This video was filmed and edited by James Hennessy
I really love Dr Grey's voice. It's quite soothing.
I've always thought Dr Gray would make an excellent narrator for audio books
Just saw M8 through my telescope for the first time tonight. Awesome.
4:33 thanks for the new phone wallpaper
4:35 is pretty too
Watched this video a few times, and now I'm sharing it again. Megan's voice is so soothing, and love hearing her delve deeply into the way she explains these objects! She's a cuppa in human form! And I say that as an american!
How is this the first time I watch a video of this channel! It's amazing!
IMO one of the best on you tube. Enjoy!
Check out other Brady’s channels if you didn’t know. Also Hello Internet podcast!
Your accent and tone of voice are super soothing !
So much talk about "hot young stars," I thought I was watching TMZ.
When I first found Bradys channels, I first watched for the content. Nowadays I mainly watch for the people: I just love them all, hearing them talk, seeing them looking straight at the camera, imagining they were watching me back... - imaginary friends, who are actually real people; seemingly finer people and certainly more interesting ones than the ones I know in real life, as they share all my interests and tell me bits and pieces I didn‘t know in ways I can understand. I do understand that so many comments are about the people in the vids, as we are all trying to relate to our heroes. Man I wish Brady could have done those vids with Carl Sagan, or Richard Feynman etc.
I absolutely love this channel. Thank you for the opportunity to learn and be amazed at how the Universe manifests itself.
I love your work Dr. Gray. Worth mentioning is that the two photos look so very different because of the color assignments made by the proccessor on individual wavelengths of light that will link to the majority of elements found there. Also, I believe that Hubblesite/ESA has published a similar photo to your first, that is actually be a nicely constructed mosaic. M-8 is one of my favorite emission nebulae as well, being as a truly awesome object with hundreds of things going on in and around it. Great work and thank you.
Dr Gray, your presentations and situational descriptions are among the best in terms of being interesting and understandable
Starnado!!!
Happy Canada Day Dr. Gray!
I really can't wait for the amazing new insights James Webb is going to give us!
I've watched at least 99 % of all the videos on the different channels by Brady, and this video is one of the absolute best!
All you need to do is add space sharks, then you know you have the most epic of space tornadoes. The kittens riding rainbow tacos will have a tough time. That's a beautiful picture
I’m new to the channel but loved the format of this video. Its like having a 1 on 1 chat with a professor about her favorite celestial object.
Yet another "toner destroyer prints"... :-))))
Very nice video, as usual!
You are getting better at producing those videos and your hosts are getting more comfortable and interesting. Keep bringing them on!
Fantastic video about one of my favorite Messier objects. In fact, I was observing M8, Saturn, and a naked-eye asteroid, Vesta, with binoculars last night. It was perfect timing (and coincidence) to releasing this video.
Space tornadoes is an awesome new fact that I'll have to share at my astronomy club's next public stargaze.
1:43 That's totally unbelievable!
Brilliant - both Dr. Gray & Lagoon Nebula.
Dr. Gray is starting to pick up a British accent ever so slightly
Starting? I believe the Dr. has been residing in UK for decades and is of Canadian nativity.
the Canadian nativity is similar to the regular nativity but the three wise men bring beer, maple syrup, and bacon and the donkeys are replaced with moose
+AndorianBlues Those are still much better gifts than frankincense and myrrh. Gold is hard to beat though.
golden crispy kraft dinner
Happy Canada Day!
4:49 That's not a Bok Globule, that's CLEARLY a cat walking across the telescope...
Her voice is ASMR smooth.
What a carnival of wonders.. epic vid!!!!
Mind melting... How dense is the space tornadoe? What's the temperature difference between the"surface" and the core? How is temperature even measured when it's at this scale? So many questionsssss
Space tornadoes? You can't fool me, you've discovered the hiding place of the Maquis! It's the badlands.
Nah, those are just funnel clouds. It's only a tornado if it touches the ground. Good luck with that in space.
I think you'll find the correct term is SHARKnado, not TORNado
Glad I could be of assistance.
Yay, it's Dr. Meghan Gray!
Lots Dr. Meghan. Great info, welcome back!
Love your videos. Also happy to see that the schlumbergera (christmas/easter cactus) you had in 2013 is still in your window.
One of my favorite Messier Objects! Thanks for the video.
Breathtaking and eloquent in both view and personal description, thank you for your sharing
In the same way that nuclear fusion is always 20-30 years away, the launch if the James Webb telescope is always 3-5 years away. So we might have a bit of a wait for those better images.
Bok globule. I love that name.
Thank you so much Dr. Megan Gray,
My looking at the Lagoon Nebula has been greatly enriched. :)
Word of the day *Bok Globule*
Repeat 10 times
What a great video, Brady and Dr. Gray!
"...Hot Young Stars..."
My band name detector was like "PING PING PING!"
"Space Tornadoes" has to be a rival band. I'm seeing an astronomy-inspired musical series.
Well, I'm off to the bush with the telescope to have another look at this tonight :)
As an Australian I lay claim to M8.
Check, M8!
Very educational. Loved it.
Thank you for these amazingly explained of series of videos!
Wow a tornedo half a light year across! sheeeese!!
Every time she says "space tornadoes," i say YEAH!
great video, so interesting!
Me and my friend just so happened to set a course for Herschel 36 in elite dangerous
The Great Nebula in Carina deserves a a whole series of videos.
A new Deep Sky Video!!! Awesome!
Something something,... Gr8 video M8, I R8 8/8..
g'day m8
M8 the Aussie nebula
Maaaate 😉
I'm a simple man. I see Meghan, I click
Love that mars photobomed this.
happy canada day!
