Its Near-Infrared Camera captured auroras, moons and the Great Red Spot

Europa became an interest to researchers as a place that potentially could harbor life after observations from Earth-bound telescopes and space probes found evidence of an ocean 10 to 15 miles beneath the icy surface. This drawing illustrates a possible water pocket within the ice that may contribute to ridges forming on the moon's surface.

Europa's Icy Shell May Be Habitable for Life

The moon of Jupiter could have shallow water pockets within its frozen surface

The moons appear as two blurry dots located close together in the upper right area of the image. Io, seen as a darker speck on the left of the two dots, is the most volcanically active world in the solar system. Europa is seen on the right and features a global ocean beneath its icy surface.

NASA’s Hubble Space Telescope snapped this picture of the Centaur LD2 as it orbited near Jupiter.

The Ambitious Idea to Study the Evolution of a Comet

Researchers want to send a spacecraft near Jupiter to join up with a chunk of rock and ice as it’s flung toward the sun

Lucy measures more than 46 feet wide, and about 24 feet tall and is equipped with solar arrays on its main body that allow it to power up its instruments. Each camera will enable Lucy to study the surface of the asteroids, detect traces of water or minerals, and count craters or rings.

Jupiter and its largest moon Ganymede are shown in this image. Ganymede is slightly larger than the planet Mercury. Meanwhile, Jupiter's new 80th moon is much smaller, likely only a few dozen miles in diameter.

Amateur Astronomer Discovers New Moon Orbiting Jupiter

Kai Ly spotted the unnamed satellite using telescope images from 2003

Streaked across Ganymede's surface are bright light-colored regions of ridges and grooves that overlap darker-colored terrains along the icy shell. The textured scar-like areas suggest that the moon's surface underwent extreme geologic changes over time.

NASA's Juno Space Probe Zooms by Largest Moon in the Solar System

The flyby will be the closest any spacecraft has flown near Ganymede in over two decades

In the images, the Great Red Spot, Jupiter's superstorm, is seen in both visible and ultraviolet light, but it disappears into the background as a black splotch in the infrared image.
