16:52 The switch to black & white for moments of thought are a great touch.
And the music stops 😂 😁
For Australians. Swinburn astronomer Alan Duffy stated earlier this month in timeout website, that the best way to find the nova in our sky is to "Look towards the north an hour after sunset; the constellation will reach its highest and most visible point at midnight. Stretch your arm outright towards the horizon, about a hand's width above the ground. Make sure to have no hills or buildings in the way."
Hope this helps any fellow Aussies out there 😁
I didn't realize you could see Corona Borealis from the south
Thats what i originally read, until i found the recent timeout publication. I'm not an astronomer so I'm putting a bit of faith that these guys know about what they are reporting. I did find a couple of independent sources, one an indigenous astronomy site that stated arcturus could be seen in september on the northern horizon. They seemed to lend some credibility to the timeout item.
Fingers crossed
@frasercain oops forgot to tag u in my thoughts. Its under my original posting. ❤
If it works for Oz it will work for us same here in South Africa 🇿🇦
It should get to about 30 degrees above the horizon.
I cannot wait to watch interview about air-breathing satellites!
Ewhaaaat? I'll be googling that. News to me.
Wonder how it will handle the random atmosphere expansions from the sun's activity.
Same can’t wait
I thought the satts would just briefly dip into the atmosphere to collect some air. Staying there seems more difficult. Lower altitude, higher orbital speed!
@@paulmuszynski5138 Nah It's probably not meant to be dipping down, it's staying at an altitude. Technically speaking if you're moving fast enough you can orbit the planet at sea level, you'll just have a ton friction and ... mountains in the way. The lower you orbit the faster you have to be moving forward, move faster along the curve of the planet than gravity can accelerate you down. Plus like was said in the video you get extra atmosphere drag which makes it even harder, you're having to fight both friction and gravity.
It does give me an idea though, what if we could transmit an energy source or apply force on it from the ground, you could make it much lighter because you don't need the equipment on the satellite itself, by like shooting a laser or microwave at it.
SpaceX switched to argon for the Hall-effect thrusters in 2023. You are correct that the older Starlink satellites used krypton.
What astrophysics get super excited about.. [A new star appears in the sky with similar brightness to every other star you see in the sky]
What regular people expect to see based on how excited all the astrophysics are [The end scene from the movie Angels & Demons]
15:40 Can't have Butch (Cassidy) without the Sunni Dance kid. 😆
It’s cool, I was reading a book from the 1880s and they specifically mentioned an outburst of T Corona Borealis
Tiny nova shmova, I want to see Betelgeuse explode!
I would be happy if they place a LIGO on the moon, the video with Dr Martin Elvis was epic, thank you.
Hey Fraser, I love your channel and what you do not just for astronmy journalism but journalism as a whole! Idea, a video on the top satellites scientist are using, what they do, and what they are doing now/in the future. You got me hooked to go see a satellite launch, and being a Floridian, I've not seen one....yet!
Thanks again for the Dr Martin Elvis interview, re: lunar based observatories. That was a fascinating and thought provoking conversation. I hope perhaps we can follow up on that.
Appreciate the tip on how to find the nova! Great work as always.
It might be possible to use an expendable starship to launch a 25 ton lander+rover+MAV setup straight to Mars. Even for a fully expended starship the cost would only be around 100 million USD. Not having to refuel starship in LEO means they could launch it much earlier. Probably the fastest, simplest way to do MSR.
Thanks for all the awesome work you do, you really brighten up my weeks with your journalism! Something I was wondering, maybe for the question show: how do we know Venus has had water levels similar to Earth in the past?
The solar system is becoming readily and easily accessible.
Starship: indeed
If all else fails, maybe we can ask the Chinese to deliver them for us?
That's a weirds statement to make given that Starship on its own is unable to get beyond LEO. Until cryogenic refuelling in space has been successfully demonstrated, I remain sceptical.
I might go check it out.
@@totalermist LOL and you will need 12-18 flights of other Starships to refuel it once! a recipe for failure!
We're already painting pictures of rockets doing interplanetary travel! - Blue Origin
I'll bet this new star will bring in newly inspired astronomers
One can only hope! 🤞
having even a single set of LIGO style gravity detection equipment on the moon would open up a huge range of discoveries and would help to massively increase the sensitivity of the whole array of LIGO style observations
Excellent update!
