I agree! I would love to get a better understanding of the major space and ground telescopes. Where are they? What are their strengths? What are they being used for?
The JWST had me hyped up so much, I'm very excited for other advanced telescopes. Your videos are always a boost of motivation for me to keep studying harder❤️
I was all hyped up too. Then the whole Lou Elizondo thing happened and they fed us some false garbage shit to make us think while all the guys coming out and talking about these things say "this is the least compelling evidence that we have, there is evidence they won't release yet that would erase doubt from peoples minds". So, that makes me think, even if they do find something that would be world changing, they'd never tell us. Well just get the dumbass guessed images.
@@esecallum Well, the secondary mirror is mostly flat, not spherical. So unless light starts taking curved paths, we should be O.K. there. (i.e. light reflects off mirrors the same angle it hits them. So only the light reflected from the _primary_ mirror is of concern, since the other parts aren't in alignment).
I just wanted to say thank you to Dr Becky. You have inspired me in more ways than you could ever imagine and thanks to you I discovered a subject that I never thought I would love so dearly. I’m currently starting my first year of astrophysics in uni!!! So…thank you ✨
@@godsbeautifulflatearth why are there different sets of stars visible in europe than in south america on the same night? if you can't explain that, your "theory" about the world is shit. watch a ship sail away one time asshat :)
I wasn’t aware of these other exciting projects. I appreciate you bringing attention to them. Thanks to you, I’ve started watching astronomy/astrophysics videos all day long when I ought to be working. 😂✨
As a retired architect, I really appreciate your enthusiasm and excitement in your professional dedication. It gives me a boost just to watch your videos! Thank you!
More than 70% of the observations are made in Chile. I remember reading that nearly 90% of the photographs used in astronomy papers were took from Chile’s observatories
Been watching your videos for a long time now. I’m a graphic designer but I always say that I’m more a frustrated astronomer since my passion for physics and space is huge since I was just a kid. Thanks for your videos and explanations and the passion you put on them I can feel it in your beautiful eyes and body language! 😝. Keep it up! Next 10 years are going to be so exiting!
Thanks Dr Becky for such fantastic information, specially about the new telescope projects in progress, their locations and expected operational times. Since I am not a anywhere close to astronomy/astrophysics, I am literally a layman in this subject. I love the way you dumb it down to a level where it is possible for people like us to understand and helps develop our interest. A huge thanks to you for this. Being a Dr, this may not be easy. But for the greater good of humanity, you are a blessing. Thanks again.
With regard to JWST, and the number of years it took to build it, I always think how much of its design and components had to be updated/redesigned/replaced with progress in technology over these years. But I never heard about it. 🤔
I really appreciate that you said "rightly so". I really appreciate that. 🙏 Building on indigenous peoples land should only ever be done with indigenous peoples permission.
Dr Becky, I have such conflicting emotions when I watch your passion of your chosen work. When I was a kid (8), I had that kind of passion for space. So much that my parents helped me start a ceramic business so I could buy my first telescope. Which in the 70's where NOT cheep. Sometimes it gets to me, that the telescope that I had as a kid. That had cost me 2000.00 bucks. I can replace these days with a better telescope for a mere 300 or 400 dollars. It simply thrills me you are out there, on a medium that is accessible by any kid that has access to the internet. I hope your passion stays strong, and your message remains clear for the decades to come.
Doc, first, greetings from Raeford NC, USA. It is so wonderful to see how much excitement that you have for astrophysics. You put the information that you talk about in such a way that even a pipe welder ( like myself) can understand. Thank you. Wishing you and your colleagues nothing but the best. 🤙🏻🤙🏻
I’m so hyped up for the JWT’s first images, it should be absolutely fascinating. I must say the footage of the close up sun observations are superb. The sheer detail is amazing.
Yes, I had to pause the video on that sun spot and just check out the amazing detail and similarities to terrestrial phenomena. Fractals, fractals everywhere.
Thanks, Dr. Becky - that was super interesting! No doubt you'll keep us all informed of the progress of these projects. Looking forward to your future content. 😊
I did a presentation about adaptive optics in 1990 at the astronomical department in Münster, Germany. I am so glad that this technique is widely used now.
Yes, we are. But, unfortunately, there seem to be people who won't accept the truths/facts we will find out. If you are someone who thinks the Earth is flat inspite of all the evidence to the contrary or you are someone who thinks the moon landing was faked, you're essentially lost.
