Telescope at the South Pole (BICEP-3) - Deep Sky Videos

[@thebeardedastronomer]

I love that Denis contributes so actively, awesome for an actual professional astronomer to be doing insight videos

[@Ensorcle]

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."

[@ze_rubenator]

I can almost hear O'Neill sighing "get to the point."

[@Knots_]

Indeed.

[@iambiggus]

Tokyotokyo Tokakyoku coldest indeed! :-)

[@ddegn]

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

[@MephLeo]

It's so cool to have a peek on the complexity of scientific instruments and how they work!

[@surrog]

These Antarctica videos are plain awesome ! :)

[@whiskeythrottle9369]

I can´t get over how young and yet competent they all seem to be. That´s pretty awesome.

[@JaapVersteegh]

These people weren't just picked from the street I guess ;)

[@dontquestionmyname5490]

i afraid those are Harvard and Cali Tech people.

[@auto_ego]

And that Kimmy Wu is _definitely_ a South Pole 10/10

[@heru-deshet359]

These people are pretty much born smart.

[@Shinzon23]

Old people tend to die in places like these from stress alone

[@Lagrange_Point_6]

Everything about this installation is awesome.

[@genius27641]

That helium line noise is really cool

[@lunasophia9002]

We've missed you, Deep Sky Videos!

[@JustOneAsbesto]

Best telescope tour.

[@big0medium]

awesome to have a video again!

[@spicyrazz]

I love these Antarctica videos! Brady, how many more are there planned, can you tell us?

[@goodboid]

Absolutely bloody fascinating!

[@peterbucek2136]

I couldn't get around that horrible smudge on that coating layer of one of those detectors!

[@zviratko]

exactly! my OCD governs me to clean that but I can't!

[@seanrodden6151]

Peter Bucek I thought first that it was a smudge, but then I decided it was something underneath like a bracket.

[@JediNg135]

I, too, was bothered!

[@MarkTillotson]

Its a microwave sensor, remember, a smudge isn't going to have the effect you might at first think!

[@victoriam586]

What Mark Tillotson said! Smudges matter when it's an optical or more energetic telescope, but microwaves are completely unaffected by that.

[@Bring_MeSunshine]

Fantastic insight into hard work, in the field science, passion and dedication. I wish I could go

[@unclvinny]

That is wildly complicated. Love it!

[@Jacxel]

Enjoyed Denis's David Niven look

[@RMoribayashi]

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.

[@justanotherdrunk]

yep transitioning thru dc to daylight is amazing!

[@jeanvallee9340]

Hey, you guys rocks, keep it up.

[@DeepSkyVideos]

thank you :)

[@pauledwards5573]

Very interesting. Thank you very much

[@Fimwind]

The sound of that helium cryocooler is so beautiful.

[@LazerLord10]

It's a 4K camera!

[@willrun4fun]

What is that chirping noise around 6:40 I noticed the MRI at work makes the same noise.

[@24680kong]

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.

[@ledzeppelin4892000]

There's a smudge on one of the detector modules.

[@danielramirezcruz.2209]

Super video... great work I love it thanks..

[@UAPJedi]

Wow, never knew there was a telescope down in the South Pole, why isn’t this on mainstream media?

[@cemoguz2786]

What kind of question is this? do you live in a island full of smart and people with culture. People are more interesting at how much did kim kardashian poo yesterday. You need to lover your expectations about people we are handful here.

[@EebstertheGreat]

I would love to know why refracting telescopes are ideal for this type of work, since they are generally very rare.

[@moechano]

Really nice

[@mechfeeney]

Was surprised to see the detectors facing up outside of cleanroom and also no clean garments. Not much of a concern?

[@sterby1]

Who the F touched the detector at 1:46? Ooh god, this grinds my gears so much, my OCD is screaming!

[@hydrolaural]

Awesome! Thanks!

