<p class="p__0">The telecommunication capability also decreased with range, restricting the number of information modes that could be utilized by the imaging system. After taking the series of images, which included Pale Blue Dot, NASA mission supervisors commanded Voyager 1 to power its electronic cameras down, as the spacecraft was not going to fly near anything else of significance for the rest of its objective, while other instruments that were still gathering information needed power for the long journey to interstellar space.</p>

<p class="p__1">The command sequence was then assembled and sent out to Voyager 1, with the images taken at 04:48 GMT on February 14, 1990. Read This from the video camera was kept at first in an on-board tape recorder. Transmission to Earth was also delayed by the and objectives being given top priority use of the Deep Space Network.</p>

<p class="p__2">Three of the frames got revealed the Earth as a small point of light in void. Each frame had actually been taken using a different color filter: blue, green and violet, with exposure times of 0. 72, 0. 48 and 0. 72 seconds respectively. The three frames were then recombined to produce the image that ended up being Pale Blue Dot.</p>

<p class="p__3">12 of a pixel, according to NASA). The light bands across the photo are an artifact, the result of sunshine reflecting off parts of the electronic camera and its sunshade, due to the relative distance in between the Sun and the Earth. Voyager's point of view was roughly 32 above the ecliptic.</p>

<p class="p__4">The wide-angle image was inset with 2 narrow-angle photos: Pale Blue Dot and a comparable picture of Venus. The wide-angle photograph was taken with the darkest filter (a methane absorption band) and the quickest possible direct exposure (5 milliseconds), to prevent saturating the cam's vidicon tube with scattered sunshine. However, the result was a brilliant burned-out image with several reflections from the optics in the cam and the Sun that appears far bigger than the actual dimension of the solar disk.</p>

<p class="p__5">Pale blue color [modify] Earth looks like a blue dot in the photograph primarily since of Rayleigh scattering of sunshine in its environment. In Earth's air, short-wavelength visible light such as blue light is spread to a greater extent than longer wavelength light such as red light, which is the reason the sky appears blue from Earth.</p>
