There is nothing like staring at the magnificence of the stars to make you feel tiny. But have you ever wanted to know more about those glittery floating dots? Astrology is the oldest natural science, and its observations have dated back since the beginning of recorded history. With a combination of modern-technology and past-knowledge, we now know more than ever about this source of fascination - and that is displayed clearly and intricately within this app.

Scan the skies by swiping with your finger, and the app will use its real-time motion tracking to display sensational images of constellations. Upgrade the app and be able to snap a photo of the heavens at night, and the sky map will give you detailed information on what you are gazing at. You can change a number of functions in the settings menu to alter how your screen displays the star readings, such as nigh mode which gives the screen a red glare.

▲ Swipe the screen to explore the atmosphere and view titled star constellations!

▲ View comprehensive information on the planets and their behavior.

▲ Observe the invisible structure of space with up to six filters - includes a red night vision mode!

Learn more about the stars, constellations, satellites, planets, and deep sky objects. Take a peek into the future, and view accurate data of the moons' expected path. Or take a trip back by changing the time and date, and observe past patterns and events at a magnitude difficult for the human mind to speculate. Navigate with ease using the compass as your guide, and browse into the unknown.

Whether you are keen to relieve your curiosity, or are planning some star gazing activities on an upcoming rural trip, download this app to fuel knowledge and encourage conversation.

Stargazers who use apps for meteor showers tend to end up relying on complex information to track theses astrological wonders. That is not such a good thing when you are trying to show the stats of a meteor shower to people who don’t know much about astronomy to begin with.

Fortunately, this simple meteor shower app is ideal for teaching the basics to beginner stargazers. Just scroll down to see the information on all the on-going meteor showers of the month. You can see the start, peak, and ending dates of all events, as well as what the moon phase will be on those nights!

▲ Get the list of all ongoing meteor showers for the month. Scroll down for more.

▲ Each meteor shower comes with a general image of its formation as well what phase the moon will be on its peak date.

▲There is also a weather forecast that you can consult so you can see if the sky’s clear enough to view.

There is also a graph that presents additional information about these meteor showers such as their number of stars. And much like the calendar, the information is simpler to digest for those studying these celestial events for the first time. That is why an app like this is ideal for stargazing camps with kids. The same goes for dates! Sharing a nice bit of trivia or two is always a good way to make something more meaningful. Meteor showers are no exception!

When it comes to natural lighting, nothing beats knowing when the sun will really rise and for how long. The same goes for the moon (and all its phases). That is why this lunar and solar calendar app is a better than any regular weather tool.

It goes especially for those who like the sight of these celestial bodies rising just above the skyline. Its accurate estimates of sunrise and sunset is perfect for timing that wonderful rooftop picture of the dawn. A quick glance is all it takes!

▲Know the lunar and solar forecasts for your city!

▲View additional details such as the altitude and the effects of the solstices!

Other useful information include the altitude as well as the length of day. It is perfect, not just for morning and dusk but knowing just how long you have to take those sunlit walks in the park or afternoon strolls.

A similar idea applies to the phases of the moon. Know what day has just that right crescent shape for a good picture. Where it is enough to see the clouds for the weather, a solar-lunar calendar is a better schedule for seeing that perfectly lit skyline!
