Halle Bopp was a sight to behold. I was a teenager, and I remember being fixated on it. Mesmerised! Frankly I'm surprised I wasn't run over, as every time I went out do something I had my eyes pointed up. I do so hope I get to see another in my lifetime.
Same. I remember staring at it night after night. Surreal
Same here. Now I'm a geeky dad and i want my kids to experience that. My sister said when she was in Australia about a decade later, there was another one she could see in daylight even.
If it's anything like Hall bop it will be the most beautiful comet I'll never forget 1997 I was 21 living in Baton Rouge Louisiana and could see it for a month and then we got heaven gates! So sad that that happened. 😢 😍
Literally once in a lifetime event. Cherish it.
@@jasonfalcon7821if there is another comet like hale bopp in our lifetimes, it will be a terrifying surprise
I know the selfie thing doesn't have any scientific utility, but a lot more kids can get inspired by these things and might decide to pursue their career in science and astronomy.
These news casts just keep getting better and better. Thank you. Amazing stories, explained clearly and incredible graphics! I watch a lot of space news and I’d say yours is now arguably the best one.
Those selfie cameras are REALLY cool. That's A-game material right there 😎❤
If you can land a rover on mars...
• in one piece
• right way up
• get communications working
Then you've done really well. Mars has eaten a lot of probes before even getting to that stage.
It's sad that the rover's shutdown, but it sounds like it's done well for such a harsh environment.
I like them too Kaylee but I am waiting for the naysayers who attacked everything about NASA and its cameras when we went to the moon. How many conspiracy theories have I had to live through that time and still do. Some people don't think that four countries now have with various probes and satellites and varying results filmed the history left behind by Apollo missions and you can even see rover and astronaut tracks and they forget the Russians sent up two rovers too which I haven't spotted on any footage but they'll be there and Alan Shepherd's two golf balls if someone can pinpoint them one day. How are those tiny minds going to believe a spacecraft takes along it's own selfie camera probe to take pictures of itself. More conspiracy theories. One thing sticks out in that lunar exploration era is that the one country who was in competition with the USA never denied men had landed on the moon,Russia didn't deny it as they tracked the Apollo's all the way there and back plus we had the joint collaboration of Apollo -Soyuz in 1975 when Cosmonauts and Astronauts trained in each other's countries and obviously information would be shared about past missions and the one they were about to accomplish especially because of the docking collar between Soyuz and Apollo and with all that information Russia knew lunar soil had been kicked. Luckily Deke Slayton of original Mercury Seven got into orbit after waiting 16 years for an irregular heartbeat to go away by the taking of huge amounts of vitamins. Sorry Kaylee I get off track a bit. I might be Australian but all those Astronauts and Cosmonauts and test pilot's plus the NASA organisation are heroes to me and to the exploration of the human spirit into space and other planets. Just wondering and waiting for the conspiracy theorists that haven't got anything good to say about how smart the human race is to leave its world but pick the adventure and technology to pieces. I liked your comment.
The Soyuz replacement was a no brainer. Would’ve been surprised if they risked using the current one.
I guess you must have forgotten about Comet NEOWISE in July 2020!? I saw it for three weeks with a tail that was from 2 to 6 degrees long depending on the night, the lunar illumination, and haze or clouds partially obscuring the comet. I even got some nice photos showing a full 6 degrees of tail in predawn skies of July 24th in southeast Michigan. It was at least as good as Hyukatake, and I had better views of NEOWISE than I did of Hale-Bopp - (the weather cooperated more often for NEOWISE). I've been looking for comets since the comet-FLOP of the century with Comet Khoutek in 1973 when I was fifteen; I've seen at least several dozen with binoculars and telescopes... but only Hyukatake, Hale-Bopp, and NEOWISE were easy naked-eye. Sorry you missed NEOWISE!
