That periodic table gives so much perspective to the "we are all made of stardust" statement. It goes one step further and shows you which specific stardust you are made of. Really cool.
What if black holes somehow made dark matter? That sounds dumb, but if the galaxy is very thin because it contains very few black holes, couldn't that also be the reason for its lack of dark matter? Is there evidence of dark matter in galaxies with very few black holes? Would galaxies exist for very long without a massive, dense center to orbit?
7:55 Looks like their control software being run under Fedora linux with KDE environement. Software is presumably custom, written using some old-school toolkit like wx-widgets/motif. Some windows are run through VNC (btw who the heck needs VNC when you have X11?!). Personally I'm interested in nerdy video tour on software setup controlling such big telescope facility. It is probably too late to do requests, Scott?
Telescope control software has a couple different layers, but the NIRI interface at 7:55 controls the components inside the NIRI instrument assembly, which is bolted onto the bottom of the telescope. It would've been written by staff software engineers working on the NIRI team (some of whom _might_ be actual, trained software engineers, but who are just as likely to be people with Astronomy degrees who turned out to be better at coding than doing science). Each instrument is itself custom and typically includes novel technology or techniques (hard to get grant funding for reinventing the wheel!), so the software design is necessarily custom. In the Near-IR wavelength range that NIRI works at the usual observing strategy is to take a large number of relatively short exposures, so disk space disappears frighteningly fast and observatories with Near-IR instrumentation have to think a lot about data storage and archiving. In practice the total setup is usually a little rough around the edges, but you can get away with it because the number of users is relatively small and they all tend to be pretty smart.
I was able to use the NOT telescope, located in The Canaries remotely, in November-December as part of a Course, and it was really awesome to be able to view some distant galaxies, and get some spectra from them too. A once in a life time opportunity.
Bad luck mate , maybe the weather will co operate next time . Still informative and interesting to see and hear how it works , and the girls where very enthusiastic to talk about the job at hand.
Hey scott, can you do a science video on Columbia? I have always wondered what would have happened if they had discovered the damage, was there a rescue plan to recover a full shuttle crew from orbit?
There was no rescue plan. There were actually some indications that there might have been damage based on footage they had, but someone would have had to make observational confirmation, and in absence of any potential rescue, they decided it was better for the team not to know that they were almost certainly going to die. If things had been rationed properly and they'd rushed some refurbs and checks on shuttles they had on the ground, they might have been able to organize a rescue mission using another shuttle and some astronauts that would have been available, but only if they'd checked as soon as people reviewing the footage noted the possibility of damage. It would have been a rush-job, and the whole time the crew would have known that the odds were good that they were, in fact, going to die no matter what they did. They changed their operations after that incident, and never sent missions up unless they had a crew and another shuttle on standby, and I think they took some additional measures to try to prevent impacts like the one that caused the initial damage, so the standby crew wasn't ever necessary between when they resumed the shuttle program and when they shut it down.
So it isn't possible to build megastructures in KSP? A rotating skyhook is at the lower end of the size range of megastructures, so if it isn't doable in KSP then the same is true of Lofstrom loops, orbital rings, O'Neill cylinders, planet-sized parasols, stellasers, and so on. Instead, we just potter around with refinements of Robert Goddard's century-old invention.
Seriously, a few of these makes not only rockets but airline travel and cargo shipping totally obsolete. You get all the delta-v you need to get people and cargo anywhere in the solar system, as well as rapid travel between major cities on Earth, for a fraction of the energy use of current systems: ua-cam.com/video/LMbI6sk-62E/v-deo.html
You can make mega structures, ubioZur welding and tweakscale makes that possible, but interacting with orbital bodies on that kind of scale might be a huge problem. Heres a channel that tends to push the limits of what can be done with KSP. ua-cam.com/video/fJXdxUsQhqE/v-deo.html Oh..... OMG, it's an orbital ring around kerbin itself. :p
That was my original plan, then they kept bringing people in and we didn't have time to keep adding and removing mics, so I used a pair of studio mics and a lot of post filtering to reduce noise.
Takes more than "1000" astronomers to run the show. Techs and maintaince is required. People to build, fix, clean, drive, data collection, ECT. Takes a team, not just one person.
if you're near Texas. McDonald Observatory let's you view through 8" and bigger telescopes in their Star Party. for cheap. or if you're anywhere near an observatory that offers a star party...go do it.
In an older Brady video on the Palma telescopes, they mentioned that they removed an eyepiece because it stopped people from working. And he sight must have been crazy
Aloha Scott. I'm from Big Island and used to work just down the road from those observatory offices at 'Imiloa Astronomy Center. My cousin still works at Gemini, and while I'm glad you enjoyed your visit, I'm a bit disappointed that you didn't at least acknowledge the controversy surrounding the telescopes as it relates to the exploitation of public land as part of a general trend of colonialist ideology towards the islands. I didn't need you to come down one way or the other, but I feel by not acknowledging it at least you are on the side of trying to ignore a problem instead of solving it. If you were not made aware of the controversy the entire time you were visiting the Astronomy community, then I apologize as the fault for that obviously is with your guides who didn't want to tell you about it. Gemini itself is one of the most obviously egregious examples of the continued exploitation of Hawaii as it's twin partner in Chile, literally an identical observatory, pays over a million dollars a year for it's rent at the top of it's mountain while Gemini Hawaii still pays $1 per year. Hawaiians like me are not anti SCIENCE but anti EXPLOITATION and in most every other place where Astronomers wanted to build on the mountains the region received windfall benefits in exchange for building on public or tribal land while the astronomy industry in Hawaii is insular and mostly benefits people not from Hawaii.
This is one of several videos, I was saving that discussion for when I got to the summit. I did discuss this with my guides and with other residents and obviously I'm sympathetic to both sides. I'm glad you shared your opinion.
Mahalo for your reply and I'm looking forward to your future video which discusses the subject, and I apologize for coming on strong . Outside of Hawai'i news and social media, there's very little coverage on the controversy, and lot's of misinformation is spread about what the reasons behind the protests are, so I want to make sure the right message gets out since you have a wider audience than the issue normally reaches To try and keep it brief, the Native Hawaiians and White Scientists are not fighting with each other over an ideological battle between preserving and honoring native culture against scientific exploration and discovery, in fact the two groups aren't in conflict at all since by and large those scientists are all liberal types who are all about honoring native cultures and Hawaiian culture itself has a deep appreciation for science. That is a false narrative done by the local media here because the real culprits behind this whole debacle are as insidious as they are boring since they are a small group of corrupt mid level government bureaucrats who are exploiting a state land management loophole for personal gain at the expense of the entire public, but that doesn't sell local papers like insinuating a race war looming in paradise!!! Love your videos Scott, I became a fan of yours years back while I worked at 'Imiloa and your Kerbal Space Program videos and talking about space exploration gave me the knowledge that led to my main student project on applying traditional Polynesian celestial navigation techniques to modern space missions on other planets. After all the ability to determine your latitude on any rotating body with nothing but your mind and the stars might be a useful skill for future manned missions.
And I always thought the amazing thing of operating such a telescope was being on top a the mountain in the cold and thin air... You kinda destroyed my view the heroic astronomers ;)
First of let me tell you your grammar is awful so odd to criticise me for that ("is a series of"? "if your attempting"?). You also seem to have assumed I'm a women, which is funny but also shows you are unable to read my name. To answer your first question (I won't bother with the second since you have clearly misunderstood the original meaning of the comment): you surely can't deny that women are under-represented in science. If I had thought you would believe me when I told you this has a negative impact on people who might otherwise pursue a career in science (hence the need for inspiration powerhousejp was referring to), then I would have said that in the first place. However, your utter close-mindedness meant I didn't which was why I didn't bother before.
It's meant to convey a lot of important information to people who are working hard at 3 in the morning at 4200m elevation (even though most of the work isn't done at the scope anymore, the software is designed to cope with oxygen-deprived brains).
That periodic table gives so much perspective to the "we are all made of stardust" statement. It goes one step further and shows you which specific stardust you are made of. Really cool.
Strong, independent dark matter that don't need no galaxy.
Not to mention the strong, independent galaxy that don't need no dark matter.
not that strong. poor thing is faint and transparent. i wonder does it have any supermassive or even semimassive black hole.
What if black holes somehow made dark matter? That sounds dumb, but if the galaxy is very thin because it contains very few black holes, couldn't that also be the reason for its lack of dark matter? Is there evidence of dark matter in galaxies with very few black holes? Would galaxies exist for very long without a massive, dense center to orbit?
gajbooks interesting thought, definitely worth digging deeper

