How Far Away Is It - 11 - Andromeda and the Local Group (4K)

Wiki page

In this segment of our “How far away is it” video book, we cover the Andromeda galaxy along with our local group of galaxies, including some of the dwarf galaxies orbiting the Milky Way.

We begin with Edwin Hubble’s discovery of a Cepheid variable star in what was thought to be a Milky Way nebula. The star was V1 and it changed the history of astronomy. We also take a deep dive into the galaxy’s disk, and point out what was going on here on our planet when the light we see left Andromeda on its journey into our telescopes. We finish with a look at Andromeda’s collision course with our Milky Way.

Next, we identify the local group of galaxies including: Triangulum with its great star birth H II region NGC 604; irregular galaxy NGC 6822 with its unique Hubble V H II region; the recently discovered galaxy IC 10; nearly edge on galaxy 3109; and Sextans A.

We then cover 5 of the dwarf galaxies orbiting the Milky Way including Sagittarius Dwarf, Sculptor Dwarf and Fornax Dwarf along with the Large Magellanic Cloud and the Small Magellanic Cloud. Then we examine some of the amazing nebula within these two dwarf galaxies including: Supernova Remnant N 63A, SN 0509-67.5, the Tarantula Nebula, 30 Doradus, Hodge 301, the Double Bubble, LH 95, NGC 2074, NGC 602, NGC 346 and others. We conclude with a review of the galaxies we covered marked on a map of the Local Group.

I Don't see how it's humanly possible to watch this program & take in the information without feeling incomparably tiny. The telescopes that are world has been launching over the last 15 or 20 years are simply and truly amazing and it just gets better every day. I was watching the show and marveling at the fact that they could zoom in and the resolution was mapping time as we zoomed in unbelievable remarkable astounding I don't know any other adjectives that could really describe this thank you

Not all heroes wear capes. Some are named David Butler and post incredibly informative videos that have beautiful music narrated with his delightfully relaxing voice. Unless of course Mr. Butler wears a cape, in which case all heroes wear capes.

I can't believe I am just now learning about this channel. My kids watch your videos with me before bed. Seeing them listen to every word and ask me questions, their little minds in awe and wonder at the universe while I hold them in my arms gives me a peace and happiness that's hard to describe. Thank you!

How cool it is that Mr Butler posts some of the most interesting and informative videos on the internet — and then keeps them up to date and in 4K? Thank you Mr Butler for your wonderful work.

[rogerulloa]

Your voice during these tough times is pure medicine sir.

I love space and I never knew this channel existing. I looked at the age of this channel and the amount of videos available and I'm overjoyed lol. I'll be watching every one.

[lukesrockhouse]

I know it is gonna be a great evening when I see "David Butler" show up in my new uploads.

Mr. Butler, I have seen all of your amazing and informative videos, and you are greatly appreciated! I have learned so much from you. Hope you are doing well!

[alfredlukasek]

Just found. Excellent. Love the pace/tone. So many YouTubers speak to fast and rush.
This is perfect.

David, by showing us such beauty and all of it accompanied by such glorious music, you appease the soul, and that makes you both a teacher and a healer. Thank you.

[kpk]

What kind of human down thumbs a video like this? Thank you David for your highly educational and calming videos and of never being afraid of the answer "We don't know."

[tavanium]

Your channel is very much appreciated Mr. David Butler. I've had an overwhelming fascination with outer space since childhood and your channel simply makes me feel the infinite youthful wonderment I felt then. I look forward to each and every video. Thank you very much.

[robertsparkman]

Far better than anything I ever saw on TV.
Thank you.

[Clutchpearls]

I watch you before bed with my headphones in, nobody does it better then you sir! The calming music in the back, with your relaxing, knowledgeable, voice, it usually takes me everything in me to stay away for half of the program, so two days for one documentary, that's only if I really try hard. Thanks for your passion, love of educating us who love to know more about this incredible universe-- multiverse & beyond, we are not even a speck of sand in it all, literally microscopic at best!

[michaelknapp]

Isn’t just amazing that we have these pictures? Newton and Einstein would be blown away with what we see these days!

[samaraliwarsi]

These videos are amazing. Simple images and voice. No modern graphics needed. Everything is in the stars to see

[MontyCraig]

Another "How Far Away It Is" Thank you so much Dr. Butler! Love your channel!

[immersifiedclips]

This is by far one of the greatest shows on YouTube and should deserve it's own YouTube space on the front page. If you ever see this David, keep going with this style. We keep returning to this and many of your older ones so much. Maybe create space travel simulations from us to more and more distant spaces! That would be insanely good!

[SevenFootPelican]

I love your videos, David. I fall asleep to them. The magic and majesticness of them all. It's like being read a bedtime story every night. It's beautiful.

Listening to the narration is good, but letting your mind consider the stars while listening to the music in awe inspiring.
