Across
- 7. First apparent contact between the moons disc and the suns disc.
- 9. Cause of 'fast solar wind' of charged particles
- 10. Filter for telescope to allow observation of the sun.
- 12. Stream of charged particles from the Sun's corona. Causes Aurorae on Earth
- 14. Equation used to calculate the likelihood of intelligent life in the galaxy
- 16. Average distance from Sun to Earth (150 million km)
- 17. Volcanic moon of Jupiter. Heated by tidal forces.
- 18. Region on earth that will observe a total eclipse when the moon passes in front of the sun
- 19. Less dark, slightly hotter part of a sunspot
- 20. Straight blue tail caused by excited ions
- 22. Darker, cooler region of a sunspot
- 23. Time it takes for the moon to rotate on it's axis once. A sidereal month
Down
- 1. Plane that the earth and other planets orbit the sun
- 2. Caused by earth passing through the tail of a comet. E.g. Perseids
- 3. Where on the sun do sunspots appear
- 4. The fusion series that takes place in the sun
- 5. Part of the suns atmosphere only visible during a total eclipse
- 6. Mars' two moons, likely captured asteroids
- 8. Increase in heat caused by the different gravitational force on a body in orbit
- 11. Unusual moon of Neptune. Will ultimately be broken up by tidal forces
- 13. Region on earth where the sun will look as if a bite has been taken out of it.
- 14. Curved tail on a comet caused by dust pushed off the comet by the radiation pressure
- 15. Coloured Lights in the night sky found at high latitudes
- 21. One way in which exoplanets are discovered. The planet passes in front of it's parent star
- 23. Time interval between full moons. A synodic month
- 24. Belt, Ring of rocks between the orbits of Mars and Jupiter
