The 'blaze star' T Coronae Borealis is set to flare into life any day now, going from invisible to as bright as the North Star overnight in a spectacular nova.
Once the nova appears it will be visible to the naked eye for a couple of days before disappearing for another 80 years.
Dr Rebekah Hounsell, a NASA expert on nova, says: 'There are a few recurrent novae with very short cycles, but typically, we don't often see a repeated outburst in a human lifetime, and rarely one so relatively close to our own system.'
Dr Hounel adds that this is 'a once-in-a-lifetime- event' to get front-row seats to a truly special cosmic event.
