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
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?
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.
Heh... it was flour. I was wondering why nobody asked! :)
I relooked yesterday .... still haven't seen it LOL
Two recent clips about the ISS:
The International Space Station Has Made Its 100,000th Orbit!
International Space Station Marks 100,000 Orbits of Earth
and on PhysOrg: http://phys.org/news/2016-05-international-space-station-100000th-orbit.html
Awesome, thought I'd share a few screenshots.
A new clip from Babak Tafreshi with music by Ali Raini:
That is "MagicalMedia" I loved it. Thanks for the post!
Not sure how to post this other than a URL but let me know what you think after watching the whole clip.
An ambitious project indeed! And a very cool and inspiring one!
Hercules is now coming into view- got this one last night- the whole field of view and a 100% crop (800/5.6, ISO 1250):
My technique is finally good enough that I needed to program periodic error correction (PEC) on the motors; my first attempt wasn't great but I could still nearly double the exposure time (5 s to 8 s). Presumably, as I keep refining the PEC, the performance will continue to improve.
Up to 28 minutes total exposure time- image quality and colorimetrics significantly improved:
You know, when I came across this image all I could think is, this belongs on the OBU thread. So here are the Spanish peaks in Colorado, along with credit where credit is due.
For the next few days, (from left to right) saturn, mars, and jupiter are all visible at night:
And a little zoomed in (the red spot is visible):
Tonight, 9pm- midnight, Europa is transiting Jupiter and the shadow may be visible (midnight - 3am, EST)... fingers crossed for good viewing conditions!
the image in the previous post was better, colour wise ... you have gone back to a very green hue in this one The star sharpness in this one is much better
You guys sure make me want a nice "Scope" I'm feeling motivated but I have a lot to learn.
I feel exactly the same . I've been thinking about a scope for years now, but I've had other things to do, and if I get a scope I want to put it to good use. I have been very tempted by this entry level scope, which have got some pretty good reviews (e.g. it won the comparison with other scopes here: http://telescopes.toptenreviews.com/telescopes-for-beginners-review/celestron-cosmos-review.html [Broken])...
And a clip here:
I can speak from experience- people here are excellent resources for learning this stuff. Go for it!
I'm going to start getting the ducks in a row, it will take time but I have been accused of having too much patience.
I also find these sites inspirational.
Another investment opportunity missed.
http://www.celestron.com/browse-shop/astronomy/telescopes/cosmos-90gt-wifi-telescope $400.00 US
Amazon $670.47 US
That would be a nice starter.
