Juno's first in-orbit picture of Jupiter and Galilean Moons is awesome


NASA's Juno spacecraft, now in orbit of Jupiter, has taken its first in-orbit image of the Jovian system. This incredible image was taken by the instrument JunoCam from ~2.7 million miles away from Jupiter.

Here's the information about the image from NASA (taken from the page where you can download the full-size image):
"This color view from NASA's Juno spacecraft is made from some of the first images taken by JunoCam after the spacecraft entered orbit around Jupiter on July 5th (UTC). The view shows that JunoCam survived its first pass through Jupiter's extreme radiation environment, and is ready to collect images of the giant planet as Juno begins its mission.
The image was taken on July 10, 2016 at 5:30 UTC, when the spacecraft was 2.7 million miles (4.3 million kilometers) from Jupiter on the outbound leg of its initial 53.5-day capture orbit. The image shows atmospheric features on Jupiter, including the Great Red Spot, and three of Jupiter's four largest moons.
JunoCam will continue to image Jupiter during Juno's capture orbits. The first high-resolution images of the planet will be taken on August 27 when the Juno spacecraft makes its next close pass to Jupiter.
NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. The Juno mission is part of the New Frontiers Program managed at NASA's Marshall Space Flight Center in Huntsville, Ala. Lockheed Martin Space Systems, Denver, built the spacecraft. JPL is a division of the California Institute of Technology in Pasadena."
This picture shows the relative size and structure of Juno and offers information about the instruments. You can find more info on the NASA page for Juno.

"Voyagers" by Santiago Menghini

Voyager 1, traversing the heavens (NASA/JPL)

The Voyager spacecraft were launched in 1977, at a time when the alignments of the outer planets would allow for a "Grand Tour" of the Solar System. 

Voyager 1 traveled past Jupiter and Saturn, discovering volcanoes on Io and the thick atmosphere of Titan, before it was turned around to take pictures of the planets as it traveled beyond their orbits. The famous Pale Blue Dot picture was taken by Voyager 1 when it was over 40 times further from the Sun than Earth. Since that time, Voyager 1 has passed beyond the region of space where the solar wind from our star dominates over other stars; Voyager 1 is now an interstellar traveler.

Voyager 2, while not garnering as much fame as its twin, is the only spacecraft to ever flyby Uranus and Neptune. All of our best detailed information regarding those worlds and their moons comes from Voyager 2, which passed by Uranus in 1986 and Neptune in 1989. For instance, the odd surface of Neptune's moon Triton was revealed by Voyager 2, giving us the first hints that cryovolcanism is a process which occurs on the icy worlds of our solar system.

Recently, filmmaker Santiago Menghini has put together a short film highlighting the journeys of the Voyager spacecraft. Including photographs from the missions as well as sounds from the plasma frequencies of the planets, the film is a tribute to the successes of the Voyager mission. I highly recommend checking out the movie (below, or at Vimeo). Turn up your speakers' volume and full screen this one, you won't regret it.
