Cradle of Life

The Cradle of Life (CoL) working group focuses on four main science themes:

1) how Earth-like planets form;

2) how life originated on Earth;

3) what exoplanets look like; and

4) the search for extraterrestrial intelligence (SETI).

The SKA will study how sub-micron interstellar dust particles stick together and grow in proto-planetary disks as a key step in rocky planet formation; it will search for pre-biotic molecules such as amino acids and their precursors in the medium between stars; it will study the magnetosphere of exoplanets and their interaction with stellar winds; and it will perform deep searches for artificial signals from exoplanets in our neighbourhood.
