artemis photo looks amazing, it is stunning what the people in NASA are doing
Starsheild. Government and military communications. Built and marketed by a Private company. Wow!..you can't much more powerful and influential than that. Awesome space bite!
I love hearing about new telescopes, and then seeing what new telescopes can do! And yes, having competition and even multiple companies giving us multiple options for space travel is much better than only having one. We found that out multiple times. Maybe we finally learned that lesson?
It's very cool when we learn stuff that doesn't fit. That's where new science is born! I love it!
Yes, the crater on Mars is named after Frederick Pohl. And being Canadian, there is one situation you'd need to use imperial! That's at the local lumber store, if you buy something for a project like building a shelf. 😉
Yes it's bad to have all your eggs in the Starship basket because it's possible Starship could get delayed, but Starship is so far ahead of everyone else that it's hard to see how a delay could be big enough to allow them to catch up.
Well said , they did overachieve so they should be the first one to travel with a full crue 😊
All of the other "players" on the NASA list of bidders have a PROVEN history of being so far behind schedule that SpaceX could be ten times as slow as they have in the past and still win the race. I"m in favor of having competition but right now you have SpaceX and then everyone else. NASA did the right thing to give the first two landing projects to SpaceX.
Thanks for the news, Fraser! 😊
Stay safe there with your family! 🖖😊
Hey dude!
@@3000gtwelder Hey man! 😃
How's everything?
Your conversation on into the impossible with Brian Keating was awesome. It’s because people like you exist. So many of us have gained a deep insight and understand our universe far better than we could have ever dreamed of.
Thank you 🤓💚♾️
Thanks Fraser, for all your output.
I would love to know more about the advantages/disadvantages of large arrays of radio telescopes vs single very large telescopes like Arecibo. Have you discussed this before?
Uh... Google it? Do you think this is the only place to get that information?
With a phased array antenna, you can point the main beam anywhere within the element pattern. I assume the "Christmas trees" are pretty omnidirectional. If you recorded the output from all of them, you could use the recorded data to point anywhere.
On the first story of the day, are they going to build a radio telescope like that on the Northern Hemisphere? Why are radio telescopes based on the southern hemisphere for the most part?
Love this channel. Thanks again.
leaving nothing open
is the best way to shut me down ;)
good episode
oh god, why would they choose 197 for the number of antenna?! 196 would have made a lovely 14 x 14 grid! gah!
7:50 Just gotta know that someone is asking if Laser light either in another part of the narrow transmission lobe or reflecting off a target satellite can be picked up by their nearby spy satellite.
Another great video thankz
There’s an app called ‘Solar Smash’ that lets you simulate asteroid impacts as well.
What if we somehow magically organised to meet sentient beings, that come from the unreachable universe, what if we meet them halfway? We could swap postcards, then probably be even more sad because we can't see their most beautiful scenery up close.
Pohl crater looks really pristine. It would seem that while at the time there was enough water for a huge tsunami on Mars, the water couldn't have lasted much longer or it would've eroded that crater much more. Was there anything in the paper on that?
Here's the paper: www.nature.com/articles/s41598-022-18082-2
Omouamoa as a metal asteroid was kind of terrify at the power it would have had, that thing was really trucking! It was plugged into an Earth impact simulator on a livestream using a modest size, metal and... well, don't both with close to solar system speeds if you want to know (as solar shystem speed would do a decent amount and were such in the solar system, just not considered a huge streat), as when something like that can go blazing through at stupid speeds by comparison... ...the damage was enough to have a moment of silence as everyone absorbed what such a monster would have done...😵
Speed is King.
I'm watching your latest collab with the magnificent John Michael Godier, and you guys just triggered a question for me - How come none of the upcoming new space telescope plans (like Carl Sagan) are even considering taking advantage of SpaceX innovation in their planning?
Regarding the "square kilometre array", would that had been able to detect if the "omoamoa" object actually had transmitted some kind of signals? Or detect if there was some electronic activity in it?
What if an asteroid hits the earth..? (zooms in on kreml, pure coicidence!)
Hey Fraser
good job again
how do u get all these information anyway ?
do u anyone in NASA?
Hi Fraser; love your show! QUESTION: Cost considerations aside then if you could modify the most powerful commercially available optical telescope on the market for space use and then launch it into space then would the enhanced view be worth it? Or to put it another way if someone offered to do this for you so that you could point it where you want when you want then would this idea appeal to you?
