The Cosmic Megaflares That Could Hit Earth | How The Universe Works

The universe is a magnetic minefield. Our own Sun spits out spectacular flares, capable of battering life on Earth. But out there in deep space lie the true magnetic monsters... As we uncover the most dangerous megaflares in the cosmos, the question is, will we find Earth in the firing line?

How The Universe Works reveals our grand understanding of the universe using the latest research, the most compelling experts, and the best graphics to continue our exploration of the mysteries of the universe.

The Universe has had a *long* time to extinguish life on Earth, if it were so inclined. Apparently it is not, as we are still here.

considering the current hell on earth as a result of the presence of human beings, what's there to loose?

I don't mind because I no longer want to go to work.

The first mega flaring star in this episode is a relatively rare breed of flare star called a flash flare or flash shine star.
They can brighten up to hundreds of times brighter than usual.

I am certainly not an expert but I believe hydrogen bombs and atomic bombs are two different types of critters.

The second model of the magnetars is the scariest model of a magnetar ever known.
The magnetars visible electromagnetic sounds makes them sound scarier than previously thought.

The season 2 magnetar animation can also be used to show what’s left behind after a neutron star collision.

Shoutout to the camera man for going to the sun

Red dwarf mega flares are also another way to find red dwarf stars that are too far away to be seen by powerful telescopes.
Red dwarfs can also be some of the fastest spinning non dead stars in the universe, some can spin up to one rotation every few hours.

I was looking for this episode, in order to understand how scary Magnetars are?
This Magnetar is called SGR 1806-20, it’s this Magnetar that have effected the earth 50 thousand light years from Earth.
The good news is that when magnetars die out(after a thousand to 500 thousand years), they will die out for good, even if they are rejuvenated by a companion star.
When magnetars become vampires after they die out, will be reverted back into pulsars.
Magnetars formation is the most mysterious question.
And it turns out that they are actually turbo charged neutron stars that have been amplified by a companion star.
Mainly another neutron star that has turbocharged the other stars magnetic field exponentially.
Or maybe more likely a collision between a white dwarf star or through multiple red dwarf interactions.

Very interesting indeed.
What would make it more serious?
Change the narrator with another, but serious narrator, that doesn't sound like an American wrestling or "Highway through Hell" commentator..

Make Morgan Freeman do it

"Is earth in danger?". Yes, but not from any interstellar threats

1st comment from mauritius. I have one conclusion to make, the only reason earth will be destroyed will not be because of cosmic blasts, supernovas or fallen comets but because of the accumulated amount of sins of human being around the world that's it.

Changing the title of a documentary and posting it again doesn't make it new.

Imagine your government making people go homeless, because of a carbon tax 😢

[unnikrishnannairkrishnannair.]

Traveling magnetic fields can burn uor homes wth its crossing our electic lines

Sweden and you and world Liège girig and

Sorry, gamma-ray's are faster than light.

the sun will engulf the earth, yet people are worried about plastic bags and straws 👌
