Deep beneath our feet, in the heart of our planet, something unexpected is happening. Scientists have discovered that Earth’s inner core, a solid iron-nickel sphere roughly the size of the moon, is slowing down.
Geoscientists show that rocks from the Isua Supracrustal Belt in West Greenland have experienced three thermal events throughout their geological history.
Earth's magnetic field nearly collapsed some 590 million years ago, presumably putting life on the planet's surface at risk of a rise in cosmic radiation.
Rocks that formed some 3.7 billion years ago in the early Archean have given us the earliest glimpse yet of Earth's magnetic field.
A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organised magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*).
Made some 3,000 years ago, the Mesopotamian bricks contain grains of iron oxide that, to the right interpreter, reveal fascinating changes in the magnetic field that runs through and envelops Earth in a protective barrier.
The location of the north magnetic pole has moved by about 965 kilometers since the first measurement was taken in 1831. This could indicate the beginning of a field reversal, but scientists really can’t tell with less than 200 years of data.
Astronomers detected the most distant galactic magnetic field so far. The galaxy is called 9io9. Its light has to travel travel more than 11 billion years to reach us, from a time when the universe was a young 2.5 billion years old.
Data collected by the BepiColombo spacecraft traces the causes of the strange aurora, which course through the planet's weak magnetosphere.
In a new research scientists observed a repeating fast radio burst for more than a year and discovered signs it is surrounded by a strong but highly changeable magnetic field.
The South Atlantic Anomaly is growing, according to data that appeared in a government report published earlier this year.
One of the most common sources of magnetic fields on large scales comes from the collisions between and within interstellar plasma. This is one of the major sources of magnetic fields for galactic-scale magnetic fields.
At the Chinese Academy of Sciences' Steady High Magnetic Field Facility, a magnet years in development achieved a steady magnetic field of 45.22 tesla – tens of thousands of times more powerful than an souvenir fridge magnet.
The enhanced growth on one side of the core suggests that something in Earth’s outer core or mantle under Indonesia is removing heat from the inner core at a faster rate than on the opposite side, under Brazil.
The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light.
