From Gravitational Waves to James Webb Telescope: How to reach the general public about Physics and Astronomy

In 2015, when the gravitational waves were first detected, it raised a lot of public interests. In July 2022, when James Webb Telescope sent back its first pictures, the interests in Physics and Astronomy once again were raised in general public. NASA funded a few public libraries around the nation to host a series of events called "NASA @My Library".

Through the various experiences from talking to the Boy's Scout on their "Astronomy Day" to giving a lecture in the "NASA@My Library" program, I have learned a lot about communicating science with the general public. In this article, I would discuss how to talk to an audience with a large range of age groups, how to use the big astronomical events that were lucky enough to make onto the News to generate pulic interests, how to maintein the interests between such events, how to promote astronomical programs and how to support the public libraries in science events.
