Good Vishual, Very Infomative.

[directorygod]

Cool, Thanks for shared.

[ngeliatduit]

Good!! Thanks

[distractionxx]

I would give it way more star ★★★★★★★★★★ great stuff

[MyDavidsun]

thanks

[iz2sicc]

One of my bucket list items is to view the stars through one of these telescopes.

[mjusiqtube]

Informativ, interesting and a excellent presentetion.

[sIatnican]

its like hes hawing truble ouderstanding this

or is he just camera shy

[bambobhat]

Nice presentation, informative. Must try to control excitement (although it is hard about these type of topics). Try to minimize errors while speech.

[turtlepturtle]

@bambobhat

r u a critic or something? y do u care

[darkskies11]

@bambobhat ''Try to minimize errors while speech'' What does that mean, if your going to post critical comments make sure you minimise your own mistakes first.

[wordpresswidget]

Interesting stuff. I am left wondering why there are gaps in the wavelength graph of 30 Dor #15 and not in the graph of HDE 26981 D.

[MattyCosmics]

Brilliant

[Yesitis808]

Oh my Scientific Method, how amazing and awesome the universe is.

P.S. Worst punchline ever.

[slave880]

@agpennock smartass

[rationalargument]

Cool story, bro

[slave880]

why do i feel this dude bullshitting, only 3 dot of lights and he made it into a 14 minute of interesting story.

[shoa31]

Suns and stars are beginning to be more like human with social attitudes.

[O2BSoLucky]

Is it just me or should it be called the 'puppy nebula' instead.

(gotta just love Pareidolia)

[DayDark87]

Your so fat, you kicked out a 90 Sola Mass star from the Tarantula Nebula!

[TokerMate]

Hoe's Universe - Unfiltered. - What I heard at the end.. sounds like a porno lol..

[joeoli1]

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

[bary1234]

This is fascinating, thanks for posting.



[Phyrexious]

What a refreshing video! The guy explains the information in a very relaxing way.

We need more of this.

[mrrockyrooster]

Did he say a star cluster ejaculates?

[SpeedFreakNO]

Should be: Sounds long to me, not I.

[kubush]

There are 8 people that don't appreciate the beauty of the universe.

[BasherCoon]

@kubush Nah, 8 people that wanted more than remedial astronomy.

[kubush]

@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]

@kubush Oh, no I never said that it was deserving of a thumbs-down. But I can see why some people would. I mean, really, do people out of 6th grade STILL need to know what 'light year' means?

[kubush]

@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)

[adsensus]

@kubush more than likely they just missclicked.

[YuceBaal]

@kubush

add me

[Nohrel]

interesting things

[easyben21]

how are they able to zoom in so far its mind bogoling u get pictures of 170,000ly away and its great resolution

[Judicial78]

It was a rebel star with out a cause!

[JadeChaos]

I love me some Hubble <3

Thanks for posting!

[JadeChaos]

I love me some Hubble <3

[BFDK]

Very interesting, thanks for posting the vid.

[Projoiner1]

Liked the video, thanks for the share

[sushanalone]

I dont get it,how can people dislike such a post! Probably cos there is no mention of god.nonetheless tx for the post and keep the good work up Bestofscience.

[TheFaustianMan]

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.

[1acroyear1]

@TheFaustianMan I gave it a thumbs down on your behalf. But only because the speaker made such a fascinating subject so boring.

Plus I'm also out of work.

But yeah. Wings Around the World.

[N1ntenOwned]

God damn, people thumbed it down, get over it. Stop thumbing up comments that just state how many people thumbed it down. Back when youtube had the star system, there was no way we could know how many one star ratings there were. No with the like system, everyone thinks they're fucking Einstein because they know how many thumbs downs there are. Damn thats annoying.

[HaleyMary]

The telescope. That is awesome! It sounds so simple, yet so fitting!

[ManDudeYeah]

D is for  dookie.

[NATASONE]

That star got dumped for a new star. I hope it at least let it take its things.

[ddh540]

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.

[BlizBob]

@ddh540

It's all about the vertical black lines in the spectrum.

When the star moves away from us the lines are shifted towards the red end of the spectrum and when it moves towards us the lines are shifted towards the blue end of the spectrum. The ammount of the shift depends on the speed.

So in order to know how fast it is moving towards or away from us you need only to take one measurement of the light coming from the star.

[dogbishop]

@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.

[bimblinghill]

@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.

[DukeNukemIsHere3]

This was actually very informative and interesting!

I enjoyed the presentation very much. Thank you!

[Daneus05]

good vid, this guy explains the basics well.

[NTROPYK]

great use of a flat panel, i've never seen anyone present with one that way.

[TAz69x]

That's Yao Ming's custom iPad

[Katalyzt]

Informative ★★★★★



[666norton420]

@Katalyzt you and your star text K! lol

hope you're doing well!

;d

[Katalyzt]

@666norton420

Wow, it has been a long time. Yes, I am well, and yourself?

