What is this, or what are these? What was used to create these pictures?

Telescopes Collect light from far away objects and focuses it to form an image of the object Record by hand, with photography, and now digitally with charge-coupled devices Important Qualities Ability to gather Light Resolution = See Detail Magnification

Refractor Telescope or “spyglass” Galileo Used home-made telescopes to view the planets during the 1600’s

Solar Telescopes Multi Mirror Telescopes

Radio Telescopes

Space Telescopes Get above the distorting effects of Earth’s atmosphere View other wavelengths of light blocked by the atmosphere
