Humanity has been gazing at the stars since the dawn of civilization, finding points of navigation and dreaming of what lay beyond. Previous generations could only learn about the specifics of the skies through star maps, books, and planetariums. Today, everyone is walking around with the ability to study the cosmos in their pockets thanks to astronomy apps.

Modern astronomy apps use all the technology packed in your mobile devices — a compass, GPS, gyroscope, time, and dates — to give stunningly accurate maps of the stars. Many don’t even require you to have a data signal to use, allowing you to see the majesty of the stars even while hiking in rural areas.

Night Sky (Free, premium upgrades)

In the world of astronomy apps, one name reigns supreme: Nightsky. This freemium app offers a jaw-dropping amount of features without ever asking for a dime, but if you’re willing to pay the options are seemingly endless. Free users get one of the largest collection of star maps on earth, featuring millions of stars. An augmented reality feature uses your camera to map the stars in the sky above exactly as you see it. Whether you want to see stylized constellations or traditional outlines, Nightsky has you covered. Users get access to powerful filters, from a light pollution indicator to x-rays to let you see beyond the standard visual spectrums. There are quizzes to test your knowledge and educational functions that teach you about the internal structures of planets throughout the solar system. Premium users also get the ability to map the closest Aurora to your location. You can even add the time you spend stargazing to your mindfulness minutes in your Apple Health app. The only downside of the app is how overwhelming its sheer number of options can be for new users. 

Skyview ($1.99)

Overwhelmed by Nightsky? Try Skyview. This simple point and view astronomy app make it easy to quickly identify galaxies, stars, constellations, and planets. You can even track satellites that might be above you at any moment, including the international space station. Scheduling features make sure you never miss a major celestial event that comes in handy for those one-in-a-lifetime planetary moments. Skyview has a wonderfully simple augmented reality feature that takes images from your camera and overlays constellations directly where they naturally occur in the sky. There’s even a time jump option, letting you see what the stars would look like at your location during different time periods. Skyview offers a ton of options for one low cost.

Like most other astronomy apps it also features augmented reality options and a pocket planetarium, but the educational features are truly the highlight of SkySafari. For young astronomers looking to learn more about the sky, SkySafari is worth signing up for.
