The upper rim of the Sun is green while the lower rim is red in this image taken as the Sun sets behind the Golden Gate Bridge. As an astronomical object sets or rises, the light it emits travels through the atmosphere , which works as a prism separating the light into different colors.
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height.

The reddish color of the Sun when it is observed through a thick atmosphere, as during a sunrise or sunset. This is because long-wavelength (red) light is scattered less than blue light. The red light reaches the observer's eye, whereas the blue light is scattered out of the line of sight.
Because of the increased sensitivity of the human eye to blue and green wavelengths when viewing low-luminances (the Purkinje effect) in the night sky, different sources produce dramatically different amounts of visible skyglow from the same amount of light sent into the atmosphere. To reduce light pollution caused by blue light, it is ...
Mushrooms, molds, and other fungi are not plants, despite similarities in their morphology and lifestyle. The historical classification of fungi as plants is defunct, and although they are still commonly included in botany curricula and textbooks, modern molecular evidence shows that fungi are more closely related to animals than to plants.
Height: It is a very large plant and can be 20 feet tall. Dangers: The sap of the plant is highly toxic and can cause sensitivity to UV rays. This can lead to severe blistering and burning from ...
Leaves, stems, and green unripe fruit of the tomato plant also contain small amounts of the poisonous alkaloid tomatine, [36] although levels are generally too small to be dangerous. [36] [37] Ripe tomatoes do not contain any detectable tomatine. [36] Tomato plants can be toxic to dogs if they eat large amounts of the fruit or chew the plant ...
If finalized, the rule can help protect consumers from harmful exposure to asbestos, leading to fewer illnesses such as lung and ovarian cancers, the health regulator said. CONTEXT.
