Tardigrades are the toughest animals that we have yet discovered, not due to their physical strength, but rather their incredible ability to survive. People praise cockroaches for their ability to survive levels of radiation that would be lethal to humans, but the real heroes are microscopic “water bears” called tardigrades. Tardigrades are extremophiles, or micro-organisms … Continue reading Tardigrades Continue reading → Continue reading
The string theory is a very interesting idea that propose another totally different way of thinking what made up our universe. Although this theory is very arguable because it can never be tested in our labs so that a lot of physicist do not like this theory, but it indeed gives a very unique prospective … Continue reading String theory – the other way of interpreting our universe → Continue reading → Continue reading
With a recent picture of a blackhole becoming the newest internet sensation I thought it might be neat to talk about my favorite word, spaghettification. In class we’ve talked about tidal forces, that is the force differential between the close part and the far part to a gravitational source. On the small scale, such as … Continue reading Speghettification Continue reading → Continue reading
For this blog post, I ventured onto YouTube to find a more detailed explanation of the Fermi Paradox. Although there we a video by celebrity scientist Bill Nye on YouTube, I ventured for a more scientific video done by Kurzgesagt – In a Nutshell. The video introduced three categories of civilizations. A type one civilization … Continue reading More on the Fermi Paradox → Continue reading → Continue reading
What a ride this class has been! The sheer amount of new topics and discoveries I learned about is ridiculous, but my favorite has definitely got to be regarding the unknowns and potentials for life in our universe, or even our own Solar System! Learning about worlds such as Europa and Titan, and the liquid … Continue reading The End of a Course, But The Start of a Passion! → Continue reading → Continue reading
The Fermi Paradox is a complicated contradiction that considers the probability that other life in the Universe exists, and asks why we have never encountered it. Essentially, some calculations were made to suggest with a high probability that there are many worlds in our universe and even solar system that are habitable, and that the … Continue reading Where are they?

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
In the center of the galaxy M87, stars seem to orbit an invisible object. By observing the path of the stars, scientists concluded that there is a supermassive black hole that is dense enough to cause these motions. Although the black hole itself is invisible, we can still observe the ring of light bended by … Continue reading Hello Powehi → Continue reading → Continue reading
Extrasolar planets is one of the most interesting astronomical research topics. It can help us answer questions such as whether there are aliens, or is it possible for us to find another “Earth” to live on. An extrasolar planet is defined as a planet that is outside of solar system. The history of extrasolar planet … Continue reading Extrasolar planets — Earth-like planets → Continue reading → Continue reading
In 2061, Halley’s Comet will return to pass by Earth in 75-year long round trip across the solar system. But what else do we know about this mysterious visitor? Studying the reports of comet sightings in 1531, 1607, and 1682, Edmond Halley deduced that these comets were in fact the same one and that it … Continue reading Halley’s Comet → Continue reading → Continue reading
