    The Sun makes a full rotation once every 25-35 days.

    On the Apollo 11 mission Michael Collins continued to orbit the moon in the command module while Armstrong and Aldrin walked on the moon. For 48 minutes he was on the side of the moon facing away from earth with no radio contact to either Earth or the astronauts.

    Btw this is [to scale] how far away the moon is from Earth linearly.

    that do not make right in my mind. if moon so far why it so big when i look at night?

    Because it's relatively close compared to the other stars. The sun seems closer, but that's because it's so big.

    cee134, correct me if I'm wrong.

    The Ebbinghaus illusion. The lower central circle surrounded by small circles might represent the horizon moon accompanied by objects of smaller visual extent, while the upper central circle represents the zenith moon surrounded by expanses of sky of larger visual extent. Although both central circles are actually the same size, the lower one looks larger to many people.

    It seems close because we can see it so well. Sometimes it's closer depending where it is in it's orbit but on average it's 240,000 miles (~380,000+ km). We measure the distance to the moon often using reflectors and timing how long it takes for the light to come back.

    The best thing about space, are space kittens!

    Looks to me the best thing is space PIZZA!

    Do NOT focus on the pizza!! I gained weight just looking at it LOL

    It's ok! Less gravity = weigh less

    But less gravity does not equal less mass or volume

    Sorry! Lol.

    Which is why I said weight

    :D That's just psuedo-science

    Real funny. I noted you made a big deal about my opinion and quotes and then said basically nothing when I responded. But then you bring it up again with playdoh pants.

    I'm guessing because we don't want to turn this thread into a religious debate.

    Had nothing to do with religion. It had to do with the scientific method being pushed to the wayside, and speaking about hypotheticals to the general public as facts when they know the general public may not be able to differentiate between the two, as in the case of Cosmos.

    Moreover, it was he who made a big deal of it, not me.

    And there's the thing, I'm a telescope hobbyist...am I the only one on the planet who has not actually observed the Milky Way Galaxy in the way that some pictures capture it? Even with dark skies. I'm doing it wrong but would love to see it. y

    well yeah...cause I'm a *kitten*

    Also, we differ in opinion and that is fine. I respect your views about what you said, and while I disagree, I at least understand your perspective.

    Cool.

    Hi...no i know the colors are filtered, although I am enthralled by the colors put on planetary gases when I look at Nebula etc....but just the cluster of the Milky Way....I can never find it...another rant, I've only seen Saturn once through a small telescope and it was impressive. I've been looking ever since. Even though I may know where it is in the sky I spend more time looking and give up. Space rant. Thanks for listening.

    From here

    http://voyager.jpl.nasa.gov/imagesvideo/imagesbyvoyager.html

    You can see images taken by Voyager 1, the farthest man-made object from Earth

    Outstanding...thanks for posting. Love this stuff.

    Space is truly unfathomable. I love watching cosmos with my girl Mary. Blows my mind every time!

    The television show Cosmos is pseudoscience in large degree.

    That's cool. You must be significantly more intelligent than Neil Degrasse Tyson.

    Please, please teach me everything you know. :|


    Neil Degrasse Tyson thinks we are "most likely" living inside a computer simulation.

    Because reality does not match the picture they paint for us?

    My favorite video on space, measurement, and perspective. It's an oldie but goodie:

    And would you like to share with the class why it's "25-35"? :smiley:

    It's the sun. It does what it wants.

    But also:

    The Sun has a north and south pole, just as the Earth does, and rotates on its axis. However, unlike Earth which rotates at all latitudes every 24 hours, the Sun rotates every 25 days at the equator and takes progressively longer to rotate at higher latitudes, up to 35 days at the poles. This is known as differential rotation. Because the Sun is not solid, but is instead a giant ball of gas and plasma, different parts of the Sun spin at different rates.
