00:00Increase the rate of time to thousands of years per second.

00:17And taking us along for the ride.

00:21By feeding Gaia's data into computer models, scientists can simulate the past, present, and future.

00:45The outer part of the solar system that we call the Oort Cloud.

00:50It's this leftover debris from when the solar system formed.

00:55Lots and lots, millions and millions of comets.

00:58Maybe even some asteroids that are out there.

01:01And what we were going to show is dynamic interactions that might happen between our Oort Cloud and other stars' Oort Clouds.

01:10As everything is in motion and stars pass by each other.

01:13Now, as we were modeling the Oort Cloud, we turned to one of the world's leading experts on modeling it.

01:22His name is David Nisvorni.

01:24He gave us his simulation.

01:26And we were looking at it inside of the planetarium just to get an idea of how to make it beautiful for the show.

01:32And we played with how bright all the particles were.

01:35And we immediately saw something that we had never seen before.

01:40That no one had ever seen before.

01:43It was a spiral structure in this Oort Cloud.

01:48Now, this Oort Cloud is a simulation of what we think it looks like.

01:52But it's based on real data of objects we have measured in the outer part of our solar system.

01:59So, when we saw it, we were blown away.

02:02It was a spiral shape, almost looking like a galaxy itself.

02:08But it's shaped by the forces of the galaxy itself.

02:13Of what we call the tidal force of the galaxy.

02:17So, this spiral structure was brand new.

02:22And we immediately wrote up a paper for an astrophysical journal.

02:27And it's now a published part of astronomers' knowledge of what the outer part of our solar system looks like.

02:37And it all came from visualizing data for the American Museum of Natural History's new space show, Encounters in the Milky Way.

02:44I'm Pedro Pascal.

02:47Join me on a journey, through our tight-knit, stellar neighborhood, into the bustling metropolis of the Milky Way.

02:58We'll witness some of the chance encounters that have shaped the destiny of our Sun.

03:04And maybe even the course of life in the cosmos.

03:08On our travels, we can expect to pass through bubbles, again and again.

03:16Because the galaxy is peppered with massive stars that go out in a blaze.

03:21We're all in a journey around the Milky Way galaxy.

03:22And you can still see the next galaxy are in a blaze.

03:23So, here's the galaxy, and this is the galaxy, and this is the galaxy, and this is the galaxy.

03:24y deslizando de deslizando de shockwaves.

03:44Aunque cada pasada de un camino es unico,

03:46todos estamos en un viaje en la galaxia del milky way.

03:50Para nosotros, para nuestro sistema solar y el sol,

03:57una órbita va a necesitar 230 millones de años para completar.

04:03¿Ves el Big Dipper?

04:07Veamos mientras aumentamos la cantidad de tiempo a miles de años.

04:20Conocer a la tecnología, los científicos pueden simular el pasado, el presente y el futuro de nuestra 200 millones de años.

04:40Algunos clústeres miran a una gran estructura, 1000 años de luz.

04:49Es un deslizamiento dentro de las luces de gas y deslizamiento.

04:56Nos llamamos la local bubble.

05:04Nuestro sistema solar está ahora dentro del deslizamiento.

05:11Esto es por lo que los científicos de las luces de las luces de las luces de las luces de las luces.

05:18Gracias por ver el video.

05:25La cuestión es que es un combiante de la notación que estamos viendo reales ciencias,

05:50Pero we're putting that together

05:52In ways with the explanation

05:54Seeing how things

05:56Behave at these vast scales

05:58Seeing our, again, our relationship

06:01To it

06:02And we have to keep that thread

06:04And then

06:06Drawing that together

06:07As, you know, a pacing and a story

06:11That's really told within

06:12A limited time

06:13We put the music score to it

06:16And Robert's music, as I say

06:18Really gives it wings

06:20And that, in the end

06:22The show aspect

06:23Is something that you feel here

06:26At best, if we can pull that off

06:42The stars

06:43We say they're beautiful

06:45We say the flowers are beautiful

06:48Or a landscape

06:49Why that's beautiful

06:51Is because I think we do react

06:54To it on a level

06:55That's emotional

06:58And it reminds us

07:00Of our place

07:02In a much grander realm

07:04And the stars, ultimately so

07:06I mean, for so much

07:08Of human existence

07:09We didn't know

07:10Whether they might just be

07:11Ten feet above our heads

07:12But there's something

07:16That echoes

07:18The periodicity of the sky

07:20And, you know, it was

07:22Our notion of a clock

07:23Is based on our diurnal

07:25Repetitive nature

07:27And all this

07:28But you look at the stars

07:29You're looking at light

07:32It's coming to you

07:33The sun is too bright

07:34To look at

07:35But there's something

07:37Almost hinting at

07:38That these are other suns

07:40Perhaps

07:40And then that light

07:43That links us

07:44When we figured out

07:47That that's traveling

07:48At a set amount of time

07:49You can look at the

07:52You can look out

07:54At the stars

07:55And you're looking back

07:56Into time

07:57And you're looking back

07:58Into the times of lives

08:00You're looking at light

08:01That's arriving

08:02From different epochs

08:04And different periods

08:05And you can say

08:06You know

08:07A deceased relative

08:09Or what have you

08:10You're seeing light

08:11That really

08:12Is still part

08:13Of their time

08:15That's where it gets

08:20Kind of spiritual

08:21And, you know

08:24And that's real

08:27And that's, you know

08:29Is what

08:30I think

08:31Holds us together

08:33Really
