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.
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.
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 record-breaking field was discovered at the surface of a neutron star called GRO J1008-57 with a magnetic field strength of approximately 1 BILLION Tesla. For comparison, the Earth’s magnetic field is about 1/20,000 of a Tesla.
The South Atlantic Anomaly is a vast expanse of reduced magnetic intensity in Earth's magnetic field, extending all the way from South America to southwest Africa.
Astronomers spotted a magnetic explosion on the surface of the sun unlike anything they've ever seen before. Although it was initially theorized about 15 years ago, this was their first direct observation of it thanks to NASA's Solar Dynamics Observatory.
Mercury is now the second rocky planet—after Earth—for which we have evidence of a solid inner core. It’s not an exact value, but the mere presence of a solid inner core helps to understand how the planet generates its magnetic field.
Scientists have found that the magnetic north pole is moving at a speed of about 55 km every year. A hundred years ago, the pole was located near the coast of northern Canada. Now, it is in the middle of the Arctic Ocean.
The international research team found that magnetic field reversals could happen much more rapidly than the thousands of years previously thought to be needed.
