Ganymede Casts a Huge Shadow Throughout Jupiter in Spectacular New Image From NASA’s Juno Spacecraft


Juno Captures Moon Shadow on Jupiter

Figure 1. Citizen scientist Thomas Thomopoulos created this enhanced-color picture utilizing uncooked knowledge from the JunoCam instrument. At the time the uncooked picture was taken, the Juno spacecraft was about 44,000 miles (71,000 kilometers) above Jupiter’s cloud tops, at a latitude of about 55 levels south, and 15 instances nearer than Ganymede, which orbits about 666,000 miles (1.1 million kilometers) away from Jupiter.

NASA’s Juno spacecraft captured this magnificent view of Jupiter in the course of the mission’s 40th shut cross by the enormous planet on February 25, 2022. The giant, darkish shadow on the left facet of the picture was forged by Jupiter’s moon Ganymede.

Citizen scientist Thomas Thomopoulos created this enhanced-color picture utilizing uncooked knowledge from the JunoCam instrument (Figure 1). At the time the uncooked picture was taken, the Juno spacecraft was about 44,000 miles (71,000 kilometers) above Jupiter’s cloud tops, at a latitude of about 55 levels south, and 15 instances nearer than Ganymede, which orbits about 666,000 miles (1.1 million kilometers) away from Jupiter.

An observer at Jupiter’s cloud tops inside the oval shadow would expertise a complete eclipse of the Sun. Total eclipses are extra widespread on Jupiter than Earth for a number of causes. Jupiter has 4 main moons (Galilean satellites) that always cross between Jupiter and the Sun: in seven days, Ganymede transits as soon as; Europa, twice; and Io, 4 instances. And since Jupiter’s moons orbit in a aircraft near Jupiter’s orbital aircraft, the moon shadows are sometimes forged upon the planet.

JunoCam captured this picture from very near Jupiter, making Ganymede’s shadow seem particularly giant. Figure 2, created by citizen scientist Brian Swift utilizing JunoCam knowledge, illustrates the approximate geometry of the seen space, projected onto a globe of Jupiter.

JunoCam’s uncooked pictures can be found for the general public to peruse and course of into picture merchandise at https://missionjuno.swri.edu/junocam/processing.

Jupiter is the biggest planet within the Solar System and the fifth planet from the Sun. It is a gasoline big with a mass that’s greater than two and a half instances that of all the opposite planets within the Solar System mixed, however is simply about one-thousandth the mass of the Sun. Jupiter, behind the Moon and Venus, is the third brightest pure object within the Earth’s evening sky, and it has been seen since prehistoric instances. It was named after Jupiter, the Roman god and king of the gods.

Ganymede, a satellite tv for pc of the planet Jupiter, is the biggest and most huge of the Solar System’s moons. It is the ninth-biggest object within the Solar System (together with the Sun) and the biggest and not using a important ambiance. It has a diameter of 5,268 kilometers (3,273 miles), making it 26 p.c bigger by quantity than Mercury, however it’s only 45 p.c as huge.
