A classroom activity in which students predict and then measure the rotational velocity of material in a nearby galaxy, using their knowledge of gravitation and Doppler shifts to deduce the presence of dark matter.

Have you ever looked up at the night sky and wondered about the stars? What makes them so special? Why are some even different colours? Join the Royal Observatory Greenwich astronomers as they explore the science behind the different types of stars in our Universe.

A classroom activity introducing the rotating Earth and the concept of longitude in which students carry out simple arithmetic to relates the 24 hour clock with the Earth’s rotation.

In this classroom activity, students use distance, speed and time to calculate how long a signal takes to reach us from Comet 67P.

The Rosetta Mission has captured the interest and imagination of a generation and it is not over yet! Take a look at our video which explains what Rosetta and Philae have achieved as well as the impact the mission has had on our knowledge of our very own solar system.

In this activity students use the famous Drake equation to estimate the number of planets that may harbour intelligent life in the Milky Way.

Students create their own timeline of the evolution of the Universe.

Students use special relativity to calculate the effects of a black hole on time. Accompanies the video 'What's inside a black hole?'.

Students look at the behaviour of gravity with distance to calculate the gravitational forces between people and celestial objects. Accompanies the video 'How will the Universe end?'.

In this classroom activity, students will use bearings to plot constellations. They are then asked to think about what they represent.