Danger also exists for COOL stars. Yes, they have a habitable zone, but it is very close to those stars. Even beyond the solar flare concern, any exoplanets that close will experience immense tidal forces. Presumably, those will lead to massive tectonic activity.
Why doesn't the nova destroy the other star when it goes off? How much larger would the nova need to be?
Was wondering the same thing!
Stars are dense as hell. It will take an enormous amount of force to destroy one
That interview was a great listen! Thanks for the Space Bites!
Fraser, it sounds like you're not familiar with the quick and easy way to find Arcturus.
Arc to Arcturus, then speed on to Spica.
Follow the arc of the handle of the big dipper and you get to Arcturus. You can then extend that in a straight line, and get to Spica.
Hah, I'm so used to seeing it.
Cool video, Bro.
Thank you for this presentation.
You covered several topics I think are noteworthy that I have not caught up with in a while. I'll be checking in from time to time.
Good stuff !!!
Nova will be 1,500 times brighter and you just need to go outside to see it. I don't know if anyone is sure yet, but just hearing it is interesting. A natural star glows like a 'Christmas tree' in the night sky!
With my luck, it'll be cloudy or storming and I won't be able to see it. Still mad the recent auroras that I didn't get to see because of weather.
18:10 Watched the interview and can confirm: a radio telescope on the (radio) dark side of the Moon could achieve some fascinating science goals. Also the other kinds of telescopy could be cool.
I loved it, it was such a cool interview, listened to it multiple times!
Is Boeings Starliner crew going to need rescue from the Space Station. If they do will the Starliner be sent back unmanned to an “safe crash” location? Southern pacific?
Excited for the air breathing ion engine interview!
👋 does that mean the perchlotates that are found in the Martian regolith that make it toxic for farming are NOT in the regolith at the poles? Since the moisture has to form on the surface and the evaporate, the moisture essentially should be cleansing the regolith....
When I took astronomy in high school, we were told to start with the Big Dipper, follow the handle out and "Arch to Arcturus." That's how you find Arcturus. From there you can "Speed on to Spica."
Thanks for these space bites ❤
11:15 - Cool sound.
"Air breathing ion engines" first thing I thought of was Stargate Universe and how the ship refuels itself by diving into certain resource rich suns
_"The expecation is that you only get that water ice forming near the poles ..."_
I guess you meant that one wouldn't expect water ice frost to form near the equator, but it sort of sounded like you meant that one wouldn't expect _any_ ice away from the poles -- which is of course totally wrong; there's a huge amount of water ice at mid latitudes, and some sulfate salt-insulated alpine glaciers (or at least one) near the equator, up by a recently discovered caldera complex
Lots of people still seem to think there's no water on Mars away from the poles, but that's absolutely not the case.
Thanks!
lights from the city is going to make seeing the nova hard
Anywhere you can see stars as bright as the North Star, Polaris, will be able to see the nova.
yea i live in Belgium its one of the worst countries for this it will probably be cloudy too maybe i should take a trip to north Africa or at least Spain for this .
@@belstar1128 Go to the Eifel National Park, Germany. It's a dark sky park, and literally on the border with Belgium. Granted, you're less likely to have bad weather in Spain or North Africa.
If you have a Seestar photographic telescope you'll be able to photograph Corona Borealis before and after the nova to spectacular effect, even from bright city locations. That's my plan!
@@RockinRobbins13 I like the sound of your plan !!!
you'd think they could send 30 ingenuity mars' helicopters with claws, a couple of communication base stations , all using 3 or 4 skycranes to land on mars via a falcon heavy for less than a billion. Then fly helicopters to retrieve samples with massive systems redundancy and all systems basically previously tested. I mean curiosity was ~4,000kg total and falcon heavy can send >10,000 kg to mars. helicopters weigh squat and comms stations similarly not heavy leaving return rocket less than half a rover itself.....
Of course the supernova will happen in my lucky horseshoe.. awesome, thanks for the info as always!
Nova.. sorry.. it does sound pretty super still..
"Bootes", as your software calls it, is actually spelt Boötes, with diacritics over the second o. This is because when there's a case of diaeresis, i. e. two consecutive vowels pronounced individually, the English language uses the aforementioned diacritics over the second vowel to show it is to be pronounced. E. g. naïve, Zoë, Chloë, Brontë and of course Boötes of bovine fame with two pronounced o's in it.
