What event results in the formation of a Supernova Remnant?
Answer
The catastrophic explosion of a massive star.
Supernova Remnants are the direct aftermath of one of the universe's most energetic events: the catastrophic explosion of a massive star, known as a supernova. This explosion generates an enormous, fast-moving shockwave that expands rapidly outward, violently sweeping up and heating the surrounding interstellar gas and plasma. These expanding clouds are crucial because they are responsible for distributing heavier elements synthesized during the star's life and the explosion itself, thereby enriching the interstellar medium for the formation of subsequent generations of stars and planets.