Fraser Cain very good to match the face to the great newsletter that arrives every Friday. I'm glad there are people like you to inform and break news and science down into chunks I can digest. I didn't know if I would be able to handle a whole heap of information in one go but you have a good flow going and like some videos of other topics I will fast forward but you kept me entertained and I didn't want to do that. I found I was hanging off every word. So much is happening and you are good informative voice to tell us. Thoroughly enjoyed it. Also good to see the name Webb from the earlier NASA years being used and I didn't know that. I was lucky to see Halley's Comet in 1986 after I had got off the grain train I had been driving from Adelaide South Australia to a little town called Robertstown where to see the comet easily we had to block out some streetlighing and it might have been the moon rising making it hard to see so I thought about the problem and improvised by looking through a toilet roll. Exactly the right size for the job and the comet was easily seen in the middle of the tube and enough paper to block out the illuminating problems. Hope you see your comet Frasier and cheers for the video. Eddy from Australia.
Great stuff man!
Thanks for thinking about us little people in the astronomy community.
Thanks for all the news, Fraser! 😊
Stay safe there with your family! 🖖😊
I'm going on vacation, underground.
Love your channel and content. Thank you to all your team.
I love that your march prediction seems spot-on
awesome, I hope the sky will be clear enough here where I live to find the comet!
Ohhh wow, I missed the dust disk. So cool. Thanks Fraser! Have a lovely weekend.
Great video, no ads, I'm sold, you gained a new subscriber with bell notifications on, thanks for not including ads, I look forward to watching your future content 🙌🏻
The pellet drive sounds really interesting. Thanks for a really informative session.
Thanks for making everybody cry Wednesday night!
Your opening comment about being owed a bright comet was an interesting perspective for me to hear. I was born in '98 so the only one I've ever seen was neo wise, and I thought it was amazing but of course I had to wait for my eyes to adjust and find a very dark area to see it. I hope I get to see my first bright one soon!
At least for this upcoming dimmer one I can consider it a bit of a birthday present, the timing is roughly right 😅
I'm looking forward to the interviews!! The titan plane looks bad ass
Thanks for your work!
As has been suggested by others,since our 'rover' and helicopter are up there to explore and run tests,why don't they aim them to the other rovers so we can send the copter over their landers and blow the dust off so they can recharge?If they get a signal back,then we know it's possible to do that and equip other landers to be followed and cleaned.
I remember Hail Bopp. That's the only comet I've ever seen with the naked eye. I remember there also being a spaceship behind it. 🙂
Yep. According to that idiot cult leader for heavens gate
I saw Neowise with the naked eye, though it was very faint.
Love this!!! Keep going.
Very interesting information. Thank you
I am newly subscribed because Fraser’s voice quality makes his engaging posts extra special.
Nice video. I do hope you'll find the cause of the distortions so you can keep them out.
An Italian running the ELT project visited the building site and said it felt like standing in the Colosseum. That says something about the size of it 🙂
What a great video thank u.
C2020f3 was visible and I watched it all night while camping in Idaho in July 2020. Had a beautiful long tail.
The summer of Hale-Bopp I had broken my glasses and had to wait 4 weeks for replacements. I'm still pissed about it.
Thanks!
I am surprised they don't have a way to clean/blow off the dust off the PV array, maybe with the Helicopter hovering over than PV array.
Here's a simple 'exploration design' the can use for future explorations on Mars; "A roller shield cover for the solar panels".When the storms are building,the unit closes down enough to be covered by materials that 'roll' out over it,and when the storm passes it simply rolls back up.Similar to a window shade.?The dust falls off the material as it's rolled back up and the solar panels,cameras,etc; stay clean.
I was totally disgusted when I read someone recently "explaining" that a magnitude 5 comet is FIVE TIMES AS BRIGHT as a magnitude 0 object. SMH
It's orders of magnitude. It's right there in the name. 😀
@@frasercain One detail worth mentioning. Unlike the term “orders of magnitude” in common usage is a factor of 10 per step. Stellar magnitudes are a factor of only 2.512 per step.
THANK YOU
Q: Since we’ve proven we can send ‘helicopters’ to Mars would it be worth sending one or more with a future Mars mission specifically to fly to the disabled rovers to remove the dust from their solar panels? Wouldn’t the cost savings for piggybacking relatively tiny drones vs replacement rovers to continue their missions be worth the attempt?
