Your excitement while speaking captures my attention, like I can't miss the next minute. You are a most excellent Geek (said with ALL due respect), and you do an excellent job speaking and informing us (average humans) about space and what Hubble finds in a way that makes me want to learn more.

These videos are excellent. Much better than many TV docs about space.

A well done video. I am very pleased to have viewed it, and enjoyed the information as well as the speaker very much. thank you for posting this.

6:25 -- when he took the little box and expanded it- and you could see GALAXIES beyond the nebula--- that just blew my mind!

Thanks. Wish I had time to produce them more often.

Incredibly beautiful. So surreal, and mysterious. Total awe.

Telescopes are designed to detect much, much more than the human eye in sensitivity, resolution, and wavelength range. The human eye view would be pretty fuzzy, very faint, and rather colorless (faint objects are perceived as gray). Even flying to the Horsehead in a spaceship would not help much, as you would be closer to the cloud, but it would be spread out across the sky. The two effects cancel each other, and the brightness would be the same. Only the stars would be brighter.

Dear Dr. Summer, you are so so AWESOME.

Excellent enthusiast talk, good explanation of how this beautiful small zoom-in the Horse-head nebulae was made!

Just wow! Thank you so much for putting this up; it's so fascinating!

I have the complete Hipparcos catalog with 3D positions. As you correctly state, these roughly 100,000 stars are just the brighter ones and cover the whole night sky. With over 40,000 square degrees on the sky, that's an average of 2-3 per square degree. This Hubble image is roughly 10 square arc-minutes, or 1/400th of a square degree. So Hipparcos is not much of a help.

Dr. Frank Summers describes just the way our uncle tells us with love and affection. One doesn't need a superstar or a bimbo to attract young minds to astronomy. Dr Summers loves to make it so simple that you don't realise when the episode gets over. It is only when he says Thank you, we know that it is about to get over. Regards

The Horsehead is one of my favorite objects but this peek in is incredible! Thank you I'm an amateur astronomer but with skies deteriorating this arm chair stuff aint too bad. I'm hooked.

Thank you so much for the videos ! Wonderful pictures, and good information. Your enthusiasm for the subject is evident.

Those pictures are amazing. Such detail despite the incredible distances involved. I think my mouth actually fell open when you revealed the infra red horse head pic. Great work people.

This is so incredebly beautiful. Thanks a lot for doing what you do! :D

This show is amazing!! I'm learning so much with every video. Thank you!

Hi. I'm Dr. Frank Summers. I hope you enjoy the episode. Please ask questions and I'll check back periodically to answer them.

Love your videos and enthusiasm, Dr. Summers. I would say that I would find it interesting to know the relative scale of what we are observing. How many light years across -- or Solar systems, or some other measure that provides context -- are the images in the pictures and film? Thanks!

Thank you for creating this video and your continued work. A question that always bugged me. Are there any imagines of the Horsehead nebula showing the nebula expanding? Or are all imagines taken (since the camera invention) always look the same because not enough time has passed?

As a very young child I knew about the horsehead nebula from my copy of The Golden Book of Astronomy. I was transfixed by it then and had wild imaginings of someday flying a spaceship around it and seeing it from all sides, inside and out. Guess that someday is now. At least as close as it gets. Your enthusiasm is infectious and makes me regret not following my early passion for astronomy. I ended up majoring in mathematics which was academically my worst subject almost from the start. But still easier than astronomy. Thank you for sharing your work through these wonderful presentations. I wish I could have had you as a professor!

Fascinating. And so well made. I love these videos. Thank you.

My Favorite of all constellations! I love what orion has to offer. So awesome to see!

The HH nebula is a dark, dense, gas cloud. These clouds form by gravity slowly pulling together the gas and dust between the stars in our galaxy. Such gas is mostly hydrogen and helium (as is most of the universe), with a small smattering of heavier elements like carbon, nitrogen, oxygen, etc. We expect Hubble to be usable for several more years. I'm hoping it lasts until its 30th anniversary in 2020.

really really love this show, hope you never quit :)

Yes, there are stars between us and the Horsehead Nebula. The HN is about 1500 light-years away, plenty of space for intervening stars. Since the nebula is opaque to visible light, any star atop the dark nebula in a visible light image must be in front of the nebula.

awesome! Thank you a zillion time for this amazing work More more ❤️

This is so wonderful to watch!

