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 → Continue reading
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 → Continue reading
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 → Continue reading
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 → Continue reading
Even though we are the most familiar with planets within our solar system, there have been many discoveries of exoplanets with the development of scientific technology and the improvement 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 → Continue reading
Once thought as the 9th planet of our solar system, Pluto is a dwarf planet and is part of the Kuiper belt. The first discovery of this dwarf planet was in 1930 by Clyde Tombaugh. Until 2005, Pluto was considered as the 9th planet of the solar system. However, as another dwarf planet called … Continue reading Pluto and its interesting property. → Continue reading → Continue reading
Surprisingly, our galaxy, Milky Way is expected to have a collision with another galaxy, called Andromeda. Even though the universe is expanding at every moment since its creation, the 2 galaxies, Milky Way and Andromeda are coming close to each other with an anticipated collision in about 4 billion years. Both galaxies are located … Continue reading Milky Way and Andromeda Collision → Continue reading → Continue reading
Astronomers have discovered an enormously massive galaxy, NGC 1600, 209 light years away. NGC 1600 is an elliptical galaxy that is 17,000,000,000 billion solar masses. There are many massive black holes in the Universe (Source). In fact, there is a black hole at the center of every galaxy. It is thought that perhaps black holes […] Continue reading → Continue reading
Chapter 1 of Astronomy: The Solar System served as a HUGE (seriously though) reminder as to how small and insignificant we are, and how very very very infinitesimally small the corner of the universe we’ve explored actually is. I’m a big Star Wars fan, and looking at that world from the perspective of astronomy class, […] Continue reading → Continue reading
The Milky Way Galaxy So, I’ve spent 4 months learning about the solar system and how everything works so perfectly together. When I started astronomy it was just because I needed a technical elective; however, it gave me a lot of perspective. Our world is in the perfect placement in a 100,000 light-year galaxy to… Continue reading → Continue reading
