Listening to her gives my the feeling the she knows why the telescope works and not the how it works -- It works when I Press this button / No.... have no idea why.-- Just somebody to me to.
What an absolutely fascinating interview and a great person to interview. Her knowledge and ability to communicate it are outstanding. Made more amazing as not a native English speaker. Loved this!
Really interesting interwiew with a very good scientist. I was only listening at the beginning and when she started to speak I immediatly recognize she was italian like me....we speak english all the same 😂. Congrats Fraser and I hope the Atlas will be fund.
Wow! Dr Cicone really went into great detail without baffling us too much. Amazing interview. Amazing brain dump! Did I hear right that the entire dish surface has to be perfect to within 20 microns at all times, or is that the positioning accuracy of the dish? Pretty incredible for something so big, outside in the desert!
What a charming and intelligent Italian female observational astrophysicist ! She seems quite passionate and driven. I hope her project gets funded and completed. Putting the 50 meter dish at the site with the existing ALMA array will be a great tool to have available.
before this video I was down a RUclips rabbit hole, finding myself contemplating the doom of humanity due to our seemingly innate ignorance, but after finding this, I feel better, thank you.
As she indicated though, the finished dish will be supplemented by an ultra high resolution scan of the surface of the dish so that software lensing can compensate for any anomalies.
manufacturing on that larger scale might be the part that will end up taking time and money --- Over budget.-- I'll predict they will find a way to make it happen after cost and time
Technology at 37:50 mentioned regenerative brake technology in Electric Vehicles and power requirements like Megapack and Solar arrays worthy of consideration by Elon Musk engineers. 😮 superb discussions!
Fantastic peek behind the real work of science and the multidisciplinary competency required to see through such a large project. Great guest, I am so happy english is the language of science it makes it so easy to access it without having to learn a language. I also enjoy the accents with which non native speakers express themselves. If I was Elon Musk I wouldn't have wasted 44 billion dollars and lost 22 billion dollars buying Twitter. I would have funded lots of real fundamental science projects such as this.
I fell into one of those AI generated Space related videos today. 😟 Then, few minutes later, you uploaded a video with you and your guest in flesh and blood.
I actually don't get what a 50m single dish can do what ALMA can't. The conversation did not provide the numbers. Its total aperture is only a third of ALMA's fifty four 12m dishes, so SNR has to be lower. Its resolution is way below ALMA's in interferometer mode. What I heard is that it would have good SNR and resolution *while* having a large field-of-view (more than one square degree), IOW: it can be a survey telescope. Which is good, no question... until you consider what enormous PITA is it to build a 50 meter parabolic reflector to ~30um surface tolerance, and to KEEP that tolerance in a high desert conditions. Compared to this, 12m ALMA dishes are "extremely easy" because they are that much smaller. Notice how DSN is *getting rid* of its 64m antennae because they are too costly to maintain (they switch to arraying several 34m antennae because those are far cheaper, AND they can do two other things at once when do not need to be in array mode!). And _these_ 64m dishes are NOT at submillimeter tolerances, and are NOT in the high mountainous desert where everything costs at least 3x more - and yet, they are too costly. There are many other things that can be done at ALMA. Adding outrigger dishes to increase resolution of the interferometer - incremental work, every new dish just adds a bit more resolution, no new gigantic costly dish designs. Adding separate correlators so that array can be split into several subarrays, this can allow to run survey, or even several separate concurrent surveys (!) with existing dishes. The usual upgrades to receivers, correlator, electronics.
Out of curiosity, if a friendly billionaire was to come along and say they want to upgrade all the dishes at ALMA to 20M, how much would that cost and what would the sensitivity and resolution increases be?
Buy more 12m dishes instead - no need to redesign anything. Interferometer resolution depends on the number and distances between them. ALMA site has plenty of space around it to add more outlying dishes.
She talked about making the telescope powered by renewable energy - I wonder if you could use the main dish to collect sunlight, lol (then I realized that since it's not an optical scope it can probably operate during the day, so that's probably out, lol.)
How are we able to get such well defined images? With the shenanigans that we have to do to detect extrasolar planets, I'd have thought such planetary discs would've just appeared as a bright blob of light.
What would it cost to build an AU-radius spherical telescope by sprinkling cubesats with cameras/antennas, using solar panels as make-shift solar sails for maneuvering, on a constellation of close-to-polar orbit around the Sun, Startlink/GPS style, using mesh networking so they don't have to be strong enough to reach Earth, just the nearest cubsesat in the constellation, and relay their data till reaching Earth? And what kind of data could we expect to get from something like that? If the cubesats were launched at the same rate as Starlink have been launched on average, how long until we could get the full sphere?
I think your forgetting -- 1 reason these type of telescopes works -- Is because -- Once the antennas are in position they don't move. We know exactly where each antenna in placed. Imagine how difficult it would be to keep them from moving / wiggling around in Spaaaaaace Look up some videos aboot what it took to make the Earth size radio telescope ( the Event Horizon telescope ) to work - The very precise timestamps that allowed the each of the radio telescopes data to be synced up.
It can't cost anything since the technology of space optical/IR interferometers does not exist yet. We know how to do it in theory, but never did it in space.
@@RectalRooter Even if you can't synchronize them with lasers and atomic clocks to the point allowing for interferometry, they could still be useful for super-resolution and light-field imaging to obtain a more volumetric view of the solar system, get a more complete view of the Sun etc
Gonna go out on a limb with an educated guess. Manufacturing that precision on that large of an area is going to be difficult and costly. Even with a CAD design - It doesn't mean it will work in real world environment.. Just the temperature differences will be a bitch
Hi, Fraser. Could you please help me understand the details of her design and application. It was a bit challenging to keep up with her because her accent is not familiar to me. Please, sir.
If you turn on the Closed Captions, you can read along with whaf she's saying. The video has mostly been properly captioned; only a few errors, easy to fill in the gaps if you can also hear her.
If they are new they are only new to us because they are light years away. Which means they are how many ever light years new. Not arguing. Just saying.
There's a "CC"\subtitles button as well as the transcript if you have an issue understanding, if it's just that you have problems with accents. If it's an issue you have with understanding the actual content, then you need to educate yourself in more science subjects to do so.
I’m so thrilled that people exist like her to make observations of science ❤
Wow. She is clearly a talented science communicator. Great interview!
It's really great to listen to people that speak so passionately and confidently about their work.

