super black hole-It is said that a super black hole is in the center of the milky way galaxy and will waken up once the sun dies(explodes)
The Milky Way-is a barred spiral galaxy, about 100,000 light-years across. If you could look down on it from the top, you would see a central bulge surrounded by four large spiral arms that wrap around it.
Planet-An object that orbits a star. Although smaller than stars, planets are relatively large and shine only by reflected light. Planets are made up mostly of rock or gas, with a small, solid core. In our solar system, the inner planets (Mercury, Venus, Earth, and Mars) are the rocky objects, and the outer planets (Jupiter, Saturn, Uranus, and Neptune) are the gaseous ones.
Comet-A ball of rock and ice, often referred to as a "dirty snowball." Typically a few kilometers in diameter, comets orbit the Sun in paths that either allow them to pass by the Sun only once or that repeatedly bring them through the solar system (as in the 76-year orbit of Halley's Comet). A comet's "signature" long, glowing tail is formed when the Sun's heat warms the coma or nucleus, which releases vapors into space.
Constellation-A geometric pattern of bright stars that appears grouped in the sky. Ancient observers named many constellations after gods, heroes, animals, and mythological beings and people that may not be important. It is that when a loved one passes away, they become one with the stars just like all the ancestors. Leo (the Lion) is one example of the 88 constellations. and Virgo(the madien) is a constellation as well.
Dark Energy:A mysterious force that seems to work opposite to that of gravity and makes the universe expand at a faster pace
Dark Matter:Matter that is too dim to be detected by telescopes. Astronomers infer its existence by measuring its gravitational influence. Dark matter makes up most of the total mass of the universe
