NASA predicts a rare "once-in-a-lifetime" summer nova explosion, a celestial event where a star undergoes a rebirth due to a white dwarf star accumulating matter from a neighboring star, triggering nuclear fusion and temporarily increasing brightness. This event offers skywatchers a unique opportunity to witness the rebirth of a star, with potential sightings during the summer months. The exact timing of this event is not yet known.
