Honestly most news theese days is bleak and depressing but all your videos actually keeps my curiosity and child like wonder alive. Thanks Anton. Ya giving me a lil hope out here. 👊
IKR? Positivity is hard to come by these days, Anton is a real mood lifter.
Very informative and interesting imo 👌
Great comment!
👊
You've got the camps reversed. Lucy visits the Greek camp first. Patroclus, despite being named after a Greek, is actually in the Trojan camp. Hector, who was a Trojan, is in the Greek Camp. This is because they were named before the segregation into two camps occurred. Either that, or they're spies.
I’m just
Bizarre discoveries we can't explain are like... our favorite thing.
One thing I like about this channel is if he says scientists can't explain sumtin its not click bait and I watch attentively
Go Lucy, please surprise us every now and then. This footage is great, and real sharp.
Thx for all your updates (and have a great lunch). Dinkinesh, Anton
That walk to the intro was totally worth it. I actually got a good laugh out of that.
That’s one of the best intros you’ve ever done! Loved it! Great Segway!
What a wonderful coincidence!
Pop Quiz trivia - "Lucy" the hominin was supposedly named for the Beatles' hit "Lucy in the Sky with Diamonds" (according to Don Johannson's book, anyway), which makes the name of the NASA probe very appropriate!
Remember, Anton, that you are a wonderful person to us 😁
I always first give a like then watch the video, simply because Anton consistently delivers amazing content. Keep up the good work, by far my favorite youtube channel for a long time now
Agreed, Anton consistently delivers great explanations of current science and technology topics. Much better than some others on CZcams who have too many bells and whistles or stray from technical topics.

4:20 minutes intro. Must be a new record for Anton.
Hey Anton! Enjoying your presentations enormously. They are brain food for me. Keep going you wonderful person! Lots of love.
I think that we're going to discover some weird stuff as we get a better look at these small objects. There are so many in such close proximity that they will wind up having some really interesting interactions and combine into more complicated systems than we initially expected. Heck, the "images" of the objects that Lucy will be visiting tells us a huge amount - we don't even have bad pictures of these things. They are literally a pixel or two wide at most in our best telescopes, so we have to fake it with artistic representations of them. It's a great time to be alive!
Artistic representations suck.
They don't want us to see Ceres
@@infinidominionIs that any surprise? There were city lights shining up at the spacecraft from center of a crater!
Ppp
@@-108- city lights?
As the first piece split away, there's no reason not to think that the piece that split away actually split away as 2 pieces. And since they would have been projected outward in the same overall direction, they could have each tumbled in space for a period of time before coming back into contact with one another, with both pieces now facing different directions than when they split away.
This kind of peaceful and interesting news is really welcome all things considered
Anton, I think the representation of asteroid groups should have a warning saying, "Asteroids in this clip definately appear closer than they actually are". Incredible information. Great work.
I love the little bits of comedy you chuck into your videos mate, and this videos intro was spot on. Awesome content! 💪
It was reported that the hominid "Lucy" was originally named after a popular hit song by the Beatles called, "Lucy In The Sky, With Diamonds"
The rumors at the time was that the song was about the drug: L S D
John Lennon reportedly claimed that it was about a drawing that his son made about a classmate Lucy, in the sky, with diamonds.
Just filling in the background story, as best I recall. ;)
I'm glad Anton acknowledged his lengthy intro because it is getting longer and longer each time...
Who cares his education is top tier and completely free stop complaining like a weirdo and maybe thank him, buy him a coffee maybe?
@@energetic479
Christ autismo, you worship harder now you gonna turn into a cult...
Wonderful as always Anton. Thank you. 👍🙂
I was getting worried Anton.... 4 minutes without hearing how wonderful I am.
Love your videos and everyday I wait for your upload conveniently around the time I get into bed. Keep it up!
Thank you Anton!
Always an interesting scientific topic and video.
You are awesome!! 😁👍
Space is not only stranger than we imagined, it might be stranger than we can only imagine - which is why we must explore it!
TY Anton for the updates. Now I really love Lucy. ❤️
I can just imagine the excitement in the room when that contact binary was revealed.
Whenever I see Anton's name pop up on other YT channels it is always conjoined with the word, "WONDERFUL". Thank you for making it a better world Anton! It's simply wonderful what you do!
I just get flash backs to a particularly horrendous mission in Homeworld when I see this stuff. My poor fleet!
I absolutely love the intro Anton! You too are wonderful! 💖
Great video from Anton once again! I love how the best intro ever peaked at 4:20 . 😂😂❤
Can we give a moment to the fact that this footage is from when the mission started, 10 years ago?
Anton is a cultural treasure, no less.
Thank you Anton for making us aware of these amazing findings.
I love these videos. Anton continues to amaze even after all his decades on the air. Thanks, my friend. I went through all my Patreon payments recently, and the only science ones that survived the cut were yours and Sabine's.
His decades on the air?
