Supernova
A star that explodes and becomes extremely luminous in the process., a star that explodes and becomes extremely luminous in the process
Pegasus
Under the galaxy- The Great Square, (Horse) Major Stars: Algenib, Markab,Andromeda June-February
Cygnus
a constellation in the northern hemisphere between Pegasus and Draco in the Milky Way
Comet
A ball of frozen dust and rock that orbits the sun and has a tail that glows
meteor shower
An event where a large number of meteors enter the Earth's atmosphere from the same direction in space at nearly the same time. Most meteor showers take place when the Earth passes through the debris left behind by a comet.
aurora borealis
a colorful, glowing display in the sky caused when particles from the sun strike oxygen and nitrogen atoms in the ionosphere; also called the Northern Lights
black hole
An object so massive and dense that even light cannot escape its gravity.
super massive black hole
Is the largest type of black hole in a galaxy, on the order of hundreds of thousands to billions of solar masses.
Polaris
A creamy-white supergiant star that is a Cepeid variable in the Ursa Minor Constellation located in the Northern Hemisphere.
Sirius
Canis Major - the brightest star in the night sky
Mercury
Closest to the Sun; has a thin atmosphere w/ temp. extremes, an iron core, & many craters & high cliffs
Venus
2nd planet from Sun; has a dense atmosphere & known to rain acid w/ high temp.'s, a surface w/ craters, faultlike cracks, & volcanoes; sometimes called Earth's twin
Earth
3rd planet from sun; has an atmosphere that protects life & surface temp.'s that allow water to exist as a solid, liquid, & gas
Mars
4th planet from the sun, with two icy poles at the North and the South of the planet.
Jupiter
Appearance - The fast rotation causes the clouds to form bands around the planet
Uranus
7th planet from Sun; is large & gaseous, has a distinct bluish-green color, & rotates on an axis nearly parallel to the plane of its orbit
Neptune
8th from the sun, no atmosphere, furthest out, high methane content, has the great dark spot
Pluto
The 9th planet from the sun. In 2011 was converted to a dwarf planet.
sun
A typical star that is the source of light and heat for the planets in the solar system.
Stellar Black hole
Is a black hole formed by the gravitational collapse of a massive star (more massive than about 20 solar masses) at the end of its lifetime.
Galaxy
A collection of stars, dust, and gas bound together by gravity.
Saturn
The 6th planet from the sun, known for it's massive dust, ice, and dirt rings. Home to the moon, Titian which is the only moon with an atmosphere.
Red Stars
Stars with surface temperatures around 3300 Celsius, coldest type of star
White star
Second hottest star 10,000 degrees C
Blue stars
Young and hot stars, they tend to have shorter lifetimes than red stars. These stars have had less time for gravity to draw them to the galaxy center. These are the hottest type of stars.
Orange star
5th hottest, 3500F-5000F, Aldebaren and Arcturus
Eclipsed sun
This one is tricky... so I'm going to save you the frustration at tell you that it's an "Eclipsed Sun"
Lunar Eclipse
An eclipse where the Earth comes between the Sun and the Moon and it is a full Moon (the moon is covered, has a shadow of dark red cast on it, or slightly dimmed)
Solar Eclipse
This occurs when the moon is between the Earth and the sun... and no, it is not a new moon.
Nebula
A large cloud of gas and dust in space, spread out in an immense volume
Star Cluster
A large grouping of stars, from a few dozen to a few hundred thousand, that are bound together by their mutual gravitational attraction.
