Why Do Neutron Stars Spin So Fast?

💡 The Answer

• When a massive star collapses, its core shrinks dramatically, conserving angular momentum and causing extremely rapid rotation.
• Some neutron stars spin hundreds of times per second, faster than a kitchen blender's blades on high speed.
• This spin is detected as regular pulses of radiation, earning them the name pulsars.
• The combination of tiny size and huge mass makes their rotational speed one of the highest known in the universe.
