The night sky can be truly spectacular

For those who love stargazing, there's nothing better than seeing a bright new star or recognising a beautiful constellation. Luckily, with the advancement of technology, you don't need a sky map to confidently point to a shining point and name it. Many useful apps have been released for Android and iPhone smartphones that will help you feel like a real astronomer.

The best thing about them is that there are many high-quality and free apps that work in point-and-click mode. To name the star you are looking at, you just need to point your smartphone with the app running and read the name.

Such apps also allow you to enter the name of a star, comet or planet and find out exactly where to look for it in the night sky. Here again, you don't need to have any special knowledge, as you just need to turn your smartphone in the direction the cursor in the app points.

How to find a star or comet

If you want to find out where the Big Dipper is located, or you're wondering what that reddish dot above your head is, use Star Walk 2 or Sky View. Both apps are very easy to use, convenient, have an augmented reality feature and intuitive search.

If you want to find more celestial objects without paying too much, use Night Sky (available for iOS only). With this app, you can find most celestial objects for free. For Android, there's Stellarium, where you can find asteroids, comets, deep-sky objects, satellites, and more for free. Stellarium is also available for iOS, but only its paid version.

The best apps for stargazing

To determine which app is the best (or most convenient for you), you'll need to explore a few of them and read reviews from other users. Alternatively, you can download a few of the top-rated free apps and evaluate them yourself.

For those who don't want to figure it out on their own, Vito Technology has published the top 20 apps for stargazing