I think the radio "Christmas trees" look a bit pretty in a minimalist kind of way.
Yeah, it's a really clever idea for seeing longer radio waves.
How is interferometry done with antennas in two different bands?
When I looked at the date and saw it was the 12th, I swore mildly, under my breath. I was kinda looking forward to seeing the Orion recovery...
Then I remembered that the USA is a number of hours behind Australia and that even though it might be 4am here, on the 12th of December, it might not be too late to watch the recovery of the Orion capsule by NASA on the 11th of December. It was, though. I was 2 hours too late!! And while I can watch the stream that was shown live 2 hours ago, I think I'll go to bed, instead and watch it later.
The recovery happened, did you get a chance to see it!
@@frasercain
Indeed. After my old-man-nap, though, it was a good 6 hours after the fact.
21 centimetres ! Fraser's got some BIG hands ladies !
And no hair! Ooo-la-laaaa
Fascinating video as usual. So Ligos was shut down just at the right time to not make the observation of a rare gamma ray burst. Murphy's law got there first. Looking forward to the construction of the 1k sqr meter telescope. I think when we find the beginning of the universe we will find the end of the universe. This is based on my own home made theory of Space/time /event/ infinity. It has the great advantage of having no limit whatsoever yet contains all limits infinitely, If you think the universe is strange, try infinity. When physicists say nothing they don't mean nothing which must mean they mean something of some description, such as a quantum or electronic or/and plasma field. It would be helpful if physicists would get the terminology clear in this area. Otherwise they are saying nothing about everything. Thanking you for your in depth informative videos.
But when LIGO comes back online it'll be able to discover many more events. The most recent shutdown gave it the ability to detect a merger a week. The next improvement will detect several a week.
Hey Frasier - I've got a good question for this week's question show:
Let's say that one of these upcoming telescopes like SKAT successfully detects signals of intelligent life in our galaxy. How do you think the news would be delivered to the public and how might the world react?
The news would be delivered by astronomers writing research papers and arguing over the results. And with media like me reporting on the controversy.
Remember the "discovery" of life on Mars? It would be treated like that.
Nobody talks about my "Teeny-tiny Underwhelming Ridiculous Downfacing Telescope" aka TURD and I was only asking for $5 million. Military industrial complex crushes another brilliant idea.
I loved SKA in highschool!
I'm sure the scientists kept that acronym as an in-joke.
i got another question: can you use the 1km^2 array radio telescope to see distant planets and/or moons like pluto/eris/sedna/makemake etc with more than 1 pixel resolution? if not can you build a 1km^2 interferometer with optical telescopes and do that? or does that need a gigantic single telescope?
Planets don't generate a lot of radio waves unless they have a magnetosphere. So no, this won't be your telescope to see exoplanets.
@@frasercain but do you know what will other than space probes? a single giant telescope or a giant optical interferometer? or could you look at a planet for like 10 hour straight and use a supercomputer to reconstruct the image?
Is the kilometer array the explanation for the aura project in Alaska
So regarding asteroids hitting the Earth, one of the hardest ones to predict is asteroids coming in from inside the orbit of the Earth, because they are hard to see in the glare of the Sun, whereas the ones coming from outside the Earth orbit are aided by the glare of the Sun. Is there any spaceships planned to go to the L5 & L4 Lagrange points and observe the vicinity of the Earth from there to search for asteroids? There, I guess I worked in an asteroid and a Lagrange question into one!
That's a great idea, but humans have a tendency to not place importance on possible scenarios, we seem to prefer scurrying to "fix the systems" after disaster strikes. I'm picturing government bureaucrats calling a mission like you suggest a "waste of taxpayer money" when it's a brilliant idea and a necessary expenditure.
So in other words, can we say that the Square Kilometer Array is a replacement of the Arecibo Observatory Dish? In a way?
Sounds like it to me
Could it pick up our level of Radio and TV broadcasts from the elsewhere in the local galaxy?
Yes, about 100 light-years away.
@@frasercain cor blimey.
@@frasercain you keep answering my questions while I'm typing. I need to learn patience someday.
@vapormissile Me to. Usually I put a time stamp on when I got onto the tangent for the question.
FYI, the Milky way is ~50,000 light years in radius. It's not flat, but if we reshape galaxy into say a 20,000 light year radius sphere then we can calculate that we will only search 1/8,000,000 of it, using 100 light year scan radius. That's good to know, if we hear nothing there is 7,999,999 more volumes to search..