Wonderful video, and I have to ask why it took you so long to get to M8? Thank you Dr Gray, thank you James Hennessy, and thank you Brady.
yay Meghan!
It’s so beautiful.
Dr. Gray is actually turning gray
Awesome information. Thank you for sharing.
The dust clouds around Hershel 56... 36? Whatever she said the cloud below that star looks kinda like a Kokopelli
Yaaaaay!!!! New video!!!
It's beautiful!
This is really cool m8.
Kokopelli lives in a nebula! Early Native Americans were right to paint him all over the Southwest US.
Hi great vid I do deep sky work seen this through my 20inc s c telscope
Fuckin space tornado's..... FUCKIN SPACE TORNADO'S !!!!!
Fascinating theory! Makes me wish I had a 100 foot mirror & observatory!?!
I must say tho that it can be hard to see Dr. Gray, perhaps in the future you could add some zoomed in shots with a big arrow pointing out the scientist talking...
Yay
It's all pretty neat.
Plz tell me the mn of som stars or nebula which i can discover with my normal telescope.. I will wait for reply pizz mam
Dear Brilliant Friends,
It looks like I will be filling in for an astronomy talk for a friend for one of the hyper-expensive "dude ranches" for the rest of the summer.
I'm working on a basic stellar evolution / cosmic evolution / scale of the universe type thing.
But also the importance of science research...
What are YOUR favorite "There is no money in pure research and then there is" items (yup, electricity is a favorite, so are the general relativity equations that make your gps work)
ooooo yeaahh!
It's not linked in the description, but don't forget to watch the incredible Deep Sky Video presentation of M20, aka The Day of the Triffid!
1:27 Are there any Astrophotography geeks that know if it's possible to get a shot of Mars like this with a combo of filters, exposures, and focus where it would look more interesting? Obviously someone could edit any image by adding a picture of Mars pasted over any background, but I'm more curious if someone could pull off a shot that can capture everything in this exposure as shown with a true infinite depth of field to capture Mars and the background. I don't know if Earth/Mars would move enough to be problem for the exposure needed. I'm mostly interested if a camera exists that can capture this much dynamic range and if a near infinite focal length is possible in this kind of setup.
-Jake
Hmm. I’m not an astrophotographer, but what I do know is that depth of field generally decreases as the focal length increases. It would be a very high focal length with an incredibly wide depth of field. That may make for a ludicrously gigantic optical manifold, but I am not totally sure.
Ryan Johnson
Yeah its been awhile since I messed with a DSLR in a studio, so my terminology could be a bit rusty as well. I've only done product photography professionally for a few years but that was a couple of years ago. I haven't done much outside of that environment.
-Jake
Yeah, with exposure bracketing and compositing... Mars will move during the multiple exposures, perhaps not enough to matter. Might as well just paste a Mars shot in using Photoshop, most of the 'award-winning' photos you see these days are just composited. Add a sunset and some wolves!
in short the dynamic range is too extreme. the planets are so bright they are captured via capturing video (up to 180-fps) and stacking the sharpest frames. deep sky photography (eg M8) is made up of long exposures stacked (eg in this RGB image they were probably about 5 minute subs). also Mars would appear tiny (if it weren't over exposed) in this field of view - planetary images are captured at long focal lengths to obtain detail.
No simply not possible with the distances between Mars and the background nebula. There is no way to focus both at the same time. But even if you could you have to do some very fancy attenuation of Mars' light so it wasn't a super bright washed out spot. Photoshop it.
Awesome
Mate=m8 so funny
gr8 vid m8
What does it mean that "Hubble has CHOSEN..."
It feel that this lagoon have enough content to fill several videos...
HOT, YOUNG STARS IN YOUR AREA
No Brady?
So where would these tornadoes be on our earthly scale? Or do we need to make a new one just for them?
epic!
kinda cool to see birkeland currents in space. eventually people will give credit to the electric universe theory. it only explains and correctly predicts nearly everything. "there is electricity in space, but it doesnt do anything".... really? looks like its doing something in this picture for starters...
Ionized hydrogen is just bare protons.
Yes, but the glow is emitted when an electron re-combines with the proton to become an atom again.
And space unicorns have been seen in this region.
"Space tornadoes" ....GR8 B8 *M8*
How dense is the nebula in comparison to earths atmosphere at sea level?
Who else thinks the cloud structure next to the Herschel star looks like a ballerina tossed in the air by a partner?
Hey there's the new oil fields, someone get Texas on this.
You don't need to dig for this fuel.
Can we see M8 not to far from the sunrise in the horizon placed at the right of the sun??...
I would name this the chameleon nebula.
I wonder if JWST has already imaged that coccoons
Anyone else see a face at 4:07 and 6:45 ?
u aight, m8?
the kessle run
are all those beautiful photos actually real? I mean like how close are they really to a (let's say) "raw" image..?
Many space images of gas and dust nebulae are taken in false colors (to differentiate elements and such) and after very long exposures. This allows scientists to do, well, science. If you were actually close enough to see these objects at the same resolution, they would look much more drab and faint. You may not see much of anything at all, besides a barely perceptible haze. That said, the objects themselves are VERY real.
Most astrophotos are heavily processed. But that doen't mean what you see in them isn't real, it's just enhanced for clarity and colours.
thanks dudes..
Faceless just saw the lagoon nebula today, I can say for myself that even though you may not see much color, it is still an experience of itself. I recommend looking it yourself if you ever find yourself under a clear sky with a telescope, look for M8.
