"What would the ""sky"" look like if there was no atmosphere?" · just now. Report Abuse. it would look black, just like space actually is. The reason the sky is blue is because the sun's light scatters when it enters the atmosphere, and the color blue scatters the best of any of the colors (as the sun's light is white, it contains all colors).

No one could describe the color 'blue' until modern times The sun and reddening dawn's play of color, day and night, cloud and lightning, the air and ether, all these are unfolded before us, again and again ... There was no blue, not in the way that we know the color — it wasn't distinguished from green or darker shades. Geiger looked to see when blue started to appear in languages and found an odd pattern all over the world. Every language first had a word for black and for white, or dark and light.

Blue Moon On July 31st, you should look, because there's going to be a Blue Moon. According to modern folklore, a Blue Moon is the second full moon in a calendar month. Usually months have only one full moon, but occasionally a second one sneaks in. Full moons are separated by 29 days, while most months are 30 or 31 days long; so it is possible to fit two full moons in a single month.

Here's What Those Weird Blue Clouds Mean So if you see blue clouds glowing at night, it may be yet another effect of climate change. The Los Angeles Aqueduct Cascades, which bring water 223 miles from the Owens River in the eastern Sierra Nevada mountains, and 137 miles from the Haiwee Reservoir, are a major source of water for Los Angeles.

Once in a blue moon The 'blue moon' expression with the 'impossibility' meaning is old and dates back to medieval England; for example, a work by William Barlow, the Bishop of Chichester, the Treatyse of the Buryall of the Masse, 1528, included a sarcastic reference to a blue moon: Yf they saye the mone is belewe, We must beleve that it is true.

ASTRONOMY FOR KIDS Blue Giant Blue stars are large and compact, this causes them to burn their fuel quickly which in turn makes their temperature very hot. These stars often run out of fuel in only 10,000 - 100,000 years. A blue giant is extremely bright.

Why does the ocean appear blue? Is it because it reflects the color of the sky? The ocean looks blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue (short wavelength light). So when white light from the sun enters the ocean, it is mostly the blue that gets returned. Same reason the sky is blue..

What Is The Atmosphere? The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. However, much of the shorter wavelength light is absorbed by the gas molecules.

Blue moon: where and when to view the rare cosmic event set to light up the sky The reason why the phenomenon is known as a blue moon is not certain, although according to one explanation the term means betrayer moon (belewe in Old English). On other occasions the moon can actually take on a blue colouring but these are the result of ash spewed into the sky by volcanoes.

Beautiful sunrises and sunsets! Visible light is part of the electromagnetic spectrum that we can see. The blue colors in the sky is due to a process called Rayleigh scattering. Blue and violet colors have shorter wavelengths (0.47 nanometers [nm]), and are typically scattered more due to the gases in our atmosphere.

- Had James Hugh Pruett looked at the actual date of the 1937 Blue Moon, he would have found that it had occurred on August 21, 1937. Also, there were only 12 full moons in 1937. You need 13 full moons in one calendar year to have two full moons in one calendar month.

- In the opposite direction is the Sun, and the Sun moves across the  background of stars also competing a circle every year. In the  summer the Sun is approximately lined up with Orion so that the  stars of Orion can't be seen because of the glare from the Sun.  Actually, Orion is visible in the summer sky, to the east just  before sunrise in the Northern Hemisphere. found this useful. Lourdes Kayed.

"What would the ""sky"" look like if there was no atmosphere?" If there were no atmosphere, the sky would be all black, except for the area directly around the sun, which you would not be able to look anywhere near because it would be so bright, as there would be no atmosphere to block its rays.

- The short wavelengths (blue) of light from the sun are scattered by the atmosphere (which is why the sky appears to be blue.), leaving behind the longer (yellow-red) wavelengths.. From a high-flying airplane, or from the moon, the sun appears to be white.

Is there a hole in the SUN? Enormous black spot detected in our star's atmosphere An enormous black hole has been spotted in the sun - but do not fear, it doesn't spell the end of our solar system. Instead the giant dark spot is a gap in the sun's corona - its scorching hot atmosphere. Holes in the sun's atmosphere are a regular feature and Nasa's Solar Dynamics Observatory (SDO) has detected a particularly large one covering the northern hemisphere of our star.

South American Independence Peru got its independence on July 28th, 1821, and Uruguay on August 25, 1825. Chile declared its independence on 1810, but it came officially the next year, and is celebrated on the 8th of September.olivia earned independence on August 6, 1822, and country was named Bolivia after Simon Bolivar, the South American hero of the independence war.

- This is a good analogy to the study with the Himba tribe by jules Davidoff. They physically saw the blue, but were not able to notice it. Guy Deutsche's daughter Anna saw the blue sky, but wasn't able to put a name to it, almost as if it didn't exist.

Why is the Sky Blue? However, if the Oxygen and Nitrogen atoms were just a LITTLE bigger, the situation might be rather different. The sky might normally be reddish or whitish, with sunsets kind of bluish, and the Sun appearing sort of blue-white.

Why Is the Sea Blue? A: The sea is blue because water, in large quantities, is blue. Also, when the light from the sun hits the water, it gets filtered so that redness is absorbed, allowing more of the blue color to be reflected. Another reason why the sea appears blue is because it reflects the blue color of the sky. Little ocean particles serve as reflective devices, and because the sky surrounds the ocean, the water appears blue. The presence of plant life and algae can cause the sea to appear green, and it may even appear gray when the sky is cloudy.

Why Is the Sea Blue? The Ocean Also Reflects the Sky Color. To some extent, the ocean also reflects the color of the sky. That is why when you look across the ocean, it may look gray if it is cloudy, orange if it is during sunrise or sunset, or brilliant blue if it is a cloudless, sunny day.

On July 21, 2015, NASA released a new Blue Marble photograph taken by a U.S. Deep Space Climate Observatory, a solar weather and Earth observation satellite which was launched in February 2015 and will provide a near-continuous view of the entire sunlit-side of the Earth.

Double Blue Moon in 2018 There are two definitions of a Blue Moon in astronomy; both are a type of Full Moon. If the moon actually looks blue, it's caused by a rare type of dust in the atmosphere.

Rainbow The sun's light is white, but the water droplets break it up into seven different colours, always in this order: RED. ORANGE. YELLOW. GREEN . BLUE. INDIGO. VIOLET. There is an easy way to remember them (a mnemonic): - Richard Of York Gave Battle In Vain. These colours are the visible part of the sun's radiation. But there are many other parts that are not visible to the human eye. For example: - immediately below red is infraRED - immediately beyond violet is ultraVIOLET (UV) You can see more about colours here.

Why is the sky blue? Why are sunsets red? Why is the sky blue? Take a look at light through a prism and notice all the different colors that you can see. Light that looks white to our eyes actually is made up of many different colors. Each color can be thought of as a light wave with a different wavelength (or size).
