Great outreach meeting today with Y5s at a local primary school. A brief recap of Life Cycle of Stars and then into ‘Black Holes’ Astronomy is a fantastic vehicle for developing science. 🔭🔭

A call to Labour to Rejoin the EU. "It’s nine years since the UK voted to quit the European Union. It has proven to be a disaster, and a disaster made greater by the election of Donald Trump. The world is at a pivotal moment. Stark political reality faces us."

Labour needs to stop being so afraid about rejoining the EU
Rejoining would revive our economy and boost our security
