The 8 best Astronomy Apps to learn about the Universe

Observing the celestial vault with optical instruments or with the naked eye, also using the Apps to see the stars, may not always be possible.

This is mainly due to light pollution, which makes it almost impossible to sometimes enjoy the celestial spectacles. In addition, even the reduced view that we can have when looking at the balcony of the house, can negatively affect our observations.

We have therefore thought of a series of Astronomy Apps, to help us get to know the cosmos through our smartphone. Some of these use augmented reality, others offer us spectacular images of our universe, to understand and study it.

Here then are the 8 best Astronomy Apps to get to know the Universe!
