| A | B |
|---|
| Refracting Telescope | 2 convex glass lens, used by Galilieo, images not always clear |
| Reflecting Telescope | Use curved mirrors, clearer images, Newton |
| Radiation | Energy that is emitted in the form of heat or light mostly from nuclear reactions, which in large amounts is very harmful to living things |
| Hubble Space Telescope | Low distortion from Earth's atmosphere allows it to take extremely sharp images |
| Astronomical Units(AU) | Unit of length equal to approximately 93 million miles, Distance from earth to the sun |
| Nuclear fusion | The process by which multiple like-charged atomic nuclei join together to form a heavier nucleus, therefore |
| Solar nebula | The rotating flattened cloud of gas and dust from which the sun and the rest of the bodies in the solar system |
| Protostar | The beginning of a star formed by the contraction |
| Supernova | A stellar explosion, Expels more energy than the sun emits during it’s entire life, The death of a star, Black hole or neutron star |
| Neutron Star | Created after a supernova, hardened outter crust |
| White Dwarf | Highly dense Has no more energy Very hot at first, then cools becoming a black dwarf |
| Heliocentric | A sun centered Universe |
| Asteroid | Spherical, Orbits the Sun, Main asteroid belt between the orbits of Mars and Jupiter |
| Pulsar | A young neutron star that produces radiation and radio waves, and pulsates |
| Comet | Composed of rock, dust, water ice, and frozen gases Has a tail |
| Doppler Effect | Change in frequency of waves depending on movement of an object in relation to another. |
| Electromagnetism | The relationship between electrons |
| Black Hole | A region where gravity is so intense light can not escape it, Highly dense |
| Sirius | Brightest star in the known universe |
| George Lematre | Believed that the Universe was expanding, from a singularity he refered to as a primevil atom |
| Galilieo | First to look at night sky through telescope, found that vensus had phases, therefore further proving that the sun was the center of the universe. And that two objects will accelerate at the same rate. |
| Hubble | The milky way was just one of billions of gallaxies that are all moving away from eachother |
| Sun | made out of Helium and Hydrogen |
| Kepler | Reponsable for the expaining the eliptical orbits of the solar system |
| Life cycle of a Main Sequence Star | Stellar nebula, Average Star, Red Giant, Plantary Nebula, White Dwarf, Black Dwarf |
| Life cycle of a Massive Star | Stellar nebula, Massive Star, Red Supergiant, Supernova, either a neutron star or a black hole |
| Einstein | Proved that mass can distort space/time |
| Hottest Stars | Class O and Blue in Color |
| Coolest Stars | Class M and Red in Color |
| Mass | The energy and matter an object has |
