| A | B |
| Nebula | Huge cloud of dust and gas that stars form from. |
| Blue Star | First star in high mass star cycle. Burns through fuel quickly. |
| Red Giant | Aging star. Cooler than yellow star or |
| Yellow Star | First star in an average star cycle. Lots of fuel |
| White Dwarf | Old, very dense and small star. Gives off some ligt. |
| Black Dwarf | Dead star with no light / Average mass star cycle |
| Supernova | Red Giant explodes. High Mass stars |
| Neutron Star | Very dense, dark. No fuel. Gives off radio waves |
| Black Hole | Gravity wins! Massive star collapses, and light cannot escape |
| Gravity | A force that pulls the star together. |
| Pressure | A force that "pushes out" to keep the star from collapsing |
| Nuclear Fusion | hydrogen+hydrogen=helium+energy |
| The force that always wins! | Gravity |
| Spectroscope | A device that seperates light into a band of colors |
| A group of stars that seem to form a picture | Constellation |
| Light Telescope | A device that gathers light from stars and other objects in space |
| Radio telescope | A device that gathers radio waves from objects in space |
| Space telescope | A satellite in space that collects many wave lengths |
| Magnitude | The brightness of a star |
| Gamma Waves | Shortest wavelength of energy stars release. High Energy. |
| Radio Waves | Largest wavelengths of energy. Low energy |
