It is. That's That's the Younger Dryas boundary. And I'm with Alan West, who's one of the scientists from the from the comet research group who are working on the Younger Dryas hypothesis. And our hands are on that black stripe runningthrough the middle of the draw. And that is soot. That is evidence of wildfires burning.
And then the minute you start talking about humanoid robots and robotics, which I think is basically going to hit society like a comet , like a meteor. I think the the first humanoid robot from Tesla or anyone else that is highly effective in the realworld at doing tasks and is extremely intelligent cuz it's powered by one of these LLMs,
your body acts a little bit different under extended periods of weightlessness so if you're looking for gifts for the holidays vomit Comet that's on my wish list one of these days low low price of $6,000 yeah little little little more attainablethan the mission to Mars billions it's all relative that billion all right so adding to your cool Factor you get to
been, you know, if there's a planet, right? You're not going to discover a planet with your telescope. So you read his writings and it says a peculiar comet . This is it refuses to show a tail or a fuzzy sort of coma around the soit's it's a it's a it's a it's a misbehaving comet when in fact he had discovered a planet. All right. Then it
One thing here to remember is compare the pictures of the comet here that are in this VR video, which is before we got there to what they actually turned out to be like. -Comets are really important. They're like a time capsule back to our past.
They're not like the solar system was 4 and 1/2 billion years ago. Comets actually enable us to look back into what the solar system was like over four billion years ago.And the way we do that is we have to go and find these comets .
You see much more of it called 67P Churyumov-Gerasimenko. Comets are named for the people that discover them, so it's unfortunate that Bob Smith didn't discover this one.It's just a long name, but these two Ukrainian astronomers discovered it in 1969.
So we get to-- after that, we turn this the spacecraft off, spin it up, and pray. Comets don't live forever.
very large planet or of a sun, they start to break up into multiple parts, and this is what happened to the Younger Dryas comet . Instead of being a single bullet, it became a shotgun blast. It became thousands and thousands of objects, of which we've cataloged quite a lot. Numbers of them, comet Encke is the best known bit of that
objects, of which we've cataloged quite a lot. Numbers of them, comet Encke is the best known bit of that former comet . Many of the academics who look at this think that comet Encke, which is about 6 km in diameter and which does cross the orbit of the Earth, they think that that was the source comet . But whereas the other team are
beginning of Younger Dryas? It shouldn't have happened. The comet theory explains it perfectly. The the the mass, the impact, the heat, the air bursts, that would have been enough to send the ice sheets into
If you find a comet , it's all yours. A comet Lintott, I think-- I still think-- has an excellent ring to it. I never found a comet .
I gather what it's about is they sent basically miners to space. The comet is still rotating in space.
I gather what it's about is they sent basically miners to space. the comet reacts to the sun, which is very important, because we don't really know how comets react to the sun.
I gather what it's about is they sent basically miners to space. A comet is constantly changing.
That's the comet going through. The comet 's on a six and a half year orbit. We didn't miss it.
"Stop taking this so seriously. The comet is coming.
If it wasn't on the surface shortly after the birth of the solar system, was it delivered from somewhere else later on? And comets could be a very important vector for that, because they lock up ice and dust in the outer solar system. And those objects and then come into the inner solar system through perturbations and impact on the planets.
We were going to this comet , 67P Churyumov-Gerasimenko, as I said. Most comets , many comets are in an elliptical orbit. 67P goes out beyond the orbit of Jupiter.
Second challenge was to then figure out, how do you maximize the sunlight hitting the arrays without But comets also pose hazard as well.
Because, you know, our ancestors were just little basically rodents, rats living under the footsteps of the dinosaurs. And it was that comet impact that opened the route for us. I mean, that still took another, you know, 65 million years.
orbit around the sun. This would be a comet of the diameter of 100 km, maybe 200. Comes in, gets captured by the sun's gravity, goes into an orbit. That orbit crosses the orbit of the earth.
But man, I remember-- I made "Comet " when I was 35. I didn't make a lot of money off of that.
And this is a dust tail. As the comet approaches near the Sun, the matter gets ionized. And so these two tails are very different properties.
If you discover an asteroid, you have to name it after somebody else. If you find a comet , it's all yours. A comet Lintott, I think-- I still think-- has an excellent ring to it.
A comet Lintott, I think-- I still think-- has an excellent ring to it. I never found a comet . I did spend ages with a small telescope looking at something called the Orion nebula.
I gather what it's about is they sent basically miners to space. And that was their comet samples.
I gather what it's about is they sent basically miners to space. It behaves like a comet .
I gather what it's about is they sent basically miners to space. One side collected comet particles and then the back side collected interstellar particles.
I gather what it's about is they sent basically miners to space. to get to its comet .
I gather what it's about is they sent basically miners to space. So this comet called 67P Churyumov-Gerasimenko.
I gather what it's about is they sent basically miners to space. It got to the comet and it basically had to do a power-- it couldn't get into orbit around it because this object is small.
I gather what it's about is they sent basically miners to space. So the comet is not attracting that thing to it.
I gather what it's about is they sent basically miners to space. We notice that the comet had different seasons on it depending on where you were on the comet and where it was in relation to the sun.
And the Portuguese-- chiles to India. Maybe a comet brought it all the earth in the first place. Who knows? Oh, I quite agree with Dr. Mitra.' He plucked a lemon from a tree.
The very formidable-looking woman at the telescope here is Mariah Mitchell, who was the first American woman who really became famous as an astronomer because she discovered a comet in 1847. And the young woman, Antonia Maury, was Henry Draper's niece.
it's is it physiologically different in other words when you're weightless in the space station are there different physiological effects than when you're in the vomit Comet for that little window of time it's so it's the same feeling but the physiological effects I I think become problematic when you're in that period for a a longer period than 30 seconds there's a lot of fluid
How do we know what our original solar system was made out of? Does the comet really represent some of that original material? And it's so very different.
Coming into the Earth would be a very bad thing for all of us. We have this comet that's only 50, 60 years been coming in and having all of these volatiles burnt off of it. This is a great target for us to get to visit.
But before that, we flew flybys of about two kilometers. Orbiting a changing comet environment, and I'll tell a little bit of the story about how the spacecraft saved one time when we flew too closely.
Recall earlier in the video, I showed you this round, mostly spherical object. The actual comet turned out to be a contact binary. We can see it here.
You actually build a tumble model from the periodic current data from the solar panels. You mentioned the comet itself is about four kilometers in diameter or some equivalent of that. And then the orbiter was orbiting at a distance like 10 kilometers on average?
looks like a comet in the sky.
of that comet -like tail.
And you'll see when we get further out, we go to asteroid Lutetia. That's the comet going through. The comet 's on a six and a half year orbit.
If you know Comet Holley, it used to be called Halley's Comet .
"Stop taking this so seriously. that the comet is coming anymore.
"Stop taking this so seriously. When the comet is coming, you can't save the entire human race.
And they caught this comet on September the 11th, 1985.
It encountered the comet Halley, but at about 21 million kilometers.
