How do Novae occur?
A nova occurs when a star of some sort collects hydrogen from a nearby companion (gas). This increases the mass of the star typically a white dwarf star and eventually results in a huge nuclear explosion due to fusion. This can happen with various star types, but it’s most common when there’s a compact and highly dense stellar remnant in close proximity to a star still has not gone supernova. A nova can have multiple explosions and it is usually extremely bright were you can see it with the naked eye.

  1. The Plural form of nova is novae
  2. Nova is a smaller version of a super nova. The explosion is about 1/10 Th
  3. Nova Centauri was an accidental discover. Scientist compared many pictures to discover it. They were looking at the right area at the right time.
  4. Supernovas are more common then a nova
  5. When a nova is super bright that usually indicates a shorter life span.
