EXPLAINED! Strange image of the sun ‘SMILING’ captured by The NASA Solar Dynamics Observatory SDO

A NASA observatory caught what seemed like a jack-o'-lantern smile on the sun's surface, but were really splotches on the sun's surface that are colder than the surrounding regions.

Last week, NASA posted a picture of the sun captured by its Solar Dynamics Observatory. The image sparked a flood of comments offering explanations on the image's pattern of irregular black spots.

While NASA's official Twitter account referred to it as a "smiling" sun, the Science and Technology Facilities Council of the United Kingdom photoshopped a pumpkin into the image, converting the sun into a jack-o'-lantern.

Various users saw animals like lions and blobfish, as well as snack snacks emblazoned with happy grins.

However, the space agency reports that the dark regions leading to the face pattern are really coronal holes, which appear as uneven black patches when the sun is shown in ultraviolet light or certain kinds of X-ray imaging.

Since coronal holes are cooler and less dense than their surroundings, they seem darker. There's no telling when they'll make an appearance on the Sun's surface.

Because of the way their magnetic fields are shaped, coronal holes are able to open and spew forth charged particles from the sun at speeds of over a million miles per hour (1.6 million kilometres per hour). The force of these winds is sufficient to reach Earth. While the protective magnetic field of Earth deflects most solar wind, even this little exposure may cause atmospheric disturbances.

The NASA Solar Dynamics Observatory, or SDO, takes such pictures of the sun on the regular and watches its activities virtually nonstop. The space agency's Living With a Star Program sent the observatory into orbit in 2010, with the goal of studying the effects of the sun on Earth and the interstellar medium.

I think sun is just getting ready for Halloween.

Sun: you've never seen a pumpkin this hot? Happy Halloween my favorite planet!

It looks like it was bitten by Mr. Frundles.

the sun smiles at you with eternal malice

Bout to be hit with "When Day Breaks"

[gazzacroy]

this thing still amazes me it's massive, millions of miles away and can still burn you. wow just blows my mind :)

[sonnychavez]

The first thought that came to mind was Teletubbies

[JeevanSamagar]

Even though it can disturb the atmosphere

[nitram]

What a great intellectual contribution to science !

[ettygfryhfth]

The sun face is similar to solar ball channel

[bazpearce]

The SDO websie is amazing. 15 different views of the Sun almost 24/7/365. Apart from the odd eclipse.

It looks like the Stay-Puff Marshmallow Man.

Say cheese! 📸

Today, NASA’s Solar Dynamics Observatory caught the Sun "smiling." Seen in ultraviolet light, these dark patches on the Sun are known as coronal holes and are regions where fast solar wind gushes out into space.

So it is nice and won’t explode us sometime in future

[rickyb]

It's probably getting ready to burn earth.

Wouldn't you enjoy a little schadenfreude watching all the bonkers nonsense going on from a healthy 150 million kilometer distance? 😸
