Blog #8 – Black Holes and How to Find Them
Black Holes are quite a popular topic in astronomy, but I still would like to talk about them for my last post, since they are truly revolutionary. Black Holes, in short, are gravity’s ultimate victory over stars. After a star supernova explosion, the core of a star remains. But if this core weighs more than […] Continue reading
Blog 7 – The Fermi Paradox
When learning astronomy, one often wonders if humanity is alone in the galaxy. Physicist Enrico Fermi pondered this question, and ultimately came to a rather profound conclusion. Statistically our galaxy should be home to at least a handful of advanced societies more than capable of interstellar travel, so why have we not encountered any? Fermi […] Continue reading

The Cosmic Microwave Background
One of the pillars that the Big Bang Theory Model rests on is the existence and characteristics of the Cosmic Microwave Background (CMB). The CMB is an observed cosmic glow of radiation seen everywhere, filling the universe like a sea. Roughly 380,000 years after the Big Bang, the universe cooled enough (~3,000K) for free-roaming electrons […] Continue reading
Bog 5 – Chelyabinsk Meteor
A relatively recent and frightening meteoric event occurred in the quaint city of Chelyabinsk in Russia on February 15, 2013. This incident is rather interesting since damage caused by the meteor was not due to impact, but rather violent shockwaves produced by the airborne-meteor’s explosion over the city. The explosion occurred when the meteor, roughly […] Continue reading
Blog #4 – Evidence for the Existence of Dark Matter
Dark Matter is a fascinating topic, yet we know so little about it. Regardless, a good amount of evidence exists that indicates dark matter is real. One pertains to the flatness of rotation curves for spiral galaxies at extended distances. The graph does not drop off, but rather, continues in (essentially) a flat rotation curve, […] Continue reading
Blog #3 – Theories For the Sun’s Energy Source
Many scientific theories attempted to explain the source of the Sun’s energy, and the very first hypothesis involved some explanation pertaining to chemical reactions and gravitational collapse. Chemical burning, however, was ruled since no chemically burning substance like wood or gasoline can account for the Sun’s enormous luminosity. As for gravitational collapse, the conversion of […] Continue reading
Blog Post 2 – The Doppler Effect
Most people have already heard of the Doppler Effect, an interesting phenomena of sound that alters the pitch of moving objects depending on their direction. The Doppler Effect functions similarly by affecting the shifts of light wavelengths. When, for example, a planet is moving toward us, its light waves will be clumped together and appear […] Continue reading
Historical Astronomers in Context – Isaac Newton
Isaac Newton was born on January 4, 1643 and died on March 31, 1727. He contributed immensely to the study of astronomy, as he invented the reflecting telescope, calculus, and the theory of gravitation. His contributions to both science and mathematics truly bolstered the pursuit of astronomy and cemented him as one of, if not, […] Continue reading

Blog 1 – The “Great American Eclipse” Experience
Back in 2017, my school allotted class time for observing the total solar eclipse that (conveniently) passed through Nashville. Many of my classmates (including me) didn’t fully realize how significant this was until our observation. The brief two and a half minutes of totality was awe inspiring. What struck me most was the terrestrial reaction […] Continue reading
Blog 0 – Introduction
I was outside with my dad and brother a couple of weeks ago and saw this moon. Thought it looked cool so I took a grubby photo with my phone. Some info on the phases of the moon.
Outstandingly High Quality Image by me