I got mentioned.
Fuel scoops Old technology it was first used in the space ships in Elite ! 👾
Nice vid, informative.
My buddies couldn't care less about astronomy 😢
Tbf, i live in the 2nd largest city of greece so light pollution is pretty bad.
But i bet you good money if i even try to explain to them where the supernova is, they will laugh at me thinking i am pulling their leg. In most people's minds the stars are so many and so random that a person like me (who is not an astronomer) couldn't possibly make heads and tails of them. Maybe a sailor but then again from 2 centuries ago!
That's a little bit depressing. I hope you find better friends, or at least a more fruitful location.
@@smeeself thank you ❤️
@sadderwhiskeymann No worries. I'm a sailor, so had to weigh in. 👍
I knew there is no way to know if a Super Nova was happening till it appears, but went back to learn that a regular Nova is 'common' and now see an example of why. Thanks for giving me the will to self educate.
A little math tells me there are 33 'nova' pulses travelling through space from this star to our planet that already exist and we are waiting on their appearance over the next 2,680 years if not another one ever happened.
Could those atmosphere skimming ion-thrusters also help heavier rockets save fuel on ascent by circularizing around that lower altitude and refueling with thin air to help boost to a higher altitude without having to carry that extra fuel from the start (maybe with various small boosts at the thin air perigee to raise the apogee over sever passes)? And how about installing some of those collector- thrusters on the ISS to assist with the recurring boosts?
Fascinating uoadte. Lots happining. Btw, Suni Williams name is pronounced 'Sunny', not Soony 😉
You know it probably takes about the same amount of propellant to go to Mars orbit and back as to get to a main belt asteroid. How much would it cost to make and launch a Dawn based space ferry to take a sample pickup lander to Mars and bring back the return capsule?
Summer 2024? So I will have to wait until December?
Apparently denizens of the Southern Hemisphere are unworthy of mention by Mr Cain, much less a reply
@@AndrewBlucher he is probably envious that we are some 4000 km out of 45 trillion km closer to Alpha Centauri.
Always enjoy your content. Is it possible to include southern hemisphere instructions to view celestial events as well as northern?
This one won't be visible from the south. But also, the constellations are universal whether you view them from the north or the south. We see the same Scorpio that you do, for example.
Air ion looks to have a major bang for dollar in that would build much more durable but in weight increase.
QUESTION: Fraser, you've been in charge of Earth's very first colony ship of a 1000 brave souls who are to brave interstellar space to hopefully reach their new home within 3-4 generations on the ship. Where do you send the Colony Ship and why there and which five of your previous guests would you choose to go on the ship? Thanks.
Wow, i've missed news about rogue planets. I thought they were more of prediction from planetary system models than observed phenomena.
I think there are literally thousands cataloged by now.
I think they predict that there's billions of them out there. To me that's one of the most fascinating discoveries of the last few years in astronomy. It just reeks of some sort of sci-fi fantasy story but it is apparently real.
Q. Will it ever be possible to somehow capture and confine a quantity of spacetime in a lab. Could we study it expanding?
I wonder how long a rogue planet could last if it started out as a vibrant life-filled planet like earth, but then got flung out into interstellar space. Like imagine they was a really advnaced civilization on it that could harness geothermal energy. I wonder how long they could last.
The Michelson-Morley experiment was not the only one that was
of concern to Einstein, however. In fact, since Einstein was well aware
of previous experiments with the same results, he probably would have
expected a negative result from Michelson-Morley. We suspect this to be
the case since interviews with Einstein show that he was more concerned
with the results of experiments performed about 10-50 years earlier.
Robert Shankland’s interview with Einstein reveals the details:
Prof. Einstein volunteered a rather strong statement that he had
been more influenced by the Fizeau experiment on the effect of
moving water on the speed of light, and by astronomical
aberration, especially Airy’s observations with a water-filled
telescope, than by the Michelson-Morley experiment.
