Stunning animation shows how our planet protects us from solar wind

The process that forms Earth’s first line of defence against killer solar storms has been revealed for the first time.

In a groundbreaking study four NASA spacecraft observed a process known as magnetic reconnection, which is the planet’s first line of defence against the intensity of the solar wind.

It occurred in a turbulent region of the Earth’s outer atmosphere known as the magnetosheath, and could radically change what we know about protecting the planet, and future astronauts.

Dr Jonathan Eastwood, from the Department of Physics at Imperial College London, who worked on the study, said: ‘Turbulence is one of the last great concepts in classical physics that we do not understand well, but we know it’s important in space as it redistributes energy.

‘With this observation, we can now make new theories or models that will help us understand observations of other places like the Sun’s atmosphere and the magnetic environments of other planets.’

Magnetic reconnection has been observed innumerable times in the magnetosphere — the magnetic environment around Earth — but usually under calm conditions.

The new event occurred in a region called the magnetosheath, just outside the outer boundary of the magnetosphere, where the solar wind is extremely turbulent.

The mission, known as Magnetospheric Multiscale (MMS), was commissioned to study magnetic reconnection, a common event throughout the universe that occurs when magnetic fields change by connecting and then breaking apart.

It found a new breed of magnetic reconnection, known as electron magnetic reconnection, that is much different than the kind that happens in the much less turbulent magnetosphere closer to Earth.

Previously, scientists didn’t know if reconnection even could occur there, as the plasma is highly chaotic in that region.

MMS found it does, but on scales much smaller than previous spacecraft could probe.

The new insights could help us understand how such phenomena affect Earth’s atmosphere because of the potential impact on astronauts in space, satellites and electrical power industries.

‘The turbulence in the magnetosheath contains a lot of magnetic energy,’ said Tai Phan, lead author of the Nature article and senior fellow in the Space Sciences Laboratory at the University of California at Berkeley.

People have been debating how this energy is dissipated and magnetic reconnection is one of the possible processes.’

The energy comes directly from the sun’s corona, a blazing hot environment that shoots particles out in all directions at speeds around 1 million miles per hour.

This is the forceful solar wind.

When its power hits the magnetosheath, waves of plasma chaos roll through it.

Scientists don’t know yet how all of that turbulent energy is dissipated.

As magnetic field lines cross, intense electric currents (shown here as bright regions) form and eventually trigger magnetic reconnection (indicated by a flash)

But this new discovery – electron magnetic reconnection – may help them learn more.

The MMS mission has four spacecraft flying in formation about four miles apart, gathering data as they go.

Its array of instruments gave researchers one of their first opportunities to search for reconnection in the magnetosheath.

They got what they hoped to get – evidence th

But in the process, they discovered magnetic reconnection here works much differently than the kind observed elsewhere.

Instead of huge jets of ionized hydrogen atoms, triggered by many collisions of magnetic fields, this form of magnetic reconnection shoots off much tinier electron jets with very few collisions occurring, Shay said.

This has never been recognized before, partly because no instruments could capture the process.

The relative difference in size between the electrons and the ions is similar to the difference between ball bearings and basketballs, Shay said.

The electrons are harder to spot, and moving 40 times faster.

‘I had simulated this possible kind of reconnection,’ Shay said.

‘But no one had ever observed it happening in space.’

The analysis could reveal many more surprises as scientists continue to explore the data MMS has sent.

‘MMS has taken us to a whole new level,’ Shay said.

‘It’s like knowing about atoms and then finding out about even tinier parts like the nucleus or the electrons.

‘People were not expecting it.’

This Is The BIGGEST Mystery Found By Accident…

Description:

It’s kind of amazing that we’re sitting here in the year 2018, yet new discoveries about the planet still manage to surface every day. Some include newly undiscovered places or animals that no one has ever seen or documented before. And that is exactly what we’re talking about here today on Top 5 Supreme. Today’s video is called This is the Biggest Discovery Found By Accident! So sit back, relax, and prepare learn something new today! Before we get started with today’s video don’t forget to click the bell to get notified every single day with the best Top’s you’ll ever see. Also, don’t forget to subscribe to this channel. So let’s get rolling!

#5 Large Skull

Imagine having your own farm and one day discovering that your land is the exactly location where an ancient animal lost his life? That’s exactly what happened to this soy bean farmer in Michigan. James Bristle made this crazy discovery recently. One day he saw something sticking out of the ground. On first thought, he imagine it was probably some time of fence post. But, it wasn’t. After getting a team to dig deeper into the land he found out that his land was the proud owner of an ancient wooly mammoth skull that was completely intact! This animal lived here 15000 years ago. Wow.

#4 Potato Chips

So, how many of you love to eat potato chips? I expect to see everyone’s hand raised right now, by the way. Anyway who knew that potato ships were actually an accidental creation? In 1853 a chef in New York accidentally created the tasty treat when an annoying customer kept sending back his French fries because they were too soggy. So the chef, in an attempt to be funny, sliced his next batch of potatoes extra thin and drowned them in salt. To the chefs surprise though, the customer actually loved the new creation. And thus, potato chips were born! Pretty cool huh? Actually, I’m pretty hungry and could go for some chips right now. Oh, never mind. Moving on.

#3 Weird Wishes

Around 50 years ago a farmer in china wanted to build a new well on his land. So, he sat out with the proper tools and began digging into the ground. However instead of finding water, he found something pretty crazy, and kinda cool. What he found was over 80,000 – yes, I said 80,000 – perfectly preserved statues of ancient generals and warriors. It turned out to be the burial sight of an ancient general, and the fact that all of these were found relatively unharmed is a sign that he was a general of great distinction and respect. One more cool fact is that the general was only 13 years old when he ordered the construction of the statue army. 13!

#2 Voynich Manuscript

The Voynich Manuscript is one of the most bizarre discoveries ever made. The codex, or book, is written in some kind of alien code that not one person has been able to decipher. Found in 1912, it was discovered that the book was actually written in the 15th century. The contents of the book are pretty crazy – otherworldly animals, alien coding and nude women doing all sorts of crazy stuff can be found throughout it. The book is so unusual that the language that was used to fill the book is still yet to be deciphered. The scientists and researchers who’ve studied the writings within are all stumped to this day, leading some to believe that the entire thing is just a hoax. But, for what purpose? Others believe it was dropped here, a long, long time ago, by some kind of alien beings. Whatever it is, here’s to hoping that the writings are deciphered sooner than later.

#1 $2M Penny

How much are the pennies in your pocket worth? Probably just 1 cent. Like normal. But what if I told you about a penny that was actually worth about $2 million? Check this out. Robert Lawrence was the son of a guy that worked in the US mint. After his father passed Robert took over his coin collection that was just sitting in a little sandwich bag. One of the pennies in the bag – an all aluminum penny that was only 1 of 10 ever made – was originally believed to be worth about $300. But after a little more research it was actually discovered that it was worth $2M. That’s crazy!