brilliant interview with a brilliant prof who describes everything very clear.
Incredible interview! I never knew much about submillimeter astronomy, but this was highly informative! I hope Atlast gets funding
Great interview, Fraser!! I could listen to this woman talk all day
God, she's bloody bright! Anyway, thanks for the video. This channel is of exceptionally high quality.
I was expecting those images of proto planetary discs to have taken from space! Breathtakingly beautiful! Thank you 🙏😁
Great interviu!!! She explains so well! anyone understands! Thank you Fraser!
Impressive and interesting work that hopefully is going to be a reality soon.
Great interview 😃

After Aricebo, it's always good to see new observatories come online.
I hope this will get the required funding! Very exciting topic. Thank you Fraser!
Keep it up Fraser!
this interview was great!! never was into radio astronomy but this work seems so awesome lol
Great interview!
The open areas of those discs are probably where planets have formed. They clean out their orbits of material to build with.
nice interview, enjoyed this very much.

Awesome interview, amazing work being done
Universe Today produces ALMA favorite videos
Great interview & looking forward to more.
I love her,! So Instructive! Thanks!
Bless your heart Fraser.

Fraser: ".. so you are offering to find half of the matter in the universe"
Dr Cicone: "Or More." While smiling like the Cheshire Cat.
before this video I was down a RUclips rabbit hole, finding myself contemplating the doom of humanity due to our seemingly innate ignorance, but after finding this, I feel better, thank you.
Naw bro, we’re still doomed.
@@genehenson8851 I still find hope!
20 micron surface accuracy over a 50m dish will be challenging!
As she indicated though, the finished dish will be supplemented by an ultra high resolution scan of the surface of the dish so that software lensing can compensate for any anomalies.
@@MarinCipollina Wonder if that would work on the 100m GBT

The secondary antenna/mirror looks like it's almost 10 meters. Hope they build that beast.

Stuff like this is the only thing giving me hope AI won't replace humans any time soon. AI produces mediocre content even when it's correct content.

I always wonder how long scientists take to make their project's acronym spell out a viable word, or even a satisfying word.
Would a solar sail continue accelarating even after crossing the heliosphere?
How far can photons travel ?
How are we able to get such well defined images? With the shenanigans that we have to do to detect extrasolar planets, I'd have thought such planetary discs would've just appeared as a bright blob of light.
So wot is the nature of these planetary systems at the minute?
Talk idea: Interferometer software filters. LIGO uses them and so does the VLA right?
Is the accuracy of the dimension achieved with micro pistons behind the skin of the reflective surface?
I don't think that system needs to be used on these type of telescopes
Alma is also a great little city in Quebec, Canada. I know, I grew up there.
I've been wondering why your were kinds weird lol couldn't help myself

Strange, but true. Claudia is a cousin of, an even more famous Cicone... let me see..Ah! 'Madonna'.
