Uncover the Mystery of the Exploding Star – Crossword Solution Inside!

The answer to the crossword question “Exploding star is NOVA” is simply stating that a NOVA is a type of exploding star. A NOVA occurs when a white dwarf star in a binary system pulls matter from its companion star. The added mass triggers a nuclear reaction in the white dwarf, leading to a sudden release of energy and an explosion that causes the star to briefly brighten and become visible to us on Earth. However, unlike a supernova, a nova does not result in the complete destruction of the white dwarf and it can repeat its explosion in the future. Therefore, the crossword clue is indicating that NOVA is a specific term for an exploding star.
