Filled with stars, planets, and other celestial objects, space is a source of fascination to many. It’s a place that promises infinite discoveries. And you don’t even need to be in the classroom or behind a telescope to be making those discoveries anymore. All you need is an iPhone.

If you love learning about the skies above, check out these awesome space apps on your iPhone.

1. NASA

When it comes to space, the first organization you’ll probably think of is NASA. If you already follow NASA’s social media and use it as a source for iPhone wallpapers, why not download the NASA app as well?

Discover the latest news, images, and videos from NASA in this app. Or watch NASA TV and listen to podcasts. Another neat feature of the app is its augmented reality, showing interactive 3D models. Pick a model, point your device at an empty space, and you’ll get to see how Mars rovers and Atlas rockets look in your room.

Turn on notifications to get an Astronomy Picture of the Day. You’ll get updated about sighting opportunities and NASA events, too.

2. Sky Guide

Sky Guide one of many great apps to help you enjoy the night sky. View Sky Guide’s calendar to note down the dates of the meteor showers and when the best times to view them. Or use it to learn when the moon will be waning, when you might be able to spot Venus or Mars, and the best way to spot Mercury. For even more information, you can read featured articles and news written by astronomers and authors on the subject.

When setting your location, zoom in from orbit down to ground level and choose a location from Sky Guide’s map, like with Google Earth. Choose your location correctly to avoid unnecessary let-downs about potential sightings. For example, the app may state that there will be a lunar eclipse on a particular date, but inform you that due to your location you won’t be able to observe it.

Remember to set up notifications so that you won’t miss once-in-a-blue-moon events, like an eclipse or a meteor shower. Sky Guide offers observing tips too!

3. Satellite Tracker

In Satellite Tracker, find various traveling satellites by choosing from one of three views: Globe, Satellite, and Sky.

There’s a flyby timer so you can know when a particular satellite is expected to pass by. The app also provides predictions on whether the satellite will be visible.

Satellite Tracker has more than 19,000 satellites in its database. You can track famous satellites, such as Space X’s Starlink satellites, as well as communications, weather, and navigation satellites.
