Astronomy Q&A Game

    [SOLVED] Astronomy Q&A Game

    Hi guys! Most of you know how this works but for the newcomers:

    The rules are this: someone will ask a question and if the question is not answered correctly within 3 days then a new question will be posted. If an answer to a question is posted and the person that posted the question does not respond to the answer within 2 to 3 days, then the first person to have answered the question will then be able to post their own question. HAVE FUN AND LEARN!

    I will start:

    Question: What is the brightest star in the Northern Sky? (excluding the sun)

    I'm making an educated guess here:

    Alpha Canis Majoris (Sirius)?

    Techincally, I think Deneb is the "brightest" but only in absolute magnitude. It's so far away that it really doesn't make much of a difference since its apparent magnitude is not as bright as Sirius.

    Hey it's only a guess.

    haha *hurt look* us? Phobos why ever would you say that? hehe

    Yes sting you are correct, your go.

    My go? My turn to ask a question (I never participated in the original thread so I have no idea how this works)?

    Okay, my question: What is the name of the large multiringed basin located on Mercury at a longitude of 180 degrees?
  7. Mar 9, 2003 #6
    I believe that it is the Caloris Basin. Am I correct?
  8. Mar 9, 2003 #7
    $#%^! I sure pick easy questions don't I?

    Yes, you got it right. I guess, it's "your go"
  9. Mar 9, 2003 #8
    I knew that from when I studied Astronomy for Science Olympiad (By the way guys I got a gold medal in Astronomy for the Competition )

    Ok. True Or False

    Do we havea supermassive black hole at the center of our galaxy?
  10. Mar 9, 2003 #9
    Shoot, that was quick...

    Uhhh truefalse...

    Actually, I don't know if it was ever "proven" but I'm going with "true"
  11. Mar 9, 2003 #10
    Correct, it is true. On Discover, they lookd at something like 37 galaxies and in each one, they found a supermassive black hole. Then, they looked at our galaxy and guesss what they found... Oh wait, sting already said it.

    Okay, I guess it's my turn:

    What is the name given to the energy generation in which a stellar object initiates helium burning by the triple-alpha process?
  13. Mar 9, 2003 #12
    OK I don't think I know this one but I'm gonna go out on a limb and say the Nuclear Fusion that a star relies on to live.... but I am not sure if that's right.

    for how many years does pluto enter into neptune's orbit, and how many years does it take pluto to make one revolution around the sun?

    no cheating...
  15. Mar 9, 2003 #14
    Kerrie I'm gonna answer your question but first The way I put it in the rules was that one question had to be answered before the next was asked that way you dont have a bunch of questions going on at once :smile:

    Answer: Pluto takes 247 years that is the first answer. The second is... well I am not sure but I think it is around 100 years although that is basicaly just a guess.
  16. Mar 17, 2003 #15
    Generally, yes, but I was thinking more of a specific name but I'll give you a clue (two words)
  17. Mar 17, 2003 #16
    helium fusion...?

    What is the 'helium flash'?
  19. Mar 17, 2003 #18
    Well if I was being tricky I would say exactly 1. Plutonian year that is :wink:

  20. Mar 17, 2003 #19
    Darn, I do believe damgo got it.
  21. Mar 17, 2003 #20
    It takes pluto 250 earth years to make one revolution around the sun.
