Cepheid variable stars have masses much larger than our Sun; the more massive stars are more luminous and have more extended envelopes 10. The stars near the centers of galaxies are orbiting at high velocities, which mean that there is the presence of super-massive black holes in the centers of most galaxies. 11. Large galaxies can absorb smaller galaxies called galactic cannibalism. Chapter 14 1.
Prominences 1. Prominences are immense clouds of glowing gases that erupt from the upper chromosphere. 2. The loops or arches of gases may shoot as high as 100 000 kilometres from the surface of the Sun. This allows some of the surface gases, mainly hydrogen and helium, to escape into space.
Describe two ways in which gravity has a part in the life-cycle of a star- Gravity pulls the dust and gas in the nubula together, and compresses them so much that the inside becomes hot enough for fusion reactions to start. Gravity also pulls the remains of a red giant together after fusion reactions have stops. This forms a white dwarf. Theories about the universe- 1. What does red shift tell s about distant galaxies?

How did Hubble discover it? Hubble's LAW says that the universe is expanding and the further galaxies are traveling faster away then the closer galaxies. How does the abundance of light elements provide support for the big bang picture of the universe? It shows the first elements of our universe hydrogen helium and lithium was formed 3 minutes after the bis bang. Is the universe getting warmer or colder?
1 AU b. 149,600,000 km c. 8.3 light-minutes d. all of the above 5. Distances between stars are usually measured in a. light-minutes b. astronomical units c. light-days d. light-years 6. Einstein developed an equation that changed ideas about the sun’s energy source by describing the relationship between a. mass and energy b. gravity
The idea could be considered as madness but others may say THIS IS PHYICS!  After the giant nebula has started to converge it forms a Protostar, this Protostar is halfway between a nebula and a star. Eventually it gets to a point where it cant contract any more gas and the tremendous pressure starts to cause tremendous hear, and thus nuclear fusion begins, true story. 
limb_flare_sm.jpg (5710 bytes)Solar flares are tremendous explosions on the surface of the Sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons of TNT. They occur near sunspots, usually along the dividing line (neutral line) between areas of oppositely directed magnetic fields. The biological effect. There is a growing body of evidence that changes in the geomagnetic field affect biological systems.
(2 points) Mars. B) Cosmic Origin of the Element CLUE: The substance collected has properties indicating that it contains a few different elements. The elements in your sample were formed in a supernova and released into space when the star exploded. Small stars and cosmic rays are not hot enough to form them. Look at the chart below to see which elements are typically formed in supernova and which ones are not.
These two stars are thought to be cooling and expanding on their way to becoming red giants. The second pair, around 10,000 astronomical units from the first, consists of two faint, small and relatively cool red dwarfs. The Capella
