QuestionAnswer
Eccentricity Deviation from a curve or an orbit.
Red Shift the change in the wavelength of light when something moves away
Blue Shift, an increase in frequency
Frequency, The number of wavelength that pass a certain point.
Wavelength, the distance from the peak of one light or sound wave to the peak of the next. Electromagnetic wavelengths vary from the short blips of cosmic rays to the long pulses of radio transmission
Absolute Brightness (magnitude), the brightness a star would have if it were at a standard distance from earth
Apparent Brightness (magnitude), how bright a star appears from earth
Stellar Spectra Continuous black body spectrum and photosphere
Universe, everything in space
Galaxy , A group of stars and planet and gases and other space stuff
Solar System, sun, planets, and all the other things that revolve around a sun
Star, A hot ball of gas
Planet, a celestial body moving in an elliptical orbit around a star.
Electromagnetic Spectrum, All of the frequencies or wavelengths of electromagnetic radiation
AU- Astronomical Unit, The distance from the Earth to the Sun
Solar Nebula, A large cloud of gas and dust such as the one that formed our solar system
Gas giant , Jupiter, Saturn, Uranus, Neptune
Nuclear fusion, Nuclei combine to form more massive elements
Convective zone, In the Convection Zone, very hot plasma rises and cools when its near the surface and then falls back down and up again and the cycle continue
Photosphere, The luminous envelope of a star the its light and heat radiate.
Chromosphere, a reddish gaseous layer which is above the photosphere of the sun or another star.
Corona , The rarefied gaseous envelope of the sun and other stars
Sunspot, a spot or patch appearing from time to time on the sun's surface, appearing dark by contrast with its surroundings.
Prominence, a gas projecting above the sun's chromosphere.
Solar Flare, a brief eruption of intense high-energy radiation that comes from the sun
Coronal mass ejection, A release of plasma
Light year, the distance that light travels in one year
Main Sequence, a diagonal area on an H-R diagram that includes more than 90 percent of all stars
HR Diagram, A graph relating the temperature and brightness of stars
Nebular, A large cloud of dust and gas in space
Red giant, A large, reddish star late in its life cycle
White dwarf, A small, hot, dim star that is the leftover center of an old star
Nova, a star that increases thousands of times in brightness and then fades
Neutron Star A star that has collapsed under its own gravity
Radiative Zone A layer in a star that energy is traveled toward the exterior of the star.
Pulsar, A rapidly spinning neutron star that produces radio waves
Black Hole A region of space having a gravitational field so intense that no matter or radiation can escape.
Formula For Eccentricity E=c/a
Cosmology Study of the universe
Kepler's Law 3 laws that are about planetary motion.
Elliptical Orbit When something revolves around another object.
