I would like to thank all of the people who donate and keep channels like this one running. I am disabled and on a fixed income and would love to donate but I cant afford to. I truly love this channel and respect all the work that goes into it every day. Thank You and God Bless you all
Doing what you can (which includes making sure you have the spoons for it) is all any reasonable person could hope for. I've been broke for a while, so just telling people about this great channel has been it. That's about to change, though
I know exactly how it is. I'm in the same boat. 🫶
I've been watching your videos for years and you are one of my favourites; your enthusiasm has not dimmed since I first watched you.
My wife and I got married in Lapland, Finland, and saw NO auroras. In 2015 I took her to Iceland for our anniversary, saw NO auroras (after spending 3 hours on a coach chasing them). We then took our children to Lapland in 2016, and again saw NO auroras. Last year sat in our house in Chester, England we see on the news that people as far south as Cambridge were seeing aurora, but we didn't as it was too cloudy. One day Fraser, one day.... I will see them!
WASP-121 b also has the official name Tylos, as it was named by the IAU (you can also see this in the image you showed for the planet at 4:13, where it says the name)
In 2023 a bunch of exoplanets got new names, including Tylos, because they were all prime targets for JWST. I think its pretty cool how we're giving some of the planets JWST is going to study official names
My *unneeded ksp comment*
Planet Tyler 😂
@@FleshWizard69420 better than wasp-121 b lmao
You've been doing this for years and I'm just amazed that you're (still) so excited about all this new knowledge ❤️ love the vibe and thank you for everything you do ❤️
Frasier, I've been watching your content off and on for about a year, and it's the best thing going. I'm usually left speechless at the beauty up there. Thank you so much for all the time and effort that you put into it. ❤ much love
They can't get this thing to orbit but its awesome that they have a working metal cage on cables 🙄
The more I look at starship, the more absurd it seems as a lunar lander.
My favorite aspect about ancient astrology and astronomy is about what it actually means to us on a civilization level
The star maps are really interesting. There's this indescribable mix of emotions that come from a mystery like this. We'll never know for sure what that extra star was, and we'll never be able to see it. But our ancestors' record keeping preserves a part of it for us, and offers us a link to a time in the past when they looked at the sky with wonder just as we do today.
Thank you for all your efforts in 2023, Fraser and your team! I’m always exited when I notice a new upload in my stream. Keep up the good work and happy ‘24!
That simulation of WASP-121 b / Tylos was the most beautiful and awesome thing I’ve seen all month
If only we could see it up close
5:56 What supernova remnants do we know of that could account for the missing 29th "star"? Wouldn't that both help confirm the hypothesis, and be an additional data point for dating the discs? That's fascinating, I love seeing archaeology and astronomy cross paths!
Good question! Since it's on a star map, it should be possible to identify its position to... I'm not an astronomer, but surely within a degree or two? A proper survey with modern observatories might even find something new in that area.
Brilliant as ever Fraser, keep up the great work.
Thanks so much Fraser & Team.!! You make really fantastisk content, i've spent hours and hours watching and reading your videos, interviews weekly newsletter ... Thank you all so much
If you're really hankering to see the Aurora from right under the belly, book yourself a week at Manley Hot Springs, Alaska. There you can sit in a naturally heated very hot tub right outside your rooms. At 65°0′28″N you cannot find a better vantage point in the US. A little further South at 65.1090° N, Chatanika Hot Springs is a close second in terms of longitude but far more accessible, being within a reasonable driving distance from Fairbanks.
My first aurora was in the suburbs of Anchorage, Alaska. It was in November; the traffic was light and stopped at a fairly major intersection. People got out of their cars and trucks to look! You never get over it. I’d swear that I could hear it a couple nights, as the “huge snake” shook in the sky. I’ve since seen auroras in the Puget Sound area (northwestern Washington state) while camping in the summer. Getting away from light and air pollution really helps.
Just found you tonight and I’m Subscribed. (You had me with the first story.)
Great job team! Awesome!
If all of the fantastic content you put out, I think the interviews are my favorites.
ONLY 57 hours of content. Thanks Fraser and Team. Great work guys.
