Astronomy 101 now has two new graders: Willow Druella and Alex Hasley.
Would you like to win a medal for earning house points by doing assignments? If so, then join the House Points Competition group. The URL is
At the beginning of every month, a new competition opens. Take a screen shot of your profile showing your name, house, number of house points, and the date your screen shot was taken. Use the web site
to get a link to your screen shot. Enter that link as a comment to the collection post for the current month's competition. At the beginning of the next month, I'll look at your wall to see how many points you have then and subtract the number of house points on your screen shot to see how many you earned during that month. I will then post the number of points earned by all those who entered the competition during that month and award a gold medal to the student who has earned the greatest number of points, a silver medal to the one who comes in second and a bronze medal to the one who comes in third. The medals will be posted on the walls of those who earned them for everyone to see how well you did.
The European Space Agency discovered a ring around the dwarf planet Quaorar which is much farther from the planet than a ring should be. Further details can be found on the web site https://www.esa.int/Science_Exploration/Space_Science/Cheops/ESA_s_Cheops_finds_an_unexpected_ring_around_dwarf_planet_Quaoar
This new dwarf planet doesn't count for the question about the total number of moons in orbit around dwarf planets.
Whenever you fail an assignment, I tell you not only that you can retake it and that in my course you're allowed to consult lessons while doing assignments, but also that if there are parts of a lesson you don't understand, feel free to send me a message asking me questions. A few of you have asked me questions, but only a small fraction of those who fail assignments. If you take me up on my offer, you will have no trouble passing the course.
As much as I hate to bring up this subject, too many students have submitted plagiarized essays. Some of them have been in foreign languages. Apparently some students think that they can plagiarize a part of a web site and get away with it if it's in a foreign language. There are plagiarism detectors that will catch a plagiarized essay no matter what language it's written in. A plagiarized essay will be given a grade of 0% and cannot be retaken. Any essay written in a student's own words results in a better outcome than that, no matter how bad it is, because even if it is totally worthless and gets a grade of 0%, it can still be retaken.
Note: Please write to me in English. If necessary, use the web site "Google Translate" to translate what you write from your native language into English. Your essays and short answers should also be written in English.
My name is Professor Robert Plumb. If you want to discuss the course material or anything else with me, feel free to send me an owl. You can also ask questions of any one of my PAs. There are links to each of my PAs for each year of Astronomy on the screen for that course and year.
The new Astronomy 101 lessons have all been published. You are allowed to consult the lessons while doing assignments, but for some of the questions, the lessons don't contain the answers, only the information that will enable you to deduce the answers, which will require logical thinking. If you have completed the current Year One course, you are not required to do the new one, but it would be advisable to do so, because the material in it will be tested on your O.W.L. exam.
I was born in Toronto, Canada, on June 27, 1968. Both my parents are Muggles and I have no siblings. At the age of 8 I became fascinated with astronomy and I devoured all the astronomy books in the Toronto Public Library. In 1979, at the age of 11, I was invited to study at Hogwarts. I declined the invitation because Voldemort was running things in Britain. Instead I studied in Muggle schools, graduating from secondary school with top grades in mathematics and physics, grades ranging from good (in chemistry) to mediocre (in history) and the second-lowest grade in my class in physical training; the only boy who got a lower grade was being punished for bad behaviour. I then studied mathematics, physics, and astronomy at the University of Toronto and earned my PhD in astronomy in 1992.
Then, with Voldemort having been (temporarily) defeated, I enrolled in Hogwarts as a mature student and was sorted into Ravenclaw. You won’t have heard of my having studied at Hogwarts because I kept a low profile. There I learned for the first time about magical astronomy, which fascinates me as much as Muggle astronomy ever did. I eventually graduated with some Os including Astronomy, some Es and one gentleman’s A, in DADA, because I was too unathletic to duel effectively.
There being no opening in Hogwarts for an Astronomy Professor, I returned to Toronto, where I eked out a living giving private lessons in mathematics, physics, and astronomy until a position opened up at the Richmond Hill Observatory just north of Toronto. There I met a woman with whom I instantly fell in love - a Muggle. We got married soon thereafter and we now have two sons, both Squibs, and both already grown men.
A position as Astronomy Professor in Hogwarts opened up in 2018. I applied for it and was accepted in early 2019; so now I will resume my role as an educator, this time teaching magical as well as Muggle astronomy.
