Stargazing at Earth Hour

Join us in Bath on 28th March for a magical evening under the stars as we mark Earth Hour together. As lights switch off around the world, the night sky comes alive. This is an invitation to slow down, look up, and experience the beauty of the cosmos while reflecting on why protecting dark skies and reducing light pollution matters for people, wildlife, and the planet.

Transition Bath are organising this event in collaboration with Bath Astronomers, whose members will guide us through the night sky and help you use telescopes to see far beyond what the naked eye can spot. No experience needed, just curiosity and a sense of wonder.

On the night, an 81.7% waxing Moon will shine high above us. Astronomical twilight begins at 19:49, leading into Earth Hour from 20:30–21:30. If conditions are clear, we expect stunning views of the Moon, Jupiter and its four Galilean moons, and possibly Uranus. Venus will glow earlier in the evening after sunset, and we may also spot passing satellites amongst all the constellations.

We’ll meet at 20:00 just outside Victoria Park (exact location shared after booking), then walk together into the park at 20:15. Earth Hour begins at 20:30, followed by an hour of stargazing, guided telescope viewing, and gentle reflection. You’re welcome to share with others in our discussion points or simply enjoy the quiet awe of the night. If you have one, please bring a folding chair, especially if standing for long periods is difficult.

What is Earth Hour?

Earth Hour is organised annually by the World Wildlife Fund (WWF) and encourages people worldwide to switch off non-essential electric lights for one hour, typically from 8:30 to 9:30 p.m. local time on the last Saturday of March as a symbolic gesture of environmental responsibility and climate action.

To mark Earth Hour, we encourage you to:

• Switch off your home lights during Earth Hour
• Encourage local businesses to do the same

We’ll be sharing simple resources and ideas in the lead-up to the event and we’ll be taking part ourselves.

Important note about weather

Stargazing depends on clear skies. When you sign up, we’ll ask for your email address so we can confirm on the day whether conditions are suitable and the event is going ahead.
