| Optical telescopes | telescopes we use to enhance the visible object. Refracting and Reflecting |
| Refracting Telescope | One type of Optical Telescope which uses lenses |
| Reflecting Telescope | One type of Optical Telescope which uses mirrors |
| Hans Lippershey | Invented the Refracting telescope in 1608 |
| James Gregory | Given credit for the earliest design of the reflecting Telescope 1663 |
| Sir Isaac Newton | Given credit for making the first reflecting telescope 1672-1688 |
| Convex | Bean shaped lens. Wider in the middle than at the top |
| Concave | Caved in shaped lens or mirror |
| Electromagnetic spectrum | Range of visible and invisible light from a star or nebulae |
| Spectrum | range of colors in visible light-ROYGBIV |
| Galileo | Astromer, mathematician. Discovered 4 moons orbitiing Jupiter using a refracting telescope in 1610. Showed that not everything orbits earth. |
| Radio Telescope | A dish shaped telecope that detects the radio wave spectrum to produce images of objects emitting these waves. |
| Galilean Moons | Europa, Callisto, Ganymede, and IO |
| Ganymede | Largest Moon in the solar system - diameter of 5262 km.3,280 miles |
| ROYGBIV | Colors of the spectrum in order. |
| Electromagnetic Radiation | All the energy and particles that are emitted from the sun or stars. |
| Yerkes | Largest (40") refracting Telescope in the world |
| Keck Telescopes | Largest (400"/10m mirror) reflecting telescope. 3rd largest |
| Arecibo | World's Largest single Radio Telescope iin the world |
| Y-VLA | 27 Radio Tescopes in a Very Large Array (VLA) acting as one Radio Telescope |
| Hubble Telescope | Orbiting Reflecting Telescope, spectroscope @593 km or 370 mi above earth. |
| Edwin P. Hubble | Astronomer who discovered that the Universe is expanding in the 30's. Was honored by having a Telescope named after him. |
| Nebula | Giant cloud of gas (Mostly H) and dust where stars are born and die. Sometimes refered to as "stellar nurseries" |
| Supernova | Exploding star. Creates the heavier elements. Giant and supergiant stars die this way. |
| Nova | Explaning dying star that eventually collapses in on itself creating a white dwarf. Average size stars die this way. |
| Comet | Snowball in space |
| Moon | object that orbits a planet |
| Planet | Spherical object that orbits the sun |
| Mercury | smallest panet and closest to the sun |
| Venus | Earths twin, 2nd from the sun |
| Earth | Our planet. Third from the sun |
| Mars | Red planet 4th from the sun |
| Asteroid Belt | Area where most asteroids exist between Mars and Jupiter. |
| Jupiter | Largest Planet. Has 64 moons. Ganymede is its largest. |
| Saturn | 6th planet from the sun. Known for its rings. 2nd largest |
| Uranus | 7th planet |
| Neptune | 8th planet |
| meteor | asteroid like object in our atmosphere |
| Meteorite | asteroid like object hit earth |
| Meteoroid | asteroid like object outside of our atmosphere |
| Sun | Our star, center of the solar system |
| dwarf planets | Eris, Ceres, and Pluto |
| Newton | Invented the reflecting telescope between 1668-1672 |
| LBT | Large Binocular Telescope 11.8m aperture mirror. As of _2011 this is the World's largest |
| GTC | Gran Telescopio Canaries 10.4m mirror. #2 largest |
