Let me say this: yours has been my favorite Astronomy class since I started teaching it. Thank you for showing interest, for coming to class regularly, for asking questions, for studying for your tests, and for doing well on your capstone projects. I hope you will take an astronomy class in college. They are fun, and the professor will actually have a degree in astrophysics, so they might know all the details. I don't know all the details, but I do know I like astronomy very much.
Good luck. Dr. F
Presentations are still going. . The Final Exam next week will be reviewed on Friday, don't miss it.
Astronomy FINAL EXAM ISM Dr. Fisher
These are brief questions that require long and detailed answers. The more information you give me on that topic, the better will be your score.
Answer all questions.
Put one question per page, with the question number at the top of the page
You should have at least ½ page of text with each answer.
In each case, I’ve posed some questions, but your answer should include what you know on that topic.
When I say “explain”, it means identify key components and how they act or interact.
When possible, use diagrams, sketches, labels, arrows, and descriptive phrases or lists as appropriate.
Use multiple colors to make your diagrams clear
Write neatly and carefully; I can only grade what I can read.
Take your time. You have two hours. You will be required to stay for two hours.
Each question is worth 20 points.
example: Describe how our own planet formed. Explain our overall composition (iron, silica, water, carbon), why the core is iron, why we have a magnetosphere, why we have an atmosphere, why our atmosphere is the composition it is, why we need a greenhouse effect but not too much, why we have tectonic activity, and other points. Explain why mercury has no atmosphere and the outer planets are mostly gas.
example: Describe how to make a galaxy. Include a sketch. Then show what our own galaxy looks like today, with labels to all the main parts, and show the distance in LY of 3 dimensions.
this first sentence is very short, and the answer is long. Create that answer to practice.

On Feb 22, 1632, Galileo published Dialogue Concerning the Two Chief World Systems in which he argued against the belief of the church, that the Earth was not the center of the Universe, and that in fact the Sun is the center of the solar system, and the Earth is circling around it. The Dialogue was placed on the Catholic Church's Index of Forbidden Books the following year, and Galileo was tried and convicted for heresy. He spent the rest of his life under house arrest, and none of his later books were permitted to be published in his lifetime. The Dialogue remained on the Index of Forbidden Books until 1835.

The whole symphony is worth all 49 minutes. I listen to it while I'm grading Astronomy finals.
"The Planets", Op. 32, is a seven-movement orchestral suite by the English composer Gustav Holst, written between 1914 and 1916. Each movement of the suite is named after a planet of the Solar System and its corresponding astrological character as defined by Holst. With the exception of Earth, which is not observed in astrological practice, all the planets are represented. The idea of the work was suggested to Holst by Clifford Bax, who introduced him to astrology when the two were part of a small group of English artists holidaying in Majorca in the spring of 1913; Holst became quite a devotee of the subject, and liked to cast his friends' horoscopes for fun. The suite has seven movements, each named after a planet and its corresponding astrological character: 1. Mars, the Bringer of War 2. Venus, the Bringer of Peace 3. Mercury, the Winged Messenger 4. Jupiter, the Bringer of Jollity 5. Saturn, the Bringer of Old Age 6. Uranus, the Magician 7. Neptune, the Mystic Holst's original title (clearly seen on the handwritten full score) was "Seven Pieces for Large Orchestra". he orchestral premiere of The Planets suite, conducted at Holst's request by Adrian Boult, was held at short notice on 29 September 1918, during the last weeks of World War I, in the Queen's Hall with the financial support of Holst's friend and fellow composer Henry Balfour Gardiner. It was hastily rehearsed; the musicians of the Queen's Hall Orchestra first saw the complicated music only two hours before the performance, and the choir for "Neptune" was recruited from pupils from St Paul's Girls' School (where Holst taught). It was a comparatively intimate affair, attended by around 250 invited associates, but Holst regarded it as the public premiere, inscribing Boult's copy of the score, "This copy is the property of Adrian Boult who first caused the Planets to shine in public and thereby earned the gratitude of Gustav Holst."

Oct 8 was the birthday of astronomer Neil deGrasse Tyson (1958). He was born and raised in New York City and was interested in space from a young age, but in his Bronx neighborhood, African-American boys earned respect for athletic prowess rather than book smarts. Undeterred, he studied astronomy on his own, and was giving lectures on the subject when he was 15.
He's described himself as a "passionate agnostic," and has collaborated with evolutionary biologist and staunch atheist Richard Dawkins on discussions of religion and science. He's received his fair share of hate mail, but not because of his critique of religion: He spearheaded the controversial movement to have Pluto downgraded from full planet to dwarf planet status, something that the younger generation of astronomy buffs apparently found intolerable. Most of the hate mail came from schoolchildren.
He wrote: "I don't care what else anyone has ever told you, the Sun is white, not yellow. Human color perception is a complicated business, but if the Sun were yellow, like a yellow lightbulb, then white stuff such as snow would reflect this light and appear yellow — a snow condition confirmed to happen only near fire hydrants."

October ends with an astronomy-based holiday. Halloween began as the Celtic holiday of Samhain (rhymes with HOW-when). It marked the start of the dark half of the year, which ended on May Day—or, as it is still sometimes called, Beltane. On Samhain, the evil spirits that had been cooped up for six months broke loose and lived it up—i.e., they wreaked havoc. So people tried to appease them with offerings of food and used gourd lanterns to ward them away. These traditions survive as trick-or-treating and jack o' lanterns. From http://www.astro.umn.edu/outreach/starwatch/current.html