@@yvonneplant9434 this problem is more or less limited to "Murica" Where I come from (Iceland 🇮🇸) and live (Norway 🇸🇯) science denialism is not something you can be proud of. Maybe 🤔 it has something to do with the education system?
I understand the Hawaiian people protesting but on the other side, building a telescope to better understand our universe is probably the single best use of sacred ground I could think of. They are actual celestial looking glasses to the heavens.
Agreed 100%. This is the traditional use for mountain tops, going back thousands of years (looking at the sky). Telescopes are relatively small (even the largest ones), and non-polluting/ non-destructive. Let's save the protesting for chemical and oil dumps in the rainforest and elsewhere.
Space telescopes?,-yes. Ground telescopes? -no, more the merrier. Space telescopes take 3x as long to develop as their service life (20 years for JWST for 5 years of service), cost a fortune, and aren't serviceable. Too high risk. If only we didn't have "starlink"pollution... Ugh. Just when we're getting our best telescopes on-line, some greedy SOB ruins it for everybody.
@@erkinalp Unfortunately, the design expectancy is only 5 1/2 years. In practice, it could last 10 years. But this won't be like Hubble, which was serviced and extended. No capabilities of flying humans out past the Moon currently exist, and none will within 5 years either. The orbit of Lagrangian point 2 is not stable. It is a saddle point, with the telescope constantly wanting to fall in towards the Sun, and out towards Mars. In addition, it wants to bounce ahead and behind its orbit due to accelerations. As a result, it requires a powered (perpendicular) circular orbit around the L2 point. Fortunately, there was less fuel needed due to the A5 rocket being so successful, and so precise- but this is still a one-tank fuel operation, no refueling possible. When the fuel is gone, the mission is over. Of course, that's the best case scenario if everything is nominal. Space is a harsh environment. Rarely do any satellites function to full design standards. Things go wrong: a reaction wheel here, a sensor there, a circuit, etc. JWST has about 340 things that can go wrong at any time, most all are critical components. JWST is about the most complicated thing in orbit, and you know what they say about complexity. In practice, if we get 5 years out of JWST, it will exceed most veteran aerospace engineers' expectations. That's at a cost of *$2 BILLION dollars per year,* so ground based really is the way to go for wavelengths that can pass through Earth atmosphere. (UV and IR being the practical use for space scopes). JWST is a great endeavour, don't get me wrong- but there isn't exactly a bottomless pool of science funding available. $2 billion per year (or even $1 billion/year if it does somehow last 10 years) is a very large bite out of our community's budget.
We are at a potential turning point right now, if StarShip become a reality or something like it, everything changes big time! It the equivalent of an aristocrat astronomer back garden Observatory from the 1800-1900 that no longer has a clear view of sky's thanks to those new street lights that's been installed for safety in the city, and forced to move his Observatory to a remote area. Will the human race spend eternity window shopping or actually go into the store and buy something? As impressive as these ground based telescope's🔭 are can't help but think that they are the last of there kind like SLS rocket 🚀. The future is a constellation of large multi-purpose satellite platforms for the solar system to. Observation. 🔭📡 Communication. 📠📻 Navigation. 🗺️ Etc.
@@drmosfet Hubble already has to throw out 8% of its images because of "starlink" satellites passing over the telescope. NASA projects that will rise to over 20% after completion of the "starlink" launches. Plus there's all the degradation to Earth observation satellites, climate, weather, etc. (Earth is a planet too, worth studying). If "starship" is completed, it will signal the end of "the Golden Age of Astronomy", which we are currently enjoying. ("Starship" was designed to dump huge volumes of constellation satellites into orbit, despite what emperor elon tells y'all- hence the bay doors and no Launch Abort Systems). Plus, there's the pesky problem of collisions China lodged a complaint with the U.S. after its space station was almost hit by 2 different "starlink" satellites, a near miss with Oneweb, plus there's Kessler Syndrome, etc. If only these rockets were going to be used for *good,* instead of personal greed in a telecommunications takeover. (Amazon and Oneweb are also existential threats to astronomy and space access, not just "starlink".) If we could only keep our orbit clean and available, great science could be done there. Unfortunately, our atmosphere has been "privatized" by financial greed. I fully agree with you about light pollution. Unfortunately, "starlink", Oneweb, and Amazon will increase skyglow by 30%, making even naked-eye observing a thing of the past. You'll look up and see *orange,* not a dark sky with bright stars and familiar constellations. And unlike ground-based light pollution, it won't matter how far away from city lights you drive. JWST is far enough out away from Earth that "starlink" shouldn't be a problem, but any telescope that can be serviced and maintained (i.e. more than a 5-10 year lifespan) will be degraded by "starlink", including space telescopes like Hubble ST, and radio telescopes ("starlink" puts out K+Ka band radar interference). Enjoy it while you can, that's probably all we can do at this point. JWST should be amazing, if all goes well.
