Twitter is a great place for astronomy and space fans to learn more about spaceflight, the cosmos and the people who are expanding our knowledge of the Universe.
Social media as a concept may be scoffed at by many, but one of the things it has done is opened up a wealth of knowledge and expertise that otherwise would be inaccessible for many of us.
In what other era might you have been able to ask your favourite astrophysicist a question about the nature of the Universe, or found out in real time what astronauts are eating on the International Space Station?
And if you’re the only one in your circle of family and friends with an interest in space and astronomy, you can find like-minded people who share your passion simply by clicking on a hashtag or finding the right groups to follow.
Astronomy being a primarily visual medium, social media is also a great place to access and share astrophotos, see the latest images of the Solar System or Universe beamed back by space probes and rovers, discover archive footage from the history of crewed spaceflight or get tips on astrophotography from world-renowned experts.
If you’re a space and astronomy geek, Twitter is a fountain for knowledge about the Universe. We’ve picked out some of the best Twitter accounts to follow for all things cosmic.
