    Pretty eye-opening how fast that is.

    And it's still too slow for interstellar travel...

    There's this really cool scene in The Expanse where one of the protagonists on Earth has a video chat with her husband on the Moon and everything has a three second delay due zo travel time which did a really good job at examplifying this.

    It's funny when you realize that - if we travel with speed of light, we will freely explore our solar system and only the closest stars.

    As a kid I often used to point my flashlight at the Moon and flash it on/off in hopes of getting a reply.

    I imagine that in the future, taking a warp drive ship from Earth to Luna Base will be like flying from Boston to JFK. Rich business people will do it because they can and then tell everyone it's more convenient, even though the plasma ionic drive Greyhound shuttle is only 35 bucks and gets you there in the same amount of time when you take security and prep time into account.

    Mind sharing where it was taken? Within two hundred miles would be plenty close enough, also facing which compass direction?

  • smurf123_123

    I shot this on August 11th 2018 in North Frontenac Ontario, Canada.

    Single 6 second exposure F2.8 ISO 6400 18mm Zeiss Lense with my Sony A7S.

    Minimal post processing, North Frontenac is a dark sky preserve and there was minimal atmospheric distortion that night. The mosquitos were a little intense but it was worth it.

Lovejoy Comet Flies Over Southern Hemisphere

    This video was taken by the crew of Expedition 30 on board the International Space Station. The sequence of shots was taken December 21, 2011 from 17:35:50 to 17:43:02 GMT, on a pass from eastern Australia southeast to New Zealand. This brief video features the Lovejoy Comet, which passed by the sun around December 16, and was seen over the Southern Hemisphere near the South Pacific countries.

This is a 44 shot, 420MP image I took recently of the summer Milky Way at Island Point in Western Australia

    Nikon d5500 - 44 x 30 seconds - ISO 4000 - f/2.8 - 50mm
    iOptron Skytracker + Hoya Red Intensifier Filter

    It's the off season for photographing the core of the Milky Way but that doesn't mean we still can't find some cools stuff in the night sky. This is a panorama of the Magellanic Clouds and Eta Carinae rising vertically over Island Point in Western Australia. I had to wait til after midnight to get the right alignment for this shot which is comprised of 44 individual photos taken in a lawnmower grid pattern using an iOptron star tracking mount. The Hoya Red Intensifier filter is a didymium filter used mainly to minimise light pollution but also to highlight H-Alpha nebulae such as Eta Carinae, which you can see here as the pinkish blob in the top centre, and Lamda Centauri which is the smaller pink blob just below that. The original image came out at a little over 420 megapixels.
    Unfortunately for those of you in the Northern Hemisphere you can only get this view in Southern Hemisphere skies as the Magellanic Clouds aren't visible much north of the equator. But you guys get Andromeda so I think that's a fair trade off!

    M45, a massively bright star cluster, visible within even heavy light pollution due to the low magnitude of the primary stars. While the nebulosity is not particularly visible without imaging, with the assistance of long exposures (10 min), and stacking, we are able to extract the beautiful reflection nebulae that surrounds this object.

    Fun Fact: The Subaru emblem is based off this object

    Sad, what the thargoids ate doing to that area of space.

    M45, a massively bright star cluster, visible within even heavy light pollution due to the low magnitude of the primary stars. While the nebulosity is not particularly visible without imaging, with the assistance of long exposures (10 min), and stacking, we are able to extract the beautiful reflection nebulae that surrounds this object.

    Fun Fact: The Subaru emblem is based off this object

    Is that some type of atmospheric distortion or what happened to the moon?
