Ha! The wife and I were definitely around in 1990! Retired SLC-4 engineer here, ever hear of Titan II, III, 34D or Titan 4 A or B? I helped launch them! Watch you every week too! Great channel, concise, timely and accurate.
That's fantastic. Of course, amazing rockets.
Amazing!!! Thanks for setting the stage for all these wonderful adventures! Cheers to you and the family!
That's awesome . Didn't they launch the voyager probes
"My favorite telescope Gaia" Sounds like a 70's family hour TV show. Comes on right after The Brady Bunch.
Playing RimWorld while listening to the latest ep of the person that suggested the game. Full circle! Thanks for talking about the game; very glad I picked it up.
Also, went back and looked today at how long Ive been supporting. Its been 7 years!!!! I sure thats no record, but that blew my mind. Wow time flies. Keep up all the great work and thank you!
Thanks a lot! Have you completed the ship and escaped the planet yet?
@@frasercain I haven't. I just got my ninth colonist and a full wall up around my complex. Feeling pretty stable and research is going strong. Getting braver to maybe start sending some groups on some longer trips towards the ship parts quest.
@@frasercain Update: I mixed up the ship mission. Guess its a "ship ready to go" per the message. Thought it was just parts. Could be Willy Wonka's for all I know; none of my plans happened, lol. Toxic rain, a volcanic winter, a caravan broke down and almost starved to death before the others got there, a cold snap took out my entire garden and we have been attacked like 4 times. Life is hard out here on the rim!
been following you since the days off hufffington post :)
keep up the great work fraser
Old school. Were they reprinting our articles there?
@@frasercain you was doing the online stuff and i loved that you always had time for us nerds in the chat section hehe
anyways wanted to say thank you for doing what you do good sir
Universe today is amazing, you’re amazing Fraser! Thank you for all the amazing content, you have no idea who I am but you feel like family to me I’ve been enjoying your content for so long 🤗🤣
Thanks a lot, I'm really glad you're enjoying it.
Regarding the Starlink satellites you did not mention how a solar flare caused a small percentage of them to burn up before they were operational. It's all good though, Starlink just tried again and there was no issue caused by the loss of a small percentage of satellites. YMMV. For Starlink, it was all just a risk they had to accept, and they did an admirably good job of recovering from it, despite the setbacks it caused. Congratulations are in order, in my opinion, to Starlink for getting past it by whatever means necessary. 😁👍
I was 22 in 1990 so I do remember. Problem was no internet so any info available was in dedicated science mags that I couldn't buy.
Isn’t lunar regolith effectively powdered shards of glass? We’re probably going to have to process and treat that stuff pretty extensively to be used as a medium for agriculture. I imagine by default it would stab and strangle most plant life to death. Like rolling around in a bathtub full of thumbtacks.
the lunar regolith acts like powdered shards of sharp, electrically charged glass, but perhaps we could erode it down in big rock tumblers or something
It lacks the nutrients and biological activity. The plants would wear it smooth pretty nicely, but they can't grow beyond just cracking out of their seeds.
In many cases, plants growing back after a volcanic eruption have to deal with a similar problem. It doesn't prevent them from growing.
@@frasercainso long term lots of poop I guess.
Lichens were then first to invade land in Earth's history. Their secretions chemically broke down the bare rocks they clung to. Then their own decomposition adds organic matter. Perhaps lichens are in the moon's future?
Thanks a bunch for the news, Fraser! 😊
Stay safe there with your family! 🖖😊
dude, how freakin incredible... What a time to be alive!
Great content as usual, Fraser!
Incredible week in space news and Fraser makes it possible to understand enough to follow up and learn more. Thanks FC for keeping us up to date with these incredible discoveries.
D'awwww, baby stars. They're so cute at that age.❤
Awesome as usual! Nice job Fraser.
Your excitement is infectious. I love seeing you get excited about all things space, you make me feel like I'm getting in on the fun. Thank you so much for doing what you do.
