Ian Morison
Gresham Professor of Astronomy Ian Morison made his first telescope at the age of 12 with lenses given to him by his optician. Having studied Physics, Maths and Astronomy at Oxford, he became a radio astronomer at the Jodrell Bank Observatory and teaches Astronomy and Cosmology at the University of Manchester.
Over 25 years he has also taught Observational Astronomy to many hundreds of adult students in the North West of England. An active amateur optical astronomer, he is a council member and past president of the Society for Popular Astronomy in the United Kingdom.
At Jodrell Bank he was a designer of the 217 KM MERLIN array and has coordinated the Project Phoenix SETI Observations using the Lovell Radio Telescope. He contributes astronomy articles and reviews for New Scientist and Astronomy Now, and produces a monthly sky guide on the Observatory's website.
Whole cosmic system of matter and energy of which Earth is a part. Its main constituents are the galaxies, within which are stars and stellar groupings and nebulae (seenebula). Earth's Sun is one star among the billions of stars in the Milky Way Galaxy. All atoms, subatomic particles, and everything they compose are also part of the universe. The universe is governed by four fundamental forces: the strong force, the weak force, the electromagnetic force, and gravitation. Numerous theories have been proposed for the origin and structure of the universe. See alsobig bang; cosmology; expanding universe; steady-state theory.
