It always makes for a beautiful video whenever the suns lashes out with a solar flare. Here’s one from earlier this month, you can see how electric its movement are, it just whips up and explodes. The footage was captured in different wavelengths and then color coded so we can see what’s happening in better detail. In…
At first, things could actually be rather beautiful: worldwide auroras! A brighter sun! But then things would rapidly get ugly, with the breakdown of communications, rolling power outages, and a burning away of the ozone.
We all know that major storms can wreak havoc, flooding cities and decimating infrastructure. But there’s an even bigger worry than wind and rain: space weather. If a massive solar storm hit us, our technology would be wiped out. The entire planet could go dark.
NASA’s Solar Dynamics Observatory captured an image of a mid-level solar flare that pealed at 4:16 EDT this morning. It comes from the sunspot group that’s been flaring up since it was spotted.
A solar flare peaked at 7:28 p.m. EST on December 19, and the NASA's Solar Dynamics Observatory caught this image of it. It was classified as X1.8-class. X-classes are the most intense flares, with an X-2 being twice as strong as an X-1.
The sun is spoiling us for superlatives. Last night, giant sunspot AR 2192 – the largest sunspot astronomers have observed in nearly 25 years – erupted in an X3.1-class solar flare, the most powerful of four flares to burst from the region since October 19th.
Last week, a solar flare flashed on the surface of the sun, just as our star erupted with a massive amount of burning ejecta. The twin explosions, captured by a NASA satellite called the Solar Dynamics Observatory, make for a gorgeous and violent portrait of our sun.
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.
Last week, NASA announced that in 2012 the Earth narrowly avoided being hit by the largest solar coronal mass ejection recorded since before electric power grids and telecommunication satellites were a thing. Fortunately or unfortunately, along with the rest of civilization, the solar crisis duology Cat. 8…
A massive solar storm in July 2012 was more intense than thought—and it blasted right through the Earth's orbit. Luckily for us, we were on the other side of the sun, thus missing the chaos completely. But if that storm had hit this beautiful little blue marble in space? "The solar bursts would have enveloped Earth in…
Nope, that's not lens flare you're seeing. That's a solar flare — an insanely large, extremely bright solar flare.
Late last month, NASA's Interface Region Imaging Spectrograph (aka IRIS) witnessed the strongest solar flare it's glimpsed since its launch last year.
Millions of charged particles are rushing toward earth after a gigantic solar flare on Tuesday. Bad news for NASA's latest mission, but good news for sky-watchers: Those charged particles also collide with the earth's atmosphere to produce the ethereal-looking northern lights.
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.
On April 11, 2013, at 3:16 a.m. EDT, the sun emitted an M6.5 flare, allowing NASA to capture this vibrant image. It's not a particularly powerful solar flare, but it is the strongest of 2013 so far, and we'll have plenty more opportunities to observe solar activity this year.
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.
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.
The Sun is nearing the pinnacle of its 11-year cycle of solar activity, which means things have been pretty wild on the surface of our resident star. As the cycle approaches peak activity (scheduled to climax this year), solar flares like the double eruption observed just this morning are expected to increase in both…
