He Sol does not have the color you imaginebut it has a color that perhaps until now you would have never imagined. Knowing a little more about this king star is essential, we must be very aware of a type of element that may end up being the one that makes an important difference. Life on the planet would not be the same, especially if we take into account a type of element that we would never have imagined would be in a very different way.
NASA experts have created a series of elements that have ended up being what makes the difference in every way. A reality that can end up being what marks a before and after, without a doubt, that moment will have arrived to get to know the Sun and really see it as it is. We see it as yellow and we will surely paint it that tone, but in reality, nothing could be further from the truth, perhaps it will end up having a color that has nothing to do with it or perhaps it will end up being the one that accompanies us these days. It will not be what you thought, I hope perhaps it will surprise you in many ways.
The true color of the Sun has been revealed by science
The Sun, the stars and the Moon seem to have the same colorin this case, a yellow tone that will surely surprise us and that may end up being what impacts us from an early age. We live far from these elements, thousands or millions of kilometers away, so we do not see them as they are.
The distance means that we do not see the Sun as it is. It would be impossible to get close to it, but that means we could see it in a very different way. The reality is that we only see one color, in a spectrum that is affected by a type of element that may end up being the one that deceives our eyes.
The senses may end up being very different, but that means that we will have to start thinking about some elements that will accompany us these days. The moment of truth will have arrived. NASA tells us the true color of a Sun on which we depend. This king star perhaps has a very different tone than we imagine. A harsh reality that has been discovered by science that has given us some important data.
As they tell us from the NASA blog: «Our perception of color is influenced, of course, by the wavelength of the emitted light, the intensity of the emitted light (I will explain this later), environmental factors, the ability and limitations of our eyes to gather light and, ultimately, our brains. So let’s start with the wavelength of light. As with all matter, the sun emits a “black body spectrum” that is defined by its surface temperature. A blackbody spectrum is the continuum of radiation at many different wavelengths that is emitted by any body with a temperature above absolute zero. For our sun, this blackbody curve or “Table Function” is a smooth, almost bell-shaped curve involving electromagnetic (EM) radiation at many different wavelengths, from very long infrared to very short ultraviolet wavelengths. During very hot, explosive, high-energy solar flare events, the sun also emits enormous amounts of of seconds! These massive solar flares are huge explosions in the sun’s atmosphere caused by the sudden release of energy from the magnetic field and tend to occur near solar maximum. Flares also accelerate charged particle plasmas to high speeds resulting in radio emission. Therefore, the sun actually emits energy at all wavelengths, from radio to gamma ray. But, as you can see in the image above, it emits most of its energy around 500 nm, which is close to blue-green light. So one could say that the sun is blue-green! This maximum radiation frequency is governed by the temperature of the sun’s surface, around 5,800K. A higher surface temperature would result in a shorter maximum wavelength and our sun could reach its peak point in the blue or violet part of the spectrum (or even in the ultraviolet!). Lower surface temperature, and our sun’s spectrum could peak in the yellow or orange or even red part of the spectrum. But this is physics, not perception. I should point out here another spectral signature of the sun, the flux of photons. If we use the relationship found by Max Planck, E = hf (i.e. Energy = Planck’s Constant times Frequency) and convert solar irradiance into photon counts, the spectral signature across visible wavelengths is much flatter and the sun is perceived as more yellow. If we were above the atmosphere, say on the International Space Station, and looked at the sun (through our filtered visor), the sun would look white! Because? Because although the sun emits strongest in the green part of the spectrum, it also emits strongly in all visible colors, from red to blue (400 nm to 600 nm). Our eyes, which have three color cone cell receptors, inform the brain that each color receptor is fully saturated with significant colors received at all visible wavelengths. “Our brains then integrate these signals into a perceived white color.”