[@zapfanzapfan]

Now, that's a place to visit! :-)

[@garronfish8227]

No leave it to the scientists

[@pierreabbat6157]

How do you power the telescope in the winter? I remember hearing about some data collected by various telescopes, including one at the South Pole, and they had to wait for the weather to warm up so that they could transport the hard disk containing the data from the South Pole.

[@colinbischoff4383]

BICEP3 produces about 15 GB of data per day, which is transferred north via satellite.

[@flymypg]

So many questions! If I understand correctly, BICEP-3 will observe more channels with greater sensitivity over a larger area, and part of that area is intended to obtain a strong galactic dust signal to aid subsequent analysis of darker areas. Do I have that right? - Will BICEP-3 observations include the same sky patch as BICEP-2? - Is BICEP-3 working as well as hoped? Reliable? Good data? On schedule? - Has the galactic dust model been refined enough to not limit BICEP-3 analysis? - How soon are initial BICEP-3 results expected to be published? - How much BICEP-3 work is independent of the next Keck Array upgrade? About that last question: I'm mainly wondering if BICEP-3 work is being optimized primarily toward the next Keck Array, possibly limiting it's own science objectives.

[@colinbischoff4383]

BICEP3 is basically observing the same sky patch as BICEP2 (but a bit of a larger area because of its larger field of view). BICEP3 is working very well, first science results coming out soon. BICEP3 is observing at lower frequency (95 GHz) than BICEP2 (150 GHz), so it should be less affected by Galactic dust. Our understanding of the dust in this patch of sky has been improving with Keck Array data -- it's an incremental process at this point. As of 2020, BICEP3 is operating alongside the BICEP Array, which is a replacement / upgrade of Keck Array.

[@checktheskies5040]

Seen the Nemesis star recently?

[@Viniter]

what a cool place!

[@daniochoa2110]

50k!?? That’s impressive!

[@bangsarumsaatiniadalahrusi4636]

Sometime, please try to observe every edge of the Antarctic using telescope from there... and post what you see, upload its video here so everyone can see too 🙏

[@apolloskyfacer5842]

?

[@teeanahera8949]

It is not an optical telescope in the visible light spectrum buddy.

[@teeanahera8949]

Oh and that might be possible with an ordinary telescope if the EARTH WAS FLAT but it isn’t so they can’t see the coast as it may be over the horizon. Mind you they are at 2,835m above sea level.

[@vlogerhood]

I ache with sadness that I will never get the chance to spend time at the South Pole.

[@guyh3403]

Wow!

[@alannoorkoiv6281]

Wish I were there!..

[@misterkefir]

So technical.. wow.

[@Braeden123698745]

That lensy telescopy see fary thingy is smudged.

[@KevinSmith-qn8fn]

wow that is amazing

[@manolimylopotamos8597]

This is at Amundson Scott right?

[@Sokol10]

Yes, in the South Pole (geographic) station.

[@fnersch3367]

How far away from Amundsen-Scott is this facility?

[@colinbischoff4383]

About 1 km, just a short walk.

[@markkemper1327]

so where r the pics r videos duh

[@Keex11]

Use some of the Kimtech wipes on the detectors before assembly :-D

[@NANA4bacon]

awesome!!!

[@dmk351]

Dark Sector: South Pole sounds like the ultimate 80s movie :D

[@SomewhatSnakes]

Smudges on the reflective detector thingies at 1:42

[@Pferdekopfnebel]

1:48 at row 4, column 4

[@salty-as-heck9915]

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.

[@apawar280889]

00:46 T-Shirts!!! Warm indeed.

[@jkr48]

I love Kimmy!

[@loge10]

I agree-incredibly cute and smart. An unbeatable combination.

[@seffundoos]

There is a smudge on one of your detector modules...

[@Acidtrip138]

this might be dumb... but what are they looking at? just cosmic background radiation (i know u have done videos but i'm still not sure what it is i know it was created at time of big bang) or is this a telescope in the classic sense and it imaging stars and galaxies

[@colinbischoff4383]

BICEP3 is designed to observe the Cosmic Microwave Background, not stars and galaxies.

