Earth's inner core is slowing down, making our days a bit longer

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.

Earliest Evidence of Earth's Magnetic Field Found in Greenland

Geoscientists show that rocks from the Isua Supracrustal Belt in West Greenland have experienced three thermal events throughout their geological history.

Life Blossomed When Earth's Magnetic Field Nearly Collapsed 590 Million Years Ago

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.

Ancient Rocks Reveal Earth's Magnetic Field Existed 3.7 Billion Years Ago

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.

Strong magnetic fields spiraling at the edge of Milky Way's central black hole

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*).

Ancient Mesopotamian Bricks Captured a Blip in Earth's Magnetic Field

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.

Earth's Magnetic Field Could Be on The Verge of Flipping Over

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.

Most distant galactic magnetic field yet

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.

Mercury appears to have its own aurora

Data collected by the BepiColombo spacecraft traces the causes of the strange aurora, which course through the planet's weak magnetosphere.

Surprise Magnetic Signal May Finally Solve The Mystery of Fast Radio Bursts

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.

Mysterious Anomaly in Earth's Magnetic Field is Deepening

The South Atlantic Anomaly is growing, according to data that appeared in a government report published earlier this year.

Largest Magnetic Fields in The Universe

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.

World Record For The Most Powerful Stable Magnetic Field

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.

Earth core is lopsided

  • 16 Jun 2021

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. 

Image Of A Black Hole With A Magnetic Field

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.
