Stellar Remnants

Stellar remnants are the leftover cores of stars that have exhausted their fuel. When a star like our Sun runs out of energy, it sheds its outer layers and leaves behind a dense core known as a white dwarf. More massive stars can end their lives in supernova explosions, leaving behind either a neutron star—an incredibly dense object made mostly of neutrons—or a black hole, an area of space with gravity so strong that nothing can escape. These remnants provide valuable insights into the final stages of stellar evolution and the extreme conditions of matter.