That's all nice and good, multiple systems for landing on the moon, but what good is it when that second provider takes so long to build it that SpaceX will have 16 starships finished and ready to go by the time that other company has built ONE. At least that is idea I get , looking at Blue Origin, SLS, etc etc, the list goes on.
If SpaceX leaps ahead by that much, it'll be tough to compete with them. But what's likely to happen is they succeed and then everyone copies them. Like what's happened with Tesla.
@@frasercain Agreed. At least I hope it goes that way.
Fredrick Pohl my favorite author (Gateway) ...
I hope that's who they named the crater after. :-)
"StarShield" is the most Tony Stark name ever...
Great vid and thank you. However, on the topic of metric vs imperial numbering systems that you brought up, it is always a wonder and a bit disappointing to me that many scientists (including astrophysicists) often work with immense numbers and calculations (sometimes to the 20th power cubed and beyond). Yet they are stymied by imperial numbers.
There isn't one spoken language on the planet, there are many. If you want to standardize, check out the International Civil Aviation Organization. Administratively, they recognize and work with several languages. However imperial number values are required to be used throughout the air traffic control system. You never hear an air traffic controller announce "British Airways flight 2702, climb and maintain 10668 meters." Instead you will hear "British Airways flight 2702, climb and maintain 35000 feet (or flight level 350)." There are differences in cultures and standards across the planet that we all have to learn to overcome. They Let's mix a dash of reality and maturity with the research shall we?
The metric system makes sense for scientific calculations because it's based on 10 rather than seemingly random points of reference, like the length of a medieval king's right foot. Scientists aren't stymied by the imperial system, their goal is efficiency, and the imperial system adds unnecessary complexity to a core element of their work. Metric is a time saver when working with immense numbers to the 20th power cubed and beyond.
However, I feel the same as you when it comes to everyday conversations & calculations. I was going to leave a snarky comment about how nice it was not to have metric shoved down my throat for once, but decided against it. Oops! I guess I just did.
When you're working with scientific calculations, metric is so much more efficient and easier to work with in your mind. I'm really fortunate that I learned everything in metric, and whenever I need to work with imperial units, it's all so unintuitive. Change is hard, but it's better in the long run. It's kind of like learning to touch type instead of hunt and peck.
@@frasercain There's a little "use metric" button below LAUNCH ASTEROID ;)
Why was the camera wobbling on the Artemis?
It gets windy up there.
Question, if a telescope has a really large aperture but only on one axis (like two square km arrays hundreds of kilometers apart, 1 km aperture on one axis and hundreds on a other) does the image end up blurrier on one axis than another?
...I understand this might assume both arrays made for the same frequency, though
My poor brain. Good question. This channel rocks.
And backup plans
@16:37 Are the degrees in °C or °F?
Unfortunately they're imperial, which means F degrees.
But it was probably a joke, since it's about angles. 😉
@@perpetualbystander4516 A religious friend of mine has repeatedly asked me to stop making the same joke about angels 😉
I am sure it's just pure coincidence but i find it ironic that our earth rise is largely dark this time round. Just when our world and resources are being dragged back into the insane darkness of war.
Just a coincidence.
4:20 half of square kilometer is not 500 square meters
It should have been 500,000
That's an error of significant magnitude. I'm coming up with 250,000 square meters. Please check my math. Maybe he meant 500 meters square.
@@georgespalding7640 He meant 500,000 square meters.
1 square kilometer = 1,000,000 square meters.
Hi Fraser,
I was watching videos of the first moon landing and I had couple of questions, one, more rhetorical/rant and another an actual/stupid question.
1)Why did the conspiracy theory of faked moon landing had _any_ traction - if the first mission that landed left something that _anyone_ could check - the reflectors?
b) seeing how "little" energy one needs to liftoff the moon - I had a question... Could one.. just convert/store some of the potential energy from landing in something a bit more sophisticated than a/but something like a "spring"... and when when you need to go back, you just "boing" yourself half-way back to space on your way home? (I might have spent too much time learning physics from looney toons though:)
You're asking why there are conspiracy theories? People who believe these things aren't convinced by evidence. It's generally confirmation bias for a worldview they already hold: that the government is hiding stuff and manipulating them.
The escape velocity from the Moon is still about 1.6 km/s which is faster than the fastest bullet. But a mass driver like Spinlaunch would be able to send payloads home. :-)
@@frasercain ah, so no "boing" type of tech on the moon then - what about asteroids?;)
Hi Fraser! Have you ever considered creating a Universe Today app?