The time is just for the interviews
*Hey Fraser, I sincerely applaud you and the team for your 2023 totals, which, impressed me.*
*Admittedly, when I first began opting for your content, I was quietly skeptical of your potential. For that, I apologize -- your channel is like a breath of fresh air, as it consistently delivers on my endless curiosity and wonder for this breathtaking universe we inhabit. Thank you for your hard work and dedication. May you live a long, healthy life, with which you'll happily prosper. Cheers :-)*
The cool thing about the cat video wasn't the cat. It was the high-res video, beamed from far away. I can hardly wait for every probe to send back more stuff, faster, using that bandwidth.
I love all your content Fraser but these Space Bite videos are the best, not just from you but from all the many space/astronomy shows I watch. Thanks for all your great work 🚀🪐🌘
What a great time to be alive with you as the travelguide to explore all the new discoveries!
Another insane video. Nice one Fraser.
To be fair, given the number of stars in the sky, you could probably find a
star-map in a Jackson Pollock painting.
Best space journalist ever! Will help support when I can.💞
Will you talk about the Small Magellanic Cloud next time, and the recent (December 2023) result that it is actually two galaxies in the process of merging?
That is so cool! I hope they can get an idea of their individual shapes soon. We can update our space maps.
Always worth listening to you. Thanks for all you do
Mahalo for those news letters, Fraser! I'd miss some cool articles on Universe Today without them! Happy Perihelion!
Thanks for a great year!
Hi there my name is Atila and live in the Netherlands.
Just want U 2 know that this is solid and one of the clearest images and video's i've seen so far at youtube.
Keep it up !! Respect👍🏻👊🏻
Fraser thank for a very productive year of 2023! With everything that is ongoing , the future looks very bright indeed!
Thank you for all that you do, and I love you for being you! 🖤
As a child of the sixties I am absolutely gobsmacked by this concept of what it is to see into star planets.
listened to you and John Last night on event horizon, Love it when you guys are together!
Billiion...with three 'i's. That's biiig!
Thank you, my fellow ‘Courtenay’ite for your work! Love this channel! Infinitely more to discover and share! God bless you this coming year!
a particularly good and varies episode, especially the WASP 121b storms, wow!
I love Fraser’s barely contained skepticism about SpaceX. Or maybe I’m just projecting 😃 I can’t understand how an elevator makes any sense for getting people and equipment up and down to the surface of the Moon and Mars. There isn’t much room in the capsule area, and taking up a bunch of it with crane nonsense perplexes me.
Every time I see the renders, I wonder why no one mentions that pretty obvious failure point. WTH will astronauts do when the entrance is 40m above & something jams?
@@nicholashylton6857NASA and SpaceX have backups and contingency plans for possible equipment failures.
I mean, what’s the alternative? Massive ladder kerbal style?
Elon may be goofy but he’s got a lot of very talented people working for him. I tend to give them the benefit of the doubt.
@@oberonpanopticon For sure, they're the engineers and I'm not! (I think, though, that the entire project of putting people on the moon is a waste of time and energy, and it doesn't surprise me that the realities of it are more difficult and poorly thought out than the spaceX fans believe.) To me, Musk is the consummate overpromiser and underdeliverer, and it annoys me that so much of the space community believes him when he says he'll get people to the moon safely in less than 2 years. SpaceX flies by the seat of their pants -- they're just now making mock-ups of the elevator, to name one example. NASA's standard for human spaceflight safety have always been incredibly high, and SpaceX gets a lot of praise for trashing that methodology.
@@nicholashylton6857 CommonSenseSkeptic on YT is a fire-breathing Musk skeptic, and he's got many many complaints about Starship feasibility that I haven't heard anywhere else. He's a bit hysterical in my book, but he makes a lot of interesting points. He's been very critical about what exactly is going to take up the small (100 tons) cargo area, especially when it comes to taking people back and forth to Mars.
Great program. I learn a huge amount from you. I prefer the non-interview format.
Hello Fraser, happy New Year!
I would like to comment and say I cannot recommend enough watching NASA's media reel for last year.
When it comes to spacex's elevator they were actually testing it in the neutral buoyancy pool, and we have film of that event thats public.
