Planetary Habitability Index Proposes A Less 'Earth-Centric'
View In Search Of Life
by Tammy Plotner

It's a given. It won't be long until human technology will
expand our repertoire of cataloged exoplanets to astronomical
levels. Of these, a huge number will be considered within the
"habitable zone". But, isn't a bit egotistical of mankind to
assume that life should be "as we know it"? Now
astrobiologists/scientists like Dirk Schulze-Makuch with the
Washington State University School of Earth and Environmental
Sciences and Abel Mendez from the University of Puerto Rico at
Aricebo are suggesting we take a less limited point of view.

"In the next few years, the number of catalogued exoplanets will
be counted in the thousands. This will vastly expand the number
of potentially habitable worlds and lead to a systematic
assessment of their astrobiological potential. Here, we suggest
a two-tiered classification scheme of exoplanet habitability."
says Schulze-Makuch (et al). "The first tier consists of an
Earth Similarity Index (ESI), which allows worlds to be screened
with regard to their similarity to Earth, the only known
inhabited planet at this time."

Right now, an international science team representing NASA,
SETI,the German Aerospace Center, and four universities are
ready to propose two major questions dealing with our quest for
life =96 both as we assume and and alternate. According to the WSU
news release:
