Here Are All the Different Ways the Sun Can Explode

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. » 9/22/14 11:31am 9/22/14 11:31am

Mesmerizing Aurora in Dramatic Landscapes of Fire, Ice, and Shadow

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. » 9/12/14 11:53pm 9/12/14 11:53pm

An X-Class Flare Unleashed Right At Earth

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. » 9/10/14 7:00pm 9/10/14 7:00pm

NASA Observes A Solar Explosion In Unprecedented Detail

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. » 5/31/14 5:00pm 5/31/14 5:00pm

Our Sun Emits One of the Most Violent Solar Flares This Year

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. » 11/20/13 9:20am 11/20/13 9:20am

2013's solar maximum could be weakest since the dawn of the space age

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… » 7/12/13 1:20pm 7/12/13 1:20pm

Become fluent in the vocabulary of solar flares and space weather

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. » 5/15/13 8:20am 5/15/13 8:20am

What the hell is happening on the Sun?

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? » 5/14/13 8:15am 5/14/13 8:15am

Watch four hours of Aurora Borealis compressed into three stunning…

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. » 3/24/13 1:00pm 3/24/13 1:00pm

Watch this stunning solar eruption create loops of fiery rain on the…

This is incredible. NASA has just released a never-before-seen video of a solar eruption from July of last year that shows a solar flare, a coronal mass ejection, and loops of solar rain all occurring in one breathtaking sequence. » 2/21/13 6:40am 2/21/13 6:40am

A huge coronal mass ejection slammed into Earth today

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. » 3/08/12 8:00am 3/08/12 8:00am
