The Sun has often been perceived by most of us as a glistening golden giant that gives us vital light and heat. The massive star’s real color, though, isn’t yellow, according to astronomers. Furthermore, a NASA astronaut recently endorsed this idea, stating that the Sun is white and just seems yellow to humans.
The confirmation followed the posting of a fact about the Sun and two images of the star by the Twitter user latest in space, who publishes amazing information about astronomy and space. The sun is white, but the atmosphere of Earth gives it a yellow appearance. The Sun was visible in one of the images, where it was dazzling bright white, and in the other, where it was shining yellow light.
The message quickly ignited controversy among space experts, with many disputing the allegation and proposing their hypotheses. Scott Kelly, a former astronaut, was ready to voice his view when the contested assertion gained notice. Kelly replied to the message with, “I can confirm this space fact.
Let’s investigate the cause now that the astronaut has proven that the Sun indeed is white. NASA claims that the yellow color of the Sun is caused by the Earth’s atmosphere, while the human eyes’ ability to distinguish between colors also plays a part. The Sun emits all visible colors of light. However, because of its shorter wavelength, blue light scatters more effectively in the atmosphere, thus humans don’t see the sun’s blue hue.
In addition, all the visible wavelengths in sunlight are attenuated when it reaches humans, so the light does not instantaneously fill the cone receptors in our eyes.
Our Sun still has exactly 5,000 million years left to live, according to the Gaia satellite probe. It is known that the Sun will eventually swallow our planet in a few million years, robbing us of the life that it currently provides.
