Understanding our Universe
The universe has always amazed people. Over time, our understanding of stars and galaxies has changed a lot.
- Stars
What we know about stars has changed over thousands of years. Early astronomers recorded the positions and numbers of stars. They did not think that stars could change. The first catalogue of stars was made by Chinese astronomers Gan De and Shi Shenfu around 400 BCE. Astronomers soon realised that 'new stars' could appear in the sky. We know these now as supernovae. The final explosion of a massive star's life.