Katalyzt

[TheRationalizer]

Fan-fucking-tastic!

[nishbrown]

Troubled stars need to deal with their problems, not run from them.

=-P

[dreadpiratedan]

i think the fact that V.L.T. stands for "very large telescope" means there's hope for humanity yet.

[goodvibrato]

imagine what it would be like if you could float in close proximity to all these massive stars without getting incinerated....

[karadan100]

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 :(

[Garbimba1900]

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?)

[Nohname1]

Wow I know nothing about the skies in the southern hemisphere. I didn't know about the Magellan clouds. For me a galaxy in the night sky is a little dot. Now I know I'm missing out.

[urumqilik]

LMAOOOOOOOOOOOOOOOO HAHAHAHA Cock blocking is universal

[julsHz]

Thanks for the post-- going to Chile in January and I need to brush up on my southern hemisphere sky!

Cheers!

[Dextomus]

3 rednecks have seen this video...

[anmoose]

This is a SUPERB presentation! It could have gone on for another hour, easily.

[thexsoar]

Keep looking up!

[sharpkeet]

@sharpkeet

[thecosmicgoose]

i like turtles

[botlight]

Bullying got Universe Aproval as well,, lol

[LiberAnarchy]

This is awesome!

[DeathBringer9000]

those spectrographs look like bar codes

[greyareaRK1]

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.

[fknugly222]

He's good. I like how he answers the questions that i'm thinking.

[muzammilali007]

I love all your channels.

[thebigJ1er]

Why does such a small galaxy have such a large star-forming region?

[dlite922]

@thebigJ1er

I'm also a student of astronomy and here's my best guess. Whenever a galaxy is destroyed (scattered) the remaining bunch have less gravitational forces acting on them and they only have each other. They get closer and closer and form massive clusters and nebula such as this.

Again. Total guess on my part. I'd love some more educated guesses from an astronomer.

[julsHz]

@dlite922 --Hi. You're on the right track. Recall that stars are formed in cold H II regions, but they usually have a catalyst for collapse- ram pressure, maybe. Or in the case of this irregular galaxy, which may have been formed by a galaxy collision or near miss, the catalyst could have been this interaction. Many irregular galaxies have these 'star burst' regions where the gas and dust is dense and cold-- but we really don't know exactly why. We're much better at the 'how'!

[julsHz]

@thebigJ1er Lots of gas and dust-- it's called a cloud for a reason! Stars are formed in cold regions of gas and dust that gravitationally collapse. But there is usually some catalyst, some outside pressure that starts the collapse. This is an irregular galaxy, maybe formed from a galaxy collision, or a near miss. We don't really know. But this might explain the 'star burst' region in the dense gas and dust region-- the nebula. Hope that helps some.

[myshoescramp]

I doubt this info will be all that useful to me but I just can't help but get sucked right into it! it's just so fascinating!

[qtzlctl2012]

Do you not know how to film several takes and edit?

[AtheistKiwi]

I need to watch out for these.

[azenenc]

Go invade that cluster and arrest the bully. LOL

[dafttool]

Damn interloping stars. Don't they know that you're supposed to dance with the star that brought you?

[nhmllr725]

Oh so this is how stars move out of the gas clouds.... Good job!

[lilsorms202]

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.

[goog2k]

WHY does this silly egomaniac keep putting his big ugly MUG in the picture???

Who want's to look at him?

[TreyNitrotoluene]

Homewrecker!  Poor star.

[CoolConejo]

Yo!, Ive been there!, Its alright, not bad place, might go back soon.

[dafttool]

We need a "sanity check" done on what's happening right here on Earth. :-/

[MegaManRetroX]

3 People Disliked, lol. Science Hurt Brain!!! Blargh!!!

[Hazelrat10]

Love the speaker. He NEEDS to be on this channel more often.

[TheCurmudgen]

I love astronomy. So fascinating, so beautiful and also mysterious.

[ericluc13]

god i love science especially about fascinating stuff like universe n galaxies it always excites me [thumbs up if u feel the same way ]

[Rationalific]

Very informative! Easy to understand but not too dumbed down, so that I could really understand what the science of it is like.

[bovoice]

Such a big iPad!

[JerkyChid]

Poor star, got dumped

[gulllars]

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?

[MegaSuxification]

yea i have been to hde269810. it's actually called "blurrrrrrrpishnurrrrrrkit" i know because i was abducted by the grays back when i was an airforce test pilot at groom lake (some call it area 51) we where trying out this anti-gravity propulsion system we recovered from that crash in NM when a strange light appeared out of no where (tractor beam) then next i knew i was aboard the greys craft and on my way to blurrrrrrrpishnurrrrrrkit.

[TheSpankymonkey]

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.

[mallardhead]

Great presentation! Thanks!

[Jaksary]

The speaker is really good!

[drche420]

Great vid

[kandiman7979]

how could u thumbs down a science video? damn ignorant rednecks prolly.

