in january of 1996 Voyager 2 took pictures of rings around uranus (oh, come on grow up) (jk jk don’t)
This image was returned by the Voyager 2 spacecraft on July 3, 1989, when it was 76 million kilometers (47 million miles) from Neptune. The planet and its largest satellite, Triton, are captured in the field of view of Voyager’s narrow-angle camera. (via)
Portrait de famille
Le 14 février 1990, voici 20 ans, Voyager 1 évoluait à un peu plus de 6 milliards de km de la Terre après avoir survolé Jupiter en 1979 et Saturne en 1980. La sonde de la NASA accomplit alors un véritable portrait de famille du système solaire avec une soixantaine de clichés. Notre planète n’est alors qu’un petit point faiblard (et bleuté dans la version couleur), histoire de nous faire prendre conscience de notre «importance» toute relative dans l’Univers comme le souligna avec talent l’astronome Carl Sagan (1934-1996)

Un point bleu pâle : réflexion de l’astronome Carl Sagan
20 years ago today on 14 February 1990, Voyager 1 was flying a little more than 6 billion km from the Earth, after having flown past Jupiter in 1979 and Saturn in 1980. NASA’s probe managed to take sixty or so photographs, making a complete family portrait of the solar system. Our planet is but a small dim dot (with a bluish tinge in the colour version), making us aware of our relative “importance” in the Universe as the talented astronomer Carl Sagan (1934-1996) underlined.

A pale blue dot: reflections of astronomer Carl Sagan
The “pale blue dot” picture is 20 years-old.
Taken in 1990 by NASA’s Voyager 1 spacecraft, the “pale blue dot” photo shows what our planet looks like from four billion miles away. Earth is the tiny speck of light indicated by the arrow, and enlarged in the upper left-hand corner. The pale streak over Earth is an artifact of sunlight scattering in the camera’s optics.
“Electroplated onto the record’s cover is an ultra-pure source of uranium-238 with a radioactivity of about 0.00026 microcuries. The steady decay of the uranium source into its daughter isotopes makes it a kind of radioactive clock. Half of the uranium-238 will decay in 4.51 billion years. Thus, by examining this two-centimeter diameter area on the record plate and measuring the amount of daughter elements to the remaining uranium-238, an extraterrestrial recipient of the Voyager spacecraft could calculate the time elapsed since a spot of uranium was placed aboard the spacecraft. This should be a check on the epoch of launch, which is also described by the pulsar map on the record cover.”
What a hopeful, peculiar note-in-a-bottle.
First Picture of the Earth and Moon in a Single Frame
This picture of the Earth and Moon in a single frame, the first of its kind ever taken by a spacecraft, was recorded September 18, 1977
