Posted on April 29, 2024 by Tejas Mahesh

Welcome to my last blog on topics related to our Solar System! It has been fun time writing random stuff running through my head and calling it a blog. Here’s another: It’s really interesting to see the connections between worlds in science fiction and worlds in our solar system. For example, let’s compare Mustafar and […] Continue reading →

Drake vs Seager Equation

Posted on April 29, 2024 by Tejas Mahesh

The Drake Equation is The Seager Equation is Dr. Drake formulated his equation a century ago (in 1951) whereas Seager formulated hers approximately a decade (the interview was taken in 2013). As we can see, there are wild differences between the two equations. Seager’s equation only deals with all the stars that we’ve observed, which […] Continue reading →

Solar Eclipse

Posted on April 8, 2024 by Tejas Mahesh

Being in Nashville, I saw a partial solar eclipse today. It was unfortunate that it was extremely cloudy. Hence, the solar eclipse showed up once in a couple minutes. The clouds proved to be an excellent source of shades. So much so, that the combination of the thick clouds and the eclipse glasses blocked out […] Continue reading →

Geological Activity Far out in the Solar System

Posted on April 7, 2024 by Tejas Mahesh

Based upon the formation and evolution of the rocky terrestrial planets, size of the planet results in whether the planet is geologically active or dead. However, the moons of Jupiter, Saturn, and Neptune are smaller in size than Earth, yet are geologically active. How come? It turns out that the magma volcanic activity of the […] Continue reading →

Why Stars?

Posted on March 5, 2024 by Tejas Mahesh

Throughout history, many civilizations have been fascinated by the stars in the night sky. But the question is why. Why have many civilizations been fascinated by stars? What makes the night sky so attractive to humans? Why did they ascribe meaning to tiny dots that shone brightly, and seemed so far away? I present the […] Continue reading →

Nuclear Fusion

Posted on March 5, 2024 by Tejas Mahesh

We know that the Sun is extremely hot. Its surface temperature is 5,500 K. Temperature is a measurement of energy. So, we know that the Sun possesses huge amounts of energy. Where does that energy come from? How does the Sun create that much energy? Through a process called nuclear fusion, the Sun manages to […] Continue reading →

Kepler’s Laws of Planetary Motion

Posted on February 13, 2024 by Tejas Mahesh

After meticulously calculating the data that Tycho Brahe collected, Kepler discovered three different laws that described how planets move. Kepler’s First Law – The planets orbit in ellipses, not circles nor epicycles. For majority of history, it was thought that planets orbit through epicycles because the orbit of the planets must be perfect. However, the […] Continue reading →

Historical Astronomers in Context

Posted on February 3, 2024 by Tejas Mahesh

Isaac Newton Isaac Newton’s major life work was his book Principia Mathematica where he detailed his three laws of motion, gravitational law and other astronomical phenomena. He also created Calculus independently of Leibniz. Using his law of gravity, he derived Kepler’s three laws of planetary motion. Historical Events and Figure Scientific Revolution: The Scientific Revolution […] Continue reading →

The Speed of Light

Posted on January 23, 2024 by Tejas Mahesh

In 1905, Albert Einstein took the first crack at the Newtonian foundational physics. In his paper on special relativity, Albert Einstein postulated that the speed of light, c, is constant in all inertial reference frames. Assume that a person on a bicycle is holding a flashlight and moving at a constant speed relative to someone […] Continue reading →