I guess it makes sense but to my understanding, the machines need power to provide heat to their sensitive equipment. Left in cold temperatures for a period of time will permanently destroy them.
@@sadderwhiskeymann Couldn't a type of blower be installed on or near the solar panels. With the last 1% of battery power, the power is used to blow the dust off the solar panels. Might not get all of it, but enough to store enough power to blow again and get more off.
I've also heard that the dust is electrically charged and clings due to static, so would also seem like a good idea to use some power to run a current through the panels to prevent the dust from clinging. That might make it easier to blow off at the very least.
At the end of the day, it is already too late for these rovers. These ideas aren't on them.
I don't think the cold destroys them. They all went through the cold of space to get there in the first place. Cassini was even put into hibernation mode on its way to Saturn to conserve energy and fuel.
@@DexLuther that was my idea also!!
A blower or some kind of liquid to clean the panels. BUT I cannot believe that you and I thought of something that NASA didn't, so... there's that!!
As for the cold, i am 90% sure that both during transport as well as during hibernation, the heating element is "on".
Furthermore, i am 60% sure that the cold destroys the batteries (and gawd knows what else)
I really like the idea !!
It still costs just as much to send a rocket to mars. Not to mention how difficult it'd be to land in the exact same spot as one of the rovers.
That planned NIAC series sounds amazing! Just the brief teaser has me guessing how we might attempt a "reverse" jet engine where the O₂ is in the fuel tanks and the hydrocarbons are ambient...
This was good!
Very surprising that in 2023 the Soyuz doesn’t have a redundant cooling system.
That rover. still a success.
That comment about a comet...
"the Universe owes me a comet"
I couldn't agree more !
I wrote a short post a few months ago about that very thing !
I saw the comets before the millennium (is that the right way to say it)?
...but nothing since then.
-Will I not see a glorious comet again ?
(Before my time is out) ?
Amazing!❤❤
Jeebus, Fraser, that sudden image of "Uncle Jack-sickle" was jarring... lol!
Thank you
Makes one begin to viscerally grasp time. We can look at one image and see objects both near and far at once in time
Hey! Great content, thanks! Maybe backup from the camera a bit 😊
I met the person leading the beagle Mars lander project at the open university in Milton Keynes (England) it's a shame that lander failed, it was designed to test for life. Apparently we later found out that the Lander did deploy, but for some reason it failed to transmit? Sadly he passed away before we got any news from it. Another British lander may soon be on its way to Mars via the European space agency
I always wonder why they don't design dust "sweepers" to clean the solar panels. Seems obvious.
Love me some tasty Space Bites! Thank you for the science snacks, Fraser!
❤️❤️
I remember seeing Halley's Comet in 1986 but it was pretty underwhelming. The greatest comet I've ever seen was McNaught in 2007. That thing stretched across the sky, it was awesome.
I love modesty backing things like Universe Today for exactly the reasons FC said. This seems like the right ad balance.
For northern hemisphere viewers Comet West (1975-1976) was the greatest visual spectacle of any comet in the last 50 years.
In a truly dark sky is was a giant ghost-like apparition.
My 2 cents.
My suggestion for Martian Rover improvement would be a spiral 'windscreen wiper' to brush the dust off the solar collectors. I would be very light and have downward brush fibers. As it rotated, it would gently sweep dust away from the center and then off the solar collectors.
Contact me if you have $100 000 reward for me!!!
Totally looking forward to NIAC discussions. What zany ideas live in the minds of zany scientists.
I was wondering why I wasn't getting bombarded with ads, it's nice!
What is really mind boggling is that photo of the galaxies shows a small section of how many there are ,and each one of those could contain billions of stars and planets astounding
I have a question for what I think would make a fun video. What mars rover would win in a fight with each other?
The Chinese lander had another feature that I hope NASA and especially ESA adopts, a black box, that sends telemetry back in case the lander crashes. Could have been really useful a couple of times.
