How do they change?-when the magnetic fields change they change.
What is the purpose of the m diagram?-it tells where the solar maximums and the solar minimums are.
What is the sunspots cycle?-it is the cycle that they follow-max every 11 years.
Why do they matter to earth?-they change the weather patterns.
When will the next max be?-2010-2012.
How do we study them safely?-telescope
What telescopes work the best?-a telescope with a proper solar filter.

Tycho Brahe...crazy man?...i think not
Tycho Brahe was born in 1546 and he contributed to the world of astronomy by devising a more precise and accurate telescope. he also brought new information to the community about the planets, especially mars. He found out that the orbit of mars was not round but an eclipse. He was an odd man, he reportedly dueled with swords over a dispute about math with is student. He died in 1601.
Phases of the moon
In the book the Scar it is a new moon. In the book Crown of Swords, I think its a waning gibbous moon. In the book Dreamscapes and Nightmares it has a waning crescent moon, and in the book Just a School Project it has a full moon. In the book Where the Wild Things Go it has a waxing gibbous. That concludes my blog...

Keplar
The Keplar man was born in 1571 and died in 1630. He did a whole bunch of stuff like hypothesizing what physical forces caused the planet to move. He was heliocentric and we all know what that means by now. I don't think it was very fair seeings that he stole all the info from his teacher who died. O well
Galileo
Alright, to start, he was a really cool guys plus he was smart. He was heliocentric which meant(once again) he believed that the earth revolved around the sun. Some of his contributions to the astronomy world were, a brand new telescope =), sunspots and some moons of Jupiter. He was born in 1564 and died in 1642.
