Posted on February 20, 2013 by JT McJunkins

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 →

Light

Posted on February 20, 2013 by michaelglindsay

Light Light, to me, will always carry a sort of mystical quality, regardless of how great our understanding of it grows to someday be. It travels across the cosmos carrying tantalizing hints at what lies beyond our short grasp. It is the information super highway of the Universe, bringing information and description of what else […] Continue reading →

A more “earthbound” use of the Doppler effect

Posted on February 20, 2013 by astrdylan

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

Posted on February 20, 2013 by werdercj

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 →

Astronomy’s Evolving Role in Society

Posted on February 20, 2013 by werdercj

Above: Stonehenge is an ancient structure in England that was used to mark the seasons. Archaeoastronomy is the study of ancient structures in search of astronomical connections.  It shows how people in the past understood and utilized phenomena they observed in the sky.  To me, the most interesting part of this is the progression of […] Continue reading →

Plato’s Cosmology

Posted on February 20, 2013 by JT McJunkins

While Plato’s cosmology may seem odd to a modern observer, it was a carefully reasoned, innovative theory in its time. Plato departed from his predecessor’s ideas beginning with his belief in a deity. While pre-Socratic philosophers attributed orde… Continue reading →

The OWL

Posted on February 20, 2013 by marknshirleyvu

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 →

Black Hole Collisions

Posted on February 20, 2013 by marknshirleyvu

Even with little formal expertise about black holes, most people know that black holes are extremely powerful regions in space in which gravity “sucks in” everything around the black hole with no chance of escape.  Now imagine if two of these massive regions were to collide.  It is easy to infer that said collision would […] Continue reading →

Interferometry

Posted on February 20, 2013 by eaangel

The concept of interferometry is really cool to me.  The fact that multiple telescopes can be combined to make larger images makes perfect sense, but I have trouble wrapping my head around the idea that even though there are huge … Continue reading → Continue reading →
