I will never know if the Earth was a fluke

Posted on April 29, 2015 by farhannshabab

I had taken Astronomy 201 because I was curious about humanity’s place in the universe. As a second semester senior, I didn’t need this class at all; I just wanted broaden my understanding of the world around me. Deep down, I also wanted form an educated opinion on the possibility of extraterrestrial life. It was hence […] Continue reading →

To Go Boldly Where No (Hu)Man Has Gone Before: The Future of Space Exploration

Posted on April 19, 2015 by alyssasolarblog

In the 1960’s, Star Trek popularized the idea of outer space as the “final frontier”. However, exploration of space is about as final as the possible values between .99 and 1: the possibilities are limitless. Here are few of the most exciting forthcoming explorations of this infinite final frontier: NASA’s Journey to Mars– NASA plans … Continue reading To Go Boldly Where No (Hu)Man Has Gone Before: The Future of Space Exploration → Continue reading →

Are You There, Universe? It’s Me, Earth.

Posted on April 19, 2015 by alyssasolarblog

In 1974, to celebrate the remodeling of Puerto Rico’s Arecibo radio telescope, the Arecibo message was sent toward the globular star cluster M13 (located 25,000 light years away from our sun) through radio waves. The message was written by Dr. Francis Drake (of the Drake equation) and Carl Sagan, among others. Aimed at other civilized … Continue reading Are You There, Universe?

Planet Discovered with Four Parent Stars

Posted on April 6, 2015 by conorastr201

Binary star systems, like the one featured in the Tatooine system of Star Wars are common in the universe with half of all systems being comprised that way. Ternary system, or systems with three stars, are more rare, and even more rare are quaternion systems. Planets within these four star systems are also rare, so much so […] Continue reading →

Predicting Impact Events

Posted on April 4, 2015 by alyssasolarblog

In 1994, Comet Shoemaker-Levy 9 created a large impact event on Jupiter, giving the scientific community a greater sense of urgency in detecting possible impact objects before they reached Earth. These efforts to detect near-Earth objects, known collectively as “Spaceguard”, have enjoyed both successes and failures. For example, in 2008, the Catalina Sky Survey discovered … Continue reading Predicting Impact Events → Continue reading →

Orbital Resonances: They Space Out the Solar System

Posted on April 3, 2015 by alyssasolarblog

In class we learned that the divisions in Saturn’s rings are caused by orbital resonance. Orbital resonance is a phenomenon in which “two orbiting bodies exert a regular, periodic gravitational influence on each other,” usually because their orbital periods “match up”. For instance, if particles were in Saturn’s Cassini division, they would orbit twice for … Continue reading Orbital Resonances: They Space Out the Solar System → Continue reading →
