'Raise shields!' may be a familiar defensive order given in the Star Trek Universe, but according to space scientists in our Universe, Planet Earth has its own built-in invisible shield that buffers 'killer electrons' from orbital altitudes.
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.
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.
Just as the US prepares to watch the partial solar eclipse today, nearly 100 million miles away on the sun a possible solar storm is brewing. Continue reading →
The question as to where the majority of moon water came from isn't so straightforward -- it was actually 'baked' via reactions with the solar wind. Continue reading →
New research suggests a plasma bubble in the high atmosphere blocked radio communications during a 2002 firefight in Afghanistan, which lead to a deadly US helicopter ambush.
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 →
Over the past 24 hours, our planet's global magnetic field has been bombarded by two coronal mass ejections (CMEs) and now, as predicted, a "strong" geomagnetic storm is underway. Continue reading →
