Antony Hewish is a very smart man who did something very important for science a long time ago. He worked with a team to build a special machine called a radio telescope. It was like a big dish that could catch different kinds of waves that come from space.
Antony and his team used the radio telescope to study the waves that come from a star called a pulsar. Pulsars are like lighthouses in space that send out waves in a very special pattern. Antony discovered this pattern by studying the waves that his machine caught.
Antony and his team were very excited about this discovery because it helped them learn more about how things work in space. They even won a big prize called the Nobel Prize for their work! Now, lots of other scientists use the things that Antony discovered to learn even more about space.
