How Far Away Is It - 14 - Local Superclusters (4K)

Wiki page

In this segment of our “How far away is it” video book, we cover the local superclusters closest to our supercluster, Virgo.

First we discuss the overall structure of the nearest 20 superclusters and illustrate the galactic structures of galaxy filaments, walls and voids including: the Sculuptor void; the Perseus-Pegasus filament; the Fornax, Centaurus, and Sculptor walls as well as the Great Wall or Coma wall. Then we take a look at several of these superclusters and some of the galaxies in each one we examine.

We start with the Hydra Supercluster with the Hydra Galaxy Cluster at its center. We examine NGC 2314, a rare double aligned pair of galaxies. We then move to the Centaurus Supercluster with the Centaurus Galaxy Cluster at its center. We then take a look at some of the galaxies in this supercluster including NGC 4603, NGC 4622, the unusual NGC 4650A, and NGC 4696. We then move on to the Perseus-Pisces Supercluster and the Perseus galaxy cluster within it and the remarkable galaxy NGC 1275 within it. Then we cover the Coma Supercluster with the Coma galaxy cluster at its center. We then take a look at the beautiful and wispy galaxy NGC 4921 along with NGC 4911. Then we review the distances to some of the other local superclusters including Hercules, Leo, Shapely, Horologium, and the 1 billion light years distant Corona-Borealis Supercluster.

Next we cover a new way to identify superclusters with a focus on our own called Laniakea. We then take a look at additional galaxies within a billion light years of us including: ESO 510 – G13; NGC 6782; ESO 243-49 HLX-1 with a supermassive back hole in its disk; Stephan’s Quintet; interacting galaxies NGC 1409 and NGC 1410; interacting galaxies ARP 127 and NGC 5679; galaxy cluster Abell S0740; ESO 325-G004 with its unique gravitational lens arcs called Einstein’s rings; and finish with the very interesting Hoag’s Object.

Finally, we cover the unusual peculiar motion superimposed on the normal Hubble flow that all the galaxies within a billion light years have. It appears that they are all moving towards a Great Attractor in the Norma or Shapley Supercluster. We end with a map of all the local superclusters where we highlight the ones we’ve seen and list the number of objects that exist out to this distance.}

How in the hell does this man only have 112K subscribers. Any person in the world can get a free basic understanding of what science knows about the universe by watching these video books. ITS FREE! Take some time, watch them a few times, and his voice is perfect for narration. He should be reading audio books for a living. He should have 100 million subscribers.

The music always works perfectly in these videos.

Mr Butler, we're extremely fortunate to have you.

[MsYuki]

I am obsessed with and adore your beautiful and informative videos. Thank you.
Also, and this is high praise from one who suffers from insomnia, your voice and music choices are so relaxing that you help me nod off to sleep. (I go back and rewatch the next day.)

I’ve learnt about space mostly from this series more than any other sources.

[book]

The detail on these really deep space images is unbelievable.
Just fantastic!
And here we are, almost casual about it.
Thanks, Mr. Butler. :)

Another superb learning experience from David Butler. What a great teacher!

[mablizza]

The Laniakea discovery and images were absolutely amazing! Thx for sharing!

[MtnCommando]

Outstanding, ethereal, beautiful video! Really does a great job of conveying the scale and sheer grandeur of the universe (or at least 7% of it :) And your narration is very soothing and fits perfectly! Thank you for this lovely piece of work

[messier]

All the work hubble has done over the many years is almost unimaginable

[falten]

Thx david.

I always recommend this channel whenever I can.

I get thorough enjoyment of watching the show and learning about galaxy structure. This is the world class.

[abdulkaderalsalhi]

The sky is beautiful without zooming in, it becomes a wonderful scene and a frightening place with telescopes zooming in! Thank you Dr Butler for these (I3). I really enjoyed watching this video.

[merveilmeok]

Thanks my Uncle from the Universe. I learn every day. Cheers.

[YogiMcCaw]

This makes me feel like I am sitting in a planetarium, especially the way the visuals zoom in and out and the classical music BG. Plus it's a nice meditation just trying to imagine the distances and numbers of stars and galaxies. Very enjoyable and educational at the same time!

David, you are so good at explaining the complex workings of the solar I'm learning more from you, than most other talented 'YouTube' creators, on these same topics.
Thank you for your work..
Greg

[olystreet]

One of the best, informative and inspirational channels on YouTube. Thank you David! Please get a job on the sky at night (UK)

[elvis-slippers]

Magnificent views, brilliant description and an outlook into a world that is beyond anyone's imagination. Subhan Allah

[Pakornin]

You are very good at teaching astronomy. Thank you for making these videos.

[mcpamy]

Thank you, Mr. Butler, I have enjoyed and apprecaited so much for all your videos... not only are they very educational, but also so well made and well presented. Thank you so very much, you are truly awesome! (I recently entered my retirement, and can't stop watching your videos which I have learned so much about ... thank you)