Super exciting times. I'm hoping someone can find a cure for old age so I'll be able to stick around into the second half of the century. So much potential to uncover more wonders of the universe.
@@Alexandruthewolf Even with all that, living to 100 requires a lot of luck. My wife was obsessed with healthy living; now she is fighting lung cancer at 67.
@@franklittle8124 I'm sorry to hear that Frank. Best wishes to you and your wife. A friend of mine has a very strict dietary regime and several years back had to have an op on a cancerous kidney. He asked the specialist about this issue, and was told it is pot luck. One can only try to mitigate the possibility, but there is no guarantee of exemption.
I love the way Dr. Becky dances around saying "size matters." I'm so excited to see the science that comes from JWST. I'm curious if any of these telescopes have applications to Dr. Becky's research and whether she has applied for any time on them..... Love these videos!!!
@@michaelsommers2356 That's a pity. The Dominion Astrophysical Observatory near where I live in Victoria still does useful work. It's only 72 inches (182 cm).
Sad that KAGRA didn't make the list (presumably because it's not teeeccchnically a "telescope"). I'm particularly excited about the new laser interferometer in Japan. Along with LIGO and VIRGO, the KAGRA observatory will help increase accuracy and sensitivity for gravitational waves, and I think that's really exciting.
I love these updates about telescopes. We know so little about space and these telescopes and astronomers like you will offer up loads of exciting discoveries.
Holy telescope! i did not know about the solar telescope. seeing the first picture with the US as scale blows my head! And Becky thanks for all the great content you put out! Got my first telescope last year and because of your night sky news updates i have seen some very cool things!........well if the weather is good....I mean i live in The Netherlands.....almost the same shitty weather as in the UK. But thanks for everything!!!
Just wanted to say you're awesome! I love your channel, I learn so much. Astronomy amazes me, space in general does too. I'd love to somehow work within astronomy somehow.
Dr. Becky: Much love to your program from Canada! I hope someday, that instead of constantly building new telescopes from scratch, governments can more efficiently use their resources and construct a gigantic telescope with modular mirror units that can be added on over time as the budget allows to increase its light capturing capability. And perhaps, to even take advantage of natural concave formations like a large meteorite impact crater to house such a construction, like the 300 km wide Vredefort Crater in South Africa. Its secondary mirror may have to be a large hovering drone or some unit carried by a self stabilizing helium zeppelin held in place by cables or gyro-controlled propellers. Imagine the optical images humankind will receive from a 10 km wide mirror that can be continuously expanded upon as extra modular sections become available. Getting away from this topic…I love every one of your episodes, but strangely my favourite episode is the famous “we’ve finally detected X-rays from Uranus.” You were showing a tell-tale smirk in the thumbnail…and I am I think, secretly a vulgar person. Another thing I’d wish for is a space observatory…a really big one, that can be constructed and attached to a future space station so that space based optical telescopes no longer have to be remotely operated, but be actually used and maintained by real human astronomers who are also astronauts.Finally, I am always amazed at how names are assigned to new telescope projects…some form acronyms like the “Atacama Pathfinder Experiment (APEX),” and one near my residence, the “Large Aperture Mirror Array (LAMA),” which is 66 liquid mercury mirrors, each 6.15 metres in diameter. Put together will yield images equivalent to a Newtonian telescope with a 55 metre diameter mirror. This is the brainchild of Paul Hickson of the University of British Columbia (UBC) whose first liquid mercury telescope was the “Large Zenith Telescope (LZT),” and his second 8 metre liquid mirror project, the “Advanced Liquid-mirror Probe for Astrophysics, Cosmology, and Asteroids (ALPACA).” I detect a trend in the acronyms here…as alpacas and llamas are very similar animals from South America. I had always wickedly hoped that someday, a committee of peers will get together and formally dedicate another new telescope to some pioneer and the resulting acronym will not be noticed until the observatory is complete and they realize in horror that their brand new “Stephen Hawking Interstellar Telescope (S.H.I.T.),” is not what they had planned for. ❤️ Diane, Vancouver, Canada.