We can see the astronauts training in the new space suits in the neutral buoyancy pool with SpaceX hardware. They did tests in lunar gravity where you fall over and get someone to help you up. They went over different tools they're planning to take to the moon and using them in low gravity. They even tested out a moon cart used for moving tools and carrying rock samples on the moon, all underwater!
NASA really released this huge media reel and didn't publicize it much. It even has videos of the Artemis 2 astronauts training in Orion!
It's released on NASA's CZcams channel and it's called:
Artemis ll crew training resource reel
great work thank you
Great video as always Fraiser! ❤
Q: how neutron stars have such powerful magnetic fields when in theory neutrons are *neutrally* charged??
Q2: when we often hear "a teaspoon of neutron trar material would weight..." and in scifi examples such as "an armor 1 atom thick made of neutron star material " (hmmm..sfia..) would that actually work? I mean, if you somehow take material out if a neutron star wouldn't it loose it's properties really quick (decay or smthing)??
Idk the awnser to the first one but the second one is inside whatever it is how it is just how it is in there
@@Snakeybloo thank you.
So, gadgets (as armor) from that stuff are unrealistic (except for plot armor 😂) right?
Stars are electrically powered, each one has an electric field that helps hold them together.
Neutron stars, don’t make sense and stand out as flaws in the standard model.
Welcome to your electric universe.
And before one of the scientism priests says, that’s pseudoscience,
read the paper, "The sunward electron deficit: A telltale sign of the sun's electric potential," which was published online July 14 2021 in The Astrophysical Journal.
Slowly but surely the paradigm is shifting.
Much ❤ Love

1) whether something is charged or neutral has (in principle) no bearing on its magnetic properties. On earth, magnets are not charged but still have magnetic dipoles. Magnetization in general comes from a macroscopic alignment of magnetic moments of constituent particles, which is proportional to their spin. Neutrons are fermions and they are spin-1/2, so they do have magnetic moment and can form magnets. I don't know the mechanism how they align their spin to each other but it is probably a combination of dipole-dipole interaction and an exchange interaction (but of different nature than in terrestrial ferromagnets, where magnetisism is a consequence of a stronger electrostatic interaction)
2) yes it would decay because if you isolate from the parent star, there will be no gravitational force to hold it together against degeneracy pressure. It will explode and loads of things may happen that have not been confirmed by experiment. I assume small balls of neutrons will immediately decay into a gazillion of very radioactive stuff via beta decay.
For the last bit there is a minute possibility in my imagination that it will be stable against decays when in large quantities because of some quirks of the strong force... Which would be analogous to a huge huge atom. But that is pure speculation akin to an "island of stability" of heavy nuclides.

@@mikoajmetelski18 thank you
I remember an aurora from back in the late 80's or early 90's, that was so strong it turned the sky red up and down the East Coast. We were out on a night xc ski in Vermont. It was wild, a bit freakish, but generally inspiring. I've always wondered if the powerful solar flare associated with it caused any damage here on Earth? Thank you for the coverage.
Thank you soooooo much!!!!!
Thanks for all the news, Fraser! 😊
But I'm too close to the Tropic of Capricorn... So I'd rather never see an aurora here. 😬
Happy new year! And stay safe there with your family! 🖖😊
What was missing from the Italian star map rock is a simple question (but a hard answer): given that from the map we know where the 29th star, the supposed nova was back then... can we accurately guess where it is supposed to be now (or rather how wide a search area) and are there any candidates? Would be great to look into with greater detail. The mystery of Sherlock Fraser and the Missing Nova.
I love your name. Makes me think of a sauna in Norway.
This episode has got me extremely excited for NIAC interviews this year!
Hey Fraser! I don't miss a video. Thank you for the fantastic work!
What happened to the recurring methane peak registered in Mars' atmosphere by the Mars Expresso (or the MRO, I don't recall!)❓Any news on what could be the cause and if they have been confirmed with more measurements❓ Happy New Year! :)
Hey, thanks for the great content. I would appreciate if you could more consistently declare in one corner of the b-rolls if we are looking at actual images or CGI renderings. I really could not tell wether the images from juno were actual images or CGI. Thanks!