Dr Frank Summers your the best !! Keep on with this great work

That was amazing, great work

Wow, so amazing what you are all doing at NASA. I think astronomy is so exciting all the different means you are creating to observe the solar system and the universe! I really feel that this is a very exciting time of discovery in astronomy! Thanks so much for making this possible for us non-scientists to see and explaining thing so well!

Rock on! It is amazing what you can discover on your own with a simple camera these days too, just by pointing it up and clicking away. I highly recommend giving it a try sometime :)

I'm the kind of person who would watch it over and over Mr.Summers. It is interesting how you see level 5 galaxies in the backround which I mean galaxies billions of light years away when I say level 5. An example of level 5 galaxies would be the Ultra Deep field.(Tim)

Winterweib: I feel the same ,,,but this is actually what all great scientists and thinkers experience. "The more I know the more ignorant I become." Welcome to the club!

Dr Frank Summers is great at explaining such massively complex things easily understood by layman. thank you Dr

Honestly Hubble and Nasa need to make many videos like this, explaining what people see in famous space related images. It is ok to back down and explain to people that what they see isn't what they expect. There has to be some kind of CGI involved, some kind of image manipulation involved, some kind of color correction sometimes even done manually by artistic impression, and sometimes what you see is not in the visible spectrum but in some other wavelength that you cannot see.

Spectacular! Wow, wow, WOW!! I have no idea, how it took me over a year, to find you.

Nice work guys! It's a beautiful image. I'm looking forward to pictures from the JWST!

It looks like a great fountain of foam or sort of liquid cotton falling from a font. Heartbreakingly beautiful as are all Hubble's pictures but some are so awesome, (and I mean that in the great classical sense, not the "awesome" of someone's new clothes), they just push you back in your chair with your eyes wide trying to take it all in and your mouth open with astonishment.

Thank you for watching.

Such incredible beauty and an excellent presentation.

The horse head nebula is my Fav object in the night sky. Thank Dr Frank for showing us such wonderful images

I've seen the horsehead nebula through a club's telescope I had checked out. Honestly I was very disappointed in what I could see because it's actually relatively small compared to the Orion Constellation and oriented so the muzzle was pointing up I didn't recognize it for what it was for at least 30 seconds. The way everyone talked about it I expected something huge and breathtaking and what I got was "oh, that's it?" Pretty much turned me off to doing my own deep sky observing and I settled into close stuff like the planets but even those are disappointing after seeing all the pictures in Astronomy and Sky & Telescope. I was excited to see Alpha Centauri when I went on the tour to the southern tip of Baja for the Solar eclipse of 91 because I could see the two separate main stars through my 4 1/4" Meade scope. This video gives me a whole new perspective of what there is to see and how inadequate our natural eyes are for seeing most of it. There's another nebula I've heard of and wonder if you've done a video on or maybe are planning one, The Southern Coal Sack. I've only ever heard this one mentioned in science fiction stories and only rarely then. The people in the ship were on the other side of it and seeing all the things it blocks. Obviously fiction but with your techniques we might get a glimpse of what's really there and I'll bet it's not nearly as dark in other wavelengths as it is in visible ones.

That's awesome how they layer them in order like that to create that effect

Excellent video, Is actually mind blowing. Thanks a million - light years!

Who knew? ... Only recently found my way here. I am a budding artist seeking to make somewhat realistic cosmic paintings. And how could you scientists not find the awesome art that I am seeking. My perception expands. This one and the Pillars of Foundation are beyond anything I had imagined. BTW it is so clear once you explain it in artistic terms... You guys rock! (even if I am 7 years late!)

That infrared photo of the whole region does look like stuff randomly drifting and forming into strands, but in that one dramatic section, where the horsehead is, it looks like something being driven, like an eruption, or two explosions intersecting.

love the talks Dr Summer

Absolutely astonishing visually

It's amazing. I'm speechless and that's not often happened. Great! Our universe is overwhelming.

Thank you Mr Frank Summers!

0:56 there is a galaxy right up the right shoulder of Dr Summer !!! hhhaha Sir you are awesome .

very good programme thanks

Great video!

I wish I had been an Astronomer. Thank you for these. I shared the heck out of 3 of you vids already. in a couple groups.

great job with the horses head nebula

i love these episodes

It takes (for me as a layman) real work to get to gripes *what* is out there, and *where* it is, and especially what is known, and what isn't. One starts out with the model that everything not on Earth is on "The Heavens", but going from the Solar System, to our stellar neighbourhood, to the milky-way and then to the near galaxies, and off to far away galaxies, there are so many orders of magnitude… "The Heavens" is not a sphere around us, and to grok this vastness is amazing…

First rate astronomy video with beautiful images!

