The Harwell Space Cluster provides a gateway to the UK Space Sector, aiding your journey of discovery and growth. RAL Space is the space hub for UK Research and Innovation and the Harwell Cluster, providing cutting edge facilities for scientific instrument development, satellite and equipment testing, scientific research and performing world-leading data processing and analysis.

With more than 50 years of expertise, RAL Space has contributed to over 210 space instruments, including the Gaia Spacecraft, surveying a billion stars in our galaxy since 2013. Throughout history, humanity has always marvelled at the stars – and with new technology like the James Webb Space Telescope we’re able to look deeper and further into the Universe than ever before.

Ground Observatories

ALMA Observatory of multiple Radio Telescopes
ALMA – Ground Observatories

Scientists and researchers across the world observe the cosmos using powerful telescopes. These ground-based observatories are often found at high altitudes, in remote locations, or just generally far away from other people, so they can get the best images and readings with the least interference from local sources.

UK Observatories

Many of the large-scale observatories across the UK host regular events for members of the public to attend, find out more from their websites linked below.

Earth and the Moon

Earth and the Moon

Our home planet Earth has just a single moon, often called ‘Luna’ or simply ‘The Moon’ – which is the brightest object in the night sky. The Moon makes one rotation around Earth every 27 days, but it is tidally locked which means the same side always faces us. Although this does not mean the moon has a dark side – only a side that we never get to see from Earth. Start your journey of learning here, with some resources and links around the Earth and Moon.

Stars and Constellations

Signs of the Zodiac – Stars and Constellations

When you look up at the night sky and see hundreds of twinkling lights, do you wonder how far they are away? Why they are different colours and sizes? Have they been there forever or will they one day disappear? For thousands of years, our ancestors observed the movements of stars and even named certain groupings that resembled a pattern or picture based on legendary figures – what we now call Constellations. We have now surveyed almost a hundred million stars just within our home galaxy: The Milky Way. From the Largest Blue Supergiants to the smallest Red Dwarf stars, there’s a whole world of objects to explore, right from our planetary doorstep!

The Solar System

Planets of the Solar System

The Earth belongs to a collection of planets, moons, comets and asteroids, all orbiting around a typical star we call The Sun. This collection of bodies forms what we call the Solar System, it contains 8 planets including Earth, 5 dwarf planets and many hundreds of other smaller objects. For the last 70 years we’ve been sending all kinds of spacecraft out into our local region to answer some important questions like; How do stars and planets form? What do the other planets and moons look like? We’ve even tried changing the path of an asteroid by colliding a spacecraft into it (spoiler: it worked!) There’s so much still to discover about our cosmic backyard, and we hope you will start your journey of exploration here.
