Denis Barkats and friends show us the BICEP-3 telescope at the South Pole. More Denis videos from Antarctica: http://bit.ly/Antarctica_SS More telescope videos on Deep Sky Videos: http://bit.ly/telescopetours Video also features Kimmy Wu and Jimmy Grayson. Denis filmed these during the Summer 2015-2016. He is based at Harvard University.

I couldn't get around that horrible smudge on that coating layer of one of those detectors!
exactly! my OCD governs me to clean that but I can't!
Peter Bucek I thought first that it was a smudge, but then I decided it was something underneath like a bracket.
I, too, was bothered!
Its a microwave sensor, remember, a smudge isn't going to have the effect you might at first think!
What Mark Tillotson said! Smudges matter when it's an optical or more energetic telescope, but microwaves are completely unaffected by that.
That helium line noise is really cool
The "next" video after this that YouTube has decided to give me is "proof" that the Earth is flat because planes are apparently crashing into the invisible shield that holds in the atmosphere. YouTube, please...
I know what you mean. I wish there were some way to block certain content or at least particular channels
Yup it is bizarre how they decide what you might like to watch next.
Using the "not interested" selection and specifying that you are not interested in that channel works as well as telling YouTube you are not interested if you have already seen the videos. Just empty clicking on your part and no change in YouTube suggestions.
Earth is round tho
These Antarctica videos are plain awesome ! :)
After a lifetime of working with radio waves I just can't get used to terahertz level microwaves that act more like light. Using an optical lowpass filter to screen out the infrared light from a radio telescope just blows my mind.
yep transitioning thru dc to daylight is amazing!
sneaky alumin(i)um at 5:12 Brady
Normally I'd advocate the international spellings of things, but the British chemist responsible for its name had chosen "Aluminum" in the first place, and it was the Americans who used "Aluminium" until meddling from pseudo-linguists got everything mixed up. In a way, Aluminum is the proper British way to say it, and neither spelling can be called wrong.
Victoria M you are incorrect. He first chose Alumium, changed his mind once to Aluminum, then changed it again to Aluminium.
I can´t get over how young and yet competent they all seem to be. That´s pretty awesome.
These people weren't just picked from the street I guess ;)
i afraid those are Harvard and Cali Tech people.
And that Kimmy Wu is definitely a South Pole 10/10
These people are pretty much born smart.
Dark Sector: South Pole sounds like the ultimate 80s movie :D
omg dream job, dream location.....
There's a smudge on one of the detector modules.
We've missed you, Deep Sky Videos! <3
What is that chirping noise around 6:40 I noticed the MRI at work makes the same noise.
The pulsetube cooler does this sound as it cools the device with the helium. MR equipment has a similar cooling system as that one needs low temperatures for omptimal image quality, too.
Helium cryocoolers make that sound. MRI machines use them to cool down its magnet coils so that they are superconducting and can make a strong magnetic field.
Smudges on the reflective detector thingies at 1:42
1:48 at row 4, column 4
Somewhat Snakes Should not make much of a difference. Its better to ignore smudges and clean the lenses as little as possible. You'd be surprised how dirty a lens or mirror can get before the image starts to suffer. As an amateur astronomer I only clean my telescope every few years when it's finally caked in dust and the image starts to degrade. Otherwise it's best not to touch, as every time you clean you cause wear and scratches to the coatings and the glass/mirror no matter how careful you try to be.
At 10:08 be careful you almost press the auto-destruct button.
2:02 - that anti-reflection coating looks awfully reflective.
I thought that was a warning alarm or something, nope just cooling systems :')
Brady you should go to Antarctica! I love Denis' videos but it would be amazing to see you there.
0:30 I would so absolutely whip a handball over there... BONNNNGGGG!!!!
I love these Antarctica videos! Brady, how many more are there planned, can you tell us?
Now, that's a place to visit! :-)
That is wildly complicated. Love it!
Wow, awesome! :-)
I ache with sadness that I will never get the chance to spend time at the South Pole.
If it's an antireflection coating, why can we so clearly see our reflection in them? :P
00:46 T-Shirts!!! Warm indeed.
I feel like I understood at most half of this video 😅
I hardly understood anything at all. But I wanted more anyway :D
Who the F touched the detector at 1:46? Ooh god, this grinds my gears so much, my OCD is screaming!
You dont have ocd.
It's a 4K camera!
aaaaaaah one of the detectors is smudged. I can't stand it
Impresive :-)
Enjoyed Denis's David Niven look
I love Kimmy!
awesome to have a video again!
Nice mustache :D
wow that is amazing
Awesome! Thanks!
Who put a smudge on my detector?
Fantastic insight into hard work, in the field science, passion and dedication. I wish I could go
Wow!
awesome!!!
Hey, you guys rocks, keep it up.
thank you :)
6:47 Make that canary shut up! ;-)
Everything about this installation is awesome.
I saw this thumbnail and assumed it was a music video from mrsuicidesheep.
Goes to show how out of this world this place is.
John Waters at the South Pole.
Juan Gonzalez and freezes
Wish I were there!..
The sound of that helium cryocooler is so beautiful.
i saw a smudge on the light detector glass lol..oops lol
Why are they not wearing protective/clean gear when around highly sensitive equipment?
Either they're sloppy and incompetent, or it doesn't matter like you think it does. I vote "it doesn't matter like you think it does".

And the award for coolest sentence ever spoken goes to: "those are the helium lines going to the pulsetube cooler trying to cool down the inside of the cryostat."

I can almost hear O'Neill sighing "get to the point."
Ccoommer - 2016-11-12
Indeed.

Tokyotokyo Tokakyoku coldest indeed! :-)

And it makes the exact sound it should based on its description.
