NASA’s Hubble Space Telescope captured images of Jupiter’s auroras on the poles of the gas giant. The observations were supported by measurements taken by NASA’s Juno spacecraft. Juno will begin orbiting Jupiter on July 4.
This artist rendering shows Juno orbiting Jupiter. The Juno spacecraft will study Jupiter from a polar orbit, coming about 3,000 miles (5,000 kilometers) from the cloud tops of the gas giant.
Jupiter and the gaseous planet’s four largest moons — Io, Europa, Ganymede and Callisto — in a photo take by Juno on June 21, 2016, when the spacecraft was 6.8 million miles (10.9 million kilometers) from the planet.
Juno made a flyby of Earth in October 2014. This trio of images were taken by the spacecraft’s Junocam.
Three LEGO figurines are flying aboard the Juno spacecraft. They represent the Roman god Jupiter, his wife Juno and Galileo Galilei — the scientist who discovered Jupiter’s four largest moons on January 7, 1610.
Jupiter was 445 million miles (716 million kilometers) from Earth when Juno was launched from Cape Canaveral on August 5, 2011. But the probe traveled a total distance of 1,740 million miles (2,800 million kilometers) to reach Jupiter, making a flyby of Earth to help pick up speed.
Technicians use a crane to lower Juno onto a stand where the spacecraft was loaded with fuel for its mission.
Technicians test the three massive solar arrays that power the Juno spacecraft. In this photo taken on February 2, 2011, each solar array is unfurled at a Lockheed Martin Space Systems facility in Denver, Colorado.
