NASA Searches For And Finds Portals In Earth’s Magnetic Field

A portal is basically a short-cut that takes the user through space, and even time, to other realms or places. Portals were always  believed to be imaginary devices though; a quick explanation for why the protagonist is able to access fantastical lands…. Because portals.

It turns out that portals do exist, sort of, and a NASA-funded researcher at the University of Iowa has figured out how to find them.

“We call them X-points or electron diffusion regions,” explains plasma physicist Jack Scudder of the University of Iowa. “They’re places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun’s atmosphere 93 million miles away.” Ah, so the term “portal” in this case is merely a corridor between the Earth and the Sun that allows the transmission of particles between the two spheres? How boring.

Observations by NASA’s THEMIS spacecraft and Europe’s Cluster probes suggest that these magnetic portals open and close dozens of times each day. They’re typically located a few tens of thousands of kilometers from Earth where the geomagnetic field meets the onrushing solar wind. Most portals are small and short-lived; others are yawning, vast, and sustained. Tons of energetic particles can flow through the openings, heating Earth’s upper atmosphere, sparking geomagnetic storms, and igniting bright polar auroras. OK, so it’s not completely boring.

NASA is planning a mission called “MMS,” short for Magnetospheric Multiscale Mission, due to launch in 2014, to study the phenomenon. Bristling with energetic particle detectors and magnetic sensors, the four spacecraft of MMS will spread out in Earth’s magnetosphere and surround the portals to observe how they work.

“Unfortunately, magnetic portals are invisible, unstable, and elusive. They open and close without warning “and there are no signposts to guide us in,” notes Scudder. Scudder apparently proves himself wrong by finding these signposts.

Portals form via the process of magnetic reconnection. Mingling lines of magnetic force from the sun and Earth criss-cross and join to create the openings. “X-points” are where the criss-cross takes place. The sudden joining of magnetic fields can propel jets of charged particles from the X-point, creating an “electron diffusion region.”

To learn how to pinpoint these events, Scudder looked at data from a space probe that orbited Earth more than 10 years ago.

“In the late 1990s, NASA’s Polar spacecraft spent years in Earth’s magnetosphere,” explains Scudder, “and it encountered many X-points during its mission.

Because Polar carried sensors similar to those of MMS, Scudder decided to see how an X-point looked to Polar. “Using Polar data, we have found five simple combinations of magnetic field and energetic particle measurements that tell us when we’ve come across an X-point or an electron diffusion region. A single spacecraft, properly instrumented, can make these measurements.”

This means that single member of the MMS constellation using the diagnostics can find a portal and alert other members of the constellation. Mission planners long thought that MMS might have to spend a year or so learning to find portals before it could study them. Scudder’s work short cuts the process, allowing MMS to get to work without delay.

It’s a shortcut not quite worthy of those found in fiction, but hey. At least these portals are real. And with the new “signposts” we know how to find them.

  1. Hey fellas, personally I reckon that as long as people know Where and when they are travelling to, time and space travel sounds fucking awesome, but that being said I would much rather know that people are travelling to reasonably safe locations, doesn’t have to be anything special, but I don’t like the idea that decent people might be travelling to a war zone let alone the constant prescience of satan in hell.

  2. There is no short way to heaven.This is actually an underworld they are trying to open.This is the most evil thing going on on the planet.You better be ready spiritually!

  3. There is no shirt way to heaven.Thats what they want you to believe.They are opening up hell itself.You better be ready spiritually!God is the only one that’s gonna help us.Sad they are doing this and hiding it.CERN these pool are evil.They think they are gods.
