The design of the command sequence to be relayed to the spacecraft and the calculations for each photograph's exposure time were developed by space scientists Candy Hansen of NASA's Jet Propulsion Laboratory and Carolyn Porco of the University of Arizona.[9] The command sequence was then compiled and sent to Voyager 1, with the images taken at 04:48 GMT on February 14, 1990.[16] At that time, the distance between the spacecraft and Earth was 40.47 astronomical units (6,055 million kilometers, 3,762 million miles).[17]

The data from the camera was stored initially in an on-board tape recorder. Transmission to Earth was also delayed by the Magellan and Galileo missions being given priority use of the Deep Space Network. Then, between March and May 1990, Voyager 1 returned 60 frames back to Earth, with the radio signal travelling at the speed of light for nearly five and a half hours to cover the distance.[5]

Three of the frames received showed the Earth as a tiny point of light in empty space. Each frame had 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 became Pale Blue Dot.[18][19]

Of the 640,000 individual pixels that compose each frame, Earth takes up less than one (0.12 of a pixel, according to NASA). The light bands across the photograph are an artifact, the result of sunlight reflecting off parts of the camera and its sunshade, due to the relative proximity between the Sun and the Earth.[5][20] Voyager's point of view was approximately 32° above the ecliptic. Detailed analysis suggested that the camera also detected the Moon, although it is too faint to be visible without special processing.[19]

Pale Blue Dot, which was taken with the narrow-angle camera, was also published as part of a composite picture created from a wide-angle camera photograph showing the Sun and the region of space containing the Earth and Venus. The wide-angle image was inset with two narrow-angle pictures: Pale Blue Dot and a similar photograph of Venus. The wide-angle photograph was taken with the darkest filter (a methane absorption band) and the shortest possible exposure (5 milliseconds), to avoid saturating the camera's vidicon tube with scattered sunlight. Even so, the result was a bright burned-out image with multiple reflections from the optics in the camera and the Sun that appears far larger than the actual dimension of the solar disk. The rays around the Sun are a diffraction pattern of the calibration lamp which is mounted in front of the wide-angle lens.[19]

The "Pale Blue Dot" is a famous photograph of Earth taken by the Voyager 1 space probe from a distance of about 3.7 billion miles (6 billion kilometers) away on February 14, 1990. In the photograph, Earth appears as a tiny point of light, a mere 0.12 pixel in size, against the vastness of space. The term "Pale Blue Dot" was coined by astronomer and author Carl Sagan, who also used it as the title of his 1994 book. Sagan eloquently described the image as a reminder of the fragility and uniqueness of Earth and the need for humanity to cherish and protect it.

When was this Voyager sent to space?  How is earth able to connect to the Voyager?

it was launched...1977 bro...during 2012 it entered the interstellar space...

it was started to study Jupiter and Saturn...after that it was moved to interstellar for further study...

 

the below is , how they communicated... 

The communication between the Voyager spacecraft and Earth is facilitated by the Deep Space Network (DSN). The DSN is a collection of large radio antennas in different parts of the world, managed by NASA, which allows continuous contact with interplanetary spacecraft.

The basic process is as follows:

1. **Command and Data Gathering**: Scientists on Earth compose a command sequence (instructions for what the spacecraft should do) and send it to Voyager. These instructions could be for taking photos, collecting other data, changing course, etc. The data gathered by the spacecraft, including photographs, is stored on an onboard tape recorder.

2. **Data Transmission**: Voyager then sends the data back to Earth via radio signals. These signals are in the form of electromagnetic waves, specifically in the X-band radio wavelength (roughly 8 to 12 gigahertz).

3. **Signal Reception**: The signals are received by the Deep Space Network's large radio antennas. Given the extreme distances involved, the signals are very faint and require these large, sensitive antennas to detect them.

4. **Data Processing**: The received signals are then decoded and processed to form the actual data, such as the images taken by Voyager. This data is then further analyzed and studied by scientists.

For the Voyager missions, this process took a significant amount of time due to the extreme distance between the spacecraft and Earth. For example, in the case of the "Pale Blue Dot" image, the radio signals carrying the image data took over five hours to reach Earth, despite traveling at the speed of light.
