    all cool :smile:

    for future images you post, just create a thread in the main astronomy section
    periodically you will see astro pic posts by Andy Resnick, Russ Watters and myself being the 3 main contributors
    and a couple of others on occasions :smile:
    Always looking forward to seeing more people having a go at the nite sky

    I just love watching the sun, revolve, and via new techno-eyes, evolve.


    I like that they replayed the whole thing, and had someone explain things to me in slo-mo. That actually made it much better.

    A pretty cool idea how to show size comparisons...

    Three clips on gravitational waves, LIGO and the recent discovery:

    Very nice videos, @1oldman2! The third video (Aurora Borealis) was magical! :smile:

    Magical is a great description, :thumbup:. I found myself caught up in any of the SDO video also, puts Hollywoods "Special effects" too shame. I was going to post some of that stuff to the new video thread but not sure how to pull it off, however this looked like the perfect thread for it. :smile: ( I love space and stuff )

    We have got quite a few clips from the ISS in this thread, so I thought I'd post a tour of the International Space Station itself (1080p):

    Without the existence of Fourth dimension aka time the universe is useless to look at.

    The constellation Virgo is passing by and I'm in the process of assembling a panoramic image of the dense cluster of galaxies present. I have another month or so to acquire images before it's time to move on to Hercules, but in the meantime here's a small menagerie of the more visible non-elliptical (except one) galaxies present in this region:

    Integration times vary, ranging between about 17 and 50 minutes. 400/2.8, ISO 1000.

    nice one Andy
    The Virgo Cluster is a cool place to test out a scope and eyesight seeing how many faint fuzzies can be picked out :smile:

    This was a great shot! It made me a little curious, so I went through some of your photobucket.

    Now, I have to ask you a weird question... What was that off-white, powdery substance cut out into four lines with the Santa Claus figure behind it? Fuel for your many passions and talents? :smile:

    A newer one I found:


    But, this next is my very most favorite at the moment. The amount of work and computational power that went into this 11 sec(or so I can find) simulation is incredible. I do enjoy other videos and many are quite creative and artistic, but I prefer ones that are published by researchers or where I can at least find some credibility for the video. They also found that the reionization era ended later than we predicted earlier from observations and need to make adjustments.
    "Such a multi-faceted simulation needed not only a powerful supercomputer, but also one that had plenty of GPUs so the team could offload its radiation and ionization calculations. Thankfully, the Oak Ridge Leadership Computing Facility’s (OLCF’s) Cray XK7 Titan supercomputer fit the description. The OLCF, a DOE Office of Science User Facility located at ORNL, built Titan with a GPU for every one of its 18,688 compute nodes. The Shapiro team needed 8,192 GPUs to run its simulations."

    -Entropy increases in the atmosphere the closer that it gets to the surface of the earth.

    NASA has a model for the ocean currents in one of those videos posted- incredible to watch it move relative to the land masses. You know though, it sure would be nice to see what the core of the earth really looks like. Then all 3(or more layers) could be placed into one model zooming from the core out to the upper atmosphere and back again.
