25 Questions

1. A cycle of rise and drop in the ocean; caused be the gravitational pull of the Earth - Sun - and Moon.

2. Almost directly over the North Pole - and does not seem to move at all. If the star rises perpendicular to the horizon - the observer is standing on the equator

3. 23.56 hours

4. The blocking of sunlight to the moon that occurs when Earth is directly between the sun and the moon

5. Jets of hot gas that extend from the Sun to around 20 -000 kilometers beyond the photosphere.

6. Apparent motion of the planets when they appear to move backwards (westward) with respect to the stars from the direction that they move ordinarily.

7. How long does it take for Earth to orbit the sun?

8. Occurs when the Moon passes directly between the Sun and Earth and casts a shadow over part of Earth

9. When the Sun becomes a Red Giant - 10 billion years - Then a White Dwarf - aproximately 12 billion years

10. 29.5 days

11. Moon phase that occurs when the Moon is between Earth and the Sun - at which point the Moon cannot be seen because its lighted half is facing the Sun and its dark side faces Earth

12. Remnant radiation from the big bang - which we detect using radio telescopes

13. The sun and stars move across the sky because of this - the stars rotate around Polaris - the North Star and make a complete circle around Polaris.

14. Only one side

15. A gathering of roughly 30 Galaxies in which the Milky way belongs

16. A galaxy that does not fit into any other category;

17. Imaginary great circle on the surface of the earth passing through the north and south poles at right angles to the equator

18. Point above the observer that is directly opposite the nadir on the imaginary sphere against which celestial bodies appear to be projected

19. 1. Mass-Energy Equivalence (when a body has a mass it has a certain energy even if not moving); 2. General Relativity (gravitational attraction between masses is a result of the nearby masses. gravity has waves.)

20. The universe originated 13.7 billion years ago from the cataclysmic explosion of a small mass of matter at extremely high density and temperature helium was present - universe is expanding and cooling

21. The Milky way observed through a cross section - Our solar system is 27 -000 light years away from the Galactic bulge

22. Bright regions seen in the solar chromosphere

23. Alpha Centauri - 4.37 light years away OR Proxima Centauri - 4.24 light years away

24. 4.5 billion years

25. Imaginary sphere surrounding Earth on which celestial bodies are projected.
