Jorge and Alex travel to the highest peak in Hawaii for a look at how Astronomers figure out the molecular composition of far away stars and planets. Visit our website: phdcomics.com/tv
CORRECTION: Actually, studies have shown that the relative partial pressures of O2 and CO2 don't change much with altitude in the atmosphere up to the mid-stratosphere due to convective mixing. This means that the air is moving around in such a turbulent fashion that any "settling" of the gases due to gravity is mostly canceled out by remixing due to air currents. There is still less oxygen and less CO2 at higher altitudes, though, which combined make it harder for your body to take in oxygen and to recognize this deficiency. Our original explanation came from what we heard from several astronomers and it certainly made sense, but it just goes to show you that nature always surprises and that the proof is in the data.

Yesss! Fun, informative, well made, shot and edited! A pleasure! Moaaaaarrr!
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!
@@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.
Such a great video, I have been there 3 times, star gazing is my favorite part of Hawaii. Thanks for sharing,!!
awesome place and awesome video! Thank you!
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.
Great video guys, keep them coming
Everyone's born with a science gene. :)
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

I have now discovered this through the videos of a UA-cam 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
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.
Nice!!!
Pretty sure when he said 'horaire' he meant Orrery, but you're a phD now so you knew that.
Ramen... Hmmm.....
it started with ep0 :)
Haoles never learn do they
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.
The segmented primary mirror doesn't do real-time correction right? Pretty they are active optical systems rather than adaptive!
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.
@@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.
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!
Такое душевное видео! Спасибо!
I will be using this for convincing a friend to study astronomy or planetary science instead of history or literature (tajel would be mad)
This girl went to my high school 10 years ago - cool to see what she's doing now.
my vibe
that's cool as the co2 drops of as well as the o2 that means its not a frightening experience-phew!!
Divide it by three and you'll be fine. It still gets you more accurate results than most astronomers. :P
Aole TMT!!!
10:48 "[...] yeah, this is my life!" And burping is socially acceptable up there :-)
Divide the number of feet by 3.28 and you have meters.
Ahah I'm glad to see I'm not the only one who heard that.
At 7:24 I think he said "orrery", not "horaire".
Um, so the choices would be: shitty life or shitty life plus gazing at the stars from the top of Hawaii?
7:27 The correct spelling is orrery.
He's "calibrating" a THz wave reciever with a 109MHz signal?
Too bad they just show "impressions" rather than actually impressive technical stuff....
I would kill people to work there. =)
Excellent thank you
the singing in the car made me stop watching. 😥😹😹
Mahalo for sharing.
Horaire? ...Orrery, perhaps?
Measuring in feet....so annoying xD Americans.
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
Bought!
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.

7:36 AstraRamenNomNomNomMe =D
Film Me Your Head. Great name!
Mauna kea mountain shouldn't have these buildings. It is sacred land.
He looks very nervous to not say the wrong thing of course he had to reference ET and all that bs lies!
El único mexicano que quiere ir a conocerlo
Phil Muirhead :-)
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
