1. The first extrasolar planets  discovered were a pair of rocky objects orbiting PSR B1257+12, a [|pulsar] in the constellation of Virgo, 980 light-years from the Earth. Radio astronomers Aleksander Wolszczan (Polish) and Dale Frail (Canadian) were credited with the find, which was announced in 1992 and quickly confirmed. 2. October 6, 1995 using velocity method 3. 51 Pegasi B about 51 light years away. Its mass is a little more than our sun's mass with a solar mass of 1.06. This planet is a large gas planet. 4. 5. I think our next step is finding ways to get to the "next earth" planet. Like bigger and better spacecrafts that people can live in for years and survive and have families. This will probably take a long, long time since we would need more advance technology than what we have now and people that still have yet to invent things to help with this.

an earthquake with the magnitude 6.3 struck the Christchurch region on February 22 in New Zealand
 * **Magnitude** || a. Describe the magnitude of this earthquake

b. Explain what "magnitude" means. (the scale used, and how a 3 on the scale differs from 2, 4, etc.) a [|number] assigned to the ratio of two quantities; two quantities are of the [|same] order of magnitude if one is less than 10 times as [|large] as the other; the [|number] of magnitudes that the quantities differ is specified to within a [|power] of 10 || death toll is up to 169 found but estimates say there are still more, up to 240 dead total, costs range from 6 to 12 billion dollars || The earthquakes in New Zealand are due to plate boundary forces. yes ||
 * **Impact** || Explain damage, cost, death toll, etc.
 * **Cause** || a. Why did the quake happen where it did? Does this region get a lot of quakes?
