Viewing the Night Sky with Linux, Part II: Visit the Planets With

,----[ Quote ]
| Part I of this series covered a simple Linux planetarium program, KStars.
| But there are some questions KStars isn't very good at answering, like the
| question that began Part I: "What the heck are those really bright 'stars' in
| the sunset sky?" For viewing closeups of planets, monitoring the motion of
| the planets, getting precise predictions of events like eclipses, and other
| such information, you'll do better with a more powerful tool: XEphem.
| XEphem is the oldest and arguably the best-known of the Linux planetarium
| programs. It's not included in most Linux distributions due to its license
| terms, but its source is available to download and the program is free for
| personal, educational or research use. You can buy it, too: $69.95 gets you a
| pre-compiled version of the program plus three CDs worth of extra data files
| that aren't in the free version. It's worth it if you're a sky junkie like I
| am.



Exploring Space with Celestia

,----[ Quote ]
| I've found Celestia to be a lot of fun and extremely educational. My two sons
| enjoy being able to visit the planets in our Solar System. As a parent, it's
| satisfying to navigate to a planet on the computer and hear one of my sons
| exclaim, “Ooh, that's Saturn!”



Fun with free software astronomy

| Being a devoted backseat observer to the evolution of the Universe in
| general and GNU/Linux software in specific, I thought it was time to
| show off what I consider to be the elite of desktop elegance.


Free/Open-source Astronomy Software

| Astronomy, considered as one of the oldest sciences, is the scientific study

| phenomena that originate outside the Earth's atmosphere (such as the cosmic
| background radiation). *

| Conclusion
| I haven't really discussed the details about what type of information
| Celestia shows you. Obviously, you can set it to label stars, orbits,
| planets, and other bodies; it will tell you the surface temperature and
| luminosity of any object, its distance from any other object, and what class
| planet or star something is. This is all really great information for
| astronomers, and I have no doubt that this software will serve as a useful
| tool for anyone in that profession or field of study. But Celestia is great
| even for those who are just interested in space and the Universe. Celestia
| lets travel millions of light years without ever leaving home * * * *
