Sun shed solar glass

Relatively recent measurements indicate that the Sun is nearly the roundest object ever measured. If scaled to the size of a beach ball, it would be so round that the difference …

Approximating the sun as a black body effectively means that it''s surface temperature is 5800K. And, indeed, if we look at the most dominant wavelength of the sun …

The sun''s spectrum is very complex, and indeed there are a lot of "lines"—both light and dark (emission and absorption)—amidst a sea of what looks to be continuous frequencies. …

If this is the case, then when we read things like what time sun sets and rises on websites, books, calendars, other official times, et al… does that mean when we see for …

Assume you''re talking to someone ignorant of the basic facts of astronomy. How would you prove to them that Earth orbits the Sun? Similarly, how would you prove to them …

I want to know how much lux the sun emits on a bright day - I don''t mean when one stares directly at the sun, but rather when one walks casually outside when the sun is …

The Sun is about as white as white can get. When Venus or the Moon rises, they start as dim yellowish or reddish objects, getting whiter and brighter as they rise above the …

It''s consensus that the very similar apparent sizes of the Moon and the Sun as seen from Earth is a coincidence (as already answered in this site). This provides us with …

The Sun appears white at noon because the sunlight reaching the observer maintains its full spectral composition, meaning that all visible wavelengths arrive in nearly …

The Sun is generating energy by nuclear fusion. This nuclear fusion will emit energy in the form of gamma rays. Normally, the earth''s ozone layer filters the ultraviolet radiation …
