The Sun and Stars

1. A red super giant star explodes
6. 4th state of matter, made up of superheated gas with a positive electrical charge
7. exerts such a strong gravitational pull that no light escapes
8. the earliest stage of a star's life
10. A reaction in which two or more atomic nuclei are combined and a vast amount of energy is released
11. Violent explosion on the surface of the sun that releases a large amount of energy and interrupts the sun’s magnetic field
13. The visible surface of the sun, the region that emits sunlight (6,700oC)
15. Thin layer of the sun’s atmosphere glows red and heated by the photosphere 4,000-10,000oC
16. Layer of the sun just outside of the core temperatures are about 7million oC
17. a large cloud of gas and dust in space

2. A particle of light
3. The remains of a high mass star
4. what a medium-mass star becomes at the end of its life
5. The outermost layer of the sun’s atmosphere (2-5millionoC) also known as the sun’s halo or crown
9. plasma flows along a loop of the Sun’s magnetic field from sunspot to sunspot, it forms a glowing arch that reaches thousands of km into the sun’s atmosphere
12. The outermost layer of the interior of the sun, hot material from the radiative zone rises, cools at the surface, then plunges back to the radiative zone
14. star left at the core of a planetary nebula
