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
Blog 5: Comets
Comets are relatively small bodies in our solar system comprised of dust, rock, gases, and ice. They are remnants from the formation of the solar system, and their solid bodies, or nuclei, can range from a few miles to dozens of miles wide. When its orbit gets close to the sun, this nucleus heats up […] Continue reading

The Moons of Jupiter
Jupiter has many moons, but the largest of them are the Galilean moon, Ganymede, Callisto, Europa, and Io. This post will explore the defining features of these Jovian moons. The largest of Jupiter’s moons is Ganymede, the largest moon in the Solar System. In fact, Ganymede is larger than Mercury. This moon has a liquid […] Continue reading
Jupiter’s Great Red Spot
Growing up, I grew to recognize Jupiter’s distinctive birthmark, but I never attempted to understand it. I figured their were clever astronomers out there who knew what was going on and I’d end up absorbing what they know from a TED talk at 1.5x speed. After looking into it though, it turns out the Great […] Continue reading

Hot Jupiters: Migration and Orbital Changes
Hot Jupiters are gas giants that have orbital periods that are very close to their stars; often less than 10 days. Usually this means they are less than 0.1AU away from their stars which is one tenth the distance between earth and the sun. While scientists originally did not think giant planets could exist this […] Continue reading

Enceladus: Alien Life in Our Own Solar System?
Enceladus is an icy moon of Saturn, and is fairly small (or medium-sized, for a moon) with a diameter of about 500 km. For reference, the Moon has a diameter of about 3,475 km. Despite its size, however, Enceladus has been rated as among the most probable sources of life in our own solar system […] Continue reading
Blog Post 5: Comets and their Tails
Comets are large balls of dust, rock, and ice that travel across our solar system and other solar systems. They are large like asteroids, around 10 km in diameter in our solar system. The largest one in our Solar System is Bernardinelli-Bernstein, a massive body about 85 miles in diameter. These objects can approach near […] Continue reading

Possibility of Life on Europa
Picture from European Space Agency As of now scientists believe there are three requirements for a planet to develop and sustain life. Liquid water, the appropriate chemical elements, and an energy source. Europa has more than enough water, as it is believed that below the roughly 15 miles of solid ice, lies twice as much …

Pluto: dwarfPLANET
Growing up with Pluto being known as the ninth planet, I’m interested in Pluto, its uniqueness and why it was revoked of the prestigious planetary title. The discovery of other planetary objects in the outer solar system today known as dwarf planets made the switch of Pluto’s classification from a planet to a dwarf planet. […] Continue reading

Mini Saturn Orbiting Saturn?
Perhaps the moon in Figure 1 looks like a miniature version of Saturn. Maybe even an empanada. Saturn’s innermost moon Pan was first identified in 1990 in a photograph captured by the Voyager 2 spacecraft (which flew in 1981). Pan has an average diameter of 17.6 miles and orbits about 83,000 miles apart from Saturn. […] Continue reading
