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.

Science activities and meetings:

  1. TNOs (Trans-Neptunian Objects) meeting organised by Thomas Muller and Pablo held in Granada (Spain) from the 25th to 27th of April to explore the TNO science that could be done in the future with the SKA.
  2. SKA Dutch community meeting held in the 24th of May at ASTRON in Dwingeloo.
  3. SKA CoL poster contribution at the “Astrochemistry: Past, Present & Future” meeting held at Caltech from the 10th to the 13th of July.
  4. SETI session at the COSPAR 42nd Assembly held in Pasadena from the 14th to the 22nd of July.
