Jodrell Bank and the Lovell space telescope
15 miles south of Manchester (England) city centre you’ll find a very large space telescope nestled in the heart of the rolling Cheshire countryside. This is the Jodrell Bank Observatory. A place that has fascinated us for years, it’s a kind of sleeping giant...always there but never seems to move. You can see the huge structure from the nearby road, there’s even a visitor centre, but it never really looks like it’s awake and doing anything. I mean what does it do? And why was it built?
Leading the way
Jodrell Bank is a testament to the UK's pioneering spirit within the world of radio astronomy and the cultural and scientific discoveries that this technology has realised - the discoveries that this incredibly powerful telescope has captured.
The iconic site is renowned for the huge Lovell Telescope, today it not only plays a crucial role in our understanding of the universe but also hosts the annual Bluedot Festival, where music, science and art converge in a celebration of curiosity and creativity.
So let's explore the history of Jodrell Bank, delve into the archives and celebrate the achievements and the people who pioneered these scientific breakthroughs.
The Birth of Jodrell Bank Observatory
The story of Jodrell Bank begins after World War II when the world was rebuilding, looking to the future and people were asking the bigger questions – exploring space and the universes beyond the stratosphere.
In 1945, Dr. Bernard Lovell, a physicist from the University of Manchester, set about finding a location close to Manchester that was quiet enough not to interfere with his cosmic ray research. Geeky fact, cosmic rays can be interrupted by radio transmissions, central Manchester with it’s strong history of independent music and radio, was not a great place geographically to study cosmic rays. Thankfully Lovell found the ideal spot at Jodrell Bank, which was a university-owned arboretum at the time.
Building the Lovell Telescope
By 1957, the Lovell Telescope, initially called the Mark I, stood as the world's largest steerable radio telescope. This is a colossal structure, a 76-meter diameter dish that remains a triumph of engineering and human ambition. To give you some perspective, the dish's surface area is equivalent to almost 1.5 football fields.
One of the telescope's first major achievements was to successfully track the Soviet Union's Sputnik 1 - the world's first satellite. The original ‘race for space’ marked the beginning of a new era of space exploration that saw Jodrell Bank become globally recognised as a centre of excellence in radio astronomy.
The Discoveries
Jodrell Bank's contributions to science are simply massive, we could list them all, and there’s better places to see them, here. Let’s just say that the observatory has played a pivotal role in numerous ground breaking discoveries. Ok, here we go, we're about to get geeky! Here are our highlights-
Quasars and Pulsars
In the 1960’s, Jodrell Bank was instrumental in the identification of quasars – these are extremely luminous objects a long, long way from earth. They are powered by supermassive black holes that are found at their centres. This discovery helped astronomers understand, interpret and map the scale and structure of the universe.
The observatory also made significant contributions to the study of pulsars - these are highly magnetised, rotating neutron stars that emit beams of electromagnetic radiation. In 1967, Jocelyn Bell Burnell and her team discovered the first pulsar, and the work carried out at Jodrell Bank along with the subsequent observations, were crucial in confirming their structure.
The people behind the dish.
Bernard Lovell and Jocelyn Bell Burnell - the Pioneers of the Cosmos
Sir Bernard Lovell was the driving force behind Jodrell Bank, he was a visionary whose contributions to science and technology cannot be underestimated. Born in 1913 in Gloucestershire, Lovell's early career was marked by his work on radar technology during World War II. After the war, his passion for radio astronomy led him to establish Jodrell Bank.
Away from work, (kind of) Lovell's dedication to understanding the universe was matched by his commitment to public engagement. He strongly believed in making science and the often complex astronomical concepts accessible to all. Lovell wanted to share this information, inspiring others, collaborating with them and exploring the collective opportunities.
Jocelyn Bell-Burnell was born in 1943 in Northern Ireland, she is another ‘tour de force’ who is closely associated with Jodrell Bank. Her discovery of pulsars in 1967, whilst studying at Cambridge University, revolutionised our understanding of neutron stars.
Despite her pivotal role, Bell Burnell was initially overlooked for the Nobel Prize, which was awarded to her male supervisors. Nevertheless, her dogged perseverance and extensive contributions to space science have now been widely recognised. She has received numerous accolades, including a Special Breakthrough Prize in Fundamental Physics in 2018.
