Nebula- a cloud of gas and dust in outer space
Protostar- a contracting mass of gas which represents the early stage of formation in a star
White Dwarf- a stellar remnant composed mostly of electron-degenerate matter
Supernova- transient astromnical event that occurs during th last stellar evolutionary stages of a massive star's life
Neutron Stars- a type of compact star
Pulsar- a highly magnetized rotating neutron star
Black Hole- a region of space-time exhibiting so much gravitational effects that nothing can escape from inside it
Spiral Galaxy- flat, rotating disc containing stars, gas, and dust
Barred-spiral Galaxy- central bar-shaped structure composed of stars
Irregular Galaxy- a galaxy with no distinct, or regular shape
Quasar- a massive and extremely remote celestial object, emitting large amounts of energy      
The Big Bang Theory- a cosmological model that explains the early development of the universe 
Dark Matter- a hypothetical substance that is believed by most astronomers 
Dark Energy- unknown form of energy which is hypothesized to permate all of space

Nebula - A type of cloud which is made from gas and "space" dust

Protostar - Basically the early version of a star

White Dwarf - A white planet-sized star has nearly used up its power

SuperNova - A star that has exploded

Neutron Stars - IDK sorry =/

Black hole - An invisible hole that has a very strong gravitational field capable of trapping light

Spiral Galaxy - A galaxy shaped like a spiral

Barred-spiral galaxies - Just like a spiral galaxy but this time it also has a bar-shaped cluster of stars

irregular galaxy - A galaxy with no distinctive shape

Quasar - A big object containing massive amounts of energy

The Big Bang Theory - The theory of our universe being created by a big bang

Dark matter - Type of matter that is dark (non-emitting light) and is thought to be in space

Dark energy - Something which is thought to make the universe expand
