Department of Astronomy Center for Radiophysics & Space Research

Friends of Astronomy

In 1992 the Department officially inaugurated a group called "Friends of Astronomy" composed mostly of Cornell alumni and friends. This has been a very happy experience with significant interaction between the Department and our Friends in the wider world.

Anyone with an interest in all things astronomical here at Cornell is welcome to join the Friends of Astronomy group. You can even join our Facebook page!

Take a Cornell astrophysics class from home: Explore relativity and astrophysics with David Chernoff:

Ever wondered about relativity? Pondered a black hole? Here’s your chance to take an Ivy League astrophysics course from the comfort of your own home, with Cornell University’s first-ever MOOC (massive online open course). The course is free and registration is currently open.

Course:     "Relativity and Astrophysics"
Who:     David Chernoff, Cornell professor of astronomy
Date:     Classes begin Monday, Feb. 3, 2014
