Earth's Magnetic Field Almost Completely Collapsed 550 Million Years Ago

Image
More than half a billion years ago, Earth experienced a near-complete collapse of its magnetic field. It begins in the early Cambrian period. Then, after a period of about 15 million years, the field began to grow again. The cause of the collapse and the reflection of the field is a mystery. Then, a group of geologists studied the rocks from Oklahoma that formed during that time. Magnetic markers in rock minerals point to events that began about 550 million years ago. That was before multicellular life was introduced on our planet. Look Deep Into The Core To understand what’s going on, look at the structure of our planet. Most of us learned in school that the Earth is made up of layers. There’s a crust, where you’re sitting reading this now. Beneath it is the mantle, the thickest layer of the earth. It lies above the molten outer core, which surrounds the solid inner core. The inner core has two parts—the outermost inner core and the innermost core. The cor...

Cell phone providers selling customer service they can't use, says ombudsman

Image
Cell phone service providers fail to provide adequate coverage and sell consumer products they cannot use, according to the Telecommunications Industry Ombudsman. Key points: Ombudsman received 63,000 complaints about mobile phones in two years People are left without phone coverage during emergencies Help services operated by online bots and automation are not suitable for all customers A report released today shows cell phone complaints to the ombudsman’s office have surged over the past two years despite a decline in the overall number of complaints. The office received 63,000 complaints about cell phones during the period. The report details examples of people trapped without cell phone service in emergencies. “People come in with an idea of ​​what they think they want and they’re selling a product they may not want, need or understand,” says Telecommunications Industry Ombudsman Cynthia Gebert. Several people living in high-risk emergency areas told the ombu...

The massive hydrothermal field 8,366 feet below the surface of the Pacific Ocean resembles a candlestick

Image
Scientists discovered a new hydrothermal field 8,366 feet beneath the Pacific Ocean covering an area the size of a football field that could help them better understand how volcanic activity has affected life in Earth’s oceans. These deep-sea vents are located in places where activity from the planet’s crust causes tectonic plates to split and form new seafloor rock that contains cracks where seawater seeps – similar to what hot springs do on land, these vents eject mineral-rich fluids. heated to a high temperature. A team of researchers from Lehigh University discovered this field about 200 miles off the coast of Mexico and have stated that it will help to advance our understanding of how marine life is – and continues to be – affected by volcanic eruptions. Scroll down for the video ‘The mapping work provides a detailed picture of the ocean floor so we can monitor and measure changes that occur when the next volcanic eruption occurs,’ said one of th...

Monster Hydrothermal Field Found in the Dark Depths of the Eastern Pacific

Image
The large field of hydrothermal vents on the seafloor in the dark depths of the East Pacific ocean is the hottest and largest ever found in the region. Not only that, but in places where scientists don’t expect to find active vents, let alone the entire system, hundreds of meters from the axis of the volcanic ridge. The discovery, scientists say, could have a significant impact on our understanding of ventilation systems, and the role they play in marine ecosystems. The field was discovered by a team of scientists using autonomous underwater vehicles to map the ocean floor at depths inhospitable to human explorers. In the data obtained from the AUV. Woods Hole Oceanographic Institution Security the team looked at the region of the massive tower, standing three stories high at 2,560 (8,400 feet) meters below the surface – in permanently dark and silent bathypelagic depths. Ventilation is monitored with a temperature recorder. (WHOI/NDSF/ROV Jason/NSF) Initially, the team thought ...

Astronomers Have Seen A Record-Breaking Magnetic Field In Space, And It's Incredible

Deep in the Milky Way, roughly 22,000 light-years from Earth, a star unlike any other roars with a magnetic force that beats anything physicists have ever seen. With 1.6 billion Tesla, a pulsar called Swift J0243.6+6124 broke the previous record of around 1 billion Tesla, found in the vicinity of pulsars GRO J1008-57 and 1A 0535+262. For a little context, your average new fridge magnet comes in at around 0.001 Tesla. More powerful MRI machines manage to reach around 3 Tesla. A few years ago, engineers were credited with hitting the semi-respectable 1,200 Tesla, keeping it in a flash of just 100 microseconds. So it makes sense that 1.6 billion Tesla would demand some truly amazing physics. The kind that can only be achieved by massive objects crammed into impossible volumes and spinning at incredible speeds, fast enough to accelerate electrons to ridiculous speeds. Swift J0243.6+6124 is already considered a noteworthy star. A type of super-compact cosmic heavyweight known as a pulsar...

James Packer joins ex-wife Erica and Ayda Field at Saint-Tropez

Image
Billionaire James Packer has backed up his recent claim of being the happiest in years with a warm public hug from ex-wife Erica, mother of three. Having lost more than 30 kg and stopped taking the drugs that took so long to change his mood, Packer seems to have forgotten the series of problems behind him. The 54-year-old, who recently sold his stake in Crown Resorts for $3.3 billion, said he was ready to embark on the ‘third act’ of his life and plans to return to his hometown of Sydney. On Wednesday he showed his newfound satisfaction when he joined 44-year-old Erica for a holiday in Saint-Tropez. The former couple, who have remained best friends after their split nearly a decade ago, were spotted docking their yacht at the world-famous beachside restaurant Club 55. James Packer looked happier than ever when he joined his ex-wife Erica for a holiday in Saint-Tropez on Wednesday. In a rare public display of affection for the former couple, who split in 2013, Packer ...
