Create a Hubble Tuning Fork diagram

Galaxies are huge collections of stars, gas and dust held together by gravity. Our Galaxy, the Milky Way, is known as a spiral galaxy as it has spiral arms that wind their way around the center of the galaxy (or bulge). The first galaxies were identified as far back as the 17th Century by Charles Messier. Messier compiled a list of 110 star clusters and spiral nebulae which he discovered while searching the sky for comets. It wasn't until the early 20th century however that these nebulae were in fact spiral galaxies.

Making Craters

23 Oct 2008

In this activity we will be using a specially written web application called the Impact Calculator. This has been written by the Faulkes Telescope team. You will need to have Flash Player 9 (or higher) installed for it to run in your web browser (you will be directed to download the necessary plugin, if it is not installed).

Measure the diameter of the Sun

01 Mar 2012

The Sun moves across the sky at a constant rate because of the rotation of the Earth. By measuring how fast the Sun moves you can work out how big the Sun appears in the sky. All you need are some household items and about 20 minutes on a sunny day.

Observing Asteroids, NEOs and Comets

25 Jul 2008


Asteroids, also known as Minor Planets or Planetoids, are a class of astronomical object generally used to describe a diverse group of small bodies that drift around the Solar System in orbit around the Sun. A near-Earth object (NEO) is a Solar System object whose orbit brings it into close proximity with the Earth.

Play Bingo with Charles Messier

04 Jun 2009

Charles Messier lived in Paris in the 18th century. He wanted to become famous by discovering comets. When he looked through his telescope he often re-discovered objects which were already known and were not comets. So he didn't waste time, each time he found an object that did not move in the sky he catalogued it.

Solar System Taboo

17 Nov 2009

Cut out the name cards for objects in the Solar System and hand them out to the students.  Ask the students to try and describe the object given at the top of the card, but without using the 3 words underneath. (This game is based upon the popular board game, Taboo, and has been amended from the association for astronomy education website where more astronomy resources can be found - )

Star in a Box