Very nice! Thanks

this man is so awesome! mr. Frank Summers :)

this channel is awesome

Yes to Stereo 3D! :) Going to look forward to that!

This was very knowable video.

This all reports and massages are very important for physics students. thank you,

Imagine what the night sky would look like if our Solar System was 20 light years away from the Orion and Horse Head Nebula's ...WOW!!

My astronomy club has a 16 inch Mead Schmitt-Cassegrain telescope, SCT, we can see the Horsehead and they use a Hydrogen Beta filter. For the HH even in visible light it is awesome to see it with your own eyes. I cannot see it at all with my personal scope, it is only 6 inches and even with the proper filters it just doesn't gather enough light for visual. With long exposure photography I could take a picture, but I'm not into astro-photography except simple non-long exposure pictures.

Ignore all the KZread wannabe hacks that read some wiki page 5 mins before recording, Dr. Summers is the real deal.

Cosmological redshift only applies to galaxies, not stars. The expansion of the universe stretches the space between galaxies. The galaxies themselves are gravitationally collapsed objects and are governed by their own self-gravity. Hence, the stars in our galaxy show doppler shift due to motion, but not cosmological redshift due to expansion.

WOW! Thank you!

I'm just amazed!

Great show loved it. I am inerested in astronomy I have an HA filter when will I be able to get an infered filter for my telescope so I can view in 3 differentl light forms?

Dude, Starting at 05:09 would make one cool ass screensaver!!!!!

Love this science stuff.

Omg it's awesome:O!!!!

Very good and cool

VERY INTERESTING

It looks like a sad horse wandering off into the distance. It also looks like a distressed ghoul with hollow eyes, bony hands and flowing rags for a garment. It's leaning forward with its right hand on the side of its head.

WOW....superb

thanks!:)

Sucked in like light to a black hole. Love it.

THANKS❤️✨

Videos Muy Buenos.Deleite Para La Vista.Super.

Прекрасно!

The other thing is that one starts out thinking that sooooo much is known (and it is!). But there is still soooo much to learn! E.g. one would naively assume (as I did) that for every star we can observe telescopically, and for which we have determined the position and spectral-type and what-not, that the distance is known with equal precision. There is still so much to survey, whether it is stars (and exoplanets!), or asteroids, or galaxies, or KBOs. And don't mention the Oort's cloud!.

Nice!

are senses, are environment...and so on. technology: quantum computers uses atoms to make multiple processes all at the same time(i can go deeper into detail if you dont know how computers and quantum computers work) but in the research of quantum computers, shows that atoms can think TO SUM EVERY THING UP: since atoms can think and we can think and be aware, all of the energy out there in the infinite universe+all of the extra dimensions of m-theory and the unknown can also think and be aware

I see now there are a lot of assumptions built into the depth perception of what you see through the telescopes. I was wondering how depth perception was known and see now it is a lot of guess work, such as the way you put together the 3d video of the nebula.

Dr.Summers how was the HH nebula formed? What is it made of exactly? How much longer will Hubble be usable?

Hi Frank. Why do some stars have those 4 rays coming out at 90 degrees to each other? I once had a spectacular mind absolute elsewhere experience where I became space for a few seconds and out there in space, I saw that same effect on stars.

wow, fantastic 3D model!

Maravilloso

Dr. Summers I have a question! First of all thank you very much for your spectacular and very informative videos. If you could see out there with your naked eye, how looks like? Let say that you are recording a video and trying to take imagines from space, exactly how your eyes see all those stars and planets, could you make a video to show us exactly how is out there? I am very curious to see how looks like our UNIVERSE without any special effects. Could be possible A Video to show us? Thanks

It would look redish white. So much out there we can't see with our naked eyes!

I wonder for how many stars in that image there is information from the Hipparcos satellite? I guess it would be a lot of work to incorporate that, and in times of sequestration there aren't probably the resources - but wouldn't that be cool? One thing I was wondering while watching: In the animation there are stars in front of the horse head - is this actually the case?

How fast would you estimate one would be traveling to get that moving view in real time?

Awesome

hi Frank, i was looking at the horsehead nebula and what it looks more to me is a headless woman walking swinging her arms more than a horsehead .

i have read somewhere that all the pictures that the Hubble made were coloured in by people, so is this true? and if they did so, does it mean that all those objects photographed by the Hubble are colourless?

thank you. astronomers should watch the mouth of hoarse head nebula