I'm glad. I never get bored of this stuff.
People with pacemakers should not approach too close to the magnetic fields of a black hole.
I am so excited for Veritas. I've loved all the Mars research but, we know so very little about Venus. Also, I will have you know, I was born in the mid-1970's, sir. Thank you very much! 😉
I DO remember Magellan. Born in '64 and started working at JPL in '87 changing tapes for the Voyager Neptune flyby.
thanks. just subscribed to the newsletter after months of following your videos 🤩
Good timing, I'm just wrapping it up
Thank you for your work
For newbies, those images haven't brought us images of the event horizon of the black holes. They show the shadow of the back hole. The event horizon is somewhere in there. The edge of the hole you see isn't the event horizon
Was 35 in 1990. And just a couple of years after High School I remember the Voyager 1 and Voyager 2 spacecraft launching. And remember setting on the living room floor watching the Apollo 11 landing after just turning 13, slightly disappointed that the landing had been delayed from being on my birthday. I first got interested in rockets and space by seeing the blastoffs of the Gemini missions. Yeah I remember. The only real disappointment, not being young enough to probably see the manned missions to Mars, or being able to fly transports to visit the Moon.
I was 31 years old in 1990. Decades before, I watched John Glenn in his capsule. I certainly was around for Magellan.
You *"watched* John Glenn in his capsule?"
I listened to his flight on a 5 tube radio.
(12BA6, 12BE6, 12AT6, 35W4 & 50C5)
We didn't get TV until Gemini 7 flew.
End, Endless Wars and we could accomplish phenomenal space exploration and have Real health innovations. But, there’s evidently not enough grift, in those distinguished endeavors.
I was born, and I do remember Magellin.
With EHT's new image of Sgr A*, VERITAS making a comeback, and supernovas unfolding in real-time, it's safe to say the cosmos is putting on quite the show!
Beautiful!
Love your channel.
I hope the cloud tops of Venus are one of the first major tourist attractions of the solar system in the next century.
Extremely dangerous imagine if there was a tragedy and people crashed on the surface what a way to go
I remember the Venus mission! We are not all teenagers :)
Some nice new visuals 😀
Thank you for these space news!

Hey Fraser. I have a question that has been bugging me. I live near an airport and as I stare out of my window on a calm sunny day, I often see many very distant contrails- in the foreground there are some trees in my backyard. The interesting thing I observed is that the contrails seem to move. As in the whole thing moves to the left. This is easy to notice with the tall trees I have in the foreground. I am wondering if this is only due to wind shear at higher elevations or is this actually due to the earths rotation? They always see to move from right to left as I look to the east. Comparatively, the clouds are barely moving at all and there is no wind on the ground.
Thanks for making great content!
Yeah, it's wind. Everything on Earth already has the inertia of rotation. You're already going 1000 km/h standing still and you don't feel it
9:45 It look like lawn chairs are about to unfold on Venus. Right before this pic, you said, ""mysteries are about to unfold on Venus", so maybe I was primed... but that spaceship looks like 2 of the old fashioned folding outdoor lounge chairs, with the plastic tubing. Now every time you say "launch date" I think "lawn chair".
The magnetic field lines around our black hole is so cool.
I was wondering where your Polls are located. Thanks from mentioning they are found by clicking on the "Community Tab" of your Main page.
Excellent show today. A lot of big news imo
Wonder if with the polarization images we can deduce more about the magnetic field around and the rotation of Sagittarius A*.
Do m87* and sagA* have opposite spins?? The magnetic lines in the side by side show opposite spins
I'll have you know in 1990 I was getting ready to leave school.
some of us are indeed old. =(
In 1990 I was a dirty thought in my dads head XD
I was learning to walk and talk, probably. I'm told I was obsessed with firetrucks around that time.
