Apparent Magnitude | a property that describes how bright the star looks to an observer on Earth |
Blue Star | This is the hottest type of star |
Absolute magnitude | describes the true brightness of a star, if they were all viewed from the same distance |
Yellow Star | This is type of star has a medium temperature |
Radiation Zone | part of the Sun where energy travels from the center of the sun to the surface |
Convection Zone | The surface layer of the Sun where hot gas rises to the surface, then cools and sinks |
Core | The part of the Sun where nuclear fusion combines hydrogen atoms into helium. |
Red Star | This is the coolest type of star. |
Corona | A part of the Sun's atmosphere that is visible during an eclipse. |
Solar Flare | A bright sudden eruption of hot hydrogen gas in the sun's atmosphere. |
Sun Spot | A relatively cool area on the sun's photosphere |
Prominence | A glowing loop of gas which erupts from the surface of the sun. |
Electromagnetic Spectrum | The way we classify wavelengths of energy |
Radio wave | The weakest wave, with the longest wavelength. Used for Wifi. |
Microwave | Used to send cell-phone signals and cook food |
Infrared | Heat. Used in thermal photography |
Visible Light | The wavelengths of energy that you can see. Red, orange, yellow, green, blue, indigo, & violet. |
Ultra Violet | The rays from the sun that can give you sunburn, skin cancer, & cataracts |
X-Rays | These waves pass through skin and muscle, allowing us to take pictures of bones. |
Gamma Rays | The strongest waves with the shortest wavelength. Given off by nuclear reactions. |
