Watch the sun exploding in glorious 1080p HD

A beautiful NASA video of coronal rain.

NASA has released an astonishing video of a solar flare erupting on surface of the sun. Crack open something to drink, put on some suitably epic music, whack this full screen and sit back and gaze:

The video was taken over the course of 21 hours on July 19 last year, and shows first a solar flare, erupting from the lower right hand "limb" of the Sun. Then, a coronal mass ejection sprays some of that material deep out into space. And finally, "coronal rain" starts dropping the bulk of the matter back onto the sun's surface.

Slate's Bad Astronomy describes what caused it:

The gas inside the Sun is so hot it’s ionized, stripped of electrons. When that happens it’s more beholden to magnetism than gravity, and when the magnetic field lines pierce the Sun’s surface they form loops along which the ionized gas (called plasma) flows along them.

The bright flare happens when the stored magnetic energy erupts outward, usually due to what is essentially a short-circuit in the field. That happens near the beginning of the video, and is so bright it saturates SDO’s detectors (and you can see repeated ghost images to the upper left and right of the flare as the light reflects inside SDO’s optics). Then things settle down, and that’s when the beauty really begins: The plasma flows down the loops, raining down onto the Sun’s surface.

The coronal mass ejections — CMEs — can sometimes be aimed directly at Earth. When a small one hits, it causes aurorae in the far north and south, but larger ones can cause power outages and affect satellites.

The art of the YouTube Poop

What are YouTube Poops and why do we need them now, more than ever?

“The world today doesn't make sense, so why should I paint pictures that do?”

So, allegedly, said Pablo Picasso in a shrewd attempt to justify his love of putting noses where noses don’t actually go. It is imperative that you now hold this profound quotation firmly in your mind whilst you watch this four minutes and 57 second long clip of Arthur – the cartoon aardvark – being tormented by squirrels.

What you have just seen is an example of the art form primarily known as “YouTube Poop” (YTP). Beginning in the early Noughties, this cultural movement is characterised by confusing and shocking edits of Saturday-morning cartoons, video games, and viral videos. Though the Tens have seen the genre decline in popularity, the YTP is, nonetheless, one of the defining innovations of our era.

Those in the Poop community don’t actually like being labelled as artists, as one Yale student found out when he attempted to define them as such on the University’s technology blog. Though they have been compared to Dadaism, YTPs are more vile, violent, and most importantly, nonsensical than most artworks, but this is precisely why they are an asset to our age. In a world where – sorry Pablo, you got nothing on us – absolutely zero things makes sense, it is time for the YTP to have a comeback.

Despite its seeming randomness, the world of YTP is not without its rules. “Poopisms” are the common techniques and tricks used in videos to ensure they qualify as a true Poop. They include “stutter loops” (the repetition of clips over and over), “staredowns” (freezing the frame on a particular facial expression), and the questionably-named “ear rape” (suddenly increasing the volume to shock the viewer). One of the most humorous techniques is “sentence mixing”: forcing characters to say new sentences by cutting and splicing things they have said.

There are also firm rules about what not to do. Panning across a clip without adding another Poopism at the same time is considered boring, whilst using your own voice to dub clips is seen as amateur. By far the biggest barrier that Poopers* face in creating their videos, however, is the law.

Despite what many eight-year-olds on YouTube think, declaring that something is a “parody” in the description of a video does not make it exempt from copyright laws. The video below – regarded by at least two commenters as “the best YouTube Poop” ever – is missing audio 20 minutes in, as the creator was hit by a copyright claim.

Yet even the iron fist of the law cannot truly stop Poopers, who are still going (relatively) strong after the first YTP was created in 2004. YouTube Poops now even have their own Wikipedia page, as well as a page on TV Tropes and a WikiHow guide on how to create them, and for good measure, avoid them.

YouTube Poops have therefore undoubtedly secured their place in history, and whilst you might wander into a comment section to declare “What have I just watched?”, remember that Pablo Picasso once said: “The purpose of art is washing the dust of daily life off our souls.” He almost definitely wasn’t talking about “You are a Sad Strange Little Man” by cartoonlover98, but still.

* The term “Poopists” was rejected by the community for being “too arty”.
