The Possibility of Life on Enceladus

Posted on April 5, 2016 by Michaela Thomas

One question that still excites both amateur and professional astronomers is the possibility of life on other worlds. Certain important elements, however, must be present in order for organic life to exist.

Dust Devils on Mars

Posted on March 15, 2016 by Gabi Grys

  The ~spooky~ imagine below is not, as one may initially believe a charcoal sketch drawing of branches against the night sky (Just me? Okay).

When the Sun Shows Off

Posted on March 15, 2016 by evinske

Here Comes the Sun, doo doo doo doo…

Posted on March 15, 2016 by Gabi Grys

Dating the Solar System?

Posted on March 15, 2016 by samihahplanet

No,  I’m not referring to taking our Solar System out to a romantic dinner and movie. What astronomers and physicists are interested in is the age of our Solar System. And given the vastness and inaccessibility of most of the Solar System, revealing the true age of it has proven to be quite the challenge. Astronomers have, however, been able to […] Continue reading →

These Are Not the Droids We’re Looking For

Posted on March 15, 2016 by evinske

Knowledge is power. We want more and more of it. It’s no surprise, then, that we see the Solar System as a well full of knowledge we’ve never encountered before. So, we send spacecrafts out into the Solar System, looking for information. We want pictures, data, surprises, and (now) sound. We’re obsessed. But we too often […] Continue reading →
