After three years of collecting data, Swarm mission scientists have produced the highest resolution map of Earth’s lithospheric magnetic field from space to date. The dataset combines measurements from ESA’s Swarm satellites with historical data from the…
Scientists at the Earth-Life Science Institute at the Tokyo Institute of Technology reported in Nature yesterday their unexpected discoveries about the Earth's core. The findings include insights into the source of energy driving the Earth's magnetic field,…
Earth’s magnetic field is crucial for our existence, as it shields the life on our planet’s surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth’s core. Iron is a metal, which means it can easily conduct a flow
NASA’s Goddard Space Flight Center’s visualization studio made an amazing video of Sun using a gradient filter which highlighted the details of the sun’s complex magnetic fields. Gradient filter helps researchers in better understanding how solar activity affects
On February 10th there was filament eruption in the northern hemisphere that produced CME which traveled few days before reaching our magnetosphere on February 14. As magnetic disturbance rippled around the Arctic circle on February 14th, it opened a crack in our
A minor solar wind stream is buffeting Earth’s magnetic field. Arctic sky watchers should be alert for auroras.Solar windspeed: 469.1 km/secdensity: 2.3 protons/cm3The Radio Sun10.7 cm flux: 135 sfuPlanetary K-indexNow: Kp= 1 quiet24-hr max: Kp=
Active region 1319 contains many individual sunspots. The swarm is growing. Over the weekend, the sunspot group's total area nearly tripled as shown in this movie from the Solar Dynamics Observatory:
As AR1319 has grown, the complexity of its magnetic field
A comet discovered by amateur astronomers on Friday, Sept. 30th, disintegrated in spectacular fashion the very next day when it plunged into the sun. The Solar and Heliospheric Observatory recorded the comet’s last hours. The end was punctuated by an unexpected
On October 1st around 10:17 UT, widely-spaced sunspots 1302 and 1305 erupted in quick succession, revealing a long-distance entanglement which was not obvious before. NASA’s Solar Dynamics Observatory (SDO) recorded the movie of the double blast:Since it was
A CME hit Earth’s magnetic field on Sept. 26th, sparking one of the strongest magnetic storms in years. At the peak of the Kp=8 disturbance, auroras were sighted around both poles and more than half a dozen US states. Magnetic reverberations continued for more than 48
