A New Generation of US Spaceflight

A new era of spaceflight is underway in America. The Space Shuttle program was retired in 2011 and ever since, if NASA wants to send an astronaut so space, they must buy a ticket on the Russian Soyuz rocket. But this status quo of depending on another nation to carpool to space is about to … Continue reading A New Generation of US Spaceflight Continue reading

500 Days of…Solitude

European Space Agency So this piece of news is a bit old, but I think its worth talking about: we’re one step closer to intersolar travel!  I’m not talking about a probe or rover, however.  In this case I’m talking about things of a human nature.  From 2007 – 2011, in a cooperative effort between […] Continue reading

The Power of the Telescope

History The first known telescopes came into invention sometime in 1608 by Dutch glass makers who had become quite skilled in making lens. In 1609 an Italian physicist and astronomer named Galileo decided to use this invention to look into the heavens. While it was rudimentary compared to the telescopes of today, this new tool […] Continue reading

Why are polarized sunglasses helpful?

What do polarized sunglasses do differently than regular sunglasses? Polarized sunglasses affect the direction of light reflection. We know that light travels in waves in a random assortment of direction. Polarization is all of the horizontal reflection of light off of reflective surfaces. When light hits an object, it will reflect parallel to the surface. … Continue reading » Continue reading

Pink Light

There are many interesting things about light, particularly those wavelengths we cannot see.  Looking at the light coming off of the Earth, we see what looks like a black body curve, but with chunks missing where greenhouse gasses absorb light.   … Continue reading Continue reading

The Webb Space Telescope: the Future of Viewing the Past

Every time you look at the stars , you are looking back in time. The universe is a big place and light takes time to move through it, so if you’re currently admiring Polaris, the photons hitting your eyes have been traveling for about 434 years to reach you. That may seem like a long […] Continue reading

Copernicus vs. Tycho Brahe

While both Copernicus and Tycho contributed to the evolution of astronomy and the Scientific Revolution in general, the nature of their accomplishments and challenges to the status quo were fundamentally different and defined their respective reception… Continue reading

A more “earthbound” use of the Doppler effect

When I was reading about the Doppler effect in the textbook, I found it easy to visualize the way we use the Doppler effect to understand the movements of astronomical objects, but I didn’t realize that we had other uses for Doppler a little closer to home. After doing a little bit of research, I … Continue reading Continue reading

Near-Earth Objects: Experiences and Implications

Meteor trail over Eastern Russia. On February 15, 2013, two very significant astronomical events occurred unusually close to us; the highly publicized meteor explosion over a Russian city overshadowed the close approach of a much larger asteroid orbiting Earth.  The contrast between these two events is what struck me as most interesting and informative about […] Continue reading

The OWL

While reading about different types of telescopes here on Earth I stumbled across a cancelled project known as the OWL (Overwhelmingly Large) Telescope, and overwhelming might be an understatement.  This telescope, a concept developed by the European Southern Observatory, would boast a single aperture measuring 100 meters in diameter, longer than a football field! It […] Continue reading
