Bad Astronomy.

The project i would like to do is called How Do We Know? I would like to do this project because i would like  to know more about the sky and astronomy. I am interested in the constellations.

1. Bad Moon Rising. Did we really land on the moon?
a. Before this website, i figured we did land on the moon, but i didnt know, just like many people didnt know because we were not there.
b. The website says, yes we did land on the moon, so i didnt really learn much. I did learn on reason for thinking it was faked was that the pressure due to the Cold War forced the government to fake it.

2. The Sky At Night. Do All Stars Look White?
a. I think that most stars look white, but the dying ones, and special other cases, make them change colors.
b. I didnt know that stars emit all colors of the rainbow, i thought only white, red, and yellowish. I also learned that the stars change colors because they change temperatures. If the star is very hot, its glows blue. If a star is not so hot, it glows red.

3. A Step Farther Out. Whats Your Sign?
a. My sign is Aquarius. There is 12 signs, that align with each month.
b. There is really 13 to 24 zodiac signs. As in there is more constellations, but there is 12 zodiac signs. Scorpio is really called Scorpius. Capricorn is really named Capricornus.

Hubble Site Posting.

1. Using the x-ray viewer, i found the sun, and the milky way center.
The Sun is 93 million miles away from the Earth. The Sun is half-way through its lifespan of 10 billion years. It is not a black hole.
The milky way center 28,000 lightyears away. It is a supermassive black hole. The black hole reveals itself in x-ray and radio images.
Using visible light, i saw M33.
M33 is a stellar mass black hole. It is 2.1 million lightyears away. Many of the million stellar mass black holes are visible to us.
Using the radio waves, i saw Betelgeuse and the Moon.
The moon 240,000 miles away from the Earth. It is not a black hole. It is Earths companion, it orbits around us once a month. Betelgeuse, also known as the red giant, is not a black hole. It is 430 lightyears away. It is too distant away to see in a x-ray image. All stars become a red giant late in life.


2. During the voyage to Cygnus-X1, we passed the moon, and all the planets. Then went past the Nebula's, the Ring Nebula, Dumbbell Nebula. Then we got to Cygnus-x1, which is a binary system where a stellar mass black hole pulls gas out of a star that orbits around it.
Then came the voyage to Andromeda, a black hole in a spiral galaxy million lightyears away from the Earth. The black hole inside the galaxy is thirty million times heavier than the  Sun.  On the way to the galaxy, we passed everything we passed on the voyage to Cygnus-x1. The only difference was that we had to go a little farther.


3. What is a black hole? A black hole is an object that is so compact that its gravitational force is so strong no light or anything else can escape it.
 
Do black holes live forever? Yes, black holes can evaporate, and return their energy to the universe. (Stephen Hawking proved this in 1974)


Do black holes obey the laws of gravity? Yes, they obey all laws of physics, including the laws of gravity. The black hole is a direct consequence of gravity.

FIRST POST. :)

I would like to learn about the technology used in solar panels. I'd like to see how to make one, and put it together. Also, i would like to learn more about wind energy, and other kinds of energy and how to store it. The internet i already know quite a bit about, but not on a mac. I would like to see how water treatment plants work. Also, how people think of these new ideas.
