Tides+Moon…Relationship?

Posted on February 16, 2016 by segalastronomyblog

If you spend an entire day at the beach, it is pretty obvious to notice that the tide changes throughout the day. Sometimes it comes up all the way to your feet while you lay in your beach chair, while other times the tide can be so low it seems like the water is a […] Continue reading →

Hearing the Universe

Posted on February 15, 2016 by alecsolarsystem

One of the most groundbreaking theories in astronomy has just been proven with the announcement last week that gravitational waves have been detected. Einstein had predicted these waves in 1916 in his theory of general relativity, and they were only just found today using lasers, which Einstein also laid the foundation for one year later in 1917. These […] Continue reading →

Space Movies – Fact or Fiction?

Posted on March 14, 2015 by bryancm1

Our in class discussion about some space movies had me venturing down a rabbit hole about Hollywood’s misconceptions about space. The most entertaining aspect for me is how movies portray character deaths in space. Movies always find creative and dramatic ways for their characters to die in space – none of which are accurate. In […] Continue reading →

An Ode to Gravity

Posted on February 22, 2015 by matthewrbirnbaum

Oh, gravity.  You have kept me grounded my whole life.  Where ever I have traveled you have kept my feet on the ground and my head out of the clouds.  I can not see you but feel your presence in all aspects of life.  While some look to defy your laws, I look to embrace […] Continue reading →

The Potsdam Gravity Potato

Posted on February 14, 2015 by revanth111

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 […] Continue reading →

A Smiley Face in Space :)

Posted on February 14, 2015 by leedd1

A picture taken by Hubble shows what appears to be a face complete with two eyes, a nose, and a smile. The two eyes are actually galaxies while the smile is made up of curving light that forms a partial circle around the figure. However, the smile doesn’t exist. There is lots of immeasurable and […] Continue reading →

Smiling Galaxy Cluster Found in Space!

Posted on February 13, 2015 by agiantchicken

That’s some intense gravitation lensing! A cluster of galaxies was recently discovered by the Hubble Telescope (AKA, uber relevant to class!) that appears to take on the shape of a bright smiling face. The galaxy cluster, known as SDSS J1038+4849, recently had the above picture taken by said telescope. While it may appear to us that […] Continue reading →

What Would Happen Without Gravity?

Posted on February 9, 2015 by lukegchapman

Is this what the world would be like without gravity? I have always wondered what earth would be like without gravity. There is gravity on the Moon and we are weightless because we are in a constant state of free fall, not because there is no gravity. But if there was no gravity on earth,… 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 →
