I can't get enough of this 'song'.

SYMPHONY OF SCIENCE - WAVES OF LIGHT
Symphony of Science returns! A musical celebration of light and how it tells the story of our universe. Featuring Brian Cox.

I would kill myself now, as the image of Pluto is, as people say; "I can die now".
But there's more to come, so, not today.

I just recently joined this forum and this thread only would have made the act worthwhile. I am going to mark it as a favorite so that i don't lose it because i can't watch all those great videos in a single setting. thanks everyone for sharing! p.s. I am an action photographer but i managed to get this picture of venus and the moon right before the transit that occurred a few years back. I had forgotten that venus goes through cycles in a similar fashion as our moon.
sincerely,
k. doc holiday

Welcome to PF :)

nice pic of the 2 ... but you really mean occultation ... neither the Moon nor Venus transit each other

An occultation is when a visually small object goes behind a larger body eg. the moon occultates planets, stars, nebula etc
A transit is the opposite, when a visually small object goes across the face of a larger object ...
we see transits eg. transits of Mercury and Venus across the face of the Sun. The moons of Jupiter across the face of Jupitercheers

Thanks Dave, that is exactly what i meant. I must have been thinking about the transit of Venus across the sun in 2004, which is, of course, a very rare event. I love constructive criticism. please keep it coming!

all cool

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
Always looking forward to seeing more people having a go at the nite sky

 

[Ironmanlet]

I love you all so much.

Amazing video, really understand how galaxy is great

 

[OmCheeto]

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:

Awesome video even if you don't have 4K soft/hardware. (full screen recommended)

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

Magical is a great description, . 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. ( I love space and stuff )

 

[DennisN]

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 Dave

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."

Explain what you've just seen, in 100 words years, or less.

-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

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.

 

[Andy Resnick]

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 betterD
