"The Royal Museums in Greenwich wanted to extend the reach and reputation of the Royal Observatory and improve public understanding of astronomy with an innovative, engaging and effective marketing campaign. The only problem? It had a “miniscule budget” of just £550.

"That did not deter the in-house team, which set about working on a new project – Space LIVE. It aimed to broadcast major astronomical events such as the 2018 lunar eclipse and Ramadan new crescent moon sighting to audiences worldwide using Facebook live.

"Combining live-streams, astronomers’ commentary, user-generated content and SEO, as well as press channels to drive awareness, it delivered its goal. The campaign reached more than 310,000 people on Facebook and generated 193,000 views and 100,000 engagements, as well as driving 360,000 visits to the observatory’s website. It also achieved a number one search ranking on Google."
