Triple Transit and Mutual Events
20.08.2021

These three panels feature the Solar System's ruling gas giant Jupiter on August 15 as seen from Cebu City, Phillipines, planet Earth. On that date the well-timed telescopic views detail some remarkable performances, transits and mutual events, by Jupiter's Galilean moons.

Moons and Jupiter
12.04.2017

On April 10, a Full Moon and Jupiter shared this telephoto field of view. Both were near opposition, opposite the Sun in Earth's night sky. Captured when a passing cloud bank dimmmed...

Juno Approaching Jupiter
30.06.2016

Approaching over the north pole after nearly a five-year journey, Juno enjoys a perspective on Jupiter not often seen, even by spacecraft from Earth that usually swing by closer to Jupiter's equator. Looking...

Jupiter Rotates as Moons Orbit
24.10.2022

Jupiter and its moons move like our Sun and its planets. Similarly, Jupiter spins while its moons circle around. JupiterБs rotation can be observed by tracking circulating dark belts and light zones. The Great Red Spot, the largest storm known, rotates to become visible after about 15 seconds in the 48-second time lapse video.

Moons at Twilight
3.02.2022

Even though Jupiter was the only planet visible in the evening sky on February 2, it shared the twilight above the western horizon with the Solar System's brightest moons. In a single exposure...

APOD: 2020 September 2 Б Jupiter and the Moons
1.09.2020

How many moons do you see? Many people would say one, referring to the Earth's Moon, prominent on the lower left. But take a closer look at the object on the upper right.

Io Rotating
24.10.2000

The surface of Io is continually changing. Jupiter's moon is the home to many powerful volcanoes so active they are effectively turning the moon inside out. The above time-lapse sequence is a composite of images taken during two space missions that approached the violent moon: Voyager and Galileo.

Io Volcano: Pele's Hot Lava
25.11.1999

Glowing hot lava from the heart of Io's volcano Pele is visible in this false-color infrared composite image. It was recorded last month during the Galileo spacecraft's close flyby of the Jovian moon.

Io Aurora
16.10.1998

Alluring aurora surrounding Io (eye-oh) appear as a ghostly glow while the volcanic moon orbits within Jupiter's dark shadow. Gas giant Jupiter is off to the right of this image, recorded in May by the robot Galileo spacecraft's solid state imaging camera from a distance of about 1.3 million kilometers.

Europa Rotating
15.01.2001

Evidence has been mounting that beneath the vast planes of ice that cover Europa lies water -- liquid oceans that might be home to alien life. The smallest of Jupiter's Galilean Moons (which include Io, Ganymede, and Callisto), Europa's deep interior is composed of mostly of silicate rock.
