Astronomers have recently discovered two galaxies that might present a challenge to a broadly accepted theory of how galaxies form.

In this edition of Looking Skyward, CAI's John Basile discusses this discovery with Dr. Regina Jorgenson of the Maria Mitchell Observatory on Nantucket.

This is an extended version of Looking Skyward. It includes material not in the piece that aired on CAI.

Falmouth to Falmouth: Connecting Cornwall to Cape Cod

F2Fsection.png (1640x924, AR: 1.774891774891775)A Unique Radio CollaborationEarly in 2022 we embarked on an experiment to connect CAI, located in Falmouth, Massachusetts, with SourceFM, a radio station in Falmouth, UK. But the mission was even broader: to connect listeners on Cape Cod, USA, with listeners in Cornwall, England.On this page you'll find the hour-long episodes of this experimental collaboration. Each is focused on the voices of individual people speaking to each other directly, across the Atlantic Ocean, sharing their experiences around subjects immediately important to them.We hear them talk about surviving the pandemic, addressing climate change, housing struggles, community policing, and much more. We hope you'll explore the stories here and enjoy the voices and what they share.And we’re looking for suggestions for future episodes! Want to join the conversation?