Since it hardly ever rains in the Atacama desert, a full size paper version of the Extremely Large Telescope might not be the worst idea 😂
McNaught in 2005 was also spectacular.
I'm looking forwards to seeing this new one.
It was really only great for folks in the Southern Hemisphere.
@@frasercain I live in Australia and I remember it well what a site it was now it's your turn in the northern hemisphere
@@frasercain It was easy to see by unaided eye in broad daylight at nag. -5 and was shown to the public all day (before noon to sunset) at Griffith Observatory. My daughter could see it the next day during her soccer practice at noon.
Would the dust-repelling tech used on the new Moon spacesuits also work on solar panels?
Good stuff !
But at 14:18 I'm having a hard time to understand the scale.
I get that these are same types of galaxies, but at different distances away (/ago) and therefore have different angular size and redshift.
But what's the story with 4000 light years ruler? It's too tiny to be at galaxy scale.
Hi Fraser,
astrophotography isn't too old, but have there already been significant visible changes in nebulae, galaxies, star clusters, etc. over the past decades? Thanks a lot!
What about neowise a few years ago?? Did we forget out that? That was a nice sight!! That was the 2nd one I saw after hale-bopp
A Comet has Cometh.
About bright comets... did you forget comet Neowise in July, 2020? At it brightest it was naked eye visible from my fairly light polluted site in Hesperia, CA! Peak brightness in early July was reported to be magnitude -2. Bright enough for you?
I saw it. I demand nothing less than another Hale-Bopp. :-)
OMG!! I will be 59yrs old ,in Feb. hope I see the comet!!!
Its strange why the don't make a rotating conveyor belt of clear film that can keep the solar panels clear , maybe with a light brush so as the strip goes round it can clear off the dust so when it comes back round it's clear enough for the panels to receive enough sunlight for power
I've always wondered how small you could go in building a radio telescope.
I remember a movie years ago where a disgraced astronomer posed as a cable tech and supposedly ended up building a huge network of satellite dishes that he could aim.
So just how feasible would it be to build a small setup. I imagine that smaller dishes and fewer would restrict such a setup to a fairly narrow wedge to look at.
Just an idle thought...
Are we recommending the said advertisement for mood to enhance our comet watching experience?
All that tech in the rovers and they forgot the solar panel dust blowers. Never forget the simples, They save the day.
Hey Fraser. When will we see the next "great comet"? The one that you could see without binoculars and that would take your breath away...
When I was a kid I saw a bright comet when I got out of bed early and went in my backyard. It filled half the sky yet I can't remember it's name. Must have been close to 60 years ago now.
Comet Seki-Lines 1962 most likely.
@@executivesteps I'd have been 8 or 9 at the time. I still remember how amazing it looked. I thought it was a common event. LOL Maybe this is why the ancients believed it to be an ominous sign. Naked eye comets are very rare.
@@stevelenores5637 they were ominous because “plagues” followed.
@@raycar1165 There were always plagues back in those days. Sanitation, food safety, and general health conditions were poor. There would've been even more sickness except for the fact that cooking food also made it taste better.
@@stevelenores5637 Tess Clark of mythosdecoded has written a book on this subject. I can't post links here but her website shouldn't be hard to find. She recently took down most of her videos on yt and moved them to odysee.
I got to study Hale-Bopp through NVGs far out from city lights at Fort Irwin for a few nights. Still disappointing
Were going to call it comet Frasier here, hope we see it.
I know I'm not hoping for more comets! One with our names on it is certainly on a direct collision trajectory with Earth, it's happened many times in the past so it's a matter of time until we take another hit! Yay ! A comets coming!!!!🌏🎯🌠
The comet isn't green, it's blue. It's called The Blue Kachina. Native tribes all over the Earth have stories they've passed for generations about said 'star'. It leads to global change. It's one of the first 'signs' found in the sky. I highly recommend everyone look into it.
You were talking about the Insight rover and mid sentence you switch to the Chinese rover. That was confusing. Wasn't sure what rover you were talking about.
