Ambiguity
The first paragraph is ambiguous as to whether the photosphere is the region into which exterior light comes, the region in which exterior light stops, or the region to which no exterior light comes. If anyone could shed some light (no pun intended) on that issue, that would be great. 85.224.198.251 15:49, 25 April 2007 (UTC)

The sun's photosphere is often mistakenly referred to as the surface of the sun.
In reality however, the sun's photosphere is only a "liquid-like" plasma layer made of neon that covers the actual surface of the sun. That visible layer we see with our eyes is more commonly known as penumbral filaments. This visible neon plasma layer, as well as a thicker, deeper plasma layer of silicon, entirely covers the actual rocky, calcium ferrite surface layer of the sun. The visible photosphere covers the transitional region that is the actual surface of the sun, much as the earth's oceans cover most of the surface of the earth. In this case the sun's photosphere is very bright and we cannot see the darker surface features below without the aid of satellite technology.
The composition and mechanical inner workings of the sun beneath the visible photosphere have remained an enigma for thousands of years. There are a whole host of unexplained phenomena related to the sun's activities that still baffle gas model theorists to this day because they fail to recognize the existence of an iron alloy transitional layer that rests beneath the visible photosphere. Fortunately a host of new satellites and the field of heliosiesmology are starting to shed new light on this mysterious transitional layer of the sun that is located about 4800km beneath the visible photosphere. In addition, recent studies of solar wind suggest that solar wind also originates on the same transition layer under the photosphere as do the electrically charged coronal loops. NASA's SOHO satellite and the Trace satellite program have both imaged this transition layer of the sun that sits beneath the photosphere. These 21st century satellites and technologies now enable us to peer behind the outer plasma layers of the chromosphere and photosphere and allow us to study the rocky, calcium ferrite transitional layer with incredible precision.
The reason for the current confusion in gas model circles is simple. The SOHO, TRACE and YOHKOH satellites demonstrate that the sun is not simply a giant ball of gas as Galileo believed based on his limited observations through a common telescope. Just as Dr. Birkeland predicted, the sun has a solid, electrically conductive surface composed of iron ferrites beneath the liquid-like plasma layer of the photosphere. It has a solid and electrically conductive surface that is covered by a series of plasma layers, starting with calcium, silicon, neon, helium and finally a layer of hydrogen that ultimately ignites in the corona. This solid surface model of the sun the Birkeland experimented with in his lab can and does explain the behaviors of our own sun quite elegantly and offers us the best hope of deciphering the stone (in this case iron ferrite) tablet that will help us unlock the mysteries of our universe.
Citations?
The main page for this article appears to list no formal citations from reliable sources (as of this note). Can someone please add some reliable sources to a section for References or citations? I think References is most commonly used? Thx, Mgmirkin (talk) 02:56, 17 January 2008 (UTC)
Incorrect image?
From the article: "The image of the surface shown in the illustration to the right is actually an ultraviolet image of helium plasma at 30.4 nm (from the European Space Agency/NASA SOHO spacecraft), and comes from the chromosphere, which is just above the photosphere, so the "photosphere" label attached to this image is actually incorrect."
If the wrong image is being used, can we please insert a correct image and remove this weird paragraph talking about how someone used the wrong image...? Pretty please? The article will look better without this kind of "oops, we don't know what we're doing, and we're going to tell you we don't know what we're doing" stuff in it. Thx, Mgmirkin (talk) 03:06, 17 January 2008 (UTC)
- Too bad, you didn't reference the image name in your comment. The article history shows that there was once an image called SunLayers.png, but it has mysteriously vanished, along with the caption. A tiny thumbnail of it is still visible if you have Navigation popups enabled in your profile and hover the mouse cursor over one of the earlier links in the history page. A Lithuanian-annotated version of that image appears in the Wikimedia Commons. If the use of the basic image is otherwise legal, it shouldn't be too hard to retouch it and re-annotate it correctly. —QuicksilverT @ 01:12, 11 February 2009 (UTC)
That´s all you can tell ?
What a poor article ! Uncomplete and off the mark. You can do better than that. Or should a third-rate amateur astronomer help you ?? —Preceding unsigned comment added by 145.254.96.121 (talk) 16:41, 27 August 2008 (UTC)

what is the core its not giving me much descriptions... —Preceding unsigned comment added by 75.66.206.120 (talk) 01:34, 9 April 2009 (UTC)
The Sun's photosphere is 74.9% hydrogen and 23.8% helium
"The Sun is composed primarily of the chemical elements hydrogen and helium; they account for 74.9% and 23.8% of the mass of the Sun in the photosphere, respectively. All heavier elements, called metals in astronomy, account for less than 2% of the mass, with oxygen (roughly 1% of the Sun's mass), carbon (0.3%), neon (0.2%), and iron (0.2%) being the most abundant." - Sun 2601:589:4705:C7C0:CD39:BFB6:B7C2:56F0 (talk) 16:21, 23 October 2015 (UTC)
- Hi, what exactly do you want to be changed, if anything? The photospheric composition is already mentioned in the Sun article, too. Gap9551 (talk) 16:26, 23 October 2015 (UTC)
density of about 2×10-4 kg/m3
The article says that's the photosphere's density. But the image on the linked page seems to say it's about 2(?)×10-6 g/ml, which is 10-3 kg/m3. — Preceding unsigned comment added by 208.47.18.162 (talk) 16:09, 29 December 2015 (UTC)
