Study shows our sun is less active than similar stars

By cosmic standards the sun is extraordinarily monotonous. This is the result of a study presented by researchers from the Max Planck Institute for Solar System Research in the upcoming issue of Science. For the first time, ...

Fast reconnection in turbulent media

Solar flares, similar to many other astrophysical energetic processes, are related to magnetic reconnection. During these events magnetic energy is transferred from other forms of energy, mostly heat and energetic particles. ...

A new theory of magnetar formation

Magnetars are neutron stars endowed with the strongest magnetic fields observed in the universe, but their origin remains controversial. In a study published in Science Advances, a team of scientists from CEA, Saclay, the ...

Solar storms may leave gray whales blind and stranded

A new study reported in the journal Current Biology on February 24 offers some of the first evidence that gray whales might depend on a magnetic sense to find their way through the ocean. This evidence comes from the discovery ...

First Solar Orbiter instrument sends measurements

First measurements by a Solar Orbiter science instrument reached the ground on Thursday 13 February providing a confirmation to the international science teams that the magnetometer on board is in good health following a ...

Ten things we've learned about the sun from NASA's SDO this decade

In February 2020, NASA's Solar Dynamics Observatory—SDO—is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the sun, studying how the sun creates solar activity and drives ...
