Johannes Kepler: A Sign of the Times
Today I want to talk about Johannes Kepler (Born on December 27, 1571 at 1 PM; Died November 15, 1630). Kepler was the guy who came up with the three laws of planetary motion and basically, is the reason why we know how planets orbit things today (NASA). But did you know what was going on … Continue reading Johannes Kepler: A Sign of the Times Continue reading
Historical Astronomers in Context
Tycho Brahe (Dec. 14, 1546 – Oct. 24,1601) One of Brahe’s most acclaimed achievements was the observation of a supernova in 1572. He used this event, along with a later observation of a comet, to refute the widely-accepted idea of celestial immutability. Yet Brahe’s most important contributions to astronomy existed in the seemingly-mundane. He recorded…
Of Light and Glass (Blog #2)
Humans had been studying the stars for thousands of years before the first telescopes had been invented. The naked eye was enough to understand basic astronomical phenomena in the solar system, but if we wanted understand more, the human eye would need some help. Although they were primitive and only had magnifications of around three … Continue reading Of Light and Glass (Blog #2) → Continue reading

The Life of Low Mass Stars
Birth of Star S106 IR Birth: Emerging from a cloud of gas and dust called a nebula, a star forms when gravity pulls hydrogen gas from the nebula together and spins it around at such a fast rate that it heats up. This creates what is known as a “protostar”. Once the soon-to-be star’s temperature … Continue reading The Life of Low Mass Stars → Continue reading

Historical Events [1486] Giovanni Pico della Mirandola composes his Oration on the Dignity of Man. The best known philosopher of the Renaissance, it follows that his Oration, in which he defends 900 theological and philosophical theses, is the best known text of the 15th century. His challenge for debate on these topics attracted trouble from the church in the … Continue reading Historical Astronomers in Context → Continue reading
Awaiting the next Solar Eclipse
In August, I had the great pleasure of beginning the upcoming school year in a very profound, eye opening manner: by gazing at the Solar Eclipse that radiated over the Nashville sky. This natural occurring phenomena was not only beautiful to witness, but also, it spurred my curiosity for eclipses, moon phases, and the Solar … Continue reading Awaiting the next Solar Eclipse → Continue reading

How Big is the Universe?
Studies of the cosmic microwave background by the European Space Agency (Planck space mission) have revealed what we know as the observable universe, a sphere 28 billion light-years in diameter. Although scientists have placed the Earth in an observable sphere with a radius of 13.8 billion light-years, it is believed that this radius has expanded … Continue reading How Big is the Universe? → Continue reading
Wormholes
A wormhole is a theoretical tunnel connecting two points in space-time based on the theory of general relativity. Albert Einstein, Nathan Rosen and Ludwig Flamm are three physicists credited with hypothesizing this theory, but whether we will actually find one (let alone enter it) is largely up to debate. Warmholes are theorized to “pop-up” as tiny … Continue reading Wormholes → Continue reading
