World-class Jodrell Bank is under threat and UK risks a physics brain drain
The UK could lose the Jodrell Bank observatory and its e-Merlin radio telescope network as the Science and Technology Facilities Council plans to withdraw funding by March 2028, with astronomers warning of devastating consequences for British science.

STFC funding cuts threaten to close Jodrell Bank and the e-Merlin network, slash UK participation in the Rubin observatory and Event Horizon Telescope, and trigger an exodus of early-career physicists from Britain.
Britain has a giant space telescope and other science labs that help us learn about stars, black holes, and tiny particles. The government is running out of money, so it might have to turn off these big science machines. That could make young scientists want to move to other countries, like a soccer team losing its best players.

A Telescope Network Built Over Decades, Now Facing Closure
The threat to Jodrell Bank and the e-Merlin network represents a turning point for British radio astronomy. From Bernard Lovell's wartime radar work in the Cheshire countryside in 1945 to the Lovell telescope tracking Sputnik in 1957, the observatory has been a cornerstone of global astronomy for 80 years. Pulling STFC funding in March 2028 would not just dim a single dish — it would dissolve a seven-telescope national capability that has driven discoveries from spinning neutron stars to the faint afterglow of the big bang. Astronomers interviewed by the Guardian converged on the same words: devastating, shocking, disastrous.
Radio astronomy is not an abstract, ivory-tower pursuit. The technique has revealed matter swirling around supermassive black holes and mapped the large-scale structure of the universe. The UK helped build the modern observational landscape; losing e-Merlin would leave a hole in that landscape that other nations are unlikely to fill, and that the UK would find expensive to rebuild once the scientists and engineers have dispersed.
A Funding Squeeze Compounded by Cost Overruns
The STFC says it must find £162m in savings by 2030, but figures obtained by Research Professional News suggest the underlying shortfall is far larger, with a combined forecast cost overrun of £684m across the four years of the government's latest spending review period. Rising electricity bills, soaring staff costs, and unfavorable foreign exchange rates on international subscriptions such as the UK's Cern contribution have combined into a structural deficit rather than a one-off shortfall.
The result is an across-the-board retrenchment. UK involvement in the Rubin observatory in Chile, which this month began a decade-long survey to record the largest cosmic movie ever, will drop 20%. Work on the Bison solar observation network is being cut by 40%, and the country is withdrawing from the Event Horizon Telescope that produced the first image of a black hole. The Clara particle accelerator test facility in Cheshire is being mothballed, the operating budget for the Boulby underground science facility is being slashed by 40%, and there is no funding for the LHCb experiment, which could terminate early with 80% of its data uncollected. The Diamond synchrotron and the Isis neutron source in Oxfordshire face cuts but will remain operational.
A Brain Drain That Would Outlast the Budget Cycle
The most damaging cost may be human. A recent survey found that nearly 80% of early-career physicists are considering leaving the UK in the wake of the funding crisis. Once a generation of researchers relocates to facilities in the United States, continental Europe, or Asia, the institutional knowledge and training pipelines erode in ways that compound over decades. The best scientists, the article notes, will go wherever the best science can be done.
Pulling out of international collaborations does more than remove the UK from those projects — it signals to young researchers that careers in British physics face a narrowing horizon. Reversing that perception will require not just restored budgets but a credible, multi-year plan. Without one, the savings realised in the 2028 spending round may show up decades later as forfeited discoveries and a slower-growing science economy.
Key points
- The STFC plans to withdraw funding from Jodrell Bank and the e-Merlin radio telescope network by March 2028, with all observations due to stop unless alternative support is found.
- The funding shortfall stems from cost overruns of an estimated £684m over the spending review period, driven by electricity, staff costs, and foreign exchange rates on international subscriptions such as Cern.
- The UK is cutting involvement in the Rubin observatory in Chile by 20%, reducing the Bison solar network by 40%, withdrawing from the Event Horizon Telescope, and mothballing the Clara accelerator test facility in Cheshire.
- There is no funding for the LHCb experiment at the Large Hadron Collider, which could terminate early with 80% of its data uncollected, while the Diamond synchrotron and Isis neutron source face cuts but remain operational.
- A recent survey found that nearly 80% of early-career physicists are considering leaving the UK, raising the prospect of a long-term brain drain in fundamental science.
The STFC has framed the cut as conditional — observations would only stop if no alternative support is found before March 2028, leaving a window for universities, private donors, or international partners to step in. If the UK secures even partial alternative funding and signals a longer-term science plan, some of the planned cuts could be softened and the worst-case brain drain averted.
If the projected £684m overrun materialises and no alternative funding emerges, Jodrell Bank and e-Merlin could close, the UK would withdraw from the Event Horizon Telescope and LHCb, and the Boulby underground lab would lose 40% of its operating budget. With nearly 80% of early-career physicists already considering leaving, the loss of a generation of talent could permanently erode Britain's standing in fundamental physics.
