About a year ago National Geographic released a television series titled “One Strange Rock.” It can be found on Disney+. This series looks at how life on Earth survives and thrives. It is especially interesting because it tells this story through eight astronauts (and Will Smith!) who have spent about 1,000 days in space. AnContinue reading “One Strange Shield” Continue reading → Continue reading
There are four different processes that shape planetary surfaces; volcanism, tectonics, erosion, and impact catering. Impact catering is the creation of a bowl-shaped impact crater by asteroids or comets striking a planet’s surface. Volcanism is the eruption of molten rock, or lava from an interior onto its surface. Tectonics is the disruption of a planet’sContinue reading “The Geology of Mars” Continue reading → Continue reading
A series of landslides on Ceres’ surface has been photographed last week, displaying solid evidence for frozen water comprising a sizable portion of its composition. Images displayed three different types of landslide classifications. Type I landslides are relatively round and large, similar to rock glaciers and landslides found on Earth. These landslides are found at […]Continue reading → Continue reading
A new study may explain these strange looking ring patterns on Venus’s surface. These geological markers are called coronae and occur when plumes of hot molten rock rise up and disturb the cooler material above it. The rigid surface is then cracked and molten rock can flow through cracks as magma. Scientists did tests in… Continue reading Crown-Like Structures on VenusContinue reading → Continue reading
Enceladus, also known as Saturn II (and my favorite moon in the solar system), is one of the innermost and also the sixth largest moon of Saturn. This moon has an orbital period of 33 hours and reflects almost 100% of the sunlight that strikes, due to it’s icey surface. It was discovered in August […]Continue reading → Continue reading
Mars is the home of the largest volcano in the Solar System: Olympus Mons. It stands 22km above the surface of Mars, and is it so wide it takes up an incredible 300,000 square kilometers of land. In comparison, Mt. Everest is only 8.8km tall, and Olympus Mons is approximately the size of Italy. As seen in […] Continue reading → Continue reading
Although Tennessee is in the middle of North America, we are still affected by tectonic activity. There are earthquakes in this region from time to time, thanks to the New Madrid Fault. This Tectonophysics article helps us understand why there are earthquakes in Tennessee. North America began to rift, or break apart, in the Late […] Continue reading → Continue reading
As many people know, rocks are broken up into three main categories: igneous, metamorphic, and sedimentary. However, the formation processes that govern why one would find a certain type in a certain place is very important to exploration of activity of a terrestrial world. Let’s start with igneous rocks. These are rocks that cool directly […] Continue reading → Continue reading
