Newton originally divided the spectrum into six named colors: red, orange, yellow, green, blue, and violet.

The Sun is a natural source for visible light waves and our eyes see the reflection of this sunlight off the objects around us. The color of an object that we see is the color of light reflected. All other colors are absorbed.

Through his experiments with prisms, he was the first to demonstrate that white light is composed of the colors of the spectrum. Seven colors constitute white light: red, orange, yellow, green, blue, indigo, and violet.

White light is called as white because it consists of seven colors. The sunlight splits into seven colors namely violet, indigo, blue, green, orange, and red. We usually call it as VIBGYOR. When we mix all these colors we just get one light which is the WHITE light.

White light is made up of the following colours: red, orange, yellow, green, blue, indigo, and violet. Each coloured light has its own wavelength.

White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow. Combining primary colors of light like red, blue, and green creates secondary colors: yellow, cyan, and magenta. All other colors can be broken down into different combinations of the three primary colors.

The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.

The term originates because for a blackbody all visible light will be absorbed rather than reflected, and therefore the surface will appear black. A star, like the Sun is a near perfect blackbody. A blackbody does not reflect any light, nor does it allow any light to pass through (transmit).

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.

Our sun is one object in the sky that everyone can see, but no one can look at. Far and away the brightest object in the sky, the sun is easy to find, but it’s so bright that one can’t look directly at it without vision damage. SOHO stands for Solar and Heliospheric Observatory.

According to their system of classification, the Sun is known as a yellow dwarf star. So the Sun is at the higher end of this group. The official designation is as a G V star. Stars in the this classification have a surface temperature between 5,300 and 6,000 K, and fuse hydrogen into helium to generate their light.

PSR B12620-26 b The exoplanet known as PSR B12620-26 b is the oldest known planet in the universe, with an estimated age of about 13 billion years.

The Sun is ~4.603 billion yrs old and Earth is 4.54 billion yrs old. So in . 063 billion years or 63 million years the planets were all formed in the order stated the oldest(first created) being outer and the youngest being inner planets.

GN-z11 is the youngest and most distant galaxy scientists have observed. This video zooms to its location, some 32 billion light-years away. GN-z11 is 13.4 billion years old and formed 400 million years after the Big Bang. Its irregular shape is typical for galaxies of that time period.

Surviving a Powerful Event. In a report by Futurism, a team of astronomers observed what they believe is the youngest neutron star 170,000 light-years away from Earth in a satellite galaxy of our very own Milky Way, which is known as SN 1987A.

The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun. Like Baskin-Robbins, Wolf-Rayet stars come in a variety of flavors.

The temperatures on this brown dwarf – a star without the mass to burn nuclear fuel and radiate light – is between minus-54 and 9 degrees Fahrenheit. Brown dwarfs lack the mass to shed light or much heat, making them hard to detect without a telescope that can use an infrared lens.

Throughout most of a star’s life, it is burning hydrogen at its core, which creates lots of energy and thus makes it appear blue. As stars age, they run out of hydrogen to burn, decreasing the amount of energy they emit.
