C2 – Commission C2 Communicating Astronomy with the Public


It is the responsibility of every practising astronomer to play some role in explaining the interest and value of science to our real employers, the taxpayers of the world. IAU Commission C2 has the following objectives:

  • To encourage and enable a much larger fraction of the astronomical community to take an active role in explaining what we do (and why) to our fellow citizens.
  • To act as an international, impartial coordinating entity that furthers the recognition of outreach and public communication on all levels in astronomy.
  • To encourage international collaborations on outreach and public communication.
  • To endorse standards, best practices and requirements for public communication.
