Our Sun has been quite active over the past several weeks, ejecting giant strands of stellar debris into the cosmos. NASA scientists recently captured a video of one particularly eye-catching explosion that produced a dramatic arch across the sun’s surface.
Our sun may look relatively constant from our far away perch on Earth, but up close it's a busy place, full of plasma activity, shifting magnetic fields, and, yes, even explosions. Here are the different kinds of solar explosions you might see, and how to tell the difference between them.
Aurora are beautiful, but the fire and smoke of Bárðarbunga step it up to gorgeous. The weekend kicked off with the Earth putting on a glorious display of green, blue, purple, and red, and countless photographers braved varied terrain to capture the ephemeral light for your viewing pleasure.
The sun fired off an X-class solar flare, the most powerful classification, this afternoon, from an Earth-facing sunspot called Active Region 2158. The flare was powerful enough to cause a sustained blackout of high-frequency radio communication here on Earth.
NASA's sun-observing IRIS spacecraft has gotten its first close-up look at a colossal coronal mass ejection erupting from the sun, and boy howdy is it beautiful.
Yesterday morning, the sun unleashed a powerful X1 solar flare. X-flares are the most powerful classification of solar eruption there is. This is the latest in a string of recent outbursts, with yesterday's eruption among the most violent we've seen all year.
So this is unexpected. The Sun is currently at the peak of its 11-year solar cycle. It should be awash with sunspots, solar flares, coronal mass ejections and the like. And yet, observations indicate our parent star has actually been pretty quiet this year – so quiet, in fact, this year's solar max could go down as…
With all the exciting solar activity lately, NASA’s Goddard Space Flight Center shared this helpful tutorial about the vocabulary of space weather on their Facebook page. Now you can tell your CMEs apart from your solar flares.
In less than 24 hours, the Sun has unleashed a trio of X-Class solar flares. They are the first, second and third X-class eruptions of 2013, making them the most powerful of the year by a substantial margin. What's more, each burst has been more violent than the last. So uhh... what the hell is going on here?
Photographer Göran Strand used 2464 raw images taken with his all-sky camera to create this gorgeous time-lapse video. The swirling crystal ball images show the view from Östersund, Sweden, when a when a Coronal Mass Ejection hit Earth’s magnetic field.
On Tuesday night, the surface of the Sun erupted in an violent solar flare, blasting a massive wave of charged particles in the direction of Earth. And early this morning, those particles smashed into our planet's atmosphere.
