Pulsar

Real World Example

Imagine you're trying to find a friend in a crowded room by looking for their flashlight beam that briefly sweeps across the room. This is similar to a pulsar, where a rapidly spinning neutron star emits beams of radio waves that sweep across the sky like a lighthouse. Just as you can only spot your friend's flashlight when it points in your direction, we can only detect a pulsar when its beam is pointed toward Earth, creating a regular pulsing signal.
