Explore the universe in 3D with the Universe Applet
or get some more files and more commands
with the Large Structures Applet which may
also adopt a resizeable floating frame.
If the applet does not show up just above this text, it's probably because your
favorite browser (Firefox, IE...) no longer supports java applets.
For some time still you might try an older version.
If you have installed
you may also use
AppletViewer with the URL of this page.
Oracle has planned the definitive end of Java Applets, inclusive AppletViewer, in Java 9.
Hold the 3D universe in your hand
This applet shows a true 3D map (atlas or model) of stars and other objects in the Milky Way and thousands of
other galaxies near or far away. You get the 3D effect when you turn the universe around as a ball by
dragging it with the mouse. "True" means that positions of stars and galaxies are correct (but sizes are
Changing to one or several other files, turn the universe around and do some zooming is fine.
But there are many other possibilities. To get explanations and use them all take time to visit the
Large Structures Applet.
My applets have benefited from data compilations made by others. I have adapted files as they appear on
several sites, especially
NASA/IPAC Extragalactic Database (NED) which is operated by
the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National
Aeronautics and Space Administration.
VizieR at The Strasbourg astronomical Data Center
(CDS) with of course lots of files but not so many with distances to the objects
An Atlas of The Universe of Richard Powell. His maps
inspired me the idea of these applets
Galaxy Map of Kevin Jardine, a very complete documentation on
Open Exoplanet Catalogue of Hanno Rein.
JPL Solar System Dynamics for data on the solar system planets and their orbits.
The Large Structures Applet offers 3D asteroid and comet orbits as well.
Heavens Above by Chris Peat for data on Pioneer
10 and 11, Voyager 1 and 2 and New Horizons far away spacecrafts
You should use the button "Data" down left in the applet to see more details concerning the sources of
each individual file.
