Pourquoi l'étoile du Berger est-elle surnommée ainsi? Facilement repérable dans le ciel du matin ou du soir, l’étoile du Berger désigne en réalité la planète Vénus, qui fait partie de notre système solaire.

A study shows Australian Bogong moths use the night sky for navigation during their 1,000-km migration, making them the first invertebrates documented to do so. Their brain activity suggests strong responses to specific star orientations.

A mesmerizing long-exposure photograph captures concentric star trails circling a majestic oak tree in Almaden de la Plata, Spain. The image, created from a series of 30-second exposures over nearly 2 hours, showcases the Earth's rotation with Polaris, the North Star, subtly visible near the center. The tree's silhouette is dramatically framed against the swirling star paths, creating a captivating visual of celestial movement and earthly beauty.

Drones can avoid GPS jammers by navigating with the stars An ancient mapping technique may offer a reliable backup tool for UAVs.

The celestial alignment feels auspicious for a journey. Arranging an outing to view the glimmering nebulae with Mia and Me. Any recommendations for suitable coordinates? #stargazing #auroradawn #celestialnavigation

You can't get this feeling anywhere else. Beautiful nautical art.

Before GPS, mariners navigated by the stars! ✨
Celestial navigation is still taught today, so even if technology fails, your ship’s officers can find the way using the sun, moon, planets, and stars. Pretty amazing right? 🌌 #CelestialNavigation #CruiseFacts #Waycruise