Personally I'm interested in nerdy video tour on software setup controlling such big telescope facility. It is probably too late to do requests, Scott?
VNC lets you disconnect/reconnect w/out affecting the app being viewed, doesn't it? As far as I recall, you can't do that with X11 alone.
Telescope control software has a couple different layers, but the NIRI interface at 7:55 controls the components inside the NIRI instrument assembly, which is bolted onto the bottom of the telescope.

A LOT of supervision porn :)
Awesome to hear the science explained from the scientists working there. Thank you for taking your spare time during your vacation to do this
I was able to use the NOT telescope, located in The Canaries remotely, in November-December as part of a Course, and it was really awesome to be able to view some distant galaxies, and get some spectra from them too. A once in a life time opportunity.
that's the first time I see Scoots lower body...
i feel like anytime Scott has a guest in a video the guest should introduce themselves with a quick "hellooooo, i'm first-name last-name"
This was fantastic! I hope you visit more observatories and other places of astronomical significance.
I drive down that way all the time. All the different telescopes are officed on that road. And 'imiloa is right there with its titanium cones.
Reminds me of the Great Canary Telescope (GTC) on La Palma. In the actual giant room where the mirror with instruments are it’s like a refrigerator.
Bad luck mate , maybe the weather will co operate next time .
Still informative and interesting to see and hear how it works , and the girls where very enthusiastic to talk about the job at hand.
Are they using KDE? Nice.
Loving the adorable awkwardness of nerds 😘
Shaya Nirenberg they want to fornicate) they are locked in a tower with mirror on top by vile magician McBurger)))
is the access road open to the public?

