This guide will take you by the hand and guide you on your memorable journey through the universe around us.
From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars.
They called these objects planets, meaning wanderers, and named them after Roman deities - Jupiter, king of the gods; Mars, the god of war; Mercury, messenger of the gods; Venus, the god of love and beauty, and Saturn, father of Jupiter and god of agriculture.
The stargazers also observed comets with sparkling tails, and meteors or shooting stars apparently falling from the sky.
Since the invention of the telescope, three more planets have been discovered in our solar system. The science of astronomy is ever expanding.
This guide begins with a basic understanding of light and color. In the first three chapters you will learn the important role these forces play in astronomy and an understanding of the universe. Exciting experiments will help you in your learning.
Next we will examine the instruments used in astronomy and you will learn how to build a simple spectroscope from low cost materials.
Then it's on to our sun, moon and planets, where you will learn there distance from us and amazing facts about each of these bodies, and then beyond to study the meteoroids, asteroids and comets and ending up at the stars and constellations with star maps for observing the night sky.
This is the complete manual for beginning this exciting new hobby.

Star Chart does not require internet access for normal usage. Internet access is only required initially to verify the license and subsequently when accessing the support page and external links.
Augmented reality (AR) view: See the positions of planets or comets live on a camera image and search your selected object with your phone!
Since version 3.0 Planetdroid comes with a visibility diagram. You see the elevation above the horizon of your selected body (white line) of the current nicht and the elevation of the sun (dark yellow line), as well as the twilight times. The horizontal black line ist the horizon, the vertical red line your selected time.
Since version 3.3 it is possible to save locations offline. The file containing the locations is sdcard/.com.strickling/location.txt. It can be edited with any test editor. To start the editor, simply click menu in the location selection form.
Download elements for asteroids and comets from the internet.
Supports GPS localization.

The Night Sky - Simply Magical
The Night Sky is a magical new app that enables you to identify the stars, planets, galaxies, constellations and even satellites you can see above. Just stand anywhere and hold your Android Phone or Tablet up to the sky and The Night Sky will display the names of the stars, planets and other objects you are able to see, just like magic!
Even if your view is obscured by clouds or daylight, The Night Sky app will know which stars, planets, galaxies, constellations and satellites are hiding from your view! You have to use this app to realize just how amazing it is!
The Night Sky does this by using your location data provided by the GPS and compass built in to your device. It then cross references your location data with its inbuilt map of the sky and overlays the stars, planets, galaxies, constellations and satellites names on your screen. It really is magical and will amaze you, and anyone you show it to!
So next time you're gazing up in to The Night Sky and wonder the name of a star, planet, galaxy, constellation or even a satellite, just get out your Android Phone or Tablet and let The Night Sky app amaze your gaze!

You simply specify which object you are looking at, which telescope and eyepiece you are using, and a simple tap on a button brings you to a prefilled form to log your observation.
You can enter all your astronomical gear, even filters and barlow lenses.
To make sure you don't ruin your night vision, StarLog© Free features a night vision mode that turns the whole interface red, including the keyboard and all pop-up windows! You can even turn the brightness of the app down to a comfortable level.
You can full-text search through all your observations and sort them in various ways. StarLog© Free can export 5 of your observations in the OpenAstronomyLog format (OAL 2.0), for maximum compatibility with your other astronomical software. Support for exporting 5 observations to DeepSkyLog.be is built into StarLog© Free by default. Deepskylog is very popular in Europe. To make it easier to discuss your observations with others, StarLog allows you to make a screenshot of the observation, so that you can post it on forums or include it in e-mails.
To make your transition to StarLog© Free as painless as possible, you can import 5 observations and instruments from apps like 'Stargazing Log' and 'FOViewer (full or trial)'.
Limitations compared to the full version of StarLog©:
- No search option for objects.
- No restore option for backups.
- Only 5 observations can be exported to either CSV or OAL format.
- Only 5 observations can be imported from apps like 'Stargazing Log' and 'FOViewer (full or trial)'.
- Only 10 objects can be imported per observation list.
- No text-to-speech option.
- No voice recording functionality.
- Ad in the logging screen and details screen.
- No integration with SkEye for Go To/Push To functionality.
You can try/test the app in EVERY BROWSER by going here:

The object of the game is simple - simply answer as many questions as you can to gain points!
For example, the answer to the question '7 D in a W' would be '7 days in a week'. To answer this, type '7 days in a week' or 'days in a week' using the on-screen keyboard. (Hint : the game will accept spelling mistakes if you're close enough)
Each question offers 3 points. For every wrong answer, you'll lose a point. If you get stuck, use a 'clue', but you will also lose a point. Answering correctly will add these points to your total score. Your top score will be recorded along the way and new levels will be opened with the more questions you answer correctly!
