The Galilean Moons

When I went out observing on the 24th Avenue Parking Garage the other night, every astronomical object that I saw through the telescope amazed me, but Jupiter especially captured my attention. I had never viewed Jupiter through a telescope before, and on this beautiful and mostly clear night, I was able to clearly see not […] Continue reading

The deep blue under the crust

NASA’s Cassini mission scientists announced recently that Saturn’s sixth-largest moon, Enceladus, has a warm ocean at its southern pole. The ocean is 9.7 km deep and resides under the moon’s icy crust of about 40 km. Tiny grains of rock were detected by NASA’s Cassini spacecraft near Saturn. This indicates that there may be hydrothermal […] Continue reading

Life on Moons

<Image for this post taken from here> The Galilean moons, especially Europa, have been objects of interest for decades for scientists interested in finding life in our own solar system. Europa’s relatively young surface is, for the most part, devoid of the pockmarked landscapes that signify a geologically inactive world, meaning that there must be … Continue reading Life on Moons Continue reading

Europa’s Ocean

We often think that liquid water is the answer to life in the universe. While it certainly makes some forms of life possible, it doesn’t guarantee their existence. If it did, we would certainly not be alone, even in this solar system, as several Galilean moons are thought to have sub-surface water oceans. The most […] Continue reading

Exploration of Europa

Image Source For years now, scientists have been fascinated with Jupiter’s fourth largest moon known as Europa. What makes Europa such an interesting subject is the fact that it is home to a saltwater ocean beneath a layer of ice. Such characteristics make Europa the most likely other place in our Solar System to have […] Continue reading

The End of an Era

Or, more accurately, the end of a semester.  I’ve had a lot of fun blogging for this class, and I’ve learned a lot about that vast expanse above our heads known as the cosmos.  One of the most important things I’ve learned, I think, is the vastness of space.  Even in our solar system, planets […] Continue reading

The Galilean Moons

The Galilean moons of Jupiter are in order of distance Io, Europa, Ganymede, and Callisto. They are the four largest and most prominent of the 67 moons orbiting Jupiter, these four moons are some of the largest moons in the solar system–Callisto and Ganymede are even larger than Mercury, while Io and Europa are smaller […] Continue reading

Stories about Europa

Among four Galilean moons, my favorite one is Europa. Known as the water world, Europa has huge abundance of liquid water beneath its icy surface. Let’s take a closer look of how this extrapolation of liquid water on Europa. Water is suspected to be the agency that erases Europa’s relatively young surface. The double-ridges on […] Continue reading

Oxygen on Europa?

Europa, which is one of the four largest moons orbiting Jupiter, is currently one of the top candidates for potential life. Europa’s surface is made of ice, but beneath all this ice, is an ocean of water. This water is likely due to tidal heating caused by Jupiter and is evidenced by the magnetic field […] Continue reading
