Bracewellvon Neumann Probes
Human space travel is slow and each mission must be meticulously planned. What if there were a way we could learn more about the universe more efficiently? John Von Neumann, in charge of computing the design of a bomb, wondered how else he could use his computing skills. He developed the idea of self-reproducing automation. […] Continue reading

Blog #7: Sara Seager Ted Talk
I watched the 2015 Ted Talk from Sara Seager (of the Seager Equation) called The Search for Planets Beyond our Solar System. She sets out to introduce what we currently know about our solar galaxy and extra solar planets. She presents a few interesting artist conceptions of the various exoplanets we know of (mainly from […] Continue reading

Where Are the Aliens?
Based on various calculations and estimations made by scientists all over the world, there is a very high probability that aliens (i.e. life elsewhere in the universe) exist. However, we have never encountered any tangible or irrefutable evidence of aliens. This contradiction is called the Fermi Paradox. One possible explanation for this paradox is that […] Continue reading

Extremophiles
The word extremophile comes from the Latin words extremus (meaning extreme) and philia (meaning love). An extremophile is an organism with the ability to survive, or even thrive, in an environment that we as humans would consider extreme. These organisms are some of the oldest species to exist on Earth. Some of them date back […] 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…

Exoplanets
The words in the above picture are hard to make out, but I really liked the visual of some of the known exoplanets graphed on a plot. The color and appearances of these planets are not truly known since we have not directly seen them, but they are inferred based on density, temperature, metal content, […] 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
