Across
- 1. A loop of gas that protrudes from the sun's surface, linking parts of sunspot regions
- 4. the small, dense remains of a high-mass star after a supernova
- 6. A continuous stream of charged particles from the Sun
- 8. A small, hot, dim star that is the leftover center of an old star
- 9. A gigantic explosion in which a massive star collapses and throws its outer layers into space
- 11. This region is where hot gas travels upward while cooler gas travels down
- 12. Time when the Sun is farthest from the equator.
- 16. A contracting cloud of gas and dust with enough mass to form a star
- 19. eclipse occurs when the Moon passes directly between the Sun and Earth and casts a shadow over part of Earth
- 20. An object in space whose gravity is so strong not even light can escape.
- 21. A large cloud of dust and gas in space

Down
- 2. The orange-red portion of the star
- 3. This process known as nuclear ____ occurs when atoms are merged together
- 5. eclipse occurs when the blocking of sunlight to the moon that occurs when Earth is directly between the sun and the moon
- 7. This region of the star is where the energy from the center travels outward from atom to atom
- 10. When the prominence escapes the sun it becomes a coronal mass ejection
- 13. A dark area of gas on the sun's surface that is cooler than surrounding gases.
- 14. The central region of a star where fusion is occurring
- 15. the phase where less of the Moon's near side is lit each night
- 16. The 'Surface' of the star that we see which is gas
- 17. Violent eruptions of particles and radiation from the surface of the Sun