[phuhcue]

@kandiman7979

90 pound weaklings?

[kandiman7979]

@phuhcue to name a few im sure lol

[gunnerdan70]

@kandiman7979 Nah it's the fundamentalist who come here to troll

[kandiman7979]

@gunnerdan70 lol really. damn ignorant sheep. must suck to be that lame and brainwashed and not embrace science. yes. lets not go into space and enjoy humanities death if we dont. yes. lets do that. and such and what not. lame lame lame. sad really

[antimicrosofty]

could it be that this star was not so massive when it was kicked out, but have accumulated mass on its way.

[drche420]

@antimicrosofty

It seems possible, just no way to know yet.

[AManOfHope]

@antimicrosofty It did just speed through a huge cloud so you would think. You got me wondering now too.

[djkoch65]

I love science!!!

[LAnonHubbard]

Very informative and captivating delivery. Thanks!

[RTRVII]

fantastic video!

[saxmanchiro]

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.

[MoltenArtGlass]

Pretty cool.

[keviar245]

LOL captions are so funny! "named after magellan who discovered them on his penis"

[silksism]

@keviar245 lmao, these captions made my day xD

[eddiequest4]

TFA - Totally......... Awesome.

I haven't been this enthusiastic about astronomy since Carl Sagan.

Thanks for the efforts.

[jab0805]

Is it possible for two or more stars to be so massive that they could be drawn together by their gravity and form an even more massive star? In an area where there are an abundant amount of super massive stars would it be possible for say a thousand or more to form a star so large it collapses in on it's gravity? Is 30 Dor #16 far enough away from the large cluster to escape such an event?

[julsHz]

@jab0805 Generally speaking, something catastrophic happens when two stars get that close. They will have a 'relationship' for some time, but it usually ends badly. We think gamma-ray bursts happen when 2 neutron stars eventually collide, for example. Or one star can suck material from a close companion star, increasing the mass of the 'sucker' to the Chandrasekhar limit (1.4 solar masses), and supernova. These are SN Ia and we use them to measure great distances. Good questions...

[ToastMaster623]

1:22 Lol "that ima-...immense"

[MrWajax]

Neat stuff!

[quosmo1]

i love this guys explanations, it is informative and hints at the methods enough without condescension.

[gunslinger7878]

Awesome!

[Kargoneth]

Very nice presentation. The presenter actually has charisma. Nice information. I've never seen a gravitational slingshot like the one he explained with the 3 stars. Most intriguing. Thanks for the upload.

[216trixie]

This guy did a good job, talking for almost fifteen minutes.

[somejackball]

purple shirt eh? ya know... Tinky Winky is purple, and he eats Tubby Custard.

[tetekofa]

Nice presentation !!

[luckystrke]

GREAT video! Thank you

[tonybeir]

I really like this guy, very friendly and warm presentation and of course very informative.

[BigMTBrain]

EXCELLENT presentation, IMO!!

[macks7241]

@BigMTBrain

won't you be my NEIGHBOR...?

[NotSoOldHippy]

Eeeeww! Birth!



[korzen321]

He really sounds nervous, But he did a great job. Nice explanations, thank you!

[neonsilkworm]

He's clearly amateur in reading a teleprompter and delivery. They really couldn't have done a re-take where he knows "our" left from "his" left? Also, he did not support the binary star theory with observed examples of tight binary star systems in the cluster. These kinds of things are important to keeping a scientific video interesting.

[bengacris]

@amcbirds lol you asshole like to start shits he?

[yamaguchiyo]

wonderful in depth explanation! we haven't seen a video like this on this channel in a while. =)

[coopersnoop]

This guy is wrong! Obviously God made it 6000 years ago and that's final!! ;)

[CosmopolitanNo1]

@coopersnoop; You are quite mistaken. It was 6000 years and 2 and a half month ago, you dumb-ass. Don't you know anything? Do like I did: Ask God. He'll tell ya. ;-)

[Kargoneth]

@CosmopolitanNo1

I asked God. He said he didn't exist. I then enrolled myself in an insane asylum.

[CosmopolitanNo1]

@Kargoneth: :-)

[sabertooth1980]

@Kargoneth I would have just said that I was an atheist and be done with it. Then I would move on with my life.

[MJAstronomyRocks1]

@coopersnoop LOLZ.

[frackcha]

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!!

[darkouljp]

great video....

I love this channel!!!!!!!!!!

[anonforuz]

I wish class was like this.

[lokoxxxxx]

There is 1 person to stupid to get this and 193 smart people:-)

[inquiry10]

this reminds me of many a science lesson in high school but now that i am older it seems far more interesting :-)

[DreadRaptor85]

"A" star got cock blocked by "C" star.

[Gr33nM4chine]

@DreadRaptor85 Hahahahaha. Totally! And that after spending a million years chashing after it. Damnit i feel for star "A"

[Direkin]

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).

[truvelocity]

@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.
