Scientific Program

Introductory talks will start the sessions dedicated to each of the above mentioned topics, followed by presentations of current state-of-the-art research. Towards the end of each session we plan to have general discussions to identify consensus on some questions and to find possible problems to solve by connecting the various fields.

 

Six sessions are planned:

 

1. Monday afternoon and Tuesday morning: The first steps toward chemical complexity: from pre-stellar cores to protoplanetary disks (observations, theories and experiments will be presented in this session, with the aim of linking the various steps in the process of star and planet formation and unveil the chemical evolution).

 

2. Tuesday afternoon until Wednesday morning: The Solar System (recent results on comets, meteorites, asteroids and moons will be summarized here, with particular emphasis on organic matter. Links to the previous phases described in the previous session will also be highlighted).

 

3. Wednesday afternoon: Exoplanets and habitability (the characteristics of other stellar systems will be presented, with particular attention paid to exoplanet atmospheres and their chemical composition. Description of theories and predictions for future observations of Terrestrial-like planet atmospheres will also be included in the program).

 

4. Thursday morning: Primitive Earth and conditions to host life (for life to develop, chemical raw materials are necessary. Because data regarding the atmospheric, oceanic, or geological conditions on the pre-biological Earth are scarce, it is difficult to determine conclusively whether terrestrially synthesized organic material or extraterrestrial molecules were more significant for life’s origin. However, life Earth emerged rapidly. Recent findings discovered 3.7 billion year old stromatolite fossils in the world’s oldest sedimentary rocks in the Isua Greenstone Belt along the edge of Greenland’s icecap. Since then life on Earth has adapted to nearly every explored environment. The progress and the revolutionary quality and quantity of data on “extreme life” on Earth have transformed our view of habitability beyond Earth. Past conditions of Mars may have allowed life to develop. In particular, the earliest liquid-water rich era would present the most habitable conditions. Investigations of the oldest rocks on Earth, the impact history of asteroids and comets, the search for early biosignatures, and space missions to investigating habitability in our Solar System provide major opportunities to understand the prebiotic reservoirs and the conditions for the emergence of life on Earth (and Mars)).

 

5. Thursday afternoon: The assembly of prebiotic molecules and 6. Friday morning: Steps towards evolution (solving the origin of life means to bridge from early geology to nonequilibrium processes and early molecules that can give raise to Darwinian evolution at the nanoscale. Experimental approaches to this large puzzle will be presented and new links between disciplines and and theoretical approaches discussed. The aim is to come up with new, connecting experiments).

******************************************

 

 

Long coffee breaks (45 min x 2), lunches (1.5 hours) and discussion sessions (45 min x 2) each day will give us the opportunity to discuss and make sure that the various communities interact and understand each other.

 

PhD students and Postdoctoral Fellows will be encouraged to attend the meeting and give contributed talks or present posters. They will have the opportunity to interact with world-class experts in the fields of star and planet formation, astrochemistry, Solar System, exoplanets and origins of life. The highly interdisciplinary environment will be particularly beneficial for young scientists, who may find new directions in their research by connecting different fields.

 

Aims of the WE-Heraeus-Seminar

The aims of this conference are:

 

1. Gather together different communities, all interested in the origins of life, and provide a highly interactive environment to allow communication and foster discussions as well as interdisciplinary collaborations.

 

2. Learn from each other where do we stand and what are the remaining open questions. Collect a global view of the evolution of the chemical complexity from the first steps in space until the chemistry of life on Earth.

 

3. Encourage students and young researchers to see the 'big picture' and motivate new ideas for future missions and experiments.
