Celestia is a free real-time space simulation that lets you experience our
universe in three dimensions. Unlike most planetarium software, Celestia
doesn't confine you to the surface of the Earth. You can travel throughout
the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All travel in Celestia is seamless; the exponential zoom feature lets you
explore space across a huge range of scales, from galaxy clusters down to
spacecraft only a few meters across. A "point-and-goto" interface makes it
simple to navigate through the universe to the object you want to visit.
Celestia is expandable. It comes with large catalog of stars, galaxies,
planets, moons, asteroids, comets, and spacecraft. If that's not enough,
you can download dozens of easy to install add-ons with more objects.
gkrellmoon is a moon clock plugin for Gkrellm2. This plugin is based
upon the glunarclock and wmMoonClock applications.
The port is based on the original gkrellmoon port for Grellm1 by Patrick Li.
fowsr is an application that reads from wireless weather stations
* WH1080 / WH1081 / WH1090 / WH1091 / WH2080 / WH2081
* Watson W-8681
* Scientific Sales Pro Touch Screen Weather Station
* TOPCOM NATIONAL GEOGRAPHIC 265NE
* PCE-FWS 20

and other similar USB devices from Fine Offset Electronics Co., LTD.
compatible with the EasyWeather application .
The result is a weather history log file that can be uploaded to a central
server for further processing. Example script files for uploads is included.
So far the following formats are supported:
* Weather Underground
* pywws
* XML
fowsr performs a complete read out of the weather station memory using its
USB port, and stores the result in a cache file to speed up later read-outs.
Rain data is then calculated per hour, day, week and month if data for these
periods exist. No further data processing is performed. This makes fowsr
very small and well suited for running in embedded devices at remote
locations.
libnova is a general purpose, double precision, astronomical calculation
library. The intended audience of libnova is C / C++ programmers, astronomers
and anyone else interested in calculating positions of astronomical objects.
Marble is a Virtual Globe and World Atlas that you can use to learn
more about Earth: You can pan and zoom around and you can look up
places and roads.
Mymoon is an ncurses-based tool that presents for the given latitude
and longitude a continually updated display of:
- Percentage of Moon's surface illumination
- Distance between Moon and Earth
- Moon set and Moon rise
- Moon age
Astro::Flux provides a class for handling astronomical flux quantities. This
class does not currently support conversions from one flux type to another (say,
from magnitudes to Janskies) but may in the future.
Osmium is a C++ framework for working with OSM data files. Osmium
can read OSM data in XML or binary format (PBF) and can call different
handlers for each OSM object.
Astropy is a package intended to contain core functionality and some common
tools needed for performing astronomy and astrophysics research with Python. It
also provides an index for other astronomy packages and tools for managing
them.
Pymetar is a python module and command line tool designed to fetch Metar
reports from the NOAA (http://www.noaa.gov) and allow access to the
included weather information.