@@sjzara I know right
Nasa it appears spends time playing games..Deception is popular...There are thousands of asteroids only 1.2 million miles away..When more than a few hit, they of course, will all come at us directly from the sun..Nobody can see them coming if looking directly into the sun...The public will accept the answer...That's how we got here in the 1st place..
How many years this lady been watching? Decades implies 20 years at a minimum 😂
Ed only been on YT for 12 years😂
As expected, the universe is full of wonderful things!
Alltid lika spännande vad du ska presentera i dagens video! Varma hälsningar från Sweden :)
Hej från varma Los Angeles!
I am still always happy for new stuff from you sir, I thank you.
Thank you for making these videos Anton 🤘
Could the astroid have shed two moon's over time, then these two moon's came together to form the contact binary? Wouldn't it make sense that if these asteroids shed one moon, they'll eventually shed more as they speed up again? So, shouldn't it be rare to find them with only one moon?
What I was thinking. Or maybe it broke in two as it was shed. Either way.
It probably broke in two once it became unstable and started orbiting.
If mass shedding can shed one lump then why not two (or more) at around the same time? It seems sort of intuitive but I don't have any expertise to rule it in or out.
This is really fascinating. Excellent report and analysis, as always. And of course, I love how you always end with a big smile! 😀
Such an awesome video Anton. One of your best ❤
This one was awesome. Lucy's already finding diamonds in the rough.
Thanks Anton, for another wonderful video, this Lucy is some piece of kit, the images are astounding. Stay Wonderful, keep on waving " we are " PEACE AND LOVE TO EVERYONE ❤❤.
Wonderful as always. Thanh you.
Great video, Anton...👍
Lucy was named after Lucy the ancient hominid who was named after the Beatles’s song “Lucy in the Sky with Diamonds” which was named after LSD.
So…
…there’s that.
yup
The universe is a trip isn’t it
@@Chill_Mode_JD Cellophane flowers of yellow and green.
"Lucy In The Sky, With Diamonds" was named after a drawing done by John Lennon's son, Julian. The name had nothing to do with LSD!
@@stevenkarnisky411 Ha Ha! Yes, that indeed was the story John told to reporters at the time.
“LSD? Who, me??? How dare you think it? I was just being a devoted father - taking an interest in the child everyone knows I neglect terribly. Yeah. We were playing with crayons and drawing pictures and I was totally sober like the exemplary parent I am.”
So interesting... an intriguing new set of questions... so cool... thanks for the update about Lucy
Super interessting! Thank you very much wonderful Aton!
Yuuus awesome stuff, Thanks Anton
i'm ethiopian and watch all your videos, thanks for the really cool fun fact!! 🇪🇹🇪🇹
Thank you for this great video! I wonder if the simplest explanation for Dinkinesh's double moon is simply the YORP effect again. When the moon broke off from the main body and was spun off to its current orbit, maybe the differential heating made the moon start spinning as well, and it broke in half. The two halves didn't have enough angular momentum to get far away from each other, so gravity gradually drew them back together again until they touched.
I always loved the name of that effect
It makes me laugh every time I see it
What a great lead up to the intro! Fantastic
Your best intro to date, imho, and a great episode in any case 👍❤
Stay wonderful everyone 🖖
Thank you wonderful Anton It is so great to explore the unknown universe with you and not even leave home
That was the best segue I've ever seen you wonderful wonderful person!
Anton thank you for such a great job. Love your work.
Great video, very interesting information, thanks
Best "wonderful person" intro ever Anton
Thanks Anton...!! You have, easily, one of the best science channels...!! ✌ 🇨🇦
Thanks for the great information you provide and your keeping it simple for guys like me. I have always been interested in space and love watching the stars above. Keep up the great work and again thanks 🙂👍👍🖖
Considering the loose nature of the parent body, it wouldn’t take much energy to sling material off the surface, so when it had enough angular momentum to tear itself apart, the material probably formed a wide ring system for some time, with material at the outer edge rotating more slowly than at the inner edge, which would lead to the body that would coalesce on the inside repeatedly overtaking its outer sibling, pulling it up to speed while bleeding off a little energy, until they had exchanged enough momentum to begin orbiting one another, their surfaces eventually making contact.
I would anticipate if we were able to look back at this system at some point in the distant future, we will find two round bodies, as the binary moonlet is composed of the same loose rubble as the parent, which will allow it/them to change shape over time and condense into a single body.
I don't know how I found Anton but so glad I did.
Great content Anton . It looks like an object is moving in the top left corner of the Orus time lapse video. Thoughts
Keep creating these informative videos!
Thanks for sharing
Wonderful stuff ^^
Thanks for another fun video. Cheers from the Pacific West Coast of Canada.
Really fun and interesting video, as usual! :)
Any news on the family planning front?🤞
Anton why have we had no updates on the Mysterious Spherical Object spotted by Hayabusa on the Itokawa Asteroid?
The long intro was worth the wait!
Every lucky now and then I log on just as Anton has released a video.
