Common things that we can see in the sky are clouds, raindrops, the Sun, the Moon, stars, airplanes, kites, and birds.

The sun, moon, stars, clouds, birds, and airplanes all have properties, locations, and movements that can be observed and described. As children become more familiar with objects in the sky, they can be guided to observe changes, such as night and day and the seasons.

The astronomical horizon and true horizon are celestial horizons. The local horizon, also called the geometrical horizon, is the visible boundary between the Earth and sky. The local horizon may include trees, buildings, and mountains. The geographic horizon is the apparent boundary between the Earth and sky.

Blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

The blue color of the sky is a result of this scattering process. At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered.

When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically good weather will follow.

It is red. Since it is morning you are looking east, and the red sky indicates that there is high pressure there. Because you are in the mid-latitudes, the high is moving eastward–away from you. That could only mean that a low, and very likely an associated storm, is moving toward you from the west.

“Red sky at night, shepherds delight” can often be proven true, since red sky at night means fair weather is generally headed towards you. A red sky at sunset means high pressure is moving in from the west, so therefore the next day will usually be dry and pleasant.

The Answer: Red sky at night, The origin of the red sky proverb can be traced back to the Bible where in the book of Matthew, Jesus says to a group of fishermen, “When it is evening, you say, ‘It will be fair weather, for the sky is red’ and in the morning, ‘It will be stormy today, for the sky is red and threatening.”

A red sky in the morning means that the sky is clear to the east, where the sun is rising, but cloudy overhead, suggesting that the clouds are only just beginning to move in. So, in this part of the world, a red sky in the morning usually means bad weather is to come.

If the morning skies are of an orange-red glow, it signifies a high-pressure air mass with stable air-trapping particles, like dust, which scatters the sun’s blue light. This high pressure is moving towards the east, and a low-pressure system moves in from the west.

“The orange hue is caused by the same process that causes the vivid colors at sunsets. Shorter wavelengths of light (blue) are scattered quickly, leaving only the yellow-orange-red end of the spectrum,” the weather service reports.

The red color was caused by smoke in the air due to wildfires in the West this week. Bottom line: Wildfires cause red skies because sky color is a matter of particle size, and because wildfires introduce differently sized particles into our air.

Pink Sky At Night, Sailors Delight; Pink Sky In Morning, Sailors Warning. This means that if there is pink sky at night there will be good weather tomorrow. But, if there is pink sky in the morning there will be bad weather the same day. This quote originally came from biblical content.

However, at sunset, light has further to travel through the atmosphere. The shorter wavelength blue light is scattered further, as the sunlight passes over a greater distance, and we see the longer wavelength yellow and red light. These effects are a cause of Rayleigh Scattering.

When particles, such as smoke or dust, fill the atmosphere, the longer wavelengths of light — which look red — scatter more effectively. If the air is cleaner, there are more air molecules, which scatter shorter wavelengths or light, or blue light, more effectively. (Think clear blue sky.)

The unusual colour of the sky and the redness of the sun today is likely to be due to smoke from wildfires occurring over northern Iberia along with desert dust high up in the atmosphere originating from North Africa.

Around sunrise and sunset, the added smoke particles can produce vivid colors. The sun has to travel further to reach our eyes, so the blue and violet light is scattered even more when there are added particles in the atmosphere. Red and oranges then reach our eyes and make for a beautiful sight.

It is a common misconception that the Sun is yellow, or orange or even red. However, the Sun is essentially all colors mixed together, which appear to our eyes as white. This is easy to see in pictures taken from space.

When sunlight travels through the sky, it passes through evaporated water and gas and clouds and other particles in the air. These particles both refract and reflect the light, scattering some of sunlight’s colors. In turn, the morning sunlight fills the sky with a blaze of pinks and reds.

Red, orange and pink clouds occur almost entirely at sunrise and sunset and are the result of the scattering of sunlight by the atmosphere. The clouds do not become that color; they are reflecting long and unscattered rays of sunlight, which are predominant at those hours.

The light passes through a thin layer of atmosphere. When they are low in the sky they pass through much more air and that filters the colors to allow the dominant colors of red, orange, and yellow to be more prominent.” Basically, it’s the sun reflecting off the clouds and rain droplets as the storm moved north.

Alpenglow (from German: Alpenglühen, lit. ‘Alps glow’, Italian: enrosadira) is an optical phenomenon that appears as a horizontal reddish glow near the horizon opposite to the Sun when the solar disk is just below the horizon.

Volcanic ash rarely reaches this height but when it does it, it creates an unusual sunset color. The purple-ish hue is produced when fine volcanic aerosols reach the stratosphere and scatter blue light, which when mixed with ordinary sunset red, produces a violet tone.

Sunset is distinct from twilight, which is divided into three stages, the first being civil twilight, which begins once the Sun has disappeared below the horizon, and continues until it descends to 6 degrees below the horizon; the second phase is nautical twilight, between 6 and 12 degrees below the horizon; and the …

The colors of the sunset result from a phenomenon called scattering. Molecules and small particles in the atmosphere change the direction of light rays, causing them to scatter. The short-wavelength blue and violet are scattered by molecules in the air much more than other colors of the spectrum.
