The (Possible) Oceans of Europa
Among all of Earth’s unique aspects and characteristics, the presence of water may be the most significant. Water is necessary to life as we know it; from humans ourselves down to microscopic organisms, all living things need water to survive. It is no wonder, then, that life in the Solar System is exclusive to Earth; […] Continue reading
Lack of Cratering: Io and Europa
During class, we have discussed magnetospheres, tectonics, geological activity, and their relation to the cores of the “Big Five”: Earth, Venus, Mercury, the Moon, and Mars. Specifically the moon has very obvious cratering across its entire surface, and its craters remain intact for billions of years. This is due to it not having an atmosphere […] Continue reading

Blog Post 2 – What was Stonehenge really for?
Most people have seen pictures or heard of Stonehenge, an ancient monument on the Salisbury Plain in England. Personally, while I had seen references to Stonehenge in the media, I never actually knew what it was for, or what people thought it was for. It has been difficult for historians to find a definitive answer, […] Continue reading

How Do Moons Form?
Have you ever considered how Earth got its moon in the first place? Astronomers have come up with several theories for why each planet in our solar system has a certain number of moons, and how these moons formed. For Earth’s moon, it is thought a collision with another planet shortly after formation of the […] Continue reading
Moon Phases in the Southern Hemisphere
While reading Chapter 2 in the textbook, I realized how much of a difference living in the southern hemisphere would affect the way you view space. I think we generally tend to think of things as being similar if not the same in the southern hemisphere, especially something as universal as the stars in the […] Continue reading

Blog 8 – Evidence for a Europan Ocean
Europa, Jupiter’s 4th largest and 2nd closest Galilean moon, is thought to have a large saltwater ocean covered by a layer of ice. An article from Nasa details the evidence for the existence of this ocean. The first piece of evidence is the matching zig-zagging cracks on the surface that indicate that the surface was […] Continue reading
The Double Ridges of Europa: An Opportunity For Life
While looking into climate change related developments on the surface of Greenland, associate professor of geophysics at Stanford University’s School of Earth, Energy & Environmental Sciences Dustin Schroeder noticed small double-ridge formations developing, similar to those observed on the surface of Jupiter’s moon, Europa. The double ridges form when pressurized water from below pushes up […] Continue reading
How the Moons Got Their Names
I think one of the most interesting things about the moons of our Solar System is their names. We have named planets after the Greek Roman gods, and most of their moons after characters from myths that relate to those…

The Moons of the Jovian Planets
Some of the most well known moons in our Solar System, aside from our own, are Jupiter’s Moons. They are known as Io, Europa, Ganymede, and Callisto. However, there are over 170 known moons that orbit all of the Jovian…

The Moons of Saturn
There are many moons of Saturn, but the two largest are Titan and Enceladus. Titan is an enormous moon, the second largest in the Solar System after Jupiter’s Ganymede. It is notable for its thick atmosphere, which is made up of mostly Nitrogen compounds. Its surface is characterized as geologically young, with evidence of lakes […] Continue reading
