A giant eruption from the sun that scientists thought would hit Earth in 2014 missed because the sun's magnetic field channeled it away from the planet in an unexpected way.
Astronomers studying stars like our sun that are known to generate powerful 'superflares' have also discovered that these superflares are likely associated with monster 'starspots.'
After a long period of calm, the sun awoke from its slumber and erupted with one of the most powerful solar flares of the year on Tuesday.
This image isn't a close-up from the garden, but an active area of strong magnetic fields on the sun's chromosphere.
Jan. 19, 2015, was a red letter day for NASA's Solar Dynamics Observatory -- one of its instruments, having continually stared at the sun for 5 years, captured its 100 millionth observation of our nearest star.
A machine on Earth capable of recreating the conditions inside the sun's heart is helping scientists study how iron behaves at mind-boggling temperatures. The results of the experiment, so far, have defied expectations and just might help settle a long-standing solar puzzle.
NASA's Nuclear Spectroscopic Telescope Array has turned its gaze from distant black holes and focused on our sun, producing the most sensitive measurement of high-energy solar X-rays ever achieved.
There was already a high probability that active region (AR) 2192 was going to erupt with a powerful solar flare, so it came as little surprise when two X-class flares erupted within 24 hours of eachother.
