Every other Friday, the Astronomy Department at Columbia University sponsors public outreach giving members of the public access to astronomical information through timely lectures aimed at a public audience given by members of the department. After the lecture, if the weather is clear, the public can proceed to the roof of Pupin Hall and observe the sky from the telescopes of Rutherford Observatory. A slide show and discussion with an astronomer about various astronomical images happens if the weather is cloudy. 

Lecturer and title:

Sasha Hinkley, PhD candidate in Astronomy, "Imaging New Planets from Here on Earth".
