Security problems running Java apps? In its Update 51 Java 7 raised the security restrictions and does not accept university "self-issued" security certificates. We are working at resolving this problem, but a temporary fix is to add the http://carma.astro.umd.edu site to the Java Exception site list in your Java.
To do so bring up the Java Control Panel (found under System Preferences in a Mac, or here in Windows, or by typing 'java -viewer' in Linux and closing the 'Java Cache Viewer' window). Click on the 'Security' tab. Using the 'Edit Site List...' button add 'http://carma.astro.umd.edu' to the list of sites. The system will complain that it is not a 'secure' https connection, but confirm it anyway. That should fix any problems with security exceptions.

Why is the sky dark at night? Olbers’ Paradox


Light at different wavelengths. Explore the appearance of galaxies


Understanding astronomical redshifts. Velocity and the Doppler effect


Understanding cosmological redshifts. Doppler effect from changes in path


Light responds to gravity. A gravitational lensing explorer


The expansion of the universe. Play with Hubble’s law


The fate of the universe. Play with the cosmological parameters and see their effects


Gravity, orbits, and Black Holes. How do astronomers measure mass?
