Kevin Smith’s telescope is protected by his large dome,
which opens to let his telescope point at the night Sky
for either observing or astrophotography.
Astronomy
- study of the night sky is called astronomy.
- astronomy – from Moon, moons, asteroids, comets, planets to stars, nebulas, galaxies.
- astronomy – most ancient of all the sciences, back dated at least over 4,000+ years.
- ancient Egyptians used their knowledge of astronomy; working out their calendar and align the pyramids.
- astronomy – ‘astro’ means ‘star’ and ‘nomy’ meaning ‘law’ – this word comes from the ancient Greek.
- use telescope to observe objects that are too faint or too small to be seen with naked-eye.
Professional Astronomers
- usually study photographs and computer displays instead of staring through telescopes.
- many space objects only show appearing on long-exposure photographs.
- can be spotted for new objects in the night sky by laying some current photographs over some previous photograph that they are looking for difference to spot – see below.

Space objects
- space objects give out other kinds or radiation besides light
- astronomers have special equipment to detect this. (See radio and space telescopes.)
