About the show
Making planetary science personal, engaging, and mind-blowing — through the universal experience of time.
Have you ever wondered what time means on another world?
On Earth, a day lasts 24 hours. But on Jupiter, it’s less than 10. On Venus, a single day stretches 243 Earth days.
Time Across the Solar System takes you on a cosmic journey where every planet keeps its own clock. Each episode turns scientific fact into cinematic storytelling — blending NASA data, imaginative narration, and stunning cosmic soundscapes.