Why would the “Fizeau experiment” and “especially Airy’s
observations with a water-filled telescope,” cause such consternation in
the mind of Einstein? Very simply, Armand Fizeau and George Biddell
Airy’s experiments are two of the foremost evidences of a motionless
Earth ever produced by man. Einstein’s contemporary, Hendrik
Lorentz , stated quite succinctly that these experiments put unbridled fear
into the science establishment. In remarking on those same experiments
Lorentz wrote this astounding admission: “Briefly, everything occurs as
if the Earth were at rest...”
Eventually, it would take the full force of Relativity theory and its attendant
Lorentzian-derived “transformation equations” to make even an attempt at
explaining the amazing results of Fizeau, Airy and various stellar aberration
experiments.
The Michelson-Morley experiment was merely a desperate effort, using more
sophisticated equipment, to overturn Fizeau and Airy’s findings, but as
noted above, it failed to do so.
Einstein’s biographer probably didn’t even know this history
when he wrote that, after the Michelson-Morley experiment, men were
faced with the possibility of “scuttling the whole Copernican theory.”
Unlike Einstein, most such biographers have fixated on the cart but were
rather oblivious to the horse. All in all, we can say this much for
Einstein: although his theories were certainly fantastic to the point of
absurdity, at least he was smart enough to know from whence his
opposition came. In the battle for the cosmos, the unexpected results of
the Fizeau and Airy experiments had already put modern science on trial,
but since they both produced anti-Copernican results, the clarion call to
the courtroom was not being trumpeted to the rest of the world. For the
rest of his career Einstein would do everything in his power to stop it
from sounding. As van der Kamp has stated: “Yes, I think I understand
the sentiment motivating him. If we cannot prove what we a priori
‘know’ to be true [a moving Earth], then we have to find a reason why
such a proof eludes us .” And thus was born the theory of Relativity.
All claims that the Earth is moving based on stellar aberration are presumptuous,
since from Airy’s experiment it has been proven that the necessity of tilting
a telescope to catch all of a star’s light is due to a fixed Earth in a moving star system,
not a moving Earth in a fixed star system.
Interestingly enough, the type of experiment Airy performed was suggested more than a
century earlier in 1766 by Josip Ruder Boškovic (1711-1787), a Jesuit
astronomer, and again by Fresnel in 1818, which may have been the source of Airy’s
idea. In 1746 Boškovic published a study on the elliptical orbits of the planets based
on the Copernican system (De Determinanda Orbita Planeta ope catoptrica, Rome
1749). He published a second edition in 1785 ( Opera Pertinentia ad Opticam et
Astronomiam, Bassan, 1785). Perhaps if Boškovic had had the good fortune to
perform an Airy-type experiment, he might have thought twice about adopting the
Copernican system.
When one reads Einstein’s works there appears to be no
ostensible concern that these experiments could “scuttle the whole
Copernican theory,” nevertheless, there is an undercurrent in his writings
that he is indeed cognizant of such implications yet does his best not to
alarm the world.
Relativity theory, by its very nature, is especially susceptible to
anti-Copemican interpretations, since for everything that Relativity
claims for itself in the way of a moving Earth in a fixed universe can
easily be “relativized” for a fixed Earth in a rotating universe. In fact,
stellar aberration was indeed a major concern of Einstein’s for that very
reason, since Relativity theory, in principle, demands equal viability for
both of the aforementioned perspectives. 492 Einstein’s concern was
justified. As we will see, Airy’s experiment threw a wrench into the
reciprocity of Relativity, for it demonstrated that it really does make a
difference whether the Earth is moving or at rest in regards to how light
from a star travels through a telescope mounted on the Earth.
Consequently, Einstein could not “relativize” the results of Airy’s
experiment, since stellar aberration provided a distinstion he could not
readily overcome. Consequently, Einstein would be forced to resort to
the ad hoc “field transformation” equations of Henrick Lorentz to answer
Airy’s results; and although others didn’t voice their opinions too loudly
for fear of being ostracized, everyone knew that Einstein’s efforts were
just mathematical fudge factors. There was one inescapable fact that
Airy’s telescope was revealing: barring any mathematical fudging, Earth
was standing still and the stars were revolving around it, not vice-versa.
😅
Cool 😎 stuff 👍
With regard to habitable zones: Are they based on earths atmospheric pressure? Could planets with denser atmospheres be further from the parent star and still be habitable/ have liquid water?
Or puffy thick atmospheres on planets that are younger but smaller than Earth.
