  1. Conservation of angular momentum if what causes clouds to flatten out into a disk. The interstellar dust and gas cloud that the Sun and Solar System formed from, along with other stars. started to rotate when the bow-shock wave of matter and energy from one or more relatively nearby supernovae encountered the interstellar dust and gas cloud. The other stars that formed at the same time that the Sun did dispersed long ago. If you want to look at a relatively young open star cluster that still has traces of nebulosity around it, look at the Pleiades with binoculars after sunset tonight. If you have REALLY good naked eye vision, you might even be able to see the tiny Little Dipper shape of the brightest of the Pleiades. There's another open cluster called the Hyades relatively close by that bright orange giant star Aldebaran is in front of. Aldebaran is the "eye" of the bull constellation of Taurus Clouds interstellar gas and dust clouds flatten out because of conservation of momentum mass and energy. This does NOT completely explain some planetary systems. When astronomers started discovering planetary systems with planets that revolve around their primary star in the opposite direction to the star's rotation, scientists originally said "That can't happen, because it violates the conservation of mass/matter, energy, and momentum". Some OTHER forces acted on planets with orbits like that AFTER the planets were formed. Scientists gave a name to the effect using the last names of two people that begin with "M" and "R."
  2. Cheers Bob for the help, will give it a go tomorrow, its a bit late to try now, just finished work so brain power is down lol Ronnie
  3. lol, though I dont know what you are talking about above, I am interested in meteors so I am going to keep popping on over here and read your finds, what equipment are you using and are you scanning these meteors, plus is there a program I can access to maybe learn a little more Ronnie
  4. Well guys this is over my head, been reading some of your posts and though find it somewhat fascinating I have no idea what going on lol, I thought I would pop on over to this topic to see what discussions you are all having, so hope you do not mind, I cannot help in any of your queries, I give you all a thumbs up before I leave you all. Ronnie
  5. I don't suppose you got a picture, would have loved to see it
  6. For many years I have had formal discussion among a select few on the topic of multi universes, we are not altogether sure of what actually lies out there. However I do believe somewhere hidden is that certain key which will unlock this mystery, many have spoken of black holes, how they hold that something magical within the singularity, getting to find that out can be somewhat of a dilemma, though saying that in years to come someone might find a way of getting around the obstacle of gravity, but that's another story. So yes I definitely believe we live in a multi universe. Nice topic for a discussion Ronnie
  7. Hi guys I just wanted to pick your brains sort of speak, it would be most appreciated if you could help. here are the questions. a) The luminosity of the Sun is 4*10^33 erg/s, and its radius is 7*10^10 cm. You are tasked with building a solar power plant in the Arizona desert, using solar panels with 10% efficiency. How large an area (km^2) must your solar panels cover to match the power output of a large nuclear powerplant (about a GigaWatt)? Please enter your answer in units of km^2 The Keck telescope on Mauna Kea has an angular resolution on Earth of half an arcsecond. How far away (in meters) could you read ("resolve the letters of") a book with 3 mm square type, using the Keck telescope on Earth? c) In space, the angular resolution of the Keck telescope is govererned by the diffraction limit. How far away could you read the same book, using the Keck telescope in space? Please express your answers in units of meters. These questions are from a free astronomy topic from coursera, anyone can join for free, its fun but some of the questions have placed me in a stump, I cannot move forward until I complete these three. Ronnie
  8. We should use this link for all who are registered on the course to communicate with one another if we need help and so on, just a thought
  9. Thanks for the link, just registered on the course, I have another link for you all to look at, named coursers, they have loads of courses on astronomy, check it out and see what you think. Introduction to Astronomy is a great course so is Galaxy and Cosmology, there are many others also.
  10. Excellent I might take your path after this one, I too have a great interest in astronomy, especially the cosmology side of things, I have been personally studying the black hole for a number of years and it's soooo fascinating
  11. Good look on achieving your goal on a full degree, are you hoping to explore your knowledge or are you looking to change yr career, being 48 I think for me it's more of knowledge for me, expanding the brain cells, always been fascinating in space, however the only space I have exploded is the space between my ears lol. On a serious note I would like to teach a small group, more of a club, where we can all sit and exchange our ideas and so on, so doing this course will be a great start, do you know coursera do loads of free astronomy courses, I have completed About three all together, you also get a certificate at the end of the course, but, they are not credited courses, but great fun, check it out Ronnie
  12. Hi Avo thanks for all that, I am looking at enrolling in 10th October is the closing time for the course. So Jay T if you want to start the course we me you have until October to enroll, unless you are doing it next year . Avo I would very much appreciate those text books if you are sure you do not need them, I can then have a good read before starting. How do I cover the postage.
  13. Thanks guys, sorry about the mistake, its S10 which I will be taking and S282 is in fact one of the modules, I have been interested in astronomy from being a young boy, now i am 47 I just want to broaden my knowledge more, I have taken a number of free on line courses and I think I am ready to push even further my doing an OU course. thanks again Ronnie
  14. Hi all , I am looking at participating in taking a OU course S282, I was hoping those who have taken up this course can help me in finding the right books to read and which would be the best modules and so on. Thanks guys
  15. according to the quantum mechanical uncertainty principle, rotating black holes should create and emit particles.Hawking radiation reduces the mass and the energy of the black hole and is therefore also known as black hole evaporation.
