Compact stars

Compact stars are extremely dense remnants of massive stars that have exhausted their nuclear fuel. When such a star can no longer maintain pressure to counteract gravity, it collapses into a very small, dense object. Types include white dwarfs, neutron stars, and black holes, each with distinct densities and sizes. Neutron stars are incredibly dense, with a teaspoon of material weighing about a billion tons. Black holes are so dense that not even light can escape their gravity. These objects showcase the extraordinary outcomes of stellar evolution and the balance between gravity and pressure.
