My Introductory Post

Posted on January 13, 2015 by ctogrye

Hey there, This is the first test post Dr. G asked me to put up. I attached a picture of the Pound-Rebka experiment because I’m a physics major and it seemed to tie into an astronomy class (with verifying gravitation redshift and such). Continue reading →

The origins of life and the Drake equation

Posted on April 28, 2014 by Drew Hamilton

In using the Drake equation to discuss and estimate the probability of non-Earth life in our universe, one factor we estimated was the probability of life developing on a given planet in the habitable zone. The problem with making such an estimate as students in an Astronomy 201 course, of course, is that we all… Continue reading →

Standing on the Shoulders of Giants

Posted on April 28, 2014 by jblubin

“We are a way for the Cosmos to know itself,” said Carl Sagan.  Astronomy is not only the oldest science, but also a window through which mankind peers through in attempt to glimpse the fleeting answers to our deepest and most fundamental questions. As a direct result of the this class, I find myself looking … Continue reading Standing on the Shoulders of Giants → Continue reading →

Metallic hydrogen

Posted on April 9, 2014 by Drew Hamilton

In learning about the interiors, we’ve heard a lot about metallic hydrogen. To me, it was a confusing idea, simply because I only really hear about hydrogen in the context of being a gas or being a compound such as water or methane. Furthermore, it was not clear what phase metallic hydrogen would be, since… Continue reading →

The definition of “planet”

Posted on April 8, 2014 by Drew Hamilton

Ever since the IAU gathered in Prague in 2006 and published a new scientific definition of “planet”, there has been debate on how well they did, and whether they were right to “demote” Pluto from planet to the new “dwarf planet” classification. I aim here to critique the IAU’s definition of a planet. First, here… Continue reading →

80% of the Universe That We Can’t See

Posted on April 8, 2014 by joshkphilips

Image Source Over the past couple of centuries, we have learned a great deal about our Universe. However, the more we seem to learn about the cosmos, the more we realize that we do not understand. When Jan Oort and Fritz Zwicky first hypothesized the existence of dark matter in our Universe, a breakthrough in […] Continue reading →

Jupiter: Magnetosphere Explained

Posted on April 7, 2014 by joshkip

One feature of Jupiter that may come as a surprise is that it contains a magnetic field more than 20,000 times as strong as that of Earth’s. But, how is this possible if the Gas Giant is comprised of only … Continue reading → Continue reading →

Lagrange Points

Posted on April 6, 2014 by gradytlynch

This video by Sixty Symbols gives an in depth look at lagrange points, delving into the physics of orbiting bodies. The video outlines the five lagrange points of the Earth-Sun system. L1 is between the Earth and Sun, L2 is slightly farther from the Sun than Earth, and L3 is on the opposite side of […] Continue reading →

Edmond Halley: Proving Newton

Posted on March 29, 2014 by jblubin

Newton was the first to provide a mathematical construct to describe the effects of planetary motion around the Sun. But then the question arose, how could we find evidence for the theory? Stepping up to the plate was the prominent astronomer Edmond Halley. Born in the English countryside on November 8, 1656, Halley was a … Continue reading Edmond Halley: Proving Newton → Continue reading →

The way of the future

Posted on March 18, 2014 by blakestar2k14

Nuclear Fusion has always been the process known to heat the sun and produce the light that we so desperately depend on. Only until recently, has the possibility of being able to harness the incredible power of nuclear fusion becoming a possibility. The ultimate goal behind this groundbreaking research is to be able to create […] Continue reading →
