Same dish as Owen's Valleys', including the ao setup, just has a nice helmet :D. other than that just normal calib's such as pointing and flux. The dish is like a sail in the wind so pointing can be tricky, sometimes nodding off 10 arcsec in a 2h period. For the 230 ghz receiver we do use a chopper for the secondary, chop every sec or so
Nice video! I just wonder...for the astronomers who get into the field because they like the equipment and being on the summit, I wonder how things are changing. Long ago people looked into an eyepiece with their eyes and made exposures on photographic film at the telescope in the cold dome. Then came ccd cameras, and observers still used them on-site but from a warm control room. But with the development of robotic remote-control and space-based telescopes, I wonder how long it will be before all astronomical research observing is done over the internet from your home institution - or maybe it already is? Do astronomers still work at telescopes, or is it only the technical staff that is up there nowadays?
Hi Poly. This is Alain Khayat, the scientist operating the telescope here. This was ten years ago now and we were the very last people to do science with the Caltech Submillimeter Observatory before it got decommissioned. It needed a lot of work to operate this beast and be able to do science with it. Remote observing is currently the thing to go for nowadays, but there is still the need to have technicians on the telescope to cool down the dome, fill in liquid Hydrogen/Helium, etc, and make sure the observing night goes according to plan!
Hmm I always wonder how I can help to support this video series... Obviously providing an interesting place to visit for the show would probably help out the most but not everyone is in academics so I'm left to think about donations or some other way of helping out negate the cost.
it varies but still a tropical climate 45-90 degrees at the top you can only be there for 5 mins then you gotta go back down. night show at gift shop is great.
I have now discovered this through the videos of a RUclips star that does a complete documentation of this. A great video put to music is called Hawaiian heavens part 3 song is called alone tonight. I truly know nothing ,and amazed at this whole new area of life.my question to the scientist still there all these years later , not what you have seen, that's a secret,but why at sunset sun takes square star shape, switch. From round? Happy days
Damn, why are science PhDs so much cooler than Humanities ones (all we do is sit in our office reading)? And why did I have to be born without the science gene? So many questions... Hmmmm, ramen noodles...yum.
It is unimaginably arrogant that they would build these telescopes so close to an active Volcano less than 30 miles away. They should be building telescopes for space.
@@Physics072 The statement was true, AND I will keep dreaming FI, I can put the tiniest light on my boat and it can be seen a mile away at night. But a flag the size of the one on the moon cannot be seen in broad daylight from a mile away. Try to pay attention, and try to dream. Those are the hallmarks of genius (Btw, I do doubt a candle flame could be seen from earth with even something as powerful as the Keck scope, (dont really know!), but that fact is not even relevant to what I said in my original comment). Try to say something intelligent about the subject at hand, rather than trying to prop up your own sagging ego by making comments about others (supposed) frailties.
I thought they'll show us different pictures taken from telescope. Other than 'molecule', i don't think she has studied anything else in her PhD. Was a useless video. Wasted my time.
Yuh, us americans put men on the moon We make fantastic scopes But wow, you measure things in meters Huge congrats to you. But thats about it But we can use meters just as easy as feet. Quite hilarious that you watched a vid about this fantastic scope, and that is all you can come up with Lame

Yesss! Fun, informative, well made, shot and edited! A pleasure! Moaaaaarrr!

@@Al-sw1cp Thanks Dr. Khayat for the reply. You work in a fascinating field. Best of luck in your research!
@@Al-sw1cp You will loose the "Feel" of the scopes being one more step removed from the hardware.
The segmented primary mirror doesn't do real-time correction right? Pretty they are active optical systems rather than adaptive!
Such a great video, I have been there 3 times, star gazing is my favorite part of Hawaii. Thanks for sharing,!!
At 7:24 I think he said "orrery", not "horaire".
This girl went to my high school 10 years ago - cool to see what she's doing now.

How cold was it over there?
it varies but still a tropical climate 45-90 degrees at the top you can only be there for 5 mins then you gotta go back down. night show at gift shop is great.
Great video guys, keep them coming
awesome place and awesome video! Thank you!

it started with ep0 :)
Divide it by three and you'll be fine. It still gets you more accurate results than most astronomers. :P
7:27 The correct spelling is orrery.
3:23 Astramenomy
7:36 AstraRamenNomNomNomMe =D
Horaire? ...Orrery, perhaps?
Everyone's born with a science gene. :)
Divide the number of feet by 3.28 and you have meters.
that's cool as the co2 drops of as well as the o2 that means its not a frightening experience-phew!!
Такое душевное видео! Спасибо!
Um, so the choices would be: shitty life or shitty life plus gazing at the stars from the top of Hawaii?
Damn, why are science PhDs so much cooler than Humanities ones (all we do is sit in our office reading)? And why did I have to be born without the science gene? So many questions... Hmmmm, ramen noodles...yum.
He's "calibrating" a THz wave reciever with a 109MHz signal?
Too bad they just show "impressions" rather than actually impressive technical stuff....
It is unimaginably arrogant that they would build these telescopes so close to an active Volcano less than 30 miles away. They should be building telescopes for space.
Pretty sure when he said 'horaire' he meant Orrery, but you're a phD now so you knew that.
10:48 "[...] yeah, this is my life!" And burping is socially acceptable up there :-)
I will be using this for convincing a friend to study astronomy or planetary science instead of history or literature (tajel would be mad)
Excellent thank you
Nice!!!
Ramen... Hmmm.....
Ahah I'm glad to see I'm not the only one who heard that.
Can see a candle flame on the moon...but can't see the american flag. *whispers..."because it isn't there."
duh.
because the candle makes light.
the flag doesnt.
science will put any conspiracy theory rest.
too boring i guess
@@37rainman Keep dreaming if you believe that is true.

That moon of Saturn looks very familiar to the moon because it is! ITS all made of ice just like the moon and the universe is concave!
Mahalo for sharing.
my vibe
Mauna kea mountain shouldn't have these buildings. It is sacred land.
Film Me Your Head. Great name!
He looks very nervous to not say the wrong thing of course he had to reference ET and all that bs lies!

I would kill people to work there. =)

the singing in the car made me stop watching. 😥😹😹
Actually the choices are crumby life plus gazing at the stars or crumby life plus big paycheck..... Come to the dark side....bwa ha ha ha
Measuring in feet....so annoying xD Americans.
Yuh, us americans put men on the moon
We make fantastic scopes

Huge congrats to you. But thats about it
But we can use meters just as easy as feet.
