A Crack Appears In the Sun

This photo, taken last week by NASA's Solar Dynamics Observatory (SDO), shows a "filament" of cooler solar material hovering over the surface of the sun. The effect is of a huge crack across the sun, as if something is preparing to burst out. » 2/17/15 11:30pm 2/17/15 11:30pm

The Solar Dynamics Observatory Has Captured 100 Million Sun Images

On January 19th, NASA's Solar Dynamics Observatory (SDO) released its 100 millionth image of the sun. This image is a processed multiwavelength blend made from the images taken on the 19th to honor the milestone. » 1/21/15 12:30am 1/21/15 12:30am

The Sun Is Beautiful When Its Magnetic Field Is Angry

These huge coronal loops reach out more than fifteen times the diameter of the Earth, tracing out disruptions in the sun's magnetic field. Whoa. » 10/20/14 1:00am 10/20/14 1:00am

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

What Would An Eclipse Look Like From Right Next To The Sun?

Just what does a solar observatory in orbit see when the moon moves right between it and the sun? These pictures of a partial eclipse of the sun, from way, way up close, answer that question. » 7/29/14 9:40am 7/29/14 9:40am

The Sun Emits a Plasma Arc So Big You Could Fit 25 Earths Beneath It

The sun is big. Really, really big. It's so big, every feature on it is mind-boggling huge. Last week it spun out a massive prominence arcing out into space so ginormous that a mischievous fireproof Titan could've used it as a hoop to dunk the Earth in a game of cosmic basketball. » 7/22/14 7:31pm 7/22/14 7:31pm

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

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

How the hell is this photo of the Moon even possible?

Can we all just sit and marvel at this ridiculous shot of the Moon for a second? Because that would be great. Seriously, people. Just look at it. » 4/30/13 12:20pm 4/30/13 12:20pm

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

Observing the Sun through this gradient filter is like nothing you've…

The last time you heard the term "gradient filter," it was probably in reference to a feature on a photo editing program, but scientists studying images and video collected by NASA's Solar Dynamics Observatory use gradient filters, too — often with absolutely mesmerizing results. » 10/19/12 8:10am 10/19/12 8:10am

This is the most spectacular solar flare we've seen in ages

Earlier this afternoon, magnetic fields on the Sun's northeastern limb exploded in an arcing jet of roiling plasma, producing what is hands down one of the most spectacular solar explosions we've seen in years. » 4/16/12 3:30pm 4/16/12 3:30pm

You've never seen a solar eclipse quite like this

This morning, at 9:47 am ET, the Moon passed in front of NASA's Solar Dynamics Observatory, temporarily blocking the satellite's view of the Sun. Fortunately for all of us, the Observatory's cameras were rolling — and what it captured is an incredible sight to behold. » 2/21/12 3:37pm 2/21/12 3:37pm
