Across
- 1. Dark spots that are visible on the surface of the sun that are caused by intense magnetic activity that disrupts convection forming areas of reduced surface temperature
- 3. Equipment used to magnify objects far away.
- 5. This occurs when the Moon passes between the Sun and the Earth so that the Sun is completely or partially obscured.
- 7. This is a natural satellite that orbits a planet or smaller body.
- 8. This is the tide that occurs twice a month, when the difference between high and low tide is least; the lowest level of high tide.
- 11. This is an arc of gas that erupts from the surface of the Sun (also called a filament) which can loop hundreds of thousands of miles into space.
- 14. These are caused by the gravitational pull of the moon.
- 15. This is the distance that a light travels in 365.25 earth days.
- 16. One of four major divisions of the year based on the Earth's tilt and the light from the sun.
- 17. The layer of the Sun above the chromosphere which is hotter than the Sun's surface.
- 18. This occurs when the Moon passes through some portion of the Earth's shadow. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely.
- 19. This is a massive, gravitationally bound system consisting of stars, interstellar gas and dust, and dark matter.
- 20. This is the very high and low tides that occur during the new moon or the full moon when the sun, moon, and earth are approximately aligned.
- 22. This is an attractive force between any two objects due to mass.
- 23. This is a massive ball of plasma that shines because of thermonuclear fusion in its core.
Down
- 1. A specially designed robotic space vehicle designed to explore various aspects of the solar system.
- 2. This is an instrument used to analyze the component parts of a sample by separating its parts into a color spectrum.
- 4. This is the Sun and the celestial objects bound to it by gravity.
- 6. This is the star at the center of the solar system around which the Earth and other matter orbit.
- 9. A large, rocky body found in space. It often orbits the sun in a belt between Mars and Jupiter.
- 10. The third planet from the sun.
- 12. This is the distance between the sun and the earth. It is the standard unit for distance within our solar system.
- 13. This is the visible event that occurs when an asteroid enters Earth's atmosphere and becomes visible.
- 21. This is a celestial body in orbit around a star.
