Scientific Thinking

Galaxies do not exist alone – they are part of groups. These groups can also be part of larger clusters with hundreds of thousands of galaxies. Each galaxy type has smaller versions called dwarf galaxies. Our own galaxy, the Milky Way, belongs to a group called the Local Group. 

Galaxies are vast collections containing billions of stars, planets, and massive clouds of gas, dust, and ice. Understanding galaxies is a key part of astronomy. One important tool for studying them is classification—grouping them into a few different categories. 

Should humans colonise Mars? Is there life in the Universe? Science continually seeks to answer big questions - but it takes a lot of research and communication to come to a consensus. 

Why not host a debate and try it yourself?
