NASA has released 30 minutes of the most amazing, high-resolution video footage of the sun ever. DNews points out some key events visible on our gassy friend in the sky.
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.'
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.
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.
Julian gives a primer on sunspots -- what causes them, how often they happen, and most importantly: whether or not an enormous one is set to fire straight at Earth.
Eruptions on the sun's surface are probably caused by giant, unstable magnetic plasma arches, a new study reports — a discovery that brings scientists one step closer to predicting solar outbursts that can wreak havoc on Earth.
A huge arc of plasma has been imaged rising from the sun's surface by a NASA solar observatory, producing a beautiful view of the sun's magnetic dynamics in action. Continue reading →
