| radiowaves | | Type of telescope that uses a convex lens |
| Hubble | | Galaxies that have no regular shape |
| reflecting | | The wave with the longest wavelength on the electromagnetic spectrum |
| Electromagneticradiation | | When as star is moving towards the Earth, its wavelength shortens, when this happens the spectrum shifts towards this color. |
| Gammarays | | A lens that is thicker in the middle than at the edges |
| Refracting | | Our galaxy |
| red | | Visible light has a very ____________ wavelength |
| Wavelength | | Distance between the crest of one wave and the crest of the next wave |
| Galaxy | | Type of telescope that uses a mirror |
| Observatory | | A device used to detect radio waves from objects in space |
| Milkyway | | A building with one or more telescopes |
| Night | | Patterns of stars in the sky |
| Nebula | | Light you can see with you eyes |
| Spectrograph | | A reflecting telescope that orbits the Earth |
| Binary Star | | A cluster of hundreds of billions of stars |
| Spiral | | All space and everything in it. |
| Elliptical | | When do most astronomers have to work |
| Short | | Start system with two stars |
| radiotelescope | | The wave with the shortest wavelength on the electromagnetic spectrum |
| Irregular | | Our Star |
| Blue | | When as star is moving away from Earth, its wavelength lengthens, when this happens the spectrum shifts towards this color. |
| Visiblelight | | Most stars are composed of 73% of this element |
| Hydrogen | | The birth of the universe |
