The Complex Chemistry of Titan
A recent experiment by NASA’s Jet Propulsion Laboratory simulating Titan’s atmosphere has shown that there is some exciting chemistry going on not only in it’s upper atmosphere, but in the lower atmosphere too! Before this, scientists had assumed that as you got closer to the surface, the air became “dull and inert.” However, this team […] 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
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
Chemical Activity on Titan
Scientists at NASA now believe that Saturn’s moon Titan is much more chemically active than we previously thought. According to Astronomy Magazine, the found that the “complex organic chemistry that could eventually lead to the building blocks of life extends lower in the atmosphere than previously thought.” This is activity in the lower atmosphere […] Continue reading
The Galilean Moons of Jupiter
With the constant discovery of more and more objects in space, it is difficult to keep track of the planets, moons, asteroids, comets, and exosolar planets that we already know and love. Therefore I am using this blog as an … Continue reading → Continue reading
Why is Europa so Awesome?
A lot of the science community is excited about the possibility of life of Mars. But, as we know, the vast majority of Mars’s atmosphere is composed of carbon dioxide and what water it does have is frozen in its polar ice caps. An arguably much more exciting destination in our own Solar System is […] Continue reading

GRAIL Maps the Gravity of the Moon
Twin NASA probes orbiting the moon for the Gravity Recovery and Interior Labority (GRAIL) mission have created the most highly detailed gravity field map of any celestial body. Pictured above, this map reveals an abundance of features includ… Continue reading

Life On Titan?
We may not have to look very far from our solar system for habitable worlds that can sustain life. We already know that Mars had conditions suitable for life in its early years and there is a possibility that Venus might have been the same way. But scientists are now excited about the possibility that […] Continue reading
The Little Solar System that Could
Pluto may no longer be a planet, but it sure is proving to be one of the most interesting objects in our solar system. We’ve kicked it out of the planet club, but Pluto seems to have plenty of friends of its own, with scientists thinking the little dwarf planet could have 10 more moons […] Continue reading

Once in a Blue Moon?
While studying lunar phases for tomorrow’s test, I wondered what the common phrase “Blue Moon” meant. According to Wikipedia, Blue Moon is a term used to describe the second full moon in one month. A two-full-moon month occurs approximately once every 3 years, and the it can only occur is because most months (with the […] Continue reading
