Other projects I developed.
JPARSEC is very powerful on sky charting, and as a desmostration I have recently created an sky atlas with a layout similar to the well known Sky Atlas 2000, by Wil Tirion. Main difference is that the atlas is created for equinox 2013, showing the trajectories of the external planets, the Sun, 2012 DA14, and comet ISON. It requires an update yearly, but I think it is more useful. Another difference is the deep sky textures (and Milky Way!) shown in the dark edition, and the radiants of the meteor showers. It is my first approach on a sky atlas, and obviously some details can still be improved, but the result is great. A description of the atlas is provided in my blog.
A web ephemerides server that produces accurate astronomical ephemerides of solar system bodies is now available. To have a good performance, the accuracy is intenctionally slightly below that of the JPL Horizons for dates far from year 2000 (in current dates accuracy is similar), but the quality of the charts and the interactivity and performance when simulating astronomical events if by far above any other web tool. In addition, probably you have never seen such a level of completeness and detailed data. Current version is available in Spanish and English.
Here are some interesting phenomena you can simulate interactively with this ephemerides server (using the applet described below):
A multiplatform (maybe biggest ever?) applet that simulates the sky and the planets as seen from a given place and with a given telescope and ocular. Java 1.6 is required to launch this program, and Spanish and English versions are included. Download it here and enjoy it!
You can also try it online in English or in Spanish. In the first execution the applet requires to download more than 30 MB of data. Note this applet, as any other, will only work with old browsers (or maybe the current version of Firefox) and/or if you download and execute it from your hard disk.
”This is extraordinary. I have not seen anything even close to this as a Java routine anywhere else. Thank you very much for providing the applet. We will explore it and then have students give it a test drive too”, John Kielkopf, Professor of Physics and Astronomy, University of Louisville, USA.
The applet was updated for the last time on January 29, 2014.
Windows program to learn astronomy. It was made as my final degree project with Windows 95 graphic libraries (a long time ago!) and using Fortran 90. It was so nice that I decided to never use Fortran or those graphic libraries again anymore. The monster can still be executed in XP, but be sure to maximize the window and put it at the top left corner. Download it here (or here for the Spanish version) and enjoy!
Several applets that shows the Solar System, the sky, and artificial satellites. Also quite old. They can be downloaded here.
An applet to explore certain places based on photographs taken from every possible direction. Quite old, but funny. There are two virtual visits available:
