What key material composition distinguishes Supernova Remnants in interstellar space?
Answer
Heavier elements forged during the star's life and the explosion
Supernova Remnants are the expanding gaseous clouds resulting from the catastrophic explosion of a massive star. Crucially, these remnants are enriched with heavy elements. These heavier elements were either synthesized within the star over its lifetime or created instantaneously during the high-energy environment of the supernova explosion itself. This process is vital to galactic evolution, as these newly forged elements are then distributed throughout the interstellar medium to become raw material for future generations of stars and planets.
