Can A Nova Go Out And Come To Life Again?

Scientists recover nova first spotted 600 years ago by Korean astrologers. A new study pinpoints the location of a nova first spotted by Korean astrologers almost 600 years ago that now undergoes smaller-scale 'dwarf nova' eruptions. The work supports that idea that novae go through a very long-term life cycle after erupting, fading to obscurity for thousands of years, and then building back up to become full-fledged novae once more.

Again Life Come Out Nova Can

For a nova to be completely finished, all it's fuel has to be used up. While a typical nova event is enormous and emits massive amounts of energy, the core of the former star is not done. There are still many millions of metric tons of fuel at it's heart, fuel that will 'ignite' various reactions over the life cycle, until everything is inert. The remaining heart of a nova is usually some of the most heavy materials in the universe.
