Java While most of the Java applets in Online Journey Through Astronomy were created using Java 1.0, a few are 1.1 level. All of the Java applets should be viewable with both Netscape and Internet Explorer for Windows, and with Internet Explorer for Macintosh. At present, however, Java 1.1 is not supported by Netscape on the Mac, and you will not be able to view these applets with that browser: the constellation viewer and the escape velocity, mass / weight, Kepler's laws, center of mass, time dilation, and space contraction calculators.




Monitor Requirements

Resolution

OJTA needs a monitor with at least 800 x 600 resolution. The image below is 800 pixels wide and 600 pixels tall. If your monitor has this resolution or greater, you should be able to see all of the image on your screen. (Drag the browser edges, if necessary, to expose all of the image.) If your monitor is capable, we highly recommend you set its resolution to at least 1024 x 768.


Color Depth

For optimal viewing of many graphic elements, you should have your monitor set to display millions of colors.







If your browser passes all these tests, you have the tools you need for
     Online Journey Through Astronomy.

We hope your explorations of our Universe will be informative and enjoyable!