Your videos are so interesting
thank you Anton 😊 ❤
Cool video thanks
I'm curious if there is some reason that the mass shedding that produces binary asteroids stops at binary? Does some interaction between the two bodies prevent further mass shedding by one or both? If not then the old ones should do it multiple times and produce their own little cloud of moonlets.
Hello wonderful Anton.
Can not praise this man enough for his videos!
I’m not wonderful, you are wonderful Anton .
Love the 4.5 min intro
I'd like to see a mission to Mar's, Trojan and/or Greek asteroid(s). To see if they might help in future terraforming efforts of Mars. If even in a minor way, like possibly having water under it's surface or for items that might be able to be mined to help with efforts of terraforming Mars.
You need to make a Dinkinesh t-shirt Anton!!! I would absolutely buy that! It would be so adorable! I already have one of your shirts, pleeez!!!! 🙏 ❤
great intro!
thank you.. liked and shared
Anton...we saw what you did with the term "Dinkinesh"...and we appreciate it!
Yay ! Great news ! Thank you !!
'Lucy' looks more like a vampire than a satellite.
Anton perhaps the Lucy space craft was named after one of the oldest known human ancestors, but a quick google, says she was in turn named because they "nicknamed the skeleton “Lucy” after the Beatles song “Lucy in the Sky with Diamonds,” which was played at the celebration the day she was found." being named after “Lucy in the Sky with Diamonds" is perhaps more appropriate but it does refer to LSD
Fascinating stuff indeed!
That is so cool that Lucy's indigenous name means Wonderful Person!
Nice intro wonderful person
Another great job Anton ! I do wonder if Lucy has of its own propulsion? for when it gets to the L3/4 postions, how does avoid collisions or is it the case the density of Asteroids in that region is not that dense etc? Makes you wonder in the future we will likely be mining all those areas probably likely the Jupiter lagrange points id guess so interesting.
LUCY does have propulsion. In fact, she has couple of engines of different power. Though they are all rather small and meant for maneuvering and course corrections, not long sustained burns. That's why gravity slingshots will be the main method of reaching her targets.
The asteroids in that region (and also in every other region in the solar system) are not dense at all. It doesn't look like it is shown in lots of scifi movies.
Anton I was wondering, how much MASS does an object need to hold onto an atmosphere? Is it impossible for a Trojan or non-planet sized object to have one?
Apparently, any body less than 2.7% the mass of the Earth does not hold on to a 'habitable' atmosphere. I obviously had to look this up, I'm relatively stupid; the information was from the Harvard Gazette. As for an atmosphere, I got totally lost in the supportable mists of the theorising. More interesting for now, than the speculative answers, is the question. It's a damn good question NosuRRenDDeR001!
At its most basic, for an object to have a permanent atmosphere (as opposed to something tenuous that is continuously stripped away, like the gas surrounding a comet) it has to have a high enough escape velocity to recapture gas molecules moving at whatever temperature the upper atmosphere is at. For most gases, that's pretty darned fast. For something like nitrogen molecules at the distance of Jupiter, the rms speed of the molecules is ~375 m/s. That is much, much more than the escape velocity of any but the largest asteroids (literally just Ceres and Vesta). For an asteroid like Dinkinesh, the escape velocity is only ~1/2 m/s. If you were on its surface it would be extremely difficult to not wind up flying away. (Value figured assuming Dinkinesh to be a 400m radius sphere with density 3000 kg/m3, which is probably an overestimate.) There are other important factors that make retaining a permanent atmosphere difficult, like the solar wind, but just as a starting point, escape velocity will prevent any asteroid from holding on to gas permanently.
It's quite impossible, because it gets stripped away by solar winds. The further you are from the sun, the smaller you have to be to hold on to gas, but the required mass is still orders of magnitude above asteroids. Maybe an astrophysicist could give us a best-case scenario, if we are lucky.
Depends on where and the conditions of the object really. The solar winds are going to be harsher near us than pluto. Then there's if it's magnetic enough to act as a plasma barrier.
Let's take Ganymede for example. Larger than Mercury, has no atmosphere. Where as Titan, a smaller Saturn moon but still 50% larger than our moon, has a dense atmosphere with liquids on the surface. Then there's tiny Pluto, which is 1/3rd smaller than our moon, and only has an atmosphere when it's closer to the sun than Neptune. While Mars and Mercury are having their atmospheres blasted off by the Sun.
Is " atmosphere " strictly defined as external to the planet or object?
Mind suitably amazed and boggled
Love to see You smile брат.
This is so cool!
A well played introduction
4:15 hello wonderful people haha😂 that was the perfect set up
Politicians: won't even consider planning more than a couple years ahead.
NASA: casually running missions that last over a decade.
Interesting,exciting, nice, thanks 👍😊
I look forward to your video in 10 years
I like the intro. The news were a bonus
I vote they name the next dwarf planet discovered after Anton. It's the least we can do for this wonderful person 🤗
best intro on this channel