Excellent!!! 👍
I totally see the running chicken! It's coming straight towards the screen, facing to the upper left of me/the viewer...considering the coloration as well, looks like it's frantically evading a fiery explosion, action movie style 😎
So much cool stuff this week! The vote will be tough.
However, when I think of all the Plan Bs they had for the Apollo missions, I just wonder if they will have the same amount for Artemis. That elevator to the surface of the Moon makes me nervous.
Maybe a ladder on the side of the lander?
If we looked at the area of the missing star in the ancient starmap could we find the Black Hole, or Neutron Star? Or, is it too hard, even if we know where to look?
I have seen good displays of the Northern Lights from Halliburtonr area of Ontario, as well as Tobermory, and Manitoulin Island. You should be able to see good displays from Vancouver Island which I think you are near. I have seen fairly weak displays from where I live on the Niagara peninsula. BTW, you are quickly becoming my favourite astronomy reporter.
Interesting to see how highly rated the cat video segment was. You should research more cat-video related space content and include one on every space bites release!
If only NASA would've looked at Thunderf00t several years ago they wouldn't have made that mistake.
In fact, I’m heading to Iceland for a few days next week! Fingers crossed for some good AB activity.
Thanks 🎉
Hi Fraser, I have a question for you. What is the distance limit of the transit method to find new exoplanets? I have the impression that all exoplanets found using this method are quite close to us
Hey really like your shows. Do you have a show on when stars become black holes? I'm more interested if a star can collapse to the point where it's borderline of becoming a black hole or something else. I've seen several black hole shows but none of them cover this issue.
how big of a helicopter could we realistically fly on mars? does the low atmosphere and required high rotor speed limit it to small drones only?
I’ve recently been wondering what kinds of aircraft might work on mars. Would very lightweight passenger aircraft be feasible for a future mars colony? Who knows!
mars was nuked.. are there still inhabitants, living underground. seeing earth, has thousands of miles of not human built tunnels, dwellings.. inc. pyramids.. @@oberonpanopticon
4:56 the star map. The skies were extremely bright, no light pollution, apart from oil lamps, fires,. It must have been an awe-inspiring sight to behold, the Milky Way, the stars etc
So i have a pretty powerful server computer at home. I know you have said a lot of people search through the data from telescopes on their own, i wouldn't be any good at that but is there some computing pool i can join to lend some processing power to the cause when otherwise idle?
Always a relief to watch. I can’t think of any time where it was click bait. Your content is always clear, understandable, and fun to watch, thank you (15:04 blliions? I’m a jerk)
How is Starship going to land on rough, unknown, unprepared ground without toppling over?
They have detailed terrain maps of landing zones they are interested in
Maybe I should build a Faraday Cage, Carrington Event Shelter for my computers, cameras & devices? And see if my car insurance would cover it. If not, build a Faraday Tiny Home out of a steel storage pod. Making sure the steel is thick & well grounded to handle substantial loads.
Canada Arm says "I'm sore-ee" each time it bumps into something 😊.
In the Spacex trend of calling fireballs success, does that elevator ride counts as human rating for the Starshape moon lander? It should, no explosions.
15:11 fits well across my 3 x 27" monitors on my desk :D
..about the ancient Star Map.. maybe Nr 10 refers to the Crab Nebula (M1) like pre-Supernova (maybe its the Star that turned into M1 after the supernova)?
Babe wake up, new Fraser Cain video just dropped!
14:32 It took me a while to find that image, but i did🤗
So can't wait to see pictures of other world's 🛰🌌☄️🚀
I've had this question for a while could have Jupiter been a rouge planet that got captured by the sun and migrated inwards and caused a massive planet to smash into Uranus causing its Tilt?
Fraser, first of all, great channel, great content, and super great tone and style! But, why, as a Canadian, would you not recommend Canadian locations to view the Auroras? Even if it’s just in the Yukon, NWT, or Nunavut? Shoot, growing up in southern Alberta, we often finished our summer nights, just laying on the lawn watching them dance and shimmer; MESMERIZING! Australia, USA, Alaska, etc. Sorry, just part of my bugbear at how we seem to be invisible to international media, that seems to lump Canada into the USA, never mentioning us re our Ukraine involvement, economic news, global oil supply, countries with a carbon tax, etc.
fascinating.
everything .
one week in.
