NASA: 'Once-in-a-lifetime' nova eruption could happen any day

A NASA illustration shows how the nova eruption of distant T CrB might look. The U.S. space agency says the nova should be visible to the naked eye and occur anytime from now until September. A guide provided by NASA shows how to locate T Coronae Borealis — known as T CrB. NASA advises to first look for the constellation Hercules, then scan between Vega and Arcturus to find T CrB.

A nova eruption predicted to occur by September is being described by NASA as a “once-in-a-lifetime” event that will be visible to the human eye.
