Space news (June 06, 2015) – The human search for life beyond Earth reaches for new horizons this week with the announcement NASA’s bringing together space scientists spanning a variety of scientific fields to form Nexus for Exoplanet System Science (NExSS).

Nexus for Exoplanet System Science (NExSS) brings together top research teams in Earth and planetary science and Helio and Astrophysics in an effort to determine the habitability of exoplanets discovered during the human journey to the beginning of space and time.

“This interdisciplinary endeavor connects top research teams and provides a synthesized approach in the search for planets with the greatest potential for signs of life,” says Jim Green, NASA’s Director of Planetary Science. “The hunt for exoplanets is not only a priority for astronomers, it’s of keen interest to planetary and climate scientists as well.”

Since the beginning of NASA’s Kepler Space Mission six years ago planet hunters have discovered 1852 exoplanets. Currently, there are another 4661 candidates detected by the Kepler Space Telescope, being examined closely for evidence to prove the existence of life beyond Earth. NExSS space scientists will develop techniques to confirm the habitability of these exoplanets by searching for ‘signs of life’.

Earth and planetary scientists, Heliophysicists and Astrophysicists use a “System Science” approach to better understand the ‘signs of life’ they need to look for on exoplanets discovered. They want to understand how life-on-Earth interacts with the atmosphere, geology, oceans and interior of the planet, and how this is affected by our sun. In an effort to develop better techniques to detect life on distant planets.

Dr. Paul Hertz, Director of the Astrophysics Division at NASA notes, “NExSS scientists will not only apply a systems science approach to existing exoplanet data, their work will provide a foundation for interpreting observations of exoplanets from future exoplanet missions such as TESS, JWST, and WFIRST.” The Transiting Exoplanet Survey Satellite (TESS) is working toward a 2017 launch, with the James Webb Space Telescope (JWST) scheduled for launch in 2018. The Wide-field Infrared Survey Telescope (WFIRST) is currently being studied by NASA for a launch in the 2020’s.

The search for life goes on

NExSS is led by Natalie Batalha of NASA’s Ames Research Center, Dawn Gelino of NASA’s Exoplanet Science Institute, and Anthony del Genio of NASA’s Goddard Institute for Space Studies. They’ll lead team members from ten universities and two research institutes as they search for exoplanets with signs of life.

Humans have searched for signs of life in the night sky for thousands of years and some claim to have met and interacted with extraterrestrial beings during this time.

Now, humans desire to meet and communicate with beings from another world, and NExSS is the next step towards finding the answer to the eternal question.

Are we alone in the universe?
