Compact objects

Compact objects are incredibly dense remnants of stars that have exhausted their nuclear fuel. They include white dwarfs, neutron stars, and black holes. White dwarfs are the cooled cores of small stars, packed into a volume similar to Earth’s. Neutron stars are the collapsed cores of massive stars, incredibly dense with a sugar-cube amount of material weighing billions of tons. Black holes are regions where gravity is so strong that nothing, not even light, can escape. These objects showcase extreme states of matter and gravity, providing insights into physics under conditions impossible to replicate on Earth.
