Planet Quest
1. What are the four ways scientists can detect planets?
- Radial Velocity, Astrometry, Transit Method, Optical Ditection.

2. Which way makes the most sense to you? Explain it.
- Radial Velocity because it measures the position of the star as it is tugged back and forth by gravitational pull.

The Goldilocks Zone
3. Explain the concept of the "Goldilocks Zone."
- It is the area of space in which a planet is a perfect distance away from its home star so that it is not too hot or too cold.

4. If Gilese 581c does have life, what do you think it would look like? How would it act? Would it be intelligent?
- I think life on Gilese 581c would have developed to water because it could most likely be covered with oceans. So they would probably look like fish. Since the grivitational pull is almost twice of Earths then it would be putting more pressure on the things on the planet, so whatever life is there it would be kinda flat i guess.

5. Do you believe in aliens? Why or why not? Give me a solid paragraph.
- I do believe in aliens because we have developed from something else and addapted to our environment. So it culd be very much possible for there to be life on other planets that have developed from something else and addapted to their environment. They may not have the same qualities as we do or the same environment but that is just they place they started in so they learned how to live in it.

1. What is the primary gas in the Jovian atmospheres?
- Hydrogen

2. What is the primary gas in Mars and Venus?
- Carbon dioxide

3. If you had to visit one planet, which would it be? Why? Give me a solid paragraph. (consider many factors such as location, temperature, atmosphere composition, and anything else you you feel is important)
- i would probably like to visit Saturn because it has helium and hydrogen. I also like saaturn because it is super cold. I think it would be cool because it has rings around it and is the second largest planet.

Black holes- are the evolutionary endpoints of stars at least 10 to 15 times as massive as the Sun. If a star that massive or larger undergoes a supernova explosion, it may leave behind a fairly massive burned out stellar remnant. With no outward forces to oppose gravitational forces, the remnant will collapse in on itself. The star eventually collapses to the point of zero volume and infinite density.

Worm holes- A hypothetical "tunnel" connecting two different points in space such a way that a trip through the wormhole could take much less time than a journey between the same starting and ending points in normal space. The ends of a wormhole could, in theory, be intra-universe.

Dark energy- In the context of dark energy, the cosmological constant is a reservoir which stores energy. Its energy scales as the Universe expands. Applied to the supernova data, it would distinguish effects due to the matter in the Universe from those due to the dark energy. Unfortunately, the amount of this stored energy required is far more than observed and would result in very fast acceleration. So much so that the stars and galaxies would not form.

Titan- Titan is the largest moon of Saturn and the second largest moon in the solar system. Astronomers suspected that Titan might have an atmosphere. Scientists also believed they might find liquid seas or pools of methane meaning water would be frozen due to Titan's low surface temperature.

Pluto- is a dwarf planet that orbits far from the sun. It shares the region of its orbit with the Kuiper belt. From its discovery in 1930, people widely considered Pluto to be the ninth planet of our solar system. However, because of its small size and irregular orbit, many astronomers questioned whether Pluto should be grouped with worlds like Earth and Jupiter. astronomers now classify Pluto as a dwarf planet. Pluto cannot be seen without a telescope.

1. Which blog was your best this quarter? Why?

- i think my best blog thssis quarter was the one about an environmental issue because it had reasons why it was a problem the causes and tyhe effects it has on us. also it has solutions.

2. What topic did you enjoy learning about the most (from chapter 17-20)? Why? Include a picture.

- i like the part about the green house effect because i never understood how the earth was getting warmer.

3. What grade do you deserve for your 3rd Quarter Blogs? (Keep in mind some basic math. If you only did 3 out of 6 of them you cannot earn above a 50%.)

- i think i should get a hundred because all of my blogs are completed and done correctly.

1. Check out Fayetteville's pollen forecast. Which is affecting us the most right now: tree, grass, or weed pollen? Specifically, which trees, grasses, or weeds?

- Oak trees.

2. "You're Surrounded by Pollen," so read this article. What is needed for a "perfect storm" of pollen?

- Compressed flower season with dry and windy weather.

3. Choose a microscopic image of pollen. Which one looks the best to you? Why? Where is this pollen commonly found? Write a paragraph in your own words explaining this specific type of pollen. Include a cool-looking picture. You may need to use other websites to help you.

- I think the penta anther looks the coolest because it looks spungier that the others. It is commonly found in flowers and transferred to other flowers by insects.

The penta anther pollen when put in other flowers stores more pollen and lets it out later when it is full. This is a big cause of pollination. It has pores which it stores other things and lets them back out.

1. What are the five states of matter?
- solid, liquid, gases, plasmas.
2. What is needed to change a gas into a plasma?
- add heat.
3. What is the temperature at "absolute zero?" (in Farenheit, Celsius, and Kelvin)
- K= 0., °C= -273.15, °F = -459.67
4. What is the temperature in space? (in Kelvin)
- 3K
5. What do you think plasma would like look/smell/feel/taste? How about Bose-Einstein Condensates? Do some research on other sites, but ultimately come up with your own unique answer :)
- look like florecent light, smell like whatever is in it, feels hot, taste like a light bulb duh!
