Oumuamua, an asteroid.
People run in different directions in search of bunkers and underground shelters, dozens of planes take off to defend the Earth, all because our sensors have detected an extra terrestrial civilization ship and our solar system, breathe a sigh of relief.
It’s only an asteroid.
Those shaped like a spacecraft. And it’s the first interstellar object to be discovered in our solar system in history.
It’s called OUMUAMUA. This object came in here from the deep interstellar space.
It has an elongated shape and is about half a mile long.
It’s bigger than Eiffel Tower.
And it was moving toward the centre of our solar system at about 31 miles per second, and kept accelerating at that speed, you can cross the Atlantic Ocean in less than two minutes.
Our scientists speculated for a moment that it could have been a spaceship of extraterrestrial civilization in decided to check it out.
Normal spaceships and other human made objects he met radio waves for communication.
So the scientists use breakthrough listen radio telescopes in Australia, in the United States to try to receive a signal from the interstellar object, and not the complete silence.
Of course many speculate that the radio silence is not a clear proof that this isn’t a spaceship, but all the evidence points to it being an asteroid after all, although it’s been travelling in our solar system since about 1995 Our scientists spotted it and 2017 after it flew in a critical distance from the earth.
So one astronomical unit is the distance from Earth to the Sun. Oh moolah moolah approached Earth at a distance of 0.1 astronomical units.
If more and more had hit Earth, the consequences would have been catastrophic.
The energy, the asteroid had is its velocity squared multiplied by its mass.
Since we know its speed, scientists needed to determine the second component in here.
They made another discovery, our only option was to observe the asteroid from afar with telescopes, and we can figure out its weight,
not by putting it on a scale,
but by understanding what kind of light is reflected.
for example, iron reflects certain types of light waves,
while cool reflects others,
and that’s where scientists realised that oh moolah moolah is constantly flashing the light first slowly fades away,
and almost completely disappears, then the asteroid starts to be bright again.
It means that a OUMUAMUA is spinning,
but it doesn’t do this like an arrow,
rotating around its axis,
the asteroid also spins horizontally,
and it’s front and rear ends rise up and down this chaotic motion made scientists think that more and more was brought here by some incredible force from interstellar space.
That kind of rotation would have torn the asteroid apart,
but it’s still intact,
which means it’s mostly made of solid rock,
and maybe even iron.
So if a more and more had hit the ground would have created a crater the size of a city in the blast wave would have destroyed everything around it for hundreds or 1000s of miles.
The sound of the incident would have been heard,
even on other continents.
Fortunately, a more and more flew past her,
and continued its acceleration toward the sun at its closest point to our star,
the asteroid reached its maximum speed 54 miles per second at that speed,
you would travel around the earth in just seven minutes,
but only the gravitational pull of the Sun couldn’t give this debris that speed.
Normally, comets can accelerate even faster because of the rocket effect.
The sun heats up the comment and light elements there begin to evaporate as they evaporate one way they push the comet the other way,
like a rocket.
And it’s because of these elements that we can see the comments long bright tail with butthole moolah moolah has no tail.
So this speed was given to it originally in the place where it was born.
Some people speculate that OMO Moy used to have a tail when it entered our solar system,
there was a huge layer of nitrogen ice over the years.
This ice melted and evaporated, this accelerated the asteroid and created a huge tail behind it,
but then the ice, which was 95% of the asteroids total weight, ran out and all that was left was this long,
narrow wreckage that was discovered years later.
Well, scientists can neither confirm nor deny this theory.
Warm approach to the sun from about point 25 astronomical units,
when this is closer than the orbit of the first planet near the Sun, Mercury,
the asteroid then fell into the stars gravitational trap around in flew out Slingshot is now heading toward the constellation Pegasus.
So scientists believe that more and more was born from a dramatic collision of an exoplanet somewhere in another star system with another massive object.
As a result of the explosion. A huge narrow fragment was ejected into outer space.
And for this reason,
It continues to spin mad with this traumatic event could also have been a supernova explosion.
Such explosions occur when a star, ages,
it runs out of fuel inside itself and shrinks for a split second,
and then a powerful bright explosion is visible for light years around the blast wave from a supernova could rip some exoplanets into small pieces.
One of them is a more or more,
or perhaps this asteroid came to us from the birth of a new star.
First, there was a nebula. It was heavy and shrank around a common centre of gravity. When the nebulas core became too compressed,
it exploded in the asteroids in cosmic debris burst into different directions,
scientists were considering sending a space probe to the surface of OUMUAMUA,
we could study the interstellar body and use the asteroid as a taxi to other worlds,
flying to other stars with existing technology and rocket engines would take an incredible amount of time and feel.
If we ride an asteroid,
just like a horse.
It could do the job for us.
One option was to use a probe with a sail,
then instead of traditional rocket engine.
The Pro would be propelled by solar wind or a powerful laser.
this concept would involve launching about 1000 probes,
each weighing less than a sewing needle,
and each of them would be attached by cables with a light sail as big as a boxing ring,
then ground lasers will focus their beams on the sail and allow the armada of probes to accelerate to 20% of the speed of light.
That’s the speed needed to catch up with the asteroid as it leaves the solar system.
Scientists thought we could use a gravitational manoeuvre around Jupiter to reach that speed in a conventional spacecraft.
But we never made the launch,
and it’s too late to catch up with OUMUAMUA.
Right now, it’s heading toward the edge of our solar system and will soon leave in forever.
A woman who was the first object to visit our solar system that we can observe and study,
but there have been such guests here before.
There’s a theory that about 70,000 years ago,
we were visited not by a meteorite,
but by the double star system shows us star in approach the Oort cloud.
This is such a wall of asteroids space debris and blocks of ice far at the edge of our solar system,
the stars gravitational field began to trap this debris,
and throw it toward the sun.
This may have been the reason for the frequent meteorite impacts on Earth’s surface at that time,
the stars gravitational field shook up the planets orbits in the solar system of it.
If the star had continued toward the sun.
It’s likely that this world would have been gradually destroyed planet by planet,
and it would have ended with the sun colliding with this red dwarf,
followed by a massive explosion. Fortunately,
the ropes are only barely touched the border of our world and continued its journey in the other direction.
But we’re waiting for a new guest from interstellar space.
The star Gliese 710 Right now it’s moving toward our solar system at 32,000 miles per hour,
that’s twice as fast as our rockets can go as Gleason approaches the Oort cloud,
it’ll start throwing asteroids in our direction,
gas giants like Jupiter will intercept most meteorites,
but every day about 170 meteorites of various sizes and shapes will fall to Earth,
that is 10 times more than what is falling on our planet.
Now, you already know all the following consequences.
But the arrival of Glee 710 Won’t happen for at least 1.2 million years.
So exhale with relief and look at the first interstellar object made by humanity.
The Voyager space probe.
Two of these probes were launched 44 years ago when they’re still operational,
Voyager One was the first space probe in history to cross the heliosphere, the boundary of our world where the solar wind stops blowing.
So this probe essentially carries the title Interstellar.
Perhaps many years from now,
Voyager One will enter another star system and say hello to a possible civilization like ours that lives there.
To that end, both Voyagers are equipped with gold plates with a methods for other civilizations, their slides of Earth landscapes recordings of human speech, our DNA, and many more things.
