The 4 ways scientists can detect planets are radial velocity, Astrometry, Transit Method, Optical Detection.
Astrometry makes more sense because it give you the precise measurement of the position of the stars. It tells you the stars motion and from that scientists can figure out the orbit and mass of it.
The Goldilocks Zone is called the life zone. It is the area where the planet is just the right distance from its home star and its surface is not hot or cold. This means that the planet could possibly have water.
If the Gilese 581c had life on it I think they would look like fish because it might be covered in water. I think they would act weird because their planet has twice as much gravity as Earth and that they live in water. I do not think they would be intelligent because they live in water.
I do not believe in aliens because the whole idea of them is crazy. No one has ever seen them before and where would they live. I am sure that Scientists have looked at all the planets by now and if there were really aliens out there they would have seen something. If there were really aliens I think they would have come to Earth by now or did something to show us that they were real.

Planets
1. The primary gas in the Jovian Planets is Hydrogen.
2. The primary gas in Mars and Venus is Carbon Dioxide
If I could visit one planet it would be Saturn because I would like to see its rings. I know that they are made of water ice and dust material so I would like to know what they feel like and see how thin they really are. I would also like to see the second biggest moon Titan and see what Saturn looks like sense it is mostly gas.

Astronomy
Saturn's rings are made of water and ice. The ring are divided into 7 divisions which are D,C,B,A,F,G, and E. F and G are very thin and difficult to see and the A,B, and C rings are more visible. Between the A and B rings are a gap called the Cassini division which was named after Giovanni Cassini who discovered it. Between the A and F rings is a gap called the Keeler gap.
A black hole is a place in space where nothing including light can escape. It is called black because it absorbs all light that hits it and reflects none of it. The black hole's energy bends light. Its interior is invisible and can only be seen by its interaction with other objects. Around the black hole is an event horizon where matter and light can only go inwards.
The Milky way is the galaxy where the solar system is. It is a barred spiral galaxy that is part of the Local Group of galaxies. The sun revovles around the center of the galaxy. The Milky way has a bulge, disk, and a halo. The halo and bulge contain old stars and the disk is filled with new stars, gas, and dust. The galaxy is at least 5 billion years old.
Mars if the fourth planet away from the sun. It is called the " red Planet" because of its reddish appearance. It is a terrestrial planet and has a thin atmosphere. Mars has the largest mountain in the solar system which is Olympus Mons and the largest canyon which is called Valles Marineris. It has 2 moons called Phobos and Deimos and they are both small and ireegularly shaped.
Titan is the largest moon of Saturn and the second largest in the solar system. Titan is classified as a moon, but is larger than Mercury and Pluto. It has a planet like atmosphere ans is more dense than Mercury, Earth, Mars and Pluto. It is mainly made up of nitrogen and other elements.

3rd quarter blogs
My best blog was the wordle because I like doing the wordle and I get to be creative with it.
The topic that I enjoyed the most was the clouds because it was an easy chapter and I understood everything about it.
I think that I deserve a 100 for my 3rd quarter blogs.

Pollen
1. Tree pollen is affecting us the most right now. Pine and oak trees are where we are getting most of the pollen.
2. For a perfect storm of pollen the weather needs to be dry and windy.
3. I chose the Convolvulaceae pollen(Ipomoea purpurea)because it looks spiky and big. This pollen is commonly found in morning glory flowers. It is divided into 2 subfamilies which are smooth-surfaced and spiny-surfaced.

Matter
1. The five states of matter is solids, liquids, gases, plasmas, and Bose Einstein condensates.
2. To change gas into plasma you need to add more energy to the gas.
3. The temperature at absolute zero for fahrenheit is -459.67, for Celsius it is -273.15, and for Kelvin it is 0.
4. The temperature in space is 3K
5. I think that plasma would look very bright and shiny. It would look like the color of what was around or inside of it. I think it will feel very hot and it would smell like electricity. I do not think that it would have a taste, it would just feel very hot on your tongue.