You could just have a shortcut to the site on your desktop or on one of your phone screens, and be able to go to it any time - and Fraser wouldn't have to hire someone to build an app. 😉
Can they detect alien signal and frequency..
Sure, if they're close enough or directing a signal at us.
You got something wrong there. A square kilometer is a million square meters, so half of that is not 500 but 500000 square meters.
Yeah, verbal typo
This has me curious about these huge GRBs - they're almost always in galaxies over a billion light years away, therefore happened over a billion years ago - are they just rarer in the modern universe? Or is it just the fact that there are more object further out, so the sheer statistics of it are that further away are enough that point directly at us to see more often than closer?
Hydrogen atoms are tiny. How do they emit waves 21 cm long?
I'm excited about the square kilometer array; but, I doubt it finds any E.T's. There's no E.T.'s out there; otherwise, the Earth would have been vistited already.
I wouldn’t be so sure. We’ve only been at our present evolutionary level for about three hundred thousand years or so. (That’s not long) We’ve been looking to see if there’s anyone else for such a tiny amount of that time. This concept is in its infancy.
Give it time 😊
@@andyoates8392 the prediction of the Fermi paradox is saturation We're not looking for a needle in a haystack.
I also have to stress the Rare Earth hypothesis. I grew up reading the original Rare Earth Hypothesis book - Isaac Asimov's "Extraterrestrial Civilizations." Since that time, others have thought of the Rare Earth Hypothesis, and even more evidence suggests multicellular life is rare(not single cell which is probably quite common).
@@oker59 the possibility of us actually being alone is minuscule yet, so far. Yes. We seem to be alone.
We’ve only just started to take a closer look though. Have we been looking long enough, or close enough, or even in the right way?
@@andyoates8392 - how do something we never experience or observe exist?
Until now there is no indication of any aliens anywhere, so claims about their existence are pure speculation
When Oumuamua past by, I heard that extra Solar objects were meant to happen fairly often. Should we not have seen another by now?

1.6 km to 1 mile and 3.33333333 feet per metre if that helps any lol
And 1 inch is 25 mm or 2.5 cm
How many furlongs in a cubit?
@@frasercainHow the hell would I know?!?!? I would need to google Google that but as I'm not a horse racing fan and I'm not looking to build any pyramids in the near future i probably won't lol 😆 😅 😂
I'm starting to have negative thoughts about Starlink...
I mean, how many satellites are TOO many for a private company to hoist into orbit? If some Chinese corporation was putting 15,000 satellites into orbit and NONE of them would be of any use to anyone outside of China, I'm sure there'd be a lot of negative sentiment about such a project. Starlink isn't 15,000 satellites and it's technically available to anyone and everyone (who's willing and able to pay), but again, where does it end? When is it too many satellites? How many corporations are going to fill the sky with satellites?
Starlink is going to be 42,000 and you can assume there will be others. I'd guess there'll eventually be over 100,000 satellites. But you won't be able to see them. They're a big problem for astronomers, but not for regular people just looking at the sky.
“Short Gamma ray burst is caused by some kind of collision between exotic objects” classic Star Trek lingo 😍
Theories about how they

be proven. When they observe
something they cannot explain
proves it. Theories are theories.
Theories are theories which is why we do experiments. You do this every day in your life. You have a theory for why your car isn't working, so you try a bunch of experiments to get it going again.
16:35 Aren’t Canadians and Americans close enough to be comfortable with both systems? Lol
You'd think so, but nope. Only the nerds from both countries are somewhat comfortable.

I'm still concerned that SpaceX still doesn't even have a proven, reliable way of landing Starship yet, let alone everything else.
Well... to be fair, they're not done designing it, and haven't ever claimed to be.
Starshield...yes, let's put even more satellites in orbit. Soon all that will shine on our sky are satellites, not stars. Well, for telescopes, mostly.
4:38 For all our tax payer money, we get Gopro 4 tech in 1080P lol. Come on, they could have at least upgraded to the Session 5 🤣
If an asteroid hits my house, it is easy to calculate who would be vaporized. Which would really piss me off, Especially if I where in the middle of some important activity at the time, such as making love or drinking a beer🙂
Not the beer!
Still doesn't explain how we went to the moon in 1969. Specifically all of these new companies bidding on the tech to land on the moon. Something isn't adding up.
You got ‘‘em caught John. It’s almost like having an unlimited budget makes things more achievable.