I was taught that habitable zones were about the distance a planet's orbit was from its host star, based on the type of star. Our Earth is 'in the zone', and so is our Moon, but you can't live on the Moon as we do on Earth.
@@thomasboese3793 I'd say as a practical matter the habitable zone will be different for planets of different sizes and atmospheres relative to each other with other variable being the star. Age is going to be an issue on all these variables. It is suspected both Mars and Venus in the first billion years or so my have been inhabitable for at least microorganisms.
While Peelon is building towns, somebody else will be getting all the Martian Gold from Olympus Mons.
I use Sky Guide on my iPhone to find celestial bodies. Highly recommended.
I have tried to find an answer but I have have not been successful. Why is this star undergoing a re-current nova instead of accumulating enough matter to undergo a type-1a supernova? Will this nova cycle break eventually, and lead to a real supernova?
frost on olympus mons is so exciting
get yor news get or cold news here, lol
@@alexisdespland4939 huh??? 😨😨😨
@@tygical you have never heard or read the famous statement of curb side newsellers get you hot news here.
I see a problem with the air breathing ion engines. When we have solar flare events, the atmosphere "puffs up". If you are running a satellite at those levels and the atmosphere puffs up, seems like you would lose the satellite to drag.
I understand your point of view.
What I envision is, as the atmosphere 'puffs up', as you put it, the ion engines would have more 'fuel' to work with. A denser input would give you more output thrust. Is there just a single level of atmosphere pressure this ion engine can work in, or is there a wide range? As with any engine dealing with a drag, you need to explore the working envelope and plan to stay within limits. This would be an interesting project to research.
@@thomasboese3793 turns out Fraser Cain has a new video just released today that I am coincidentally watchin right now interviewing an engineer of that engine and they talk about this issue. The answer given was basically, "we are aware of the problem and working on solutions". There was talk about keeping a small tank of xenon on board to assist with pre-emptive orbit raising. The guy he is interviewing didn't really give the impression that this was a solved problem. He spoke of "reactionary" maneuvers meaning that without on board xenon, they would need to wait until the atmosphere had already "puffed up" to raise the orbit. But obviously if it "puffs up" too quickly, you lose the satellite. And then there are potential issues of your satellite having a variable orbit which depending on the application can be a problem.
for the air breathing ion engines, do they have to throw it out the back faster than the speed the air hits the intake?
My son and I were watching a Kurzgesagt video saying that while we can't make a space elevator, we could have spinning tethers that could catch space craft in low orbit and accelerate them into higher orbit, or even to escape velocity. They would be powered by decelerating vessels coming back to earth by catching them at high speed and slowing them down to lower their orbit. Is this actually feasible?
I'd think cool as a pull it out of hat plan would be to send a starship with a Dragon capsule with extra fuel in the cabin for getting off mars. A couple of Optimus robots to jump out and retrieve the samples....
Space bites!
cool im a new sub ! if i lived out in the country yup
Summer has already passed my friend. Its winter now.
Dude. You live on a globe.
@@smeeselfI think you are missing the point.
@AndrewBlucher Do enlighten me please, as I did, in fact, fail to see the point.
Cheers.
@@smeeself Hi Smee. Frazer mentioned the expected Nova, saying that it would occur in Summer of 2024. Azil was indirectly pointing out that in the Southern Hemisphere it's winter; summer finished months ago. I'd add that if we believe Frazer and wait for next summer then we would miss the Nova. It's a case of hemisphere discrimination, and very unscientific since, as you say, the Earth is a sphere.
Kind regards, Andy
@AndrewBlucher Ah, I see, I didn't detect the sarcasm in the answer. Thanks.
It's good we're all on the same planet now. Cheers. 👍
Hey Fraser, have you covered Iodine ion engines? They have advantages include dense, solid fuel.
No, I'll look into it.
Great episode, Fraser. Keep em coming.😁
Any chance we'll get a 1A instead of a nova?
I'm going camping in northern Ontario next weekend I hope the nova somehow happens sometime by then 😅
If your astronauts are celebrating actually making the trip, maybe it's not a good idea to continue to use that transportation device
Just found your site and podcast. I have a kind of dumb question. Could the asteroid belt actually be a planet that somehow got destroyed?
