The sun is on the verge of a significant event: a magnetic field reversal. What causes this switch in polarity, and is it dangerous for anything on Earth? Let's take a deep dive into the phenomenon of ...

The Sun’s magnetic poles are in the middle of an uneven, drawn-out reversal as Solar Cycle 25 moves through its solar maximum phase. NASA and NOAA jointly announced that the current cycle has entered ...

Magnetic field reversal is a fascinating topic. You are brought up to think that the compass, pointing to the north, is an infallible instrument, and then you find out that the magnetic pole moves, ...

Massive solar flares, graceful eruptions of solar material, and an enormous sunspot make up some of the imagery captured by NASA's Solar Dynamics Observatory in 2013 and 2014. A year ago this weekend, ...

Much of the Sun's tempestuous nature comes from its core. At its core is dense, electrically charged gas. Electrically charged gas is a special form of matter called a plasma. This roiling, boiling ...

After causing the dazzling waves of aurora borealis this weekend, our Sun isn't done yet: The strongest solar flare of the current solar cycle occurred Tuesday afternoon, according to the National ...
