Blogging for Vanderbilt Astronomy class! For my 2018 class.

In looking at what planets can sustain life, one requirement always includes liquid water. Which is the region surrounding a star capable of supporting liquid water. But are we limiting ourselves too much in our searches? What if life was capable of developing without this basic requirement? A team of researchers.

Astronomy class and stuff! Doctor Who is not COMPLETELY fictional. Doctor Who is not COMPLETELY fictional. The article above confirms my hope! April 23, 2015.

Blogging about my Astronomy class at Vanderbilt University. Is Anybody Out There? While eating lunch with some colleagues in 1950, Enrico Fermi made an innocent yet profound comment about life in the universe. As a well-known physicist, Fermi knew that the universe was old enough to possibly have other life present, especially within the Milky Way.

The stellar classification classifies stars based on their spectral characteristics. When passing through a prism, light from a star will be split into a spectrum displaying rainbow of colors interspersed with absorption lines. The strength of each line indicates the abundance of a specific ion. The abundance of different ions varies with the temperature of the photosphere. The classification of a star is giving an estimated value of the temperature of photosphere.
