What is Family Portrait and how can take Family picture

The Family Portrait, also known as the Portrait of the Planets, is a photograph of the Solar System taken by Voyager 1 from a distance of approximately 6 billion kilometres from Earth on February 14, 1990. Individual frames of six planets, as well as a partial background showing their relative positions, are featured. The image is made up of 60 individual frames arranged in a mosaic.The last photographs taken by either Voyager spacecraft were used to create the image (which continued to relay other telemetry afterward).

The famous Pale Blue Dot image of the Earth was also created using these frames. Carl Sagan, a member of the Voyager imaging team, advocated for the images to be taken for several years.

Jupiter, Earth, Venus, Saturn, Uranus, and Neptune are visible in the mosaic, from left to right: Jupiter, Earth, Venus, Saturn, Uranus, and Neptune. The picture includes the Sun, which is also a point of light at this wavelength. Three planets (at the time) were overlooked. Mercury was invisible because it was too close to the Sun to be seen. [4] Mars was not observed by the Voyager cameras because of its location, which only produced a thin crescent from the spacecraft's perspective, and Pluto (which was still considered a planet in 1990) was not included because of its small size and distance from the Sun, making it too dim to photograph. Mars should have been imaged using transparent filters instead of the coloured ones used, but by the time this was realised, the process had progressed too far to make the necessary adjustments.

The picture does not seem to be cohesive. Individual frames were taken with a variety of filters and exposures to bring out as much detail as possible. To avoid damaging the Imaging Science System vidicon tubes, the Sun was imaged with the darkest filter and shortest exposure possible. The probe's Wide-Angle Camera captured the bulk of the frames in grayscale, while the Narrow-Angle Camera captured the close-up images of each planet in colour. (5)

The picture was taken at a distance of 40.11 AU (6.0 billion km; 3.7 billion mi) from Earth and at a tilt of 32 degrees above the ecliptic plane. Voyager 1 was chosen to construct the mosaic because its trajectory took it above the plane of the Solar System, and unlike Voyager 2, it was in a position to see Jupiter without being obstructed by the Sun's glare. Using radio telescopes, a reverse image of Voyager 1 was taken in 2013. Although Voyager 1 is not visible to the naked eye, its radio signal is extremely bright when compared to most natural objects studied by radio telescopes.

The Solar System Family Portrait is a photograph of several of the Solar System's planets and moons taken by the MESSENGER spacecraft in November 2010 from a position near Mercury's orbit. The mosaic is meant to accompany the Voyager 1's Family Portrait, which was taken from the Solar System's far reaches on February 14, 1990.

The portrait was made up of 34 individual frames taken with the Mercury Dual Imaging System, focusing on the areas around each planet. The first set of photographs was taken on November 3, 2010, and the second set was taken on November 16, 2010.