It's the real time video from the surface of Mars that made the Chinese mission so incredibly cool. Imagine time-lapse sun rises and sets. Mounting them on future rovers and helicopters. (All real time and color corrected video too!)
Thanks for another great episode Fraser, but can you please tell us when we're seeing animation verses real footage, such as with the Chinese Rover at 4:56? Usually I can tell, but in this case, it is not at all obvious to me
I mentioned at that moment how it set up a separate selfie camera to take a picture of itself. The one where it's rolling back. The one that shows the panels deploying is an animation.
If a picture looks crappy, it's probably real. 😀
@@frasercain
Thank you for the reply. I heard you mention the camera at that point, but tend to think still image when I hear "selfie" -- and assuming is something I hate to do when it comes to motion pictures from another world.
Your passion is evident in these wonderful videos, and greatly appreciated here.
NIAC interviews sound great.
Im in west scotland..please tell me which direction ive to look. Thanks
The God of comets clearly has something against us southern-hemispherists.
But you guys get the only other galaxy visible with eyeballs.
A comet is always coming and there is nothing we can do to stop it.
I have a spotting scope with 15 to 30 power zoom. I'm due a comet as well. I just wish I had a way to relieve eye fatigue by using a camera and laptop.
That's the perfect instrument to see it. Follow a line across the top of Ursa Major to Cassiopeia. You should see it in a few weeks.
I have viewed Jupiter once but seemed a little blurry. I could make out the planet and color kept shifting. Never saw the red spot. Atmospheric conditions may have hampered a good visual.
Saturn on the other hand was beautiful to behold. I felt transported back in time and could imagine what Galileo and other astronomers felt with their limited technology.
These rovers should be equipped with a small brush and programed to do a bit of cleaning from time to time. It wouldn't be hard to make it happen.
Yes! I live where there is zero light pollution. I remember!
I am still disappointed in Geordi, he still couldn't deal with the coolant leak, I guess we should be happy he at least didn't have a warp core breach this time.
Since China keeps everything so secret, that rover never really existed to me anyway.
Wasn't there a comet like- last year?
Sounds like they forgot to put a dust buster on board the Mars Rover
We should take up a collection from all the countries in the world and build a REALLY big telescope. We can call it the Super Huge International Telescope.
If you remember in 2019 around October that we supose to be hit in the ocean an large coming from space, all those disaster never did come close.
How many time in human history we've been through the end of the world, sound like a scenario movies.
My father been through this and pass away at the age of 89 in 2012 and me i'm 61 yrs old this year.
Some year back i've look the hisotry of the end of world and the list go back a very long time
I can't see Cassiopeia on your star chart. What is 11/1 on the chart at 2:10?
"Heeeeere's Zhurongy !"
Comets are portholes opening in the dome letting a ethereal light through look at the trajectory it’s in plain sight
Years of studying at university all kinds of accolades but yet not one of these scientists have thought of installing a simple brush onto there rovers to brush off the dust thus enabling the mission to not end prematurely
Do you seriously think no one has “thought” of using a brush. Likely it’s been tested and it doesn’t work very well because of the extreme fine grain nature and other properties of the Martian dust not unlike lunar soil?
can i ask a question? they say that nothing can escape from a black hole not even light so why do they show pictures 2 beams of gas( or what ever it is) coming out of it poles? and if this is really the case then dose that mean the gas(or what ever) is traveling faster than light to escape??
love the show, i have a question! photons of light have been shooting about since the universe started, with more added every second, what is the total mass/energy of all the light ever emitted everywhere? how could we even start to estimate such a number? and could this number amount to a significant fraction of the total mass/energy of the universe?
photons are massless which is why they are able to travel at the speed of light, no pun intended.
@@xKanastax but they do have some energy, and mass and energy are interchangeable, so i think the question still stands :)
Its not been decades ,since a Comet was able to be seen with the naked eye, Comet Neowise was easily seen with the Naked Eye, and was around for a couple of weeks, and that was only 2 years ago, 2020 I think it was, didn,t need Binoculars to see that !!!
Why dont the solar panels have windshield wipers?
