Astrophysics

How I became interested in astrophysics.

I first got interested in astrophysics from watching Neil deGrasse Tyson clips and reading several of his books. The way he talks about the universe made me want to learn more and start asking questions of my own. One of the first was: if the universe is 13.8 billion years old, how can the observable universe be nearly 100 billion light-years across if nothing can travel faster than light?

Learning beyond school

Turning an interest into actual work.

University of Washington Astronomy 101

I took UW Astronomy 101 and finished with a 98.54%. The class gave me a much stronger foundation in the science behind the things I had already been curious about.

Washington Aerospace Scholars

Washington Aerospace Scholars is a year-long course that runs throughout the school year and focuses on aerospace, Earth and space science, and the work behind real space missions. The course combines research, math, writing, and design with interactive group projects.

Astrophotography

The visual side of astronomy.

A lot of my interest in astronomy comes from the math and physics. Astrophotography lets me approach the same subject visually. When I photograph a nebula, galaxy, star cluster, or the Moon, I am thinking about what it is and how it works, but also about color, framing, and what makes the image worth looking at.

Something I built

Orbital Sandbox

I made Orbital Sandbox because I was tired of working through every orbital calculation by hand. It does the calculations instantly, so I can change a spacecraft's position or velocity and see the result right away.
