An Illusory Sunrise and Sunset creates an awe inspiring view
An illusory sunrise or sunset, also known as a “false sunrise” or “false sunset,” is a phenomenon that can occur when the sun is still below the horizon but its rays are refracted or bent by the Earth’s atmosphere. This causes the sun’s light to be visible above the horizon, creating the appearance of a sunrise or sunset.

What are Illusory Sunrises and Sunsets?
An illusory sunrise or sunset, also known as a “false sunrise” or “false sunset,” is a phenomenon that can occur when the sun is still below the horizon but its rays are refracted or bent by the Earth’s atmosphere. This causes the sun’s light to be visible above the horizon, creating the appearance of a sunrise or sunset.
The most common type of illusory sunrise or sunset is called a “green flash,” which is a brief burst of green light that can be seen just as the sun appears or disappears below the horizon. This occurs when the atmosphere refracts the sun’s light, separating it into different colors and causing the green light to be visible for a split second.
Illusory sunrises and sunsets are most commonly seen near the ocean, where the horizon is unobstructed, and when the atmosphere is clear and stable. They are rare and can be difficult to observe, but they are considered a beautiful and fascinating natural phenomenon.
How do Illusory Sunrises and Sunsets Work?
Illusory sunrises and sunsets, also known as false sunsets and false sunrises, occur when the sun’s light is refracted or bent by the Earth’s atmosphere. The atmosphere is composed of different layers of air with varying densities and temperatures, and these layers can cause the sun’s rays to bend and scatter in different directions.
When the sun is near the horizon, its light passes through a larger portion of the atmosphere, and this causes more bending of the light. The bending is called refraction, and it causes the light to be spread out into different colors, similar to how light is separated into a rainbow by a prism. This refraction of light can cause the sun to appear to be higher or lower than it actually is, and can even create the appearance of multiple suns or a distorted sun shape.
The most common type of illusory sunrise or sunset is called a green flash. This occurs when the atmosphere separates the sun’s light into different colors, and the green light becomes visible for a brief moment just as the sun disappears below the horizon.
Overall, illusory sunrises and sunsets are a result of the bending and scattering of light by the Earth’s atmosphere, and they are a fascinating and beautiful natural phenomenon.
Some Similar Illusions
There are several other illusions that involve the bending or refraction of light, which are similar to illusory sunrises and sunsets. Here are a few examples:
- Fata Morgana: This is a complex form of mirage, caused by the refraction of light through different layers of the atmosphere. It can create the illusion of castles, ships, or even entire cities floating in the sky.
- Mirage: A mirage is an optical illusion caused by the bending of light as it passes through air layers with different temperatures. It can make objects appear to be displaced or distorted.
- Rainbow: A rainbow is an optical phenomenon that is caused by the refraction, reflection, and dispersion of light in water droplets. It creates a colorful arc in the sky, often seen after a rainstorm.
- Twilight: Twilight is the period of time before sunrise or after sunset when the sky is illuminated by indirect sunlight that is scattered in the upper atmosphere. It can create colorful and dramatic skies, similar to those seen during a sunrise or sunset.
- Halo: A halo is a ring of light that surrounds the sun or moon, caused by the refraction of light through ice crystals in the atmosphere. It can create a striking and ethereal visual effect.
These optical illusions are all caused by the bending or refraction of light, and they can create stunning and sometimes surreal visual experiences.
Discovery of the Illusory Sunrises and Sunsets
The phenomenon of illusory sunrises and sunsets has been observed for centuries, and the underlying science of atmospheric refraction and bending of light has been studied and explained by many scientists over the years.
One of the earliest documented explanations of atmospheric refraction was provided by the ancient Greek philosopher Aristotle, who observed that the apparent position of stars near the horizon was slightly higher than their true position, and he hypothesized that this was due to the bending of light in the Earth’s atmosphere.
In the modern era, several scientists have made significant contributions to our understanding of atmospheric refraction and the formation of illusory sunrises and sunsets. One of the most notable figures is French astronomer Pierre Bouguer, who in the early 18th century conducted experiments and wrote extensively about atmospheric refraction and its effects on celestial observations.
Another important figure in the study of atmospheric optics is English scientist Thomas Young, who in the early 19th century proposed a wave theory of light that helped to explain many optical phenomena, including the bending of light in the atmosphere.
Today, the science of atmospheric optics is a well-established field of study, and scientists continue to investigate and refine our understanding of the complex ways in which light interacts with the Earth’s atmosphere.
