Extremophiles: life finds a way
I remember first learning about extremophiles back in the sixth grade. Back then, I was fascinated by life’s ability to find a way to survive even in the ‘worst’ conditions. Now that I’m older, I am no less fascinated by these amazing organisms, their ability to thrive, and their connection to astronomy. (I only recently […] Continue reading

Life on Europa?
There is life in all forms throughout the world. Even in the most remote places with the most extreme conditions we have seen life not only survive but thrive. This makes us wonder, could there be life on possible habitable worlds? NASA put this to the test by conducting an infrared (IR) signature of oneContinue reading “Life on Europa?” Continue reading

Life on Earth
In my last blog post I would like to discuss some of the things I’ve found most interesting in the course of the semester. As this class has come to an end, I’ve found myself more and more astounded by how our Solar System formed than ever before, specifically the ability of Earth to sustainContinue reading “Life on Earth” Continue reading
The Fermi Paradox and the Great Filter
According to Kardashev scale, proposed by astronomer Nikolai Kardashev, there are three types of civilizations. Type I has the ability to use the energy of their planet, Type II can use the energy of their host star and Type III can access an amount of power comparable to an entire galaxy. Based on the extremely largeContinue reading “The Fermi Paradox and the Great Filter” Continue reading

New Horizon’s Approaches Pluto: So What?
NASA’s New Horizon’s spacecraft is only three months approaching Pluto, and for the first time, we have a true color picture of the Pluto/Charon dwarf planet system. As I sit here typing this, I say, “so what?” Well, it turns out that this is the first time that any spacecraft has traveled so long and […]

NASA’s NExSS Project to Lead the Way for the Search for Alien Life
NASA is currently assembling a group that it plans to call the Nexus for Exoplanet System Science (NExSS), which will be a group of specialists from various scientific fields in hopes to study the nature of exoplanets and figure out if some might be suitable for life. Currently the project has garnered support among planetary and […]

Europa Report
This past weekend, I watched a movie on Netflix called Europa Report. The movie was a detailed the gripping journey of six people on their trip Europa with the sole mission of confirming or denying the existence of life on Jupiter’s moon Europa. Not only was this a great, well done film, but it also touched on […]

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 […]
