NASA's Juno Spacecraft Reveals Reddest Moon Amalthea Transiting Jupiter's Great Red Spot

Amalthea circles Jupiter inside Io's orbit and takes half a day on Earth to complete one orbit.
Amalthea has impact craters, hills, and valleys on its surface. Its red coating remains a mystery.
Amalthea is the reddest object in the solar system with a potato-like shape and a long axis of 155 miles (250 kilometers) and a narrowest point of 79 miles (128 km).
NASA's Juno spacecraft captured rare images of Jupiter's moon Amalthea during its 59th close flyby on March 7, 2024.
Scientists believe electric currents induced in Amalthea's core or tidal stresses from Jupiter's gravity may cause its heat.
The first image of Amalthea was taken when Juno was about 165,000 miles (265,000 kilometers) above Jupiter's cloud tops and at a latitude of about 5 degrees north of the equator.
NASA's Juno Spacecraft Reveals Reddest Moon Amalthea Transiting Jupiter's Great Red Spot

NASA's Juno spacecraft captured rare images of Jupiter's moon Amalthea as it orbited the gas giant planet. The tiny moon, discovered in 1892 by Edward Emerson Barnard, is the reddest object in the solar system and has a potato-like shape with a long axis of 155 miles (250 kilometers) and a narrowest point of 79 miles (128 km).

During Juno's 59th close flyby on March 7, the spacecraft took images of Amalthea transiting Jupiter's Great Red Spot. The moon circles Jupiter inside Io's orbit and takes half a day on Earth to complete one orbit. Scientists believe that electric currents induced in Amalthea's core or tidal stresses from Jupiter's gravity may cause its heat.

The first image of Amalthea was taken when Juno was about 165,000 miles (265,000 kilometers) above Jupiter's cloud tops and at a latitude of about 5 degrees north of the equator. Citizen scientist Gerald Eichstädt processed the raw data from JunoCam to enhance the clarity of the images.

Amalthea is an intriguing natural satellite, with impact craters, hills, and valleys on its surface. Its red coating remains a mystery and adds to Jupiter's allure as a fascinating celestial body.

    The author makes several statements about Amalthea being the reddest object in the solar system and its unusual heat emission. However, these statements are based on NASA's assessment of the moon and not directly observed or proven by the author. Therefore, there is an appeal to authority fallacy. Additionally, there is a dichotomous depiction of Amalthea being both very red and giving out more heat than it receives from the sun without providing any evidence or explanation for this phenomenon.
