100 Hours of Astronomy is a yearly global celebration organised by the Office for Astronomy Outreach (OAO) that invites people of all ages and backgrounds to come together and connect with the night sky — and with the science that helps us understand it.
From vibrant cities to the most remote corners of the world, this event brings astronomy closer to communities everywhere. Through public stargazing, workshops, talks, and hands-on educational activities, 100 Hours of Astronomy sparks curiosity, encourages shared exploration of the cosmos, and invites us all to reflect on our place in the Universe.
This year, the main hub will be the Akashi Municipal Planetarium in Japan, an historic site located exactly on the 135° East meridian, where Japan Standard Time is measured. It is a fitting place to mark this global moment under the stars!
In addition to the main hub, we have Community Nodes around the world. These are local contact points where you can get support, ask questions, and join ongoing activities near you.
An amateur backyard observatory inside a SkyShed POD (the AstropotaPOD) will be streaming live views of the POD, mount, 102mm refractor, what the scope is looking at, and live-stacking, as well as views from a Seestar S50 for as long as the weather holds out! The Astropotamus and friends may join from time to time to discuss gear, techniques, and what we're seeing. Intended for people without a strong background in astronomy or astrophotography. English is the language.
October 2-5, 2025 is when the 100 hours will be. The AstropotaPODapalooza will be online as much as possible during that timeframe, based on weather, but the AstropotaPalooza is scheduled for October 4 into October 5.
Stay tuned to this web site and at the 100 Hours of Astronomy site for more information!
Until next time, clear skies, and I'll see you in the dark!
