150 Years of Discovery

Nature, Science and Discovery

Founded in Northampton in 1876, Northamptonshire Natural History Society (NNHS) has been part of the county’s scientific and cultural life for 150 years.

Our interests span natural history, wildlife, geology, astronomy, botany, microscopy, photography, weather and climate, and local history, bringing an extraordinary variety of subjects together under one roof at the Humfrey Rooms in Northampton.

Whether it’s looking through a microscope, exploring Northamptonshire’s rocks and wildlife, studying the weather, photographing the natural world or turning a telescope towards the night sky, there are countless ways to get involved.

150 years of knowledge, exploration and discovery – with plenty still to come.

Our history is remarkable, but we’re much more interested in what we’ll discover next….!

NNHS Astronomy

Solar Eclipse.

Since its founding in 1876, the Northamptonshire Natural History Society has shared in one of astronomy’s most captivating pursuits: the observation of solar eclipses.

In an age before affordable travel and digital imaging, witnessing a total eclipse required determination and careful planning. In 1896, members of the Society undertook a remarkable journey to Norway to observe a total solar eclipse – travelling hundreds of miles in the hope of standing, briefly, in the Moon’s shadow. Expeditions like this reflected the spirit of curiosity and dedication that has long defined the NNHS.

That same spirit continues today. On 12 August 2026, a spectacular total solar eclipse swept across parts of Spain, Iceland and Greenland, while the UK experienced its deepest partial solar eclipse for decades. Across much of Britain, more than 94% of the Sun was covered as the eclipse reached its maximum close to sunset, creating one of the most dramatic astronomical sights visible from the UK in a generation. Many NNHS members travelled to the path of totality, while others gathered across Northamptonshire to witness this remarkable event.

While technology has transformed how we observe and record these events, the sense of wonder remains unchanged. From Victorian expeditions to modern-day observations, solar eclipses connect generations of naturalists and astronomers. They remind us that, however much the world changes, there are still moments when we all look up together in awe.

The Evolution of Telescopes

From the earliest optical instruments to today’s extraordinary space observatories, telescopes have transformed the way we see and understand the Universe.

When NNHS members travelled to Norway to observe the total solar eclipse of 1896, they worked with the telescopes and photographic equipment available at the time. More than a century later, instruments such as the James Webb Space Telescope can observe the Universe in infrared light, revealing objects and structures that earlier generations of astronomers could scarcely have imagined.

Launched in 2021, Webb is the largest telescope ever placed in space. Its 6.5-metre primary mirror collects faint infrared light from distant galaxies, forming stars and planetary systems, allowing astronomers to look billions of years into the past.

The technology may have changed beyond recognition, but the curiosity behind it remains the same – looking further, seeing more and discovering something new about our Universe.

Discover astronomy in the heart of Northampton

Explore the night sky with people who know it, love it and are always happy to share what they know.

Our experienced amateur astronomers bring a wealth of knowledge and practical observing experience, from the Solar System to distant galaxies, nebulae, star clusters and variable stars. Knowledge is freely shared, whether you want advice on observing and equipment, want to develop your existing skills, or are simply fascinated by what lies beyond our planet.

You don’t need to own a telescope or be an expert to join us. All levels of knowledge are welcome – from complete beginners to experienced observers.

Come along, ask questions, share what you know and discover more about the universe with us.

Clouds at Night

Have you ever noticed strange, silvery-blue clouds glowing in the Northamptonshire sky long after sunset?

They could be noctilucent clouds, also known as “night-shining clouds”. These remarkable clouds form around 80 km above the Earth – far higher than the everyday clouds that bring us our familiar Northamptonshire weather. Because they are so high, they can still catch the Sun’s light even when it is below the horizon for us.

The best chance of seeing them is on clear summer nights, usually low in the northern sky. Look for delicate, rippled or wave-like streaks that seem to glow against the darker twilight.

So next time you’re outside on a summer evening, take a look up – there’s always something new to notice, learn about and discover in the skies above Northamptonshire.

You don’t need any previous knowledge – just an interest in finding out more.
