Gazing at the sky on a clear night is a unique experience, even more special when a meteor shower occurs or we see planets shining alongside the most well-known constellations. However, recognizing all those luminous points with the naked eye and differentiating stars, planets, comets, or satellites is difficult without prior knowledge of astronomy. In the past, it was necessary to consult manuals or star charts on a computer, but today technological advances offer Android applications capable of identifying and showing us the universe in real time , simply by pointing our phones at the sky.
In this comprehensive article, you'll find a carefully curated selection of the best apps for discovering constellations, stars, and planets on Android .
