The Hubble Tuning Fork and Citizen Science

In this podcast extra episode we talk to Karen Masters, Associate
Professor of Physics and Astronomy at Haverford College,
Pennsylvania about The Hubble Tuning Fork and Galaxy
classification. But it’s not only about that canonised galaxy
classification system; it’s also about how citizen science,
astronomy done by absolutely anybody from their homes, can and do
change the accepted wisdom and advance science.
