NASA's Voyager 1 and 2 space probes, which were launched within days of each other in 1977, captured some stunning images of planets in our solar system before starting their journey towards interstellar space.
According to NASA, the photography of Jupiter started in January 1979. Voyager 1 completed its Jupiter encounter in early April, after taking almost 19,000 pictures. Voyager 2 picked up the baton in late April and its encounter continued into August. Both probes clicked over 33,000 images of the solar system's biggest planet.
The Voyager 1 and 2 Saturn encounters occurred nine months apart, in November 1980 and August 1981. Here again, the probes clicked multiple images of the planet.
On Jan 24, 1986, Voyager 2 came within 81,800 kilometres of Uranus' cloud tops. The probe clicked thousands of images and gathered extensive data on the planet's moons, rings, atmosphere and magnetic environment.
In 1989, Voyager 2 became the first spacecraft to observe Neptune, passing nearly 5,000 km above its north pole.
''Pale Blue Dot" is perhaps one of the most iconic space photographs ever taken. Voyager 1 was speeding out of the solar system when mission managers commanded it to look back towards home a final time. And this is when the image of the Pale Blue Dot was captured.
