#Earth's magnetic field is weakening 10 times faster than originally predicted, swarm satellites show

#Earth's magnetic field is weakening 10 times faster than originally predicted, swarm satellites show | The limitless universe | Scoop.it

Earth's magnetic field, which protects the planet from huge blasts of deadly solar radiation, has been weakening over the past six months, according to data collected by a European Space Agency (ESA) satellite array called Swarm.

 

The biggest weak spots in the magnetic field — which extends 370,000 miles (600,000 kilometers) above the planet's surface — have sprung up over the Western Hemisphere, while the field has strengthened over areas like the southern Indian Ocean, according to the magnetometers onboard the Swarm satellites — three separate satellites floating in tandem.

 

The scientists who conducted the study are still unsure why the magnetic field is weakening, but one likely reason is that Earth's magnetic poles are getting ready to flip, said Rune Floberghagen, the ESA's Swarm mission manager. In fact, the data suggest magnetic north is moving toward Siberia.

 

In fact over the past 20 million years, our planet has settled into a pattern of a pole reversal about every 200,000 to 300,000 years; as of 2012, however, it has been more than twice that long since the last reversal. These reversals aren't split-second flips, and instead occur over hundreds or thousands of years. During this lengthy stint, the magnetic poles start to wander away from the region around the spin poles (the axis around which our planet spins), and eventually end up switched around, according to Cornell University astronomers.

Green Fly Geyser in the Nevada Desert - The Geothermal Accident wow!

Green Fly Geyser in the Nevada Desert - The Geothermal Accident wow! | The limitless universe | Scoop.it

Mother Nature didn’t create this geothermal wonder, but neither did aliens. In 1916, a rancher drilled a well in hopes of turning the desert into a fertile wetland, but accidentally hit a geothermal pocket of water. It wasn’t until 1964 that boiling water started to escape to the surface and that is how this geothermal wonder came to be. It’s located on private property, the Fly Ranch. This phenomena has been named Fly Geyser in the Black Rock Desert of Nevada, located about 20 miles north of Gerlach.

 

The sits upon a sludge and dirt platform and is surrounded by terraces of warm water ponds which have spread to 30 – 40 pools over 74 acres. The geyser has continuously grown since the 1960s. It constantly spews hot water about five feet into the air which can been seen from miles away. The three green and red massive rock pillars that are 10 to 12-foot calcium carbonate cones – actually they are only about 3 feet tall, but the added height is due to the mounds they sit on. The red and green coloring on Fly Geyser is caused by thermophilic algae. Fish were added to warm pools surrounding the Fly Geyser and birds come there too creating a new ecosystem in a desert habitat.
