The stars fascinate us with their bright and pure white colors. But how logical is it that they all have the same color?

Bride, Are the stars really white or do they just appear that way to us? let’s see.

The objects around us have all the colors of the rainbow, from red to purple.

When we see or photograph an object through a large telescope, we collect enough light to see these colors. If we don’t have a telescope or a camera, we see objects as shades of white.

The reason for this color change has to do with our eyes, not with objects. Colors change to shades of white because our eyes contain two different visual systemsThe first of these is the color-sensitive system consisting of cone-shaped cells, and the second is the monochrome system consisting of rod-shaped cells.

Cones; It contains the three pigments most sensitive to light: green, blue and red.

In addition, cones are concentrated in a central area called the fovea and have very sharp focusing ability. Rod-shaped cells It contains a single pigment called rhodopsin and surrounds the fovea.

They cannot focus an image as sharply as cones. However, rod cells have a significant advantage over cone cells. For their work they require only a quarter of the intensity of colored light.

Our eyes are of course sensitive to green and blue light, but our brain gives all light sensations a white tint in rod-shaped cells.

Rhodopsin, known as a purple pigment that helps us see in low light, is Unlike color-sensitive pigments, it turns white in intense light. During the day, the low beam system is effectively switched off.

As darkness increases, rhodopsin becomes more sensitive again because color pigments no longer respond to dim light. In summary, if the color of the object is bright enough, this is the color you see in the photo. Otherwise, it looks like a white tint.

So even though the stars you see are not white in color, For all these reasons, your eyes tend to see them as white.