In general, a lot of the cost for a large project can be regulatory, mobilization, cleanup, and demobilization. I think this is especially true for telescopes, ones going in remote locations. If you have the political willpower to get a telescope made, it makes more sense to make it as large as you can at once. Most telescopes, as you can see in this video, come in buildings, and those buildings are only as large as they need to be. If you made a larger building, you would also make a larger telescope to go in it. PS: Paragraphs would help someone parse your giant wall of text.
@@kindlin My apologies…it’s just that I comment for fun. It’s not a formal submission. My formal discipline is International Politics. I just happen to be walking in one door of the observatory and exiting out another. -Much love, Kindlin….Diane, Vancouver, Canada. SnFE13/22. 01:55 am
I love the new technology coming and I love your enthusiasm about it! Always make me want the process to go faster but know that what we have now is great too! 😁
I was fascinated with astronomy since about the 1st grade when I got ahold of a 5th grade science textbook, which focused on astronomy. This was about 1975. The telescope images that REALY got me hooked were that of the HST looking at Shoemaker Levy 9 crashing into Jupiter. Then of course the HST Deep Field and Ultra Deep Field were gobsmacking. Can't wait to see what JWST finds.
Hopefully TMT gets built, lots of people here in Hawaii oppose it but I think the research it would provide would be amazing. Glad you’re also informed on the situation as well!
I too hope TMT gets built, and I was dismayed to see the obstructing of TMT referred to with 'rightfully so'. TMT will be America's greatest telescope and will provide vital northern hemisphere coverage to compliment that of the Southern giants. A solid majority of the state voters have repeatedly stated in polls that are for it, clearly the relatively few protestors do not speak for 'The Hawaiian people'. It's a safe bet they don't even speak for all Native Hawaiians, as with any group of people there are bound to be varieties of opinions. A mob of activists should not pretend to speak for more than they do and must not impose their religious views on public policy. There are numerous students and astronomers there, of all nationalities, who would also like to help define Hawaii's future and they deserve as much of a chance to shape the destiny of their beautiful state as those who want to sweep the telescopes off Mauna Kea.
I'm curious to what extent the Euclid Space Telescope may shed light on the Hubble tension. For those who aren't familiar with the Hubble tension, there are multiple ways of measuring the expansion rate of the universe. By looking at the cosmic microwave background, you get 67-68 km/s/Mpc. If you use more local phenomena like type 1A supernovae, red giants, and so-called Cepheid variable stars (all of these are things we know the luminosity of and therefore can use as "standard candles" for measuring distances), you get a value more like 73 km/s/Mpc. While it may be easy to dismiss the problem as a measurement error, the error bars are decreasing on those measurements but the gap still remains. This is a mystery that I'm really impatient to see resolved one of these days.
Thanks for this. I got all excited with the JWST launch and approach to L2, but felt a letdown once it arrived. How sad that eventually, galaxies will be too far away to see at all.
Dr. Becky, what an enjoyable portrait of the array of new astronomical instruments coming online in our current golden age celestial exploration and understanding. I’ve been lucky to have a ring-side seat for the last 4 decades as my cousin is an optical engineer who’s first project after graduation was over a decade spent on the 10 meter McDonald observatory where their altitude/azimuth mount allowed them to build a telescope the equal size of the (then single) Keck for 1/10th the cost. Currently he’s in Chile working on the Vera C. Rubin survey telescope. His role has been for the pointing systems for both telescopes from design and construction through commissioning and initial operations. Many of the technologies employed at each have been the first implementations and have been key enablers of providing Astronomers & Physicists these massive new tools to increase humanity’s understanding of the Universe. What an exciting time to be alive seeing all of these take shape.
Ways we might detect warp drives or wormholes or space highways or space time bubbles. Is if Light comes out of nowhere . If star light skips over light years alone with any star ships
You'd think scientist would come up with cool names for their instruments, like the super mega photon sensor or something, yet we get the "Extremely large telescope", I guess its more descriptive then anything else. XD
Since most scientists probably over index on the autism spectrum, I'm not surprised. People on the autism spectrum are normally less inclined to the cool things, and more inclined to be pragmatic instead. I wouldn't be surprised if that were the case for the ELT etc
I love that you mentioned the GMT. I saw some of its mirrors being made when I visited the University of Arizona in 2019. The mirrors were hugh individually so I cannot wait to see them put together.
