Analysis and Evaluation

The sea level rises and falls every day. These changes are called tides. Tides happen because of the gravitational pull of the Moon and the Sun on Earth's oceans. The Moon has the strongest effect because it is much closer to Earth. 

In 2017, the Liverpool Telescope was involved in the investigation of an exciting new discovery: the star system TRAPPIST-1.

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?

The Sun is a constant presence in our life on Earth. It gives us the heat and light we need to survive. But it is not a stable place. The Sun is a ball of hot plasma which is constantly changing.

You have probably seen the Moon in the sky, but have you ever studied it in detail?

You have likely heard about the Universe expanding. Or that redshift can tell us about the movements of galaxies. Both are difficult ideas to imagine and understand.

Every year, the Earth completes one orbit of the Sun and every year, you have a birthday!
