@Direkin As an astronomer, you are working globally not isolated in the US. Therefore, you have to use a language that is universal measurement for all astronomers. He was in a hurry not nervous. There is a time limit and when the clock was running out, he stuttered a little bit.
@ddh540 The fabric of space itself is being stretched over the eons, so on very large distance scales, the waves of light traveling for millenia are being stretched from shorter (blue) to longer (red) wavelengths, aka the Red Shift. So a star with a given spectrum should have characteristic wavelengths, but if they are red shifted, physicists can estimate how far away they are based on how redshifted the light is observed from Earth. This is the Doppler Effect. No time elapse is needed.
Great video. I wonder, with the JWST replacing Hubble would the time needed to wait for the star to move an "appreciable distance" be lessened? I think so with better resolution- anyway I love these videos :x
@ddh540 The type of doppler measurement you are thinking of is where a signal is bounced off a moving object (eg a radar signal off a car), so the signal has to make around trip. The difference here is that the star is broadcasting its own signal in the spectral lines of its light, so the information can be read off straight away.
@truvelocity Absolutely, so why wasn't he using metric units, as used by everyone outside of the US? And he was stuttering at the beginning as well, not just at the end when he was running out of time.
Bloody hell! A scientist you can understand and doesn't make you want to go to sleep! Thanks for sharing an informative and interesting Vid Thumbs up! :D
cool video, with great explanations.... id just love to be in eye shot of the binary ballet... its staggering to think about it... thanks for the upload!!
@BasherCoon So just because they had false expectations that is was something beyond remedial astronomy means this video is deserving of a thumbs down? It is clear and well made for the purpose that it was meant for.
@BasherCoon You have to understand that when they create this video they have to consider that it may be viewed by a wide range of audience members. Yes, I know what light-years are and I understand why they mention it, but I also got some incredible information about recent discoveries that, to me at least, are just breath taking. I pity those that can't see the beauty in our Universe. (not to say that you don't)
Excellent talk, but took the metaphor a bit too far. I wonder if a neutron star on the move in the cluster could possibly eject massive stars, or would it turn into a pulsar or something due to the abundance of gass in the area?
@Direkin He did it for the American audience and I believe you raised a good question as RUclips is global. So, why couldn't he, for times sake, work out the dialogue to add both measurements? For example, my Facebook page has friends from Canada, Australia, etc. So, when I say it was 70 degrees, I always say, "79 F/ 21 C today."
How do you use doppler if the star is 100k light years away. Wouldnt it take 200k years to get a doppler reading? Confusing... these enormous distances and sizes.
Aliens are obviously growing stars for their ships' engines in that nebula, and we caught the aliens harvesting one of the stars from the cluster. Duh.
I often wonder how many countless planets, gas giants, brown dwarfs, red dwarfs, black holes, neutron stars and main sequence stars are currently steaming through inter galactic space after being thrown out of their home galaxies after a big merger. I bet the prominence of red dwarfs at least, will be huge. They're just too faint to see unfortunately :(
Goddidit. I can't prove it but I just know it. He travels faster than the speed of light. He teleports where he needs to go. Scotty helps him with that. Any time He wants to visit earth, Scotty says; "I cannot do, Captain. It will blow the engines." So He just stays away and just visits other places since it will damage the dilithium crystals and the engines will explode. Just saying. Great vid and great info to help us understand the immensity of the universe.
@mxmsfuyt I just ran. I ran all night and day. :D Psst! Dr. Summers! When you said "on the right/left", you didn't account for the fact that those are reversed for the viewers. But still a good presentation! :)
The answer hasn't anything to do with gravity. It's quite clear the other stars were bullying this star. It's quite clear by the speed this star is travelling from the others it wants to get away from them.
When I was young, I thought cool. Now that I am older, and a bit colder I'm like: And this helps unemployment how? People are starving on this planet...and I fail to see how ... how this has any bearing on life? Curmudgeonism is setting in upon my old age. Even still, I gave this a thumbs up.
The host sounds nervous, but he'll get over it. Hopefully one day he'll get over the use of Imperial units (or English units as they're called in the US).
They had previously thought that the magellanic clouds were on an Elliptical orbit, new info has shown that they are actually on a parabolic orbit. Random info for those who care. XD

What I love about this presentation is that it gives us more detail about how the various explanations were tested.
Excellent talk. I'd seen a few shorts talks about that star, but he added a lot more background and useful detail in a reasonable amount of time.
This is a SUPERB presentation! It could have gone on for another hour, easily.
Love the speaker. He NEEDS to be on this channel more often.
Very informative and captivating delivery. Thanks!
This was actually very informative and interesting!
I enjoyed the presentation very much. Thank you!
I love astronomy. So fascinating, so beautiful and also mysterious.
Very informative! Easy to understand but not too dumbed down, so that I could really understand what the science of it is like.
I love me some Hubble

@Shalek i concur he is very eloquent
The universe is AMAZING! Thanks for sharing...