Hey Fraser, I'm interested in past, current, and proposed mechanisms for regulating human activities in near-Earth space. Currently, if a billionaire wanted to fire confetti into orbit to give Earth rings, nobody could legally stop them. Doesn't that sound like a recipe for a narcissist to ruin things for the rest of us?
They'll still have assets on Earth and be a citizen of a nation, so they can suffer consequences if their country has laws.
@@frasercain Near-Earth space will probably go the way of our oceans.
how do they get the details in the magnetic field lines of the pictures shown, given those details are at much higher resolution than the actual blackholes which themselves are presumably resolved at the limits of the EHT?
It's the polarization of the light that provides information on the magnetic field lines, they don't detect them directly. But measuring polarized light is much more difficult than just measuring light.
You got me, I wasn't born in 1990 yet. And I'm 32. So Venus is overdue for some new probes lol
It’s so funny that the moon will get its own Hyperloop before California.
The GAIA team deserves a Nobel.
I wonder whether a relatively simple still would work on the moon. Something like a dome over an embedded heater to collect volatile chemicals. They should collect on the dome and slowly run down it to a collector.
This is amazing. Thank you for the content. How is it possible that our species is capable of creating all of this but still be unable to find new ways of resolving our conflicts. How is it possible that in 2024 countries still need to fight wars between them. I really don't get it. I think we have the skills and knowledge to get there, just we aren't thinking about it
The EHT is remarkable. I watched the Netflix doc on it - curious to see how they're storing all that data now, as opposed to when they started. It seemed like the sheer volume of data, and then the task of transporting/delivering it was enormous. Hopefully quantum networks are just around the corner!
There seems to be more Starlinks over Sahara than over the north European countries with no Starlinks over Sweden, Norway, Denmark, United Kingdom, Netherlands, Poland and half of Germany.
Damn, that low orbit traffic will be crowded soon.
Of all the things to spend scarce funds on; the hellish world of Venus. Even our moon is more interesting in that it will eventually have a permanent human presence there and may provide resources and capabilities that will make Mars an attainable goal.
Can you provide us with a status update on the ELT, Giant Magellan, 30meter, LLST, Roman and the square kilometer telescopes? They are the most exciting new projects to me, but I never hear about them. Have they silently died?
I hope I see this happen. Twice in my life time we go to the moon. I did a trade with a friend in California back in 6he early 70's for his photograph of earth from the moon for a copy of the diamond ring shot of the sun from the Bridger Mountains full eclipse.
What do the magnet field line images of black holes tell us?
That the magnetic field lines run tangent to the plane of the galaxy, the polar jets, and we here on earth have a perfect birds eye view right down the center as if we are somehow are connected like its all for show?
Psh I remember the Magellan spacecraft, although I was only six years old when it launched so I didn't fully understand it when my Dad talked about it. But I did come to like Venus before I came to like Mars, which was thanks to Magellan and Venera.
It doesn't seem particularly good news about Starlink and others?
Astronomers have said some years ago, that this will interfere with their observations for one!
A Hyperloop on the moon would be a pressurized tunnel.
Yes, I remember Magellan in real time...
Yes, I am old :)
Yes!!! European Space agency goes to Enceladus!!!
I remember watching Neil Armstrong set foot on the moon - narratedby Walter Cronkite :) (10 yo at the time)
I was born in 86 and grew up watching Beakman's World. Also my beard already has white spots
So a question for you. We see bars at the center of galacty, what are they? I believe I know. What do you think they are? Peace ✌️ 😎.
*Tears* Yes I was born yet! Why you gotta be so hurtful? huh??? ROTFLMAO 🤣🤣🤣 Thanks for rockin' everything you do!
What would happen if we dropped an asteroid of a size worth mining from orbit assuming we'd stripped all other velocity from it at the point we drop it?
What? No video clip of the supernova???
first a radio tower had to be built on the moon
Watch: The Black Hole Image - Data Fabrication Masterclass!