Hang on. If the 29th was a supernova then there should be a remnant, right? Like with the crab nebula?
It depends on the distance, and chisel marks on stone aren't super accurate.
What do you think about the Napta Playa stone circles?
14:53 I absolutely see the chicken. 😂
Supernova chiseled into stone! Amazing!!!
Neutron stars are fascinating, but isn't there a rarer magnetar? I've heard of them, and I think they are stars that were just short of enough mass to become black holes. Can you explain magnetars, please?
Thanks for all of that in 2023 !!
Star disks man that's cool they made it because of a super awesome nova. That us so cool
Great video =) There are better places to watch the aurora borealis than Alaska, Iceland, and Antarktis. Would guess the warmest places still above the Arctic Circle (Iceland is below) would be the northern parts of Scandinavia (Norway, Sweden, etc.)
Any effort towards searching the "extra" star location for a nova remnant?
Is there a sky map showing relative redshift like there is for CMB temp?
Can you explain diffraction limits for apertures? Economics and Engineering aside. Could we make a Earth's orbit sized telescope and be able to see moons on exoplanets?
Running chicken nebula looks more like an ostrich 😂
The 3,600- year-old Nebra Sky Disc is the oldest map of the stars ever found. Discovered in Saxony-Anhalt, Germany in 1999.
assume proximity to magnetic pole is more important than geo pole for aurora visibility?
Re - Juno
What is radiation? Radiation is the emission of particles/ waves of varying energy. The more energetic the radiation, the more damaging it is to living beings.
Anyway, light is a form of radiation and we're able to harness that radiation to do work (ie- solar energy). I don't see what's stopping us from being able to harness ionising radiation from also doing work. When THAT day comes, probes like Juno would be able to generate massive amounts of energy from the radiation emitted by Jupiter.
Nb: Such power generation would have to be different from existing nuclear power generation, which just uses a nuclear reaction to generate heat and then uses that heat to turn water to steam, which then drives the turbines that generate power. So they're not harnessing the radiation, they're harnessing the heat. I would want to see a new type of power generation, which would directly harness the radiated particles/ waves to do work, rather than using it to generate heat (no different from a coal power plant, in that regards) to make steam to drive turbines.
Is there a nebula or neutron star of the correct age where the 29th star is on the map?
I’d love more info about the stone discs
watch.. viper tv sumerian tablets.. might learn something..
You should also be able to see it on northern Canadian and trans-Atlantic flights ✈️.
Thank you everybody at universe today and at this podcast
How did you get to be the best space reporter what was your biggest break-threw moment
Hi Fraser. Thanks for all your efforts. Recently I heard you talking about buying meteorites. I didn't know this was something relatively inexpensive to start a collection of. Do you have any advice of trustworthy websites to go to when searching for meteorites? What kinds of things should we be looking for when buying them? Also, in your experience, does the value of meteorites appreciate in value? Thanks for everything.
I don't know about the value. Personally I care. Regarding a trusted place to buy, check out aerolite.org/
Thanks for the reply, I will check it out.

My ideal was self sealing haul or system of the enviroment s o a double or plated wall with a reaction of a chemcia lgorup when a vaccuum is present it exands and plugs a hole. The purpose would be to instantly sealan immediate problem. WIth hardoning foam like system. Thus giving time ot repair it.. alternative, a internal wall filled with steal plates, could get sucked out nd form a lattice plug also... or a more advance matterial is a the wall when its doubled seal, acn create a vaccuum reactionary weld to teh area, when exposed...
Question: It is said that standing on the surface of earth is physically just the same as accelerating constantly with one G; certainly it would feel the same. Why then does time run differently for someone who, let's say, walks once around earth, all on 1 G, and someone else flies once around Alpha Centauri and back to earth, also accelerating constantly with 1 G?
Question: to terraform Venus could they release algae (or another organism )so light it floats in the upper atmosphere to convert a portion of the CO2 into oxygen? Thank you
