Despite evidence that suggests that there should be extraterrestrial civilizations, we have not yet detected any signs of these civilizations. This issue is called the “Fermi Paradox,” after Enrico Fermi—a Nobel Prize-winning physicist. Compared to the lifespan of the universe, our sun is relatively young at 4.6 billion years old, so there are older stars […] Continue reading → Continue reading
The New Horizons space probe was launched in 2006—primarily to study Pluto, but also to study Kuiper belt objects in its following years. Following the space probe’s flyby of Pluto in 2015, it reached 2014 MU69, also known as Ultima Thule, on January 1, 2019. Ultima Thule is a Kuiper belt object that orbits 1.6 […] Continue reading → Continue reading
In 2003, NASA launched the Mars Exploration Rover mission, dropping the Spirit and Opportunity rovers on Mars in January 2004. Although their planned mission lifetime was 90 days, both rovers far exceeded this. Spirit lasted 20 times longer than this, traveling almost 5 miles before sending its final message to Earth on March 22, 2010. […] Continue reading → Continue reading

Although his own model of the solar system proved to be inaccurate, his observations provided important information that set the foundation for future astronomers to construct more accurate models. … Continue reading Tycho Brahe in Context → Continue reading → Continue reading
When it comes to taking meaningless BuzzFeed quizzes or looking at Tumblr text posts about my zodiac sign, I am guilty as charged. There’s something satisfying about taking a quiz that tells you which limited edition Oreo flavor you are by your zodiac sign! (I’m apparently Gingerbread. Who knew?) I even know some people who … Continue reading Earth’s Precession: Why Your Zodiac Sign is Wrong → Continue reading → Continue reading
I’m Victoria, and I’m a sophomore from East Tennessee. This blog is for Astronomy 2110: The Solar System. I’ve taken the stars and galaxies lecture, as well as Astro lab (where I learned that because of Earth’s precession, I’m not actually a Libra…), so I am excited to learn more about astronomy this semester!
