The Scale of the Universe and Us

Posted on January 22, 2023 by cuia2

     Reading the graphic in the textbook called “Our Cosmic Address”, I got a sense for the first time of how small of a planet we live on. Earth is a typical planet rotating by a typical star we call the Sun which is only one of billions of stars in the Milky Way which is […] Continue reading →

Minutes and seconds of arc

Posted on January 22, 2023 by Andrew Cascio

Similar to a light-year, an arcminute can be mistaken for a unit of time. An arcminute is 1/60th of a degree and an arcsecond is 1/60th of an arcminute. For example, “12 degrees, 50 arcminutes, and 29 arcseconds” is written as 12° 50′ 29”. As units of angular measurement, arcminutes and arcseconds allow for more […] Continue reading →

Solar Eclipses 😱😎

Posted on January 22, 2023 by sadiekarr

(Eclipse over Jackson, Wyoming by Ronan Donovan via NatGeo) In August 2017 a total solar eclipse was witnessed by many, cutting across the United States. My family, here in Nashville, TN, was able to see it! Even though it was a Monday, and I should have had classes, my school was cancelled for the day […] Continue reading →

Blog One – Night Sky Observing

Posted on January 21, 2023 by 7smessier45

In my first post, I briefly mentioned the international dark sky association. This association advocates for the protection of the night sky by leading the fight against light pollution through their efforts at the grassroots up to the international level.  Although cultures around the world have looked up at the night sky for millennia, in […] Continue reading →

Legitimate and Illegitimate Cases of Exceeding Light Speed

Posted on January 21, 2023 by 88bw

This image of CERN provided by TIME was taken at the peak of the 2012 craze over the facility’s discovery of neutrino particles breaking light speed. Since the barrier of light speed has been such an insurmountable rock and cornerstone of physics, the neutrino’s clocked speed increase of 0.0025% was groundbreaking. Although I was only […] Continue reading →

Identifying Jupiter and Mars

Posted on January 21, 2023 by Europa

Last night, I was looking up at the night sky while walking to dinner. I noticed a few constellations, as well as two brighter points of light that I was pretty sure were Mars and Jupiter. Normally, I can identify them, but for some reason Mars didn’t look as red to me as it normally […] Continue reading →

The Upcoming Total Solar Eclipse

Posted on January 20, 2023 by sydneyastr2110

One year, two months, and eighteen days: this is the time from the writing of this blog until a total solar eclipse will occur in North America. I’ll save you from doing the math, the date of this solar eclipse is April 8, 2024. The sky along the path of totality will become dark for […] Continue reading →

Moon Phases in the Southern Hemisphere

Posted on January 18, 2023 by willems49

While reading Chapter 2 in the textbook, I realized how much of a difference living in the southern hemisphere would affect the way you view space. I think we generally tend to think of things as being similar if not the same in the southern hemisphere, especially something as universal as the stars in the […] Continue reading →

blog post 07

Posted on May 4, 2022 by graceward02

The Fermi Paradox is the conflict between the lack of evidence of extraterrestrial life and high estimates for its existence. The main explanation people have come up with for this paradox is that intelligent life is rare. Using this explanation, it makes sense why there would be many places with rudimentary life, but without intelligent […] Continue reading →

Wrapping Up Solar System

Posted on May 4, 2022 by isaiandrade01

One of the biggest takeaways I have from the Solar System course is how different perspectives can be, and how they can really shape the way we think about not only space-related topics but life in general. The picture above is a prime example of perspective as almost everything we know about space is viewed […] Continue reading →
