Wiki Assignment 3: The Search for Habitable ("Earth-like") Planets Background: Before the 1990's most scientists didn't think we would ever find planets outside of our own solar system, let alone potentially habitable "Earth-like" planets. Since then, some truly amazing discoveries have been made. This topic is truly cutting edge in Astronomy and all of science!

Directions: Conduct some research on this topic and type a short summary on your wiki. I want to give you some creative freedom in terms of direction here, but at the bare minimum you should seek answers to the following questions


 * 1) 1. Who were some of the first people to find an "extra-solar" planet (a planet beyond our own solar system)?Bruce cambel discovered the first planet in an extra solar system.
 * 2) How and when were these scientists able to make such an amazing discovery?:october 6th 1995, using the radi velocity method.
 * 3) What do we know about these planets? How far are they from Earth? What do scientists think these first discovered extra-solar planets are like in terms of (size, composition, conditions, etc.)?:51 peqasi b.
 * 4) Provide a short time line of events/discoveries that have been made since then. There was the martin landscape, and many more planets, stars were found.
 * 5) Based on what you have learned so far, predict where you think this research will lead? (i.e. what will scientists learn about extra-solar planets in the future or what is the next step in this area of study?) It would also be a good idea to mention some of the problems, obstacles, etc. that will need to be overcome.think that this research will lead to more tech stuff, and improve the way we currently live.

|| b. Explain what "magnitude" means. (the scale used, and how a 3 on the scale differs from 2, 4, etc.)//magnitude of an earthquake// is determined from the logarithm of the amplitude of waves recorded by seismographs ||
 * || This rock is Diorite. || [[image:file:///Users/13yagerhot/Desktop/images.jpg]][[image:images.jpg width="172" height="141"]][[image:file:///Users/13yagerhot/Desktop/images.jpg]] ||
 * It is composed of these chief rock forming minerals || [[image:http://www.mii.org/Minerals/Minpics1/Potash%20feldspar.jpg width="208" height="187" caption="external image Potash%20feldspar.jpg"]][[image:http://www.es.ucl.ac.uk/schools/Glossary/biotite.jpg width="244" height="189" caption="external image biotite.jpg"]]
 * Process by which it forms || [[image:http://atschool.eduweb.co.uk/arbrahs/materials/science/images/volcano01.jpg width="402" height="255" caption="external image volcano01.jpg"]] ||
 * short explanation || Diorite forms deep in the earth's crust from cooling magma - just like granite. But, the magma does not contain a lot of quartz or the light colored minerals that make up the granite. Instead it contains only dark colored minerals. ||  ||
 * **Magnitude** || a. Describe the magnitude of this earthquake 7.0
 * **Impact** || Explain damage, cost, death toll, etc.houses,schools,buildings destroyed. $12billon dollars. the death toll was estimated at 300 people ||
 * **Cause** || Why did the quake happen where it did? Does this region get a lot of quakes? it happend due to the climate temp, and the air surface. the region doesnt get that many quakes at all. ||
