Comment[edit]

Can somebody who is more knowledgeable please visit this article? Specifically, could somebody please elaborate on what happens to a Granule after dissipating? I’ve heard different explanations, so I’d be nice to get more information on that process.

As the granule dissipates, it radiates energy in a spherical manner, as the energy below is superior, the energy is largely emitted outward. Then, consternation sets in, as the sun also has a massive magnetic field, which confuses things. During quite times, a significant amount of the energy is emitted outward. In a magnetic tangle, things get more confused. Sunspot time is... Erm, complex beyond imagination. Think that supercomputers have to try to figure it out, with human computations and learn every day/month/year.Wzrd1 (talk) 06:27, 26 December 2014 (UTC)[reply]

Image inaccuracy[edit]

I noticed this image that attempts to show the scale of a granule:

This image seems to imply that The United States is less than 1000 kilometers wide. This is wildly inaccurate, as the approx. width of The United States is ~ 4313 kilometers. Clearly, the two items given for scale on the image don't match up, so my next question was which was superimposed scale image was inaccurate, the scale bar or the image of The United States? Looking at the image information at Wikimedia commons, it states that it is a derivative work from a NASA image. Doing a google image search for "Photospheric Granulation G. Scharmer Swedish Vacuum Solar Telescope", I found this NASA image.

Looking at this, it seems the Wikipedia image is a small part of a larger image (vertically center, horizontally right of center), and judging from the scale bar on the original image, the answer to my question of 'which scale comparison is inaccurate', it seems the answer is: Both! And the image is even more inaccurate than initially suspected, as 1000 km should take up approx. the width of the entire image.

I propose replacing this image entirely. Presumably we can just replace it with the NASA image at https://solarscience.msfc.nasa.gov/images/granules.jpg using the same argument/logic surrounding the copyright laws as the image we are replacing used. Or maybe not... Perhaps the image is property of the Swedish Vacuum Solar Telescope. Anybody know? How to tell? Thoughts on replacing this? Thanks.

Move discussion in progress[edit]

There is a move discussion in progress on Talk:Spicule (solar physics) which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 22:19, 19 February 2022 (UTC)[reply]