Will James Webb observe the TCrB Nova? I saw a proposal for it, wasn't sure if it got picked up
Fraser: Ror soil samples it's probable best/easiest to wait for a big dust storm and swoop down for a sample. No landing necessary. Right?
That's been proposed as another way to collect samples. You'd also get useful atmospheric samples.
@Fraser Cain
Can you dip a little deeper into why that Star pair is doing what it is to make the Nova. Why is that Nova doing a Nova?
When a white dwarf reaches a certain mass that undergoes Fusion and either it will do this repeatedly throughout its life or it will detonate completely
I can see we're about the Starship now. Good, at the very least Fraser will get more views. Banzai!
For the asteroid collisions at 15:17 why are the collisions labeled at the peaks on the red line? Wouldn't the amount of dust only increase once they had already collided?
What program are you using at 2:26 ?
Did something like this happen about 2020 some odd years ago ?
Astonauts- like the rest of us- "No way am I flying Boeing."
And then Starship will use it's soon to be announced transporter to beam the samples back to earth! Elon "is confident" they can do this in two years max
@frasercain Hey Fraser, I love your channel. I work at the new Snow King Observatory in Jackson, Wyoming, and we're all itching to point the 1-meter telescope at T Coronae Borealis when the nova happens.
Gravitational mystery - Between the earth and moon there is a point where earths gravity and the moons cancels out.
Riding in an elevator to the center of the earth, gravity would cancel out there too, at least that caused by earths mass.
So extrapolate to a collapsing star on its way to becoming a black hole. As it collapses the the center, ideally, would
not have a gravitational component due to being surrounded equally by mass. The geometry might be a hollow sphere with
the surface being "infinitely" thin. Within this sphere where no gravity exists, time would stop. Going from
outside the sphere where the gravitational potential is massive to inside where G=0 represents a discontinuity!
Why is this never discussed in black hole conversation?
Anyone else concerned about contamination from martian lifeforms? At least the Martian meteors that people have found on earth had go through an explosive ejection, vaccum and (surface) heating filter before landing on earth.
Maybe just send some a good set of robotic microscopes finally? I know the previous technical pushbacks on bringing actual microbial lab equipment. But compare that complexity and cost to a return mission. Definitely cheaper and quicker than returning mass from Mars.
13:45 the people making the ion thrusted aircraft should be in on this... Was it MIT, Stanford, it Berkeley....
Anyone know what App/Software Frasier used to show the location of the Nova? Looks very familiar but I've got about 10 similar apps on my phone and a few on my laptop, no idea which one it is.
Is there any chance someone will be trying to record a video of it happening? Or just pictures?
Some can be seen in the Daytime?
If we have hundreds or thousands of satellites skimming the atmosphere to "breathe" in their propellant, wouldn't this create a lot of turbulence in the upper atmosphere making it easier to gradually lose atmosphere over time? Has anyone (besides corporations) thought about the long term consequences of this practice?
Off road electric motorcycle could be a good way to retrace the rovers path for Mars astronauts, their suits could be skin tight instead of giant football bladders like the moon suits, the atmosphere would not inflate it as much as a total vacuum.
Q: could we design connectors to satellites and connect them post-launch so that we can keep congestion lower in the future? Ones that can share orbits?
You'd think Boeing would've lost any credibility or foothold in the space industry after the debacle with it's 737
How about sending the Lab to mars and get the samples studied on site. No need to return (half the cost) And then there is a lab on mars, for future studies.
What if time itself is tangled? Toward the end of the universe time starts to go backward then forward again. Who knows how many times we have been here doing the exact same thing.
how dark a location do you need to be in to seee the nova how long will it be exploding.
Hello Fraser I am looking to purchase some binoculars for my little girl for us both too use and I remember you have mentioned a particular one for viewing everything space related at least a beginner one ….do u remember what it’s called cos for the life of me I can’t find which video it’s linked in thx man we both love watching your content
Well, guess I'll be following the landing tomorrow then.
Edit: looks like June 22nd now.
Fraser, I'm in Oxford - like you on the island, we have clouds - unless it lasts for about 3 months it is unlikely we get a clear enough sky until November/December for a clear sky :(
How much of the CMB represents the universe that is visible to us today? Are they the same? Or has much of the area of the universe represented by the CMB expanded beyond our cosmic horizon? If so, how much?
