Mercury is Tectonically Active Planet, Planetary Scientists Say

This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER’s primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up the planet’s surface.

Recent images from NASA’s MESSENGER spacecraft reveal small fault scarps on Mercury’s surface. These cliff-like landforms are small enough that planetary scientists believe they must be geologically young, which means the planet is still contracting and that Earth is not the only tectonically active planet in the Solar System, as previously thought. This colorful view of Mercury was produced by using images from the color base map imaging campaign...

In 2012 Cassini spotted a cloud system called the south polar vortex in Titan’s atmosphere at an altitude of about 186 miles. The spacecraft’s instrument has now detected a massive ice cloud below it. This image was taken by Cassini in 2013. Image credit: NASA / JPL-Caltech / Space Science Institute.

Valleys younger than better-known ancient valley networks on Mars are evident on the landscape in the northern Arabia Terra region, particularly in the area mapped here with color-coded topographical information overlaid onto a photo mosaic. The area includes a basin informally named ‘Heart Lake’ at upper left. Data from NASA’s Mars Global Surveyor orbiter are coded here as white and purple for lower elevations, yellow for higher elevation. The elevation information is combined with a mosaic of images from NASA’s Mars Odyssey orbiter, covering an area about 120 miles (about 190 km) wide. The mapped area is centered near 35.91 degrees north latitude, 1 degree east longitude on Mars. Image credit: NASA / JPL-Caltech / ASU.
