Astronomy is really freaking cool. If you agree, you’re going to love these apps.

From augmented reality to exploring the universe from home, these Android apps can take you through the cosmos and are both educational and fun. You can already find some amazing astronomy content out on the Web Get To Know The Universe With These Amazing Astronomy Websites Get To Know The Universe With These Amazing Astronomy Websites Very few of us are likely to ever make it into outer space, unless the various space tourism ventures become mainstream successes. Even then the price of being flown into space will be so high... Read More , but today let’s take a look at some of the best Android apps for this.

Star Walk 2

While online space telescopes Amateur Astronomy Fun: What It’s Like To Look Into Space With These Free Online Space Telescopes Amateur Astronomy Fun: What It’s Like To Look Into Space With These Free Online Space Telescopes Buying a really good telescope remains a distant possibility. Magnification is a lesser problem; an always polluted sky is the greater one. But thanks to the handshake of the modern web with cutting edge imaging... Read More are awesome, augmented reality apps step it up another notch to make you the telescope. With Star Walk, you simply hold your device up towards the stars and it uses your device’s internal sensors to determine where you’re pointing it. It then shows you a layout of what stars and planets are in front of you, and you can tap on them to learn more.

This is by far the best app on this list, and it’s incredibly easy to use. Just point your phone at the sky and learn about the stars and planets up there. You can even see where the ISS is at any given time. Of course, your phone will need a digital compass for all of this.

Star Walk 2 is the successor to Star Walk, which used to be one of our favorite astronomy apps. The newer version has a much cleaner interface, smoother performance, and it has a free version and a paid version.

Overall, this app is the one-stop shop for staring up at the sky and getting all the information you could want.

Star Chart

As a solid free alternative to Star Walk 2, users would still be happy with Star Chart. This one can be used in portrait or landscape and has the same general idea: hold your phone up to the sky and it will orient itself using your location and compass to show you what’s in the sky.

Star-Chart-Options-Display-1

While the app is free, in-app purchases can add up quick as shown in the menu above.  You can also adjust your settings in this menu and find particular night sky objects that you’re looking for.

Star-Chart-Mars-1

While searching around the sky, tapping on any object will give you a little pop-up as shown above. You can then choose to zoom in on that object and admire it in all its 3D visual glory.

A small microphone also hangs around the bottom of the screen for voice controls, but what voice commands do what is a little unclear. “Show me Great Bear” will take you into the Sky view to see the Great Bear constellation, as shown above to the left, but “Go to Mars” will take you into 3D explore mode and zoom up on the red planet.

Star-Chart-3

Star Chart also has a night mode for dark blacks and red to stay easy on the eyes. However, the black bar that stays along the top with the blue icon draws the user a bit out of the experience as compared to other apps which go full screen and feel more immersive.

Still, as a free app, Star Chart is a great deal — even if its interface is a bit more dated.

Sky Map

This open-source Sky Map isn’t the most robust option here, but it’s simple to use and completely free. For the occasional identifying of constellations, it works fabulously.

Sky-Map-Buttons

The interface shown above is really all that you get. You can toggle which objects are shown — planets, constellations, stars, etc. — and switch between automatic and manual controls. Automatic controls allow you to use the compass in your phone to determine what you’re seeing, while the manual mode just lets you explore the sky by swiping around.

Sky-Map-1

Without all the bells and whistles of the other apps, and being a much smaller download, this could be a better app for devices with more limited hardware, but be aware that you’ll need an internal compass and GPS for the automatic viewing to work.

Solar Walk

Made by the same people as Star Walk, Solar Walk is like a 3D model of our solar system with incredible graphics and information on all of the planets. This one is less for staring up at the stars at night and more for sitting around learning about the solar system, but it deserves a mention in any discussion of astronomy apps.

Selecting a specific planet will allow you to get in-depth information on it, even down to the internal structure. This is such an incredible education tool that it really should be loaded on tablets used in schools.

Solar-Walk-Saturn

In the settings, there’s an interesting option for a 3D mode. Have a pair of old 3D glasses lying around? Then you can even have a 3D solar system experience! This app keeps much of the same interface as Star Walk, but with a clear focus on the planets of the solar system rather than the stars of the universe.

Solar-Walk-Options

The download, a hefty 300MB in size, is free, but it’s just a trial version. Gaining access to any planets except for Saturn will cost you $2.90. Still, there’s not a more fun way to explore the solar system out there.

Stellarium Mobile

As the mobile version of a popular desktop app, Stellarium Mobile is often a fan favorite. It has a massive catalogue, a relatively intuitive if someone dated interface, and great graphics.

You won’t be disappointed with Stellarium, though you will have to shell out $2.49 to buy it. Still, it has no ads or in-app purchases, so you’re getting a very clean experience here. For a simple, no-frills astronomy app, try out Stellarium Mobile.

    End of Movement 1 of Rachmaninov No 2 in C Minor. But you do not e n j o y the sky! It is not a consumer product. You gaze at it and feel awe.

    Good apps, but the American Almanac 2 has way more data, including weather and calendars, and it's presented in a really unique format.

    Which of these Apps will show the International Space Station?
    You can see when it'll be visible in your area from the NASA 'Spot the Station' web page and I've seen it cross the sky three times recently.

    I told a friend that the ISS was going to be visible later that evening. He pointed his iPhone about 30ยบ down, towards the floor, and said that it's down there now.

    Major problem that you should have Highlighted Justin. This app does not work if your phone or tablet is not equipped with a digital Compass. (some phones aren't).

    Luckily, I tried it out within the two hour Google Play period and got a refund, but you seriously need to mention this.

    Thanks for this, Justin - a brilliant article.

    I'm definitely going to get StarWalk; that's essentially what I've been looking for in an astronomy app!
