30 years ago, an amateur astronomer noticed a white dwarf star suddenly getting brighter. New research shows this is due to a Very Late Thermal Pulse, a type of helium flash. The star has heated up and become brighter, and is now called a 'born again' star. It's evolved into a Wolf-Rayet type star, and astronomers will get to watch as it continues to evolve on human timescales.
