Blog Post 8: How astro2110 Has Changed My View On Astronomy
Before coming into astro2110, I knew very little about astronomy. Now, after completing the course, my appreciation for astronomy has greatly increased. A few days before the semester started, one of my friends who is an astronomy nerd laughed at me for not knowing the phases of the Moon. I thought to myself, “I’m a […] Continue reading
Where Are the Aliens?
Based on various calculations and estimations made by scientists all over the world, there is a very high probability that aliens (i.e. life elsewhere in the universe) exist. However, we have never encountered any tangible or irrefutable evidence of aliens. This contradiction is called the Fermi Paradox. One possible explanation for this paradox is that […] Continue reading

The Andromeda Galaxy is one of the only galaxies visible without the aid of a telescope on Earth. It is a spiral galaxy, and it got its name because it is located in the constellation Andromeda. It is approximately 2,480,000 light years from Earth and has a diameter of approximately 200,000 light years. The first […] Continue reading

Galactic jet lag
In class, we discussed the implications and mechanics of light travel time. A major takeaway was the concept that because of the incredibly fast yet undeniably limited speed of light we are able to see VERY distant objects as they were VERY long ago. If you are like me, you might try to see what … Continue reading Galactic jet lag Continue reading
The aliens in Starcraft.
When it comes to how creative and bright people are at imagining aliens in the universe, some people would think of Star Trek, Star Wars, and Alien: Covenant. In these creative movies, some aliens are portrayed as gross, primitive monsters that kill and eat humans while others are portrayed as friendly, intelligent creatures. About 20 years ago, … Continue reading The aliens in Starcraft. → Continue reading

Interesting facts about Fermi Paradox
In respect to one of the most controversial question, “whether extraterrestrial lives exist in the universe,” we often assume there is high probability that such alien lives exist somewhere. Because there are 70 sextillion stars and numerous earth-like planets along with the stars in the observable universe, we often think that some intelligent forms of … Continue reading Interesting facts about Fermi Paradox → Continue reading

Missing Dark Matter
There is an understanding that about 80 percent of the mass in the universe is made up of material that we cannot observe, and that matter is called dark matter. Although there is no direct evidence of dark matter, it must be present to hold the elements of the universe together. Recently, it was discovered … Continue reading Missing Dark Matter Continue reading
Many interesting exoplanets.
Even though we are mostly familiar with planets within our solar system, there have been many discoveries of exoplanets with the development of scientific technology and the improvement of our understanding of the Universe. Among these exoplanets, there are some interesting and habitable planets outside our solar system. First of all, “Kepler-186f” was found to … Continue reading Many interesting exoplanets. → Continue reading
