Earth-Life Science Institute is pleased to announce that the 3rd ELSI International Symposium will be held on January 13 -15, 2015.

"Life in the Universe"

Place: Kuramae Hall, Ookayama campus, Tokyo Institute of Technology.
Kuramae Hall is located across the street from Ookayama Station. When you exit the station, you will see a sign for Excelsior Caffe straight ahead across the street. The venue entrance is across from the cafe, in the glass doors.)
Organizing Institute: Earth-Life Science Institute

Scientific Organizing Committee:

Piet Hut (chair)
Yuka Fujii (co-chair for Signs of Life)
Hidenori Genda (co-chair for Cradles of Life)

The main theme of ELSI's 3rd International Symposium is the fundamental question: "Is there life in the Universe, outside Earth?" We still don't know the answer, but there is a good chance that the answer will be found within our lifetime. Robotic exploration within the solar system, as well as observations of planets circling other stars, may soon give us more tentative hints, and possibly even convincing evidence, of extraterrestrial forms of life. During the 3-day symposium, we will address three questions, respectively: 1) which planets seem fit as potential cradles of life; 2) what can we say about the likely properties of more universal forms of life, different from the one specific example we know on Earth; and 3) how can we best try to find signs of life elsewhere.