Watch:Three Honest Astronomers Agree - The Black Hole Image is an Artifact?!
Wow it’s been a busy week 😂
So the supermassive black hole at the heart of the Andromeda galaxy is too small for EHT to image?
Q: What are the odds that some microbes that inadvertently attached to the landers sent to Mars actually survived? Is it possible that there is life (from Earth) on Mars?
How many astronauts are optimal on a longer spacemission, lets say to Jupiter if we think of the sanity of there minds? 1? 2? 5?

I have a selfish comment to share... youtube comment section doesn't seem to lend itself to discussions. Seems to me it is more of having people shout there thoughts into the wind. More like an irc - aol or discord chat room. Message boards allows a way to separate subjects - titles in a chronological format. I give eevblog as an example. There is a youtube channel and a forum board.
I've run forums in the past, it comes with a whole additional set of responsibilities, politics, etc.
@@frasercain Yeap -- When someone says it's easy Remember to laugh at them as you slap them.. Reminding them it's always easier said then done.
I've never heard of irc-aol, discord, message boards and eevblog. Are these social media that kids play with?
@@douglaswilkinson5700 New - No - It is some old stuff. As usual, Nothing is really invented out of the blue, it's built/added to in increments ""like the airplane - nobody invented the airplane, ideas were added to it over time"" One can say the grandfather of social media. Internet Relay Chat (IRC) came before( aol) America online - The aol chat rooms were an upgrade to IRC and then discord server/channels seem to be an upgrade to aol chat rooms. MySpace / Facebook chats were built of the stuff that came before.
I hope that sounded coherent lol
1:54 looks like a Gordian knot.
i don´t understand why you should use moon regolith? the most effective greenhouses on earth are not using eart soil!
Gaia is your favorite telescope? Was it built in Canada?
I didn't say my favorite robotic arm. :-)
It is from the European Space Agency
I think they should be careful to clarify that this new "image of Sagittarius A-star" is effectively just the actual image from years ago with a simulation of magnetic field lines superimposed over it, Photoshop style. They _did not_ glean the kind of detail you'd need to be able to sincerely state all those individual, thin lines are indeed what they specifically measured. Take a close look: Many of them suddenly end (or begin) in an unrealistic, very artificial "CGI" manner. (1:50 lower right quadrant has a lot of these.) But since this clarification is not being offered, the only data 99.9% of folks are going on is that this is indeed "a new image." I'm not happy with the smoke and mirrors of the whole thing.
It's an image of the polarized light caused by the magnetic field.
@@douglaswilkinson5700 It's a _simulation_ of that image, superimposed over the actual image of SgrA. Look closely and you will see many of those thin lines beginning or ending at a hard point. Magnetic field phenomena do not work that way, _period._ What _does_ work that way is a simple Photoshop CGI effect.
@@Asterra2 If what you say is validated by peer-review then the scientists who worked on this project will not only be humiliated but will also lose their jobs.
@@douglaswilkinson5700 I already chatted this topic up in forums. Even if you decide to ignore the inconvenience of "magnetic field lines" which begin and end with CGI-like hard stops, intuition should be all you need to at least be suspicious. The amount of "resolution" the lines in the new image offer is literally over a hundred times better than the resolution of the original image, and that includes the updated version that was provided a bit after the first. It does not wash. But nah, the painfully artificial phenomenon of magnetic field lines having visible start and end points, like strings of spaghetti, is really all the giveaway you need.
@@Asterra2You stated that, "I've already chatted this topic up in forums ..." 'chatting' is appropriate in poli-sci, history, etc. and in daily life however it is not in the field of astrophysics especially when one challenges the process and outcome of a groundbreaking research project.
I.e. a challenge requires (for example) independently verifiable evidence and mathematics for each finding with which one finds fault.
Look at the "Journal of Astrophysics and Astronomy" for examples of peer-reviewed papers.
