How do we discover Exoplanets?
Depiction of Astrometry For this blog I wanted to look into exoplanets and more specifically how we discover them. I found that there are 4 main methods to discover exoplanets. The first is the radial velocity method. This is how many of the first exoplanets were discovered. This method observes the doppler shift in the […] Continue reading

Protecting Our Home
History is doomed to repeat itself. Will we be ready? Around 66 million years ago, an object estimated to be around 10km wide struck Earth at incredibly high speeds. The energy released was equivalent to roughly 100 million megatons of TNT. The impact, then, released over 6.5 billion times more energy than the catastrophically powerful […] Continue reading

Blog SOLAR ECLIPSE
Today was the day, I saw the eclipse. It was amazing, and truly a piece of art. There were lots of clouds and I was barely able to see the eclipse although when seeing it, it was eye burning. Literally. As I had no glasses, I took a video of it that I am very […] Continue reading
bLOG 6: HOW MUCH DOES SIZE MATTER (FOR VOLCANISM and CRYOVOLCANISM)?
Even some of the smallest world in our solar system exhibit (or have exhibited) evidence of volcanism or cryovolcanism. Asteroids like Vesta, with radii of only several hundred kilometers, displays features that indicate that they once exhibited active volcanism and even separation by differentiation. Although their volcanism lasted for periods that were geologically very brief, […] Continue reading
Robert Navarro, Blog Post 05 FUN FACTS ON PLUTO
Pluto’s as a planet is very intriguing. Despite being located far from the Sun; Pluto has seasonal changes due to its tilted axis (just like earth!) and highly elliptical orbit. When Pluto is closer to the Sun in its orbit, the frozen nitrogen, and methane on its surface can temporarily sublimate, creating a thin atmosphere. […] Continue reading

Composition -The solar system is primarily composed of the Sun, which makes up about 99.8% of its total mass. The Sun is primarily composed of 74% hydrogen and about 24% helium with some amounts of heavier elements. Planets in our solar system are divided into two main groups based on their composition: the terrestrial planets […] Continue reading
Understanding Auroras: The Physics of Earth’s Magnetic Light Shows
The Northern Lights The northern lights, or aurora borealis, is a display of natural light that occurs in the Earth’s sky. What you might not know is that there is another light show on Earth called aurora australis, which occurs in the southern hemisphere. So, what causes these natural and captivating lights? Solar winds are […] Continue reading
The Role of Radioactive Decay in Earth’s Internal Heat
Image: Cross Section of Earth As we have learned, the cause of seasons is the directness of sunlight a particular region of the Earth receives. What you may not know is that the sun is not the only source that heats up the Earth. The Earth actually internally generates its own heat through radioactive decay. […] Continue reading
Nature’s Closely Guarded Secret – Nuclear Fusion
We are, quite literally, made of stardust. Stars are the birthplace of many of the elements that make up our physical reality as we know it. Heavier elements (heavier than Iron, specifically) were created in a Supernova — a violent explosion of epic proportions at the end of a massive stars life. Inside of every […] Continue reading
