Wrapping Up the Solar System – Cameron Klein – Blog #8

Wow. I simply cannot believe that the second semester of my freshman year has come to a close. Entering this class, I was expecting to struggle through just another science course, however, I could not have been more wrong. I have learned more in this class than any other class that I have ever taken. […] Continue reading

bLOG 6: HOW MUCH DOES SIZE MATTER (FOR VOLCANISM and CRYOVOLCANISM)?

Even some of the smallest world in our solar system exhibit (or have exhibited) evidence of volcanism or cryovolcanism. Asteroids like Vesta, with radii of only several hundred kilometers, displays features that indicate that they once exhibited active volcanism and even separation by differentiation. Although their volcanism lasted for periods that were geologically very brief, […] Continue reading

Geology of Mars

Mars has a fascinating geology that is very comparable to Earth in many ways and also shows its very dynamic history. A well known geological feature on Mars is Olympus Mons, the largest volcano in the solar system, which stands at a height of approximately 16 miles and spans 374 miles in diameter. To compare, […] Continue reading

Geology of the Moon and Mercury – Blog 4

After writing my last blog post about atmospheres and the greenhouse effect, when learning that the atmospheres of the Moon and Mercury cause them to be considered practically airless and have no weather, I became heavily intrigued. What makes the Moon and Mercury so different from the other planets in our solar system? Thus, I […] Continue reading

Blog #6: Enceladus’s Tiger Stripes

The Cassini Spacecraft revealed dramatic geysers spewing from Enceladus’s tiger stripes, horizontal, nearly parallel fissures near the moon’s south pole, in 2006. It was believed that these may have been caused by “cryo-volcanism” (icy volcanos!), but new research suggests that it may be caused by the changes in the eccentricity of Enceladus’s orbit over 100 […] Continue reading

Blog #3: Radioactive Decay and Radiometric Dating

Radioactive decay is one of the processes by which Earth produces heat. Radioactive isotopes start off unstable (these are called the parent isotopes), and so they decay into other, more stable daughter/progeny isotopes. The decay produces alpha, beta, or gamma radiation which is then converted into thermal energy. The decay of isotopes like uranium, thorium, […] Continue reading

The Himalayas of Venus

The Himalayas might be considered the most impressive mountain range on Earth, but what about other geological formations on planets around the solar system? Most famously, Olympus Mons is the tallest mountain in the solar system, located on Mars at 21229 meters, and about 2.5 times the size of Mount Everest. Alternatively, while not as […] Continue reading

About Me

Hello! I am a sophomore in the College of Arts and Sciences majoring in Earth and Environmental Science with a minor in Sustainability Studies. I am super excited for this class because I am considering an Astronomy minor and am very interested in the subject in general. My plan after undergrad is to study Planetary Geology in graduate school. Continue reading

Geological Map of the Moon

The United States Geological Survey Astrogeology Science Center and NASA worked together to create a complete geological map of the Moon in early 2020. The map shows the immense amount of impact craters on the moon’s surface. It was made with information from six maps from the Apollo-era in conjunction with modern data. Specifically, dataContinue reading “Geological Map of the Moon” Continue reading

Surface Features of Mercury

Mercury is a terrestrial planet, though it is quite different in appearance than Earth. It’s grey rocky surface more resembles that of the moon, however unlike the moon Mercury has a liquid iron core and is much denser. Moreover, Mercury’s surface features paint an interesting story of past geological occurrences. Mercury formed around 4.6 billionContinue reading “Surface Features of Mercury” Continue reading
