Two Sides to Every Story

By manipulating the number of suitable stars and lowering the numbers of stars that form into planets, it decreased the number of communicating civilizations in our milky way. By increasing the amount of suitable stars and stars that form to planets it increases the amount of possible communicating civilizations in our galaxy.

Black Holes

1) Jets of Gas, Accretion Disk, Event Horizon

2) Black hole is made by gravity and the gravity is so great in a black hole that once something is sucked in it can not return.

3) We observe the effects of the stars and gas that is close to one.

4) The radius of the event horizon around a black hole.

5) Einstein developed the equation that showed the speed of light, but it has been discovered that even objects moving at the speed of light can not escape a black hole.

James Webb Telescope

A) It measures wavelengths from .6-27 micrometers and is designed primarily to see infrared light but can measure some visible light as well.

B) It is a Prototype because it is not set to launch until 2013.

C) Light has not been collected by this telescope yet so they do not know how old the light will be that they collect.

D) It has a 6.5-meter primary mirror as well as several others throughout the telescope. CCD's are not used in this telescope.

Escaping the Sun- Kiera and Abby

1. We didn't see a relationship between the number of layers and the amount of interactions

2. We found that the data was more accurate in the second simulation because it used a larger number of photons and when you used larger numbers your data is bound to be more accurate.

3. As energy increases the wavelength decreases. As the energy increases the number of photons detected somewhat decreases compared to the number of photons detected when the energy was closer to two.

Stellar Spectra

1. Absorption Spectra

2. Closer because when your closer to things they appear to move more than objects that are far away.

3. Time and Brightness

4. Core

5. Magnitude is based on distance and how bright a star is and intensity is how intense the light is that is given off.

Someday I hope to graduate high school and attend a college and maybe become a doctor and hopefully play softball somewhere.
