The most surprising thing about comets I learned from Astronomy 201 is that meteor showers are actually from comets! How can that be? The […] Continue reading →

Gushing With Life

Posted on April 10, 2013 by burnspress

The search for extrasolar planets and potential for alien life is one of the hottest topics in modern science. As such, I thought it would be interesting to discuss the place that some scientists say is most likely to alien host life. Enceladus seems to be at the top of everyone’s list for alien host […] Continue reading →

On Monday, NASA announced a new project scheduled to launch in 2017: the Transiting Exoplanet Survey Satellite (TESS).  This project was selected after a three-year competition, and will use surveys covering 400 times as much sky as any past missions to discover transiting exoplanets.  This struck me as particularly significant having just studied methods of […] Continue reading →

It’s OK, Pluto, You’re Not Alone!

Posted on April 10, 2013 by zvgio

A lot of Pluto fans were really upset with Pluto’s demotion from planet to “dwarf planet” back in 2006. I mean what’s not to love about a tiny iceball on the edge of the Kuiper Belt? There is good news though. Despite Pluto’s lowly new title, at least it has some company. The IAU recognizes […] Continue reading →
