    Default The Complete Galactic Plane

    The Complete Galactic Plane (ARTICLE LINK)

    Explanation:
    Is it possible to capture the entire plane of our galaxy in a single image? Yes, but not in one exposure -- and it took some planning to do it in two. The top part of the featured image is the night sky above Lebanon,north of the equator, taken in 2017 June. The image was taken at a time when the central band of the Milky Way Galaxy passed directly overhead. The bottom half was similarly captured six months later in latitude-opposite Chile,south of Earth's equator. Each image therefore captured the night sky in exactly the opposite direction of the other, when fully half the Galactic plane was visible. The southern half was then inverted -- car and all -- and digitally appended to the top half to show the entire central band of our Galaxy,as a circle, in a single image. Many stars and nebulas are visible, with the Large Magellanic Cloud being particularly notable inside the lower half of the complete galactic circle.

    Hope the voyage is a long one.
    May there be many a summer morning when,
    with what pleasure, what joy,
    you come into harbors seen for the first time...

    Nice, pity its the wrong shape for a screen saver.
    It really is quite difficult to build an ugly wooden boat.

    It's amazing how few people have actually seen the Milky Way.

    That's the best thing about a storm that knocks power out for a few days.....the night sky becomes visible.....a few thousand stars, a baker's dozen nebulae, a galaxy or two, meteors, if you're lucky, a comet wandering by....all you need is the good old Mk I Eyeball. Even more fun is had with binocs and a good reference, like Nightwatch (LINK).

    I live rather far out in the countryside, but there is still enough light from neighbors to make it impossible to see the Milky Way.

    Once or twice each year my office loses power. My (was 5, but is now) 3 computers go silent. It was almost unnerving. For a time I don't know what to do. Light and noise is such a part of our everyday life that we forget what it's like to have dark quiet to think.

    When I sailed on the Chesapeake Bay at night I could see it.

    Are you saying that it is good to be in the dark? This is good news for Ol' Blooie, Da Noise, etc.

    Lovely sky pics, BTW...
    Hope for the best, but plan for the worst.

    From the top of our hill we get a really good appreciation, no street lighting in our country location. But Melbourne is 80K away, and spread out around the bay. Since I was a child on grandparents farm, out on the Nullabor was the best view I've ever had. About 500K from anything but a local domestic light source. Grandfather had a 4" telescope he'd made himself while in the Royal Engineers.

    Just off the Cumberland Plateau (& on it, esp in the BSF), I see the Milky Way on a regular basis - hell, I go out specifically to gaze starward. Still, northern Maine winter on the flightline in the 70's, or a mountaintop in the desert - are hard to beat.

    And yes, Michael.. I like being in the dark. (-;

    Durnik, where I rest my head is about eight miles outside of a small town (Yarmouth, to the south) and surrounded on all other sides by lots and lots of unpopulated woods. We have a grand view of the Milky Way every clear night. Not far away is Kejimkujik National Park (locals call it 'Keji') which was recently designated an official Dark Sky Preserve by the Royal Astronomical Society of Canada, and nearer (about six miles from me) is the Deep Sky Eye Observatory in Quinan. The photo below is of the Deep Sky location:



    Maureen & I often sit out on the deck on warm evenings and stargaze. We are also under the primary flyway for planes from the US eastern seaboard heading for Europe, so there is lots of moving stuff in the sky as well.
    Hope for the best, but plan for the worst.

    official Dark Sky Preserve
    Damn, be still my beating heart..

    Phew.

    When I hike out to say Twin Arches in the Big South Fork, on a clear, cold winters night.. waaaay off, I can see two blinking red tower lights and in another direction, two faint white lights.. and with no moisture.. even Jamestown, the nearest small 'city', is unseen. Best part? I've never run into other humans at night.. Ahhhhh, peace, beauty, quiet. Caught a lunar eclipse there a year or so back.. what a sight!

    Yep, thinking I could live with your neighborhood..

    Good point! On big water or big desserts are both excellent places to see the Milky Way!
