What is a Neutron Star?

The video tutorial explains the life cycle of stars, focusing on the outcomes of supernova explosions. Stars with different masses leave behind either neutron stars or black holes. Neutron stars, unlike black holes, are observable and are known for their extreme density and gravitational effects. The video discusses the challenges of studying neutron stars due to their extreme conditions and highlights NASA's NICER mission, which aims to explore these celestial bodies further. The mission also includes a technology demonstration called sextant, which uses neutron stars for navigation in deep space.
