* Amalthea is the third-closest moon to Jupiter and is about the size of a small town.
* The new photos were taken by the Juno spacecraft, which has been orbiting Jupiter since 2016.
* The photos show Amalthea's surface in unprecedented detail and reveal a variety of features, including craters, ridges, and grooves.
The Juno spacecraft has sent back new photos of Jupiter's tiny moon Amalthea, revealing a surface covered in craters, ridges, and grooves. The photos are the most detailed images ever taken of Amalthea and provide scientists with a new look at this mysterious moon.
Amalthea is the third-closest moon to Jupiter and is about the size of a small town. It orbits Jupiter at a distance of about 181,000 kilometers (112,000 miles) and takes about 12 hours to complete one orbit.
Amalthea is a dark, irregularly-shaped moon with a surface that is covered in craters. The craters range in size from small pits to large basins that are hundreds of kilometers across. The largest crater on Amalthea is called Pan, and it is about 100 kilometers (62 miles) wide.
Amalthea also has a number of ridges and grooves on its surface. The ridges are typically a few kilometers wide and hundreds of kilometers long. The grooves are typically narrower than the ridges and can be up to 100 kilometers (62 miles) long.
The ridges and grooves on Amalthea are thought to be the result of tectonic activity. Tectonic activity is the movement of the moon's crust, which can be caused by a number of factors, such as the gravitational pull of Jupiter or the impact of other moons or asteroids.
The new photos of Amalthea provide scientists with a new look at this mysterious moon. The photos will help scientists to better understand Amalthea's surface and its history.
Here are some additional facts about Amalthea:
* Amalthea is composed primarily of ice and rock.
* Amalthea has a very thin atmosphere that is composed primarily of oxygen and carbon dioxide.
* Amalthea is thought to be a captured moon, meaning that it was not formed in the same place as Jupiter.
* Amalthea is one of the most heavily cratered moons in the Solar System.