Awesome vid. Thank you Scott for organising that!
Has anyone ever done a rotating skyhook in KSP? It's a simple idea that doesn't require super-strong materials.
The physics range wouldn't let you do it. Well, You can fix that with mods but then horrible things happen.
If so then that's a deep problem because it makes KSP a mere toy where players are diverted into a sandbox of obsolete technology.
So it isn't possible to build megastructures in KSP? A rotating skyhook is at the lower end of the size range of megastructures, so if it isn't doable in KSP then the same is true of Lofstrom loops, orbital rings, O'Neill cylinders, planet-sized parasols, stellasers, and so on.

It always puts a smile on my face to see the number of ladies in labs every time i walk in one these days.
If you do manage to get up there, take a boogie board! I went sledding last time :D
In situations like this if you want better audio use lavalier microphones.
That was my original plan, then they kept bringing people in and we didn't have time to keep adding and removing mics, so I used a pair of studio mics and a lot of post filtering to reduce noise.
I'd like to be a professional astronomer, but there are approximately 1000 of them in the USA. Take a guess at how many job opportunities that means.
ibanix2 they woyld still pay you) there are still librarians)
ibanix2 what’s the worst that could happen if you went for it anyway?
Takes more than "1000" astronomers to run the show. Techs and maintaince is required. People to build, fix, clean, drive, data collection, ECT. Takes a team, not just one person.
They were hooked by his Manley charm.
gonufc yeah, like they ve never seen an old bald man before)) got to do sonething with dragons)))
*i wish i could look through that kind of telescope some day*
I'm like 99% sure it doesn't have an eyepiece.
Its just a screen like Daniel said
No one is up there

Wondering what is the Brazil part on that project..
Chile!
I saw a Brazilian flag in front of the building, but I think Brazil has some sort of collaboration in Chile part
Researching more, Gemini is a partnership between United States, Canada, Chile, Brazil, and Argentina. I didn't know that until this video :)
Oooh... It looks like Linux with Gnome 2 on those computers @ 7:18
Yep, it's using CentOS.
Hawaiian science is the BEST IN THE WORLD!
That's so fucking cool. Man, I wish I was you, but with hair.
Hair is just so high-maintenance :P
If I was him, I wouldn´t care about hair.
nekdo nikde yeah, by thid you'd care about your daughter blossoming up and telling her bf how she's fed up with KSP and VR)))))
Oh, Scott, your little boy...
Oh wow welcome to the islands! Im from Oahu
I flew back to California on Monday.
Look at that sunset!!
Awesome periodic table 5:27
It looks like they are running CentOS.
Scot gets to meet the most interesting people
parajacks4 and the lonliest fatties, and people who make battle robots) sure, it's better than breeding snails back in Scott's Land))))
And I always thought the amazing thing of operating such a telescope was being on top a the mountain in the cold and thin air... You kinda destroyed my view the heroic astronomers ;)
I think the tour guide felt a bit out of place at times because of Scott’s knowledge
I don't want to gripe too much because I appreciate the video, but I do hope the audio quality is a little better for your other videos up there.
It will be.
Fly safe!
So many women! Cool that you're showing these interviews.
I know two of the women in the second still picture; they are some of the most kickass people I've ever met.
Mostly to inspire those who were taught "gender matters, you can't do this" into realizing gender doesn't matter.
+Lord Samich Good job framing a positive comment as the hate speech *you* are spewing
There was no question, just baseless anger
First of let me tell you your grammar is awful so odd to criticise me for that ("is a series of"? "if your attempting"?).

Scott Manley... Astronomer... DJ... Hacker... Chubby girls' Knight-in-Shiny-Armor ;-)
Scott's cool, but I don't need a knight, thx
Sandwich is my meal
Very nice people!!
Video shows 666 views when clicking it. On loading it corrects to over a thousand. Very happy about that :D
Well, I guess you'll just have to visit Gemini South instead ;-)
I've been there
7:55 this has to be the ugliest software I've seen in my life
I think the colors where chosen to avoid blue light. It would help with adaptation to night time light levels.
Looks pretty standard for industrial control systems.
It's meant to convey a lot of important information to people who are working hard at 3 in the morning at 4200m elevation (even though most of the work isn't done at the scope anymore, the software is designed to cope with oxygen-deprived brains).
What does it matter as long as you get science out of it?
Looks like good (bad) old Athena Widgets on some UNIX.
probably it was made by students or by the researcher themselves for zero monetary cost.
700,000 subs
And thanks to you for this video :D
Oh god, scot please have Apple pay you to redesign their telescope driving UI or something. That hurt to look at.
I'm a backend developer, you don't want me touching UI.
"Don't worry, Hex is much more readable than decimal"
But... but... hex IS more readable than decimal...
I'm sure you could do better than whatever the "cmCtrl.dl" window is. (The one with "Altair Basic Control" at the top)
Real astronomers don't use a GUI. Real old astronomers can't spell GUI.
The software looks absolutely horrible, they need to update it to be more modern looking! Also they need a command line interface, just ‘cause.
