What’s Next?

While I’ve always been vaguely interested in astronomy, before taking this class some part of my brain assumed we had somewhat stagnated on space exploration. This is largely because I knew other stars and galaxies were so far away, and we just don’t have the technology to travel to them. Ultimately, this class helped me […] Continue reading

Where Are All the Aliens? Potential Solutions to the Fermi Paradox

In class, Dr. G mentioned a Wait But Why article about the Fermi Paradox. I absolutely love this article and the entire concept of the Fermi Paradox–I even wrote about it in my Common App essay four years ago! The Fermi Paradox, first informally presented by physicist Enrico Fermi, describes the apparent contradiction between our […] Continue reading

Post 8

Now that the class has concluded, I would like to reflect on astronomy and the importance of the material that we learned. Astronomy is a fascinating topic, not only because of the nature of exploring the universe, but because it has implications for nearly every other science. From studying astronomy, we make revolutions in subjects […] Continue reading

Post 7

The Fermi Paradox essentially states that given the size of the universe, there should be aliens. So where are they? This paradox is based on various estimation equations like the Drake and Seager equations, which are ways to estimate the number of other intelligent civilizations in the galaxy that should theoretically be able to contact […] Continue reading

JUICE Explorer

As discussed briefly in class, the European Space Agency (ESA) just successfully launched the Juice (formerly JUICE: JUpiter ICy moons Explorer) mission on April 14th! I had no idea this mission even existed before it was mentioned, so I decided to explore it further. The goal of this mission is focused on Jupiter’s moons. While […] Continue reading

Binary on the Golden Records

The Voyager Golden Records are the successors to the pioneer plaques in that they were launched four years later and contain more information than their predecessors. As phonographic record, there are lots of sounds and images of life on Earth contained on them, which can be read in detail here. The cover of the records, […] Continue reading

Variable Stars and change in the Night Sky

Image of Omicron Ceti (Mira) Source: Digitized Sky Survey 2 Looking up at the night sky it may seem that while the stars do move around, they remain the same brightness all year round. This was a common belief pushed by philosophers like Aristotle, believing that stars are eternal and invariable. However in 1638 Johannes […] Continue reading

The Statistics of Life

Artist interpretation of Kepler-452b, currently the most Earthlike planet discovered, which could potentially have an atmosphere and life Source: NASA Ames/JPL-Caltech/T. Pyle When faced with an effectively boundless universe, it inevitable to ask the question of how many other lifeforms are out there. In asking this question we tend to be a bit biased, looking […] Continue reading

Final Post

It has been a long and interesting semester, filled with learning about everything from the laws of gravity, to the instruments of astronomy, and even alien life. Over the course of this semester, my view of the Solar System has changed drastically, both in detail and much more generally. I’ve learned many surprising facts about […] Continue reading

Binary in the Pioneer Plaques

About the size of a license plate, the Pioneer plaques were placed on the Pioneer 10 and Pioneer 11 spacecrafts with the hopes of reaching intelligent extraterrestrial life. The two circles on the upper left of the plaque represent two hydrogen atoms, the most abundant element in the universe. If you look closely, the line […] Continue reading
