Under the link "What is radio astronomy?" you can read all about radio astronomy and learn about visible and invisible light, radio wavelengths and what radio astronomers actually "see".

But of course there is much more to know about astronomy in general. Below you can find some links to interesting websites that can help answer any questions you may have:

• The Portal to the Universe: features news about anything in astronomy, astronomy pictures of the day and live images of the Sun.

• World Wide Telescope: World Wide Telescope (WWT) enables your computer to function as a virtual telescope, bringing together imagery from the best ground and space-based telescopes in the world.

• Google Sky: To help you explore the far reaches of our universe, Google has teamed up with astronomers at some of the largest observatories in the world to bring you a new view of the sky and look at millions of stars and galaxies.
