A type-I supernova occurs when a white dwarf star accumulates mass from a companion star until it reaches a critical threshold, triggering a runaway nuclear fusion reaction. This causes the white dwarf to explode in a bright supernova event.

Why can't stars fuse iron, leading to their eventual collapse and supernova explosion?

Stars cannot fuse iron because it requires more energy than it produces, causing the star to lose its balance between gravity and radiation pressure. This imbalance leads to the star's collapse and eventual supernova explosion.
