Sky View Cafe

Sky View Café is a Java applet that lets you see many types of astronomical information, in both graphical and numerical form.

You can see which stars and planets will be out tonight in the sky above your home town, see how the next solar or lunar eclipse will look from Los Angeles, or find out when the Moon rose over Sydney on your birthday ten years ago.
Sky View Café includes star charts, a 3-D orrery, displays of the moons of Jupiter and Saturn, an astronomical event calendar, an ephemeris generator, and many other features.