[@Perktube1]

2:02 - that anti-reflection coating looks awfully reflective.

[@colinbischoff4383]

That AR coating is designed to work at 3 mm wavelength, not optical.

[@Bwyan]

Why is there no subtitles for the host?

[@alexandrugheorghe5610]

Probably because the camera is standing just next to the host's mouth and, thus, we can hear the host more clearly unlike the other people which are at a distance with huge background noise covering them.

[@youtubeusername1489]

Now that is a sci-fi looking instrument with sci-fi sounding sound.

[@PinkChucky15]

Wow, awesome! :-)

[@JaapVersteegh]

Cool

[@astropgn]

Man, that lab biceps are huge

[@ym6294]

Interesting how in the South Pole telescope you never seen pictures of space like you do in America telescope and many around the world. can someone tell me why I can't find any from this South Pole telescope of pictures of space. South Pole seems interesting place to look at stars and planets but yet no pictures from that place🤔

[@BentConrod]

sup no br 🤔 Hmmmm... I'll have a crack at replying.. Scientific instruments designed specifically for tasks such as Background Imaging of Cosmic Extragalactic Polarisation simply don't produce the same results you're familiar with from conventional astronomical telescopes? 2:49 The crazy cold South Pole environment makes it easier to get the telescope's antenna temperature down to 4K, helping to minimise antenna noise, which masks the extremely weak cosmic microwave background being captured. Also, there wouldn't be another location on the globe with lower man made RF polution.

[@JonasHortell]

What is the temperature of that place generally at?

[@UCreations]

en.wikipedia.org/wiki/South_Pole Between -25C in the summer and -80C in the winter.

[@JonasHortell]

Thank you, I was mostly wondering about the specific area of the dark zone, air-currents and the quirks of the area will heavily play into what temps they get.

[@picobyte]

liquid nitrogen is A waste product so it's very cheap :) Transporting the stuff is most expensive.

[@JonasHortell]

Helium tho, thats a luxury.

[@picobyte]

***** A special isolated tanker can be used.But still it's very dangerous stuff to drive around with.It's the danger level that makes transport troublesome and expensive.

[@EdmundKempersDartboard]

DSLs and BICEPs at the south pole. Sounds like a party.

[@michaeltaylors2456]

[@Valkyrie612]

Why are they not wearing protective/clean gear when around highly sensitive equipment?

[@RonJohn63]

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".

omg dream job, dream location.....

[@OOZ662]

The "next" video after this that KZbin 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. KZbin, please...

[@PCBSLC]

I know what you mean. I wish there were some way to block certain content or at least particular channels

[@TCA744]

Yup it is bizarre how they decide what you might like to watch next.

[@AustrianAnarchy]

Using the "not interested" selection and specifying that you are not interested in that channel works as well as telling KZbin you are not interested if you have already seen the videos. Just empty clicking on your part and no change in KZbin suggestions.

sneaky alumin(i)um at 5:12 Brady

[@victoriam586]

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.

[@Starblind11]

Victoria M you are incorrect. He first chose Alumium, changed his mind once to Aluminum, then changed it again to Aluminium.

[@amoose136]

If it's an antireflection coating, why can we so clearly see our reflection in them? :P

What will be the reaction if there are no B-mode evidence in the CMB? A collective OOPS?

[@julessmith2]

Those fingerprint smudges on the detector did my head in. Shouldn't they be clean?!?!

[@PCBSLC]

I don't know about this particular sensor, but there are usually expensive and exotic coatings on astronomic instruments that would be damaged in the process of removing the smudge. While the smudge itself doesn't affect the sensor much. I'd love to hear from someone that knows for certain though

[@mienaikoe]

Don't know for certain, but smudges won't affect microwaves much. They typically only affect visible light.

[@colinbischoff4383]

@@PCBSLC The anti-reflection tiles are quartz, so pretty durable. But the smudge also isn't a big deal because it is so thin compared to the wavelength of the light (3 mm) that BICEP3 detects.