He's good. I like how he answers the questions that i'm thinking.
wonderful in depth explanation! we haven't seen a video like this on this channel in a while. =)
EXCELLENT presentation, IMO!!
good vid, this guy explains the basics well.
The telescope. That is awesome! It sounds so simple, yet so fitting!
great description. Thank you!
This is fascinating, thanks for posting.
Great video. I wonder, with the JWST replacing Hubble would the time needed to wait for the star to move an "appreciable distance" be lessened? I think so with better resolution- anyway I love these videos :x
Great presentation! Thanks!
Nice presentation, informative. Must try to control excitement (although it is hard about these type of topics). Try to minimize errors while speech.
this reminds me of many a science lesson in high school but now that i am older it seems far more interesting :-)
Thank you, that was very well explained!
The best explanation
Keep looking up!

thanx for the upload
GREAT video! Thank you
@truvelocity Absolutely, so why wasn't he using metric units, as used by everyone outside of the US? And he was stuttering at the beginning as well, not just at the end when he was running out of time.
great use of a flat panel, i've never seen anyone present with one that way.
I need to watch out for these.
this was good stuff. nice and relaxed.
you have some great stuff here
Nice presentation !!
Bloody hell! A scientist you can understand and doesn't make you want to go to sleep!
Thanks for sharing an informative and interesting Vid
Thumbs up! :D
cool video, with great explanations.... id just love to be in eye shot of the binary ballet... its staggering to think about it... thanks for the upload!!
"Im running away....and im never comming BACK!!!"
-runaway star
Informativ, interesting and a excellent presentetion.
The speaker is really good!
how are they able to zoom in so far its mind bogoling u get pictures of 170,000ly away and its great resolution
thanks
great video....
I love this channel!!!!!!!!!!
One of my bucket list items is to view the stars through one of these telescopes.
@BasherCoon So just because they had false expectations that is was something beyond remedial astronomy means this video is deserving of a thumbs down? It is clear and well made for the purpose that it was meant for.
really informative and interesting
I love me some Hubble
god i love science especially about fascinating stuff like universe n galaxies it always excites me [thumbs up if u feel the same way ]
these might be noob questions
but can you have a trinity star system?
what happens to the other binary star if one goes supernova?
@antimicrosofty It did just speed through a huge cloud so you would think. You got me wondering now too.
I love science!!!
i think the fact that V.L.T. stands for "very large telescope" means there's hope for humanity yet.
fantastic video!

I wouldn't talk about it as if I would have tendency to have this as a background picture...
1:22 Lol "that ima-...immense"
Liked the video, thanks for the share
very informative video
@puncheex you probably right
That was really interesting.
Hurray for science!
Physics make things move!
Excellent talk, but took the metaphor a bit too far.
I wonder if a neutron star on the move in the cluster could possibly eject massive stars, or would it turn into a pulsar or something due to the abundance of gass in the area?
This guy did a good job, talking for almost fifteen minutes.
This is a great video
@Direkin He did it for the American audience and I believe you raised a good question as RUclips is global. So, why couldn't he, for times sake, work out the dialogue to add both measurements?

Go invade that cluster and arrest the bully. LOL
How do you use doppler if the star is 100k light years away. Wouldnt it take 200k years to get a doppler reading? Confusing... these enormous distances and sizes.
Awesome!
imagine what it would be like if you could float in close proximity to all these massive stars without getting incinerated....
Damn interloping stars. Don't they know that you're supposed to dance with the star that brought you?
I would say yes to have that as backgroundpicture...
Aliens are obviously growing stars for their ships' engines in that nebula, and we caught the aliens harvesting one of the stars from the cluster. Duh.
I often wonder how many countless planets, gas giants, brown dwarfs, red dwarfs, black holes, neutron stars and main sequence stars are currently steaming through inter galactic space after being thrown out of their home galaxies after a big merger.
I bet the prominence of red dwarfs at least, will be huge. They're just too faint to see unfortunately :(
Why does such a small galaxy have such a large star-forming region?
Informative ★★★★★

great
those spectrographs look like bar codes
Suns and stars are beginning to be more like human with social attitudes.
It looks like he control the presentation with his foot.
There are 8 people that don't appreciate the beauty of the universe.
When I was young, I thought cool. Now that I am older, and a bit colder I'm like: And this helps unemployment how? People are starving on this planet...and I fail to see how ... how this has any bearing on life?
Curmudgeonism is setting in upon my old age.
Even still, I gave this a thumbs up.
I agree with your gravitational interactions but I find that it's more probable that Mario gave that star a whole lot of starbits (it's a joke, ok?)
Oh so this is how stars move out of the gas clouds.... Good job!
The host sounds nervous, but he'll get over it. Hopefully one day he'll get over the use of Imperial units (or English units as they're called in the US).
@Hooya2 Yah, would be better with Carl Sagan but...
@kubush more than likely they just missclicked.
Is it just me or should it be called the 'puppy nebula' instead.
(gotta just love Pareidolia)
@mobius1234 Not after you dad visits its not.....wait what?
They had previously thought that the magellanic clouds were on an Elliptical orbit, new info has shown that they are actually on a parabolic orbit. Random info for those who care. XD
@sharpkeet
We need a "sanity check" done on what's happening right here on Earth. :-/
@Kargoneth: :-)
Too bad that star is long dead. Sure makes some beautiful images though, and will continue to do so while it's light is still reaching us.
@DreadRaptor85 Hahahahaha. Totally! And that after spending a million years chashing after it. Damnit i feel for star "A"
its like hes hawing truble ouderstanding this
or is he just camera shy
I wouldn't say no to have that as backgroundpicture..
