The Great Equatorial Telescope at the Royal Observatory Museum in Greenwich…

The Royal Observatory Museum in Greenwich is a pretty cool place all about our connection to the stars. One of the highlights is the Great Equatorial Telescope, which is super famous. It was built back in the late 1800s and used by astronomers for over 70 years to explore the night sky. The name comes from how it's mounted, which lets it follow stars as they move, even as the Earth spins. It's inside a round building that makes it easy to point the telescope anywhere in the sky. People used the Great Equatorial Telescope for all sorts of research, like checking out different kinds of stars and galaxies and even snapping pics of the moon. Today, visitors to the museum love checking out the telescope but also standing on the Prime Meridian Line, which splits the planet into the eastern and western hemispheres – The Royal Observatory Museum, Greenwich, UK