Both Lovell and Bell Burnell embody the spirit of curiosity and resilience that drives scientific discovery. They are both pioneers, walking the path seldom taken, challenging the status quo and expanding our collective understanding. We love these people, they inspire us, there’s got to be at least three or four space themed DressCode shirts that we’d love to develop already.
Gravitational Lenses
In the 1970s, Jodrell Bank researchers contributed to the discovery of gravitational lenses, which occur when a massive object, such as a galaxy, bends the light from a more distant object, creating multiple images of the background source. This phenomenon not only provided evidence for Einstein's theory of general relativity but also offered a new method for studying the distribution of dark matter in the universe.
Alien adventures
Did you know that the universe is full of cosmic coincidences? And Jodrell Bank has had its fair share of serendipitous discoveries, including the detection of the Wow! signal in 1977. Whilst this phenomena was not first discovered at Jodrell Bank, it is the Jodrell Bank follow-up observations have added the intrigue.
IFYKYK The Wow! signal was a strong, narrowband radio signal first detected by the Big Ear radio telescope in Ohio, which some people speculated could be evidence of extraterrestrial life and intelligence. Despite extensive follow-up observations, including those carried out at Jodrell Bank, the source of the signal remains unexplained to this day.
Reimaging a space telescope for a Festival: BlueDot, where Science meets Sound
Jodrell Bank's scientific achievements are nothing short of spectacular, in recent years the site has evolved into a cultural landmark. Since 2016, the observatory has hosted the Bluedot Festival, an annual celebration that combines music, science, and art in a uniquely immersive experience.
An all star lineup
To date Bluedot Festival has boasted an eclectic line-up of musicians, from legendary rock bands to cutting-edge electronic artists including The Chemical Brothers, Kraftwerk, New Order and Jean-Michel Jarre have all headlined. Orbital, Leftfield, Bjork, Flaming Lips, Jon Hopkins, Metronomy and Mogwai have all also featured prominently. The Halle Orchestra are also in regular attendance and there has been a performance from the Paraorchestra too.
As you might imagine, with such a striking landmark, it’s no surprise that the festival's main stages are set against the stunning backdrop of the Lovell Telescope which creates an amazing audio-visual feast and a very special atmosphere.
Science rocks too
What sets Bluedot apart from other summer music festivals is its emphasis on science and education. Attendees can participate in talks, workshops, and demonstrations led by leading scientists, astronauts and creative thinkers. Topics range from the latest discoveries in astrophysics to discussions about climate change and sustainability. We’ve ‘shown our stripes’ at BlueDot, back in 2021 with the British Antarctic Survey.
Interactive installations
Bluedot is all about getting involved with science, climate, art, music and more. The festival features interactive art installations, virtual reality experiences and physical, hands-on science experiments. One of the more memorable installations was the "Luminarium," this labyrinth of inflatable structures created a mesmerising play of light and colour, inviting visitors to explore and reflect on this unique intersection of art and science. We simply cannot think of a more fitting venue for something like this.
Getting really Geeky
For the tech-savvy, science-loving attendees, Bluedot is a playground full of delights. Picture yourself dancing under the stars to the pulsating beats of electronica, with the iconic Lovell Telescope looming overhead like a giant cosmic plate, complete with footage from the deepest parts of space. Or imagine attending a lecture on the search for extra-terrestrial life, delivered by a renowned astronomer, and then heading to a silent disco where the DJ is an AI programme mixing tracks based on the movements of celestial bodies. It sounds other worldly and that’s exactly what BlueDot is about, pushing the boundaries, and that’s why we love it. BlueDot continues the innovation of the Jodrell site.
Jodrell Bank today and beyond
Today, Jodrell Bank continues to push the boundaries of our understanding of the universe. It is part of the e-MERLIN array - a network of seven radio telescopes across the UK. It also plays a key role in the international Square Kilometre Array (SKA) project, which aims to build the world's largest radio telescope.
Preserving a Legacy
In 2019, Jodrell Bank was awarded UNESCO World Heritage status, recognising its outstanding contribution to science and the importance of the site as a place of cultural and historical significance. Ensuring that Jodrell Bank's legacy will be preserved for future generations to explore as well.
The future of Jodrell Bank
Looking ahead, Jodrell Bank is set to remain at the forefront of radio astronomy. The observatory is continuously upgrading its facilities and equipment to keep pace with advancements in scientific research. As we enter a new era of space exploration with missions to Mars, the Moon and beyond, Jodrell Bank will undoubtedly continue to play a pivotal role in unraveling the mysteries of the cosmos.
