Drake Equation: Quantifying Extraterrestrial Life
Hey Everyone, Today I’m going to discuss a major concept in the search for extraterrestrial life. Specifically, I will be discussing the Drake equation and its impact on said search. The Drake equation is an equation designed to approximate the number of extraterrestrial civilizations that exist in the Milky Way. It was developed by Frank Drake […]

Spectroscopy and the identity of elements
Hey Everyone, Today I am going to discuss the details of spectroscopy which explain why different atoms and molecules have different characteristic emission and absorption spectrum. The reason for this unique patterns lies with the the atom’s (or molecule’s) electron energy levels. Each atom and molecule has a unique separation of electron energy levels which […]

How special is the Milky Way?
The Milky Way is the first galaxy that we call home since the beginning of the human race and it is very likely also the last. We know earth has many rare qualities that made life possible, looking on a larger scale, is our galaxy also a unique snowflake like our planet? Using data collected from the Sloan … Continue reading How special is the Milky Way? → Continue reading

Things aren’t always as they appear on the surface
When one looks at the great expanse of the Universe, they will see a mix of moons, planets, stars, and galaxies, but what about all of the open “space” in between these celestial bodies? Most are familiar with the fabric of space-time, which is best described by general relativity, as it illustrates in a logical […]

The Potsdam Gravity Potato
Source: Universe Today The above picture is a rendering of the Earth’s gravitational field produced by the German Research Center for Geophysics’ Helmholtz’s Center in Potsdam, Germany. Known as the “Gravity Potato,” it shows that the Earth’s gravity is not as uniform as one would think. In fact, the gravitational force is a dynamic surface that […]
