🌑 Shadows Across the Solar System: How Eclipses Unfold Beyond Earth
From section: 🌞 Solar eclipses across the Solar SystemFrom the Martian surface, the Sun appears smaller than it does from Earth, yet still larger than either moon. The result is a fleeting, almost delicate interruption of sunlight. Robotic missions have captured these events, showing the moons as dark shapes gliding across the solar disk.
