Diversity of Telescopes

There is such a diverse range of telescopes accessible to consumers around the world. Of course, these telescopes are not of high quality in terms of magnetization and clarity. However, comparing accessible telescopes to high-powered, extremely large telescopes that have entire buildings designed to contain them is not impossible, but seeing as these large telescopes… Continue reading Continue reading

Celestial Navigation

Navigational Compass used in Ming Dynasty      image source Before the invention of artificial satellites and development of data transformation, celestial navigation played an indispensable role in human’s exploration and discovery of newfound lands. And in this blog, I would like to introduce some celestial navigating technologies implemented in Zheng He’s treasury voyage, one […] Continue reading Continue reading

Negative Energy (Gravity)

When one considers that amount of energy that occurs from splitting a single atom, and then multiples that by the 10^80 particles that exist in our universe, one might conclude that the net total of energy in the universe is a astronomically large. Surely beyond anything a human mind could comprehend. The reality however is […] Continue reading Continue reading

Out of this World Symbols

Astronomers, like all scientists, love their symbols. Why spend ages written out full text when shorthand will do? Not only  are the symbols for the planets convenient, they also have interesting stories behind them that tie into the planet’s history. Sun: The symbol for the sun is a circular shield with a dot in the […] Continue reading Continue reading

The Effect of Living in Space

While I think that studying space and astronomy is super awesome, I honestly am not sure I can imagine anything worse than living in space for an extended period of time. As we discussed in class, living in space (or at least in orbit) is essentially like being in constant free fall. You know that stomach […] Continue reading Continue reading

Project Orion: Riding Atomic Explosions into Space

From the LSD-laden project MK Ultra to the ill-fated foray into psychic warfare that was Stargate Project, the U.S. government has sanctioned some truly strange studies over the past century. But one research endeavor stands out among all the others throught its sheer magnitude, ridiculousness, and surprising potential. I am talking, of course, about Project Orion. […] Continue reading Continue reading

How Gravity Affects Space-Time

One of the more interesting (and more confusing) concepts we’ve learned thus far in the Solar System is the bending of spacetime. As can be seen in the figure below, massive objects with gravity (such as planets or stars) have the unique property in that they can bend the spacetime “grid” around them. Before you […] Continue reading Continue reading

The Sun’s Absorption Spectrum

Absorption spectra occur when a hot solid or liquid or very dense gas give off a continuous spectrum, with all colors, and then that continuous light moves through a thin gas that is cooler than the source of the continuous light. This thin gas absorbs some of the light being given off by the source […] Continue reading Continue reading

love is in the spacetime

gravity has found itself grounded in a great deal of pop culture recently. from depictions in cinematic blockbusters to the recent historic breakthrough at LIGO, gravity has become somewhat of a household/cocktail party topic of conversation. being a physics major, over the years i’ve come to think of cosmological things in visuals, or colors, or little … Continue reading love is in the spacetime Continue reading Continue reading

Lunar and Solar Tides

Tides are a fascinating effect of the Moon and Sun’s gravitational forces acting on the Earth. They are a visible sign of how distance effects the strength of a gravitational force. Because the Sun is so large, it has the greatest gravitational force acting on the Earth. However, because it is so far away, the […] Continue reading Continue reading