Hubble pulling its weight still.
plant groving in regolith is good but can we eat theese plants.
Sure, it's just the same raw elements as we have here on Earth.

Watching a supernova in real time sounds dangerous.
Watching SNs in another galaxy from Earth would not be dangerous.
@@douglaswilkinson5700 It also wouldn't be in real time.
@sledgehammer7473 As Fraser explained -- astrophysicists, et al use the arrival of the EM radiation, gravitational waves, etc. *at Earth* as the timestamp for events.
Constellation is the wrong word, makes it seem too small. It’s an Orbital Horde.

Everything else is blurry, but the lines are sharp? I know the image was created with data of radiotelescqopes, but still...
as far as i understood this type of imaging is that the data is put into a model that then creates an image according to its parameters. so, the lines are probably just artifacts of the creation process.
not sure why they leave them in and if they have any relevance.
If aliens lets say.. existed... An they looked towards us.. Wouldn't they just see a very young proto-star?
Trains on the Moon? Trains across the car-addicted United States would be a better start.

I've always thought Venus was an interesting planet.
you've been a grump about Mars too mate.
I guess I just have eyes for Enceladus right now... :-)
Good length content. Usually its too long fer my brain and I give up half way thru. Maybe I need a new brain.
The Sgr A* image reminds me of an elephant's eye.
I like to imagine that all these NASA backronyms are invented by one guy who does nothing else. If you need a name for something you go see Dave and he'll come up with something.
The only way you could get an image even close to this you would have to above Sag A Star looking down at it, this image is AI generated.
To call it AI generated completely ignores the vast number of people involved in collecting and processing massive amounts of data over a large period of time in order to create the image at all.
These people clearly don't exist and no jobs were done, no work conducted by anyone, just an AI image, yeah ok bud.
Its axis of rotation roughly points at Earth. So we are above it. Thus your observation helps confirm its accuracy, not contradict it. Check all the relevant information before you jump to the conclusion that people have lied. Of course checking before being convinced it is true is also a good idea.
Think about how the black hole was formed. Multiple mergers with other galaxies coming from random angles will result in black hole angular momentum that is most likely not aligned with the galactic plane of gas and dust.
@@johnbennett1465 The polar jets of Sag A shoot out perpendicular to the plane of the galaxy. The field lines should mimic our observation of the jets. This image does not, and is in conflict with the polar jets.
@@michaelstiller2282 in the last few years the axis of rotation has been directly measured. As I said it points roughly in our direction. The divergence from the jets is an active area of research. I don't know what explanations are being considered currently.
14:51 disgusting
Here is a question for your question show……
Should some space entity…. government or company……do a mission ramming many ball bearings in to the Lunar pole before any usable science equipment is stationed there? The idea would be to create lunar excavation to make it easier to access sub-surface resources in the future?
There is already the Lcross crater. this would just add a bunch more.
if the Andromeda galaxy, for instance, is 220 thousand light-years across, that is how long ago the farthest away part of it is now compared to the frontmost part we see today (it's less, but just for the sake of argument, let's just say it is still quite a lot), so what we see isn't the correct shape of it, right? We'd need to "move forward" all the spiral that is farther away from us to compensate for that, so I wonder what it would look like, I mean, not only Andromeda but every other galaxy that is not perpendicular to our view. I don't think I've ever seen anyone mention that.
And I don't mean just colours due to the Doppler effect, I mean the entire shape of galaxies is gradually skewed ("less of a spiral", I suppose?) the farthest away they are from us, has anyone tried to visually compensate for that yet?
It trickles down, and it trickles up from our perspective. Peace ✌️ 😎.
Suspicious observer says that that photograph is fake AI generated
No he doesn't. Go watch the video again, and try again.
@@michaelstiller2282 Again.
I guess you'll have to decide who to believe then.
@@frasercain So we have this really nice head on shot right down the middle of the field lines? Like a dart board is facing Earth?
