  • The discovery of planets orbiting around other stars has been one of humankinds greatest achievements. The existance of these 'exo-planets' can challenge our perception of our place in the universe. Since the first confirmed detection of a planet around another normal star (51 Peg) in 1995, many thousands of planets have been discovered. Indeed, it is likely that most stars will have their own system of planets. It is important in answering the question - is there intelligent life out there?

  • October is here! It is one of our favourite months as there is so much more to see in the sky and the nights are getting deliciously darker. One thing to remember when you are stargazing is to wrap up warm when you venture outside. The nights are getting much colder, and with some of the best stargazing occurring in the early hours of the morning, we don’t want anyone catching a chill. Thermals and a thermos filled with hot chocolate or coffee will do the trick. Also don't forget that we will be starting our Star Tracker evenings in the coming months!

  • Astronomers now know many hundreds of planets orbiting other stars in our Galaxy. These show an incredible amount of diversity in their basic properties such as size and temperature with no two planets being quite the same. But the Earth is still unique among planets within or outside our solar system in its ability to support life
