FREQUENCY : The rate or number of crests of a wave that move past a given point in a given unit of time.
UNIVERSE : All of time and space and its contents. Includes, planets, moons, stars, galaxies, and asteroids.
BLACK HOLE : A celestial object that has a gravitational field so strong that not even light can escape it, created by a supernova.
ELLIPTICAL : A galaxy having an elliptical shape, three-dimensional with random orbits around its center.
STAR : A sphere made up of extremely hot gases. Our Sun is a Medium size.
GAMMA RAYS : Very short wavelength and very high energy.
MICROWAVES : Wave with a wavelength shorter than a radio wave but shorter than an infrared wave. Used in radars and communications.
WAVELENGTH : The distance between successive crests of a wave.
MAIN SEQUENCE : A series of star types n a band from the upper left (hot bright stars) to the lower right (cool dim stars).
HR DIAGRAM : A graph that plots stars organized by luminosity and their temperature.
SPIRAL : A galaxy with spiral shape that contains a central bulge thought to contain a black hole.
NEBULA : A cloud of gas and dust in outlet space.
ULTRAVIOLET : Light has shorter wave lengths than visible light.
INFRARED : A wave of light invisible to the human eye longer than an ultraviolet ray and shorter than a microwave .
SUPERNOVA : The explosion of a star, possibly caused by a gravitational collapse, which increases the star's luminosity.
GALAXY : A gravitational bound system of stars, separated from similar systems by vast region of empty space.
X RAYS : An electromagnetic wave of high energy an very short wavelength. Able to pass through many material.
LIGHT YEARS : A unit of length in astronomy equal to the distance that light travels in one year in a vacuum.
