It's not what is causing the image you are looking at but it is worth remembering

Two light beams going in opposite directions move away from each other at twice the speed of light when viewed side on you would conclude that.

Nothing in that defies the laws of relativity ... no single object is moving faster than the speed of light.

Think about the angle you have on the event as shown.

It is also true that in a fast expanding universe the two edges of the universe can be moving away from each other at faster than the speed of light for exactly the same reason as the opposite light beams above.

Paul, why are you posting optical illusions? This isn't an optical illusion. You can see the shape how it really is. You can reorient it if you like, and maybe it'll look more like a dimple than a blob, but the same would be true of the other ones.

Mt point is, those sun blobs from NASA are consistent with compression artifacts. The problem is most people don't understand the technology they're using enough to recognize a compression artifact.

but wouldn't the compression artefact's be found throughout the images if it is a algorithm issue?

as in the below image.




and why would ESA and NASA put such a crappy camera system on a billion euro venture in the first place
when the results / images taken by the camera would be a major component of the project's success?

also , if it is an algorithm problem then they should change the algorithm to reflect a little quality and just have a bit more patience waiting the extra second for the images to process.

of course if this was a planned issue then the low quality images makes perfect sense to me.

after all its not a project to find extraterrestrial life
is it.

its a project used to observe the sun.

so why would you need quality images?

Remember they're supposed to be caused by cosmic rays, which would illuminate a single pixel extremely brightly without necessarily affecting its immediate neighbors. Something that pretty much no ordinary scene would do, not even an actual blob. You example picture doesn't show how JPEG fails to cope with sharp points.

I guess one way to solve it would be have the onboard computer check for these things and take another picture immediately after. But then people would complain that it's censoring things!

It's not the camera, it's the compression. They already resolved it by getting higher quality versions of the exact same images after they fixed one of the receiving stations on Earth. Those new images show the small points as much more like small points.

I guess you'd be happy if they just shut everything down when there's a failure, rather than trying to squeeze whatever data they can from it.

Exactly. But if it does happen to pick up actual objects (who said anything about life?), then they'll look like objects, and won't be explainable as cosmic rays with compression artifacts.
