um... an aurora?
It is either zoomed in or magnified.
A star that pulsates is known as a variable star.
waxing is when it's growing, waning is when it's shrinking
generally speaking things appears the colors that they do because of two things, the way our eyes and brain perceive them and the way the object absorbs and reflects different wavelengths of the light spectrum. our minds interpret the light spectrum as the colors red, orange, yellow, green, blue indigo and violet and any combination of these colors. when light strikes an object, the object absorbs and reflects light waves, for instance if an object appears red to you, it's because the surface of the object absorbs all the other light wavelengths except red, which bounces back to our eye and causes the object to appear red. strangely enough, when all colors of the light spectrum are bounced back to us, we perceive the object to be white and when none of the colors are reflected, we perceive the object to be black!
Mars is sometimes called "the red planet", as it has a reddish tint when observed through a telescope
White light can be split up into lots of different coloured light waves using a prism. We call this range of colours the visible spectrum.

VIBGYOR. * * * * * The previous answer is most unlikely. It would have been called the spectrum. The spectrum is a continuum of colours so there is no obvious reason for seven colours. It is believed that Newton actually noted 4 colours (and intermediate shades) and the 7 colours of the visible spectrum were introduced to align the number with the musical scale. The BIV division seems too artificial. Furthermore, the British acronym is ROYGVIB so VIBGYOR is an unlikely name for Newton to have come up with.
Colours have always existed due to the variation within the visable light spectrum. Who actually named the colour we now call red is anyone's guess. I don't believe there is written record of who named the colours.
you dont make sense
What do you call in a band of colors as seen in a rainbow
We call that the visible or optical spectrum.
The range of colors that white light can be split into is called the visible spectrum. It consists of colors such as red, orange, yellow, green, blue, indigo, and violet.
That's the portion of the spectrum that we call "gamma rays".
The visible portion of the Electromagnetic Spectrum. Visibility to the human eye is determined by the Frequency (or wavelength) of the light.