That's why good astronomers know how to write computer programs to do the analysis for them. They're already very used to taking old datasets and figuring out new ways to squeeze results out of them. They're still finding hundreds of new exoplanets out of the Kepler mission data even though the telescope was retired several years ago.
I remember some years ago I bought my youngest child a time machine** (aka Telescope) that weighs less than 20 lbs., and could fit into a large back pack, that you could take into wild, away from city lights, and use with computer aided navigation to view into the past. Thing is I seem to remember being told that that little telescope, by virtue of its design, was more powerful than the original Griffith Observatory in Southern California. (** For the curious it was an ETX90) In my long ago college days I remember friends taking Astronomy courses at the observatory, to try and navigate the sky, so they could seemingly find "bright dots" in their backyards (we're talking late '70s). Now when my kid go into the hills, hook his device to his phone and take incredible colour photos of sights that are automatically located. How far have we come in the last few decades? What's on the horizon for the next? As always thank you so very much for the video.
I wouldn't have known about the other huge and extremely exciting telescopes if I hadn't watched this video! Thank you again for another brilliant vid, Dr Becky! Telescopes (especially VERY huge ones) get me so hyped and I'm so glad to know that we have plans for even more gigantic scopes!!:)
I have been following the Vera C. Rubin (LSST) project for over a decade now and am eager to see if it can live up to its promises. I have had the honor of meeting a number of the key players in the process back in its early stages and their enthusiasm was infectious. When they held their annual meeting in our town, they were kind enough to give a series of presentations around town from talks in bars and taverns to more formal presentations in theaters and the local college. Much to everyone's surprise all the events were filled to capacity as the city had great enthusiasm for everything they had to present. (So much so that I was never able to attend a presentation myself as the venues were full each time I tried.) I think people very much underestimate the interest the general public has for astronomy and the esteem in which professionals in the field are held by them.
I should have picked up your book a few months ago when I had spotted it in the wild at Barnes & Noble because it wasn't in stock today when I went. Good news, that means somebody else bought the copy. So I ordered it from them today, and it'll be shipping to me soon. 🙂
I have read unique innovative concepts for future generation telescopes past the current next-gen ones like using a large crater of the moon on the far side as a radio observatory, a solar gravitational lens, and aragoscopes. Those look extremely ambitious. By the way, I'm looking forward to your discussion about the likely discovery of Proxima d. The system next door really is an exciting target for direct imagery of our upcoming observatories.
. OMG! those eyes can never get any larger! Such passion I have NEVER ever seen from anyone in my life! I do hope she ends up being one of the best scientists of my time! She certainly deserves it! . And along the way, I KNOW a lot of people are being inspired by her, and will bring a lot of change in their lives! 💖💖💖 .
Thank you so much for that, I didnt realise that operational satellites can interfere with this work. In other news. just received your book, 10 Things You Should Know! Super excited to get an update from what I learnt many years ago. Keep up the passion Becky! 10 out of 10 shooting stars.
One thing that the low frequency radio telescopes such as Lofar, Chime, SKA Low are able to do is to see the red shifted emission of hydrogen gas beyond what will be able to be seen with JWST. However they are limited to the region where the red shifted emission still penetrates the Earth's atmosphere.
Just watched this for the first time. Great to see the advances. Euclid is go! JWST doing amazing stuff. SKA I heard many talks about this doing my PhD in the 90s/00s, really keen to see what it can do imaging supernova remnants which was my main area. Then the Vera C. Rubin, this is going to rock asteriod research (pun intended), exciting times ahead!
Amazing video as always! There isn’t a day that goes by now that I don’t regret going into astrophysics. I’ve loved it for so long. Hope the job market crap gets better.
One nice thing about this Sun observing telescope in Maui, Hawaii, the DKIST, is that if it doesn't work or perform as expected, it can be used as the First Giant Solar Frying Pan in human history 🤪🥵
I recall reading an article about 10 years ago on the expected volume of data from the SKA being something like 100 times the volume of internet traffic!
Of the five telescopes that you cover in this video, I am most excited about the Vera C. Rubin observatory! I believe that it is going to give us a fundamentally new view of the sky whereas the other telescopes even though they will be much better than what we have now are really just enhancements to the view that we’ve had for a very long time, a very clear view of a very, very small patch of sky at one time.
Just...so...awesome. In regards to the Vera C. Rubin Observatory incoming data. One cannot comprehend the amount of storage needed for this task. And I wonder if this is where upcoming exascale computing comes in. It is the only thing I can think of that can process all of this. Sometimes technology really is friggin amazing!
