    Galaxies

    We, as I am sure you know, live in the Milky way galaxy.
    That means our sun is only one of the countless trillions of stars that go to make up our galaxy, all the stars you can see are part of our own galaxy, all the nebulae you can see, are again gas clouds floating in our galaxy , and more specifically our part of the galaxy.

    Now imagine

    When you are in a plane you are travelling at about 5-600mph which is about as fast as any of us get.

    Imagine travelling in a plane doing 10,000 mph a million, ten million

    Mind blown yet ?


    Imagine flying at 187,000 miles a second - :eek: that is the speed of light. Travelling at this mind blowing speed it would still take you 100,000 years to fly from 1 side of our galaxy to the other ( without stopping for a wee).

    This is 1 x 2 minute shot taken as I was packing up last night

    [​IMG]

    2 pretty obvious galaxies but if you look harder at some of the feinter smudges

    [​IMG]

    There are 8 other galaxies here in one tiny field of view

    And that was just a 2 minute sub - a longer exposure would have shown many more.


    Blows my mind every time

    Incomprehensible.

    Stunning.

    I feel like if I were to ever start gazing I'd not be able to pull myself away...

    I always thought it was pretty arrogant of people to think that we were the only thing in this ginormous universe. If they watch the news, it's no surprise they don't make themselves known to us :tongue:

    I just can't begin to wrap my mind around the distances involved here. :thud:

    For anyone who's interested and is a Windows user (or, like me, a Mac user with Bootcamp), I found Microsoft's World Wide Telescope to be a marvelous tool to help with the experience.

    Also, if you've installed the World Wide Telescope, there's even a tour by our old pal Wall-E available. :happydance:

    Tom (whose mind was was successfully blown with talk of such distances)

    Oh, can't see the image here Chris, blocked but will check it out upon arriving at home this evening. I am sure it is fantastic, you have a knack for astrophotography.

    There is a really nice alignment of Jupiter and Venus in the Southern sky just after sunset. Venus is so bright! Jupiter is the bright light a bit higher in the sky.

    Now what used to freak my students out is to know that we are all from somewhere distant. Much of the atoms and compounds making up our bodies could not have come from the normal fusion of a star like our sun, but must have been made from a super nova. Our sun can only "construct" atoms with a max of 26 protons. Any thing bigger, like gold for example, had to be produced by a massive explosion some great distance from Earth, had to be collected by the gravity and become part of our Earth.

    Dan I love the thought we are all made of stardust - I love the way thi shobby turns my brain to mush on a daily basis.

    Once when looking at a solar flare it all became very 'real' and I realised fully for the first time how fake 'night' and 'day' are and how it is just us spinning around this ordinary star and the light pollution from that star hiding the universe.

    I felt really quite giddy and felt the need to lie down

    magic :D

    You are very kind about the photos but this is far from a proper shot was just one I took whilst doing my darks for my nebula shots

    Chris, you have now whetted my appetite to try to capture some "sky" shots using my camera.
    I have a Nikon D70 which should be up to the job but how do you enable the camera to "travel" with the subject in view of the long exposures necessary?
    [Apologies if you have been asked, [or if you have explained this] in an earlier thread.]

    Ah Terry, thats how it started for me :lol:

    I'd start by doing some undriven sky shots to see if you really are interested before opening your wallet as soon as you start it becomes potentially a very expensive hobby.

    I'll post more on another thread :D

    When can Steven come and look through your telescope?
