When will the next total solar eclipse be visible in the UK?
On 2 August, 2027, parts of southern Europe will see a total solar eclipse.
It won;t be quite as spectacular in the UK. Londoners will experience a 42% eclipse - with the sun appearing as a crescent. People in the Scilly Isles will see a partial eclipse of 48%, while those in the Shetlands will see a 13% eclipse.
In a partial eclipse, the sky will not go dark, but shadows might look different, and the sun is visibly 'blocked' by the moon - while a total eclipse offers a few minutes of darkness which often provokes audible gasps.
The total eclipse will see areas such as the Straits of Gibraltar, North Africa and the Arabian Peninsula, with up to six minutes, 23 seconds of 'totality'. Luxor in Egypt and Mecca in Saudi Arabia are among the areas on the path of totality, according to Sky at Night magazine.
Despite online reports this week, which possibly mixed up the events in 2027, there is most definitely no eclipse in August 2025 - the only eclipse this year came earlier, when the UK saw a partial eclipse with up to 30% eclipse on 29 March 2025.
When will the next total solar eclipse be in the UK?
Next year will see a partial eclipse on 12 August, 2026, with the eclipse peaking at 96% in the Scilly Isles. Most areas in the UK will see an 89% eclipsed sun.
But if you're waiting for a proper total solar eclipse in the UK, you're in for rather a long wait (and it will also help to be young at this point) as the next one will not be until 23 September, 2090, when it will be visible from southern England and southern Ireland.
What happens during a total solar eclipse?
Total solar eclipses happen when the moon completely covers the sun, and is only visible from a certain area (known as 'the path of totality').
Areas nearby witness a partial eclipse instead.
The reason it happens is that the moon is 400 times smaller than the sun, and also 400 times closer to us than the Sun (by complete coincidence), so that they appear 'the same size' at the time of an eclipse.
In the darkest part of the shadow, the Sun's light is almost completely blocked out.
NASA says, 'People viewing the eclipse from locations where the Moon's shadow completely covers the Sun – known as the path of totality – will experience a total solar eclipse. The sky will become dark, as if it were dawn or dusk.
'Weather permitting, people along the path of totality will see the Sun's corona, or outer atmosphere, which is usually obscured by the bright face of the Sun.'
Some observers report feeling a chill, and birds stopping singing because they think it's night time.
The last total solar eclipse in the UK was in 1999, although it was only visible from Cornwall and the Scilly isles, according to the Royal Observatory.
Patchy weather meant that only some eclipse-watchers got a good sight of the eclipse (and some were soaked with rain instead).
The Guardian describes how 'gasps of amazement' rang out in Penzance as totality descended for two minutes and six seconds.

Rhino horns turned radioactive to fight poachers in South Africa
South African scientists have launched an anti-poaching campaign in which rhino's horns will be injected with a radioactive material. The group, from the University of the Witwatersrand, said the process is harmless to rhinos but will allow customs officers to detect smuggled horns as they're transported across the world. South Africa has the largest rhino population in the world, and hundreds of the animals are poached there every year. The university's venture, called the Rhisotope Project, was launched on Friday after six years of research and testing. "Our goal is to deploy the Rhisotope technology at scale to help protect one of Africa's most iconic and threatened species," said Jessica Babich, head of the Rhisotope Project. "By doing so, we safeguard not just rhinos but a vital part of our natural heritage." Tests conducted in the pilot study, which involved 20 rhinos, confirmed that the radioactive material was not harmful to the animals. "We have demonstrated, beyond scientific doubt, that the process is completely safe for the animal and effective in making the horn detectable through international customs nuclear security systems," said James Larkin a professor at Wits University who is also part of the project. The horns of African rhinos are often exported to Asian markets were they are used in traditional medicine and also seen as a status symbol. White rhinos are considered threatened, while black rhinos are critically endangered.

Light pollution is making it harder for astronomers to study the universe
Outdoor lighting for buildings, roads and advertising can help people see in the dark of night, but many astronomers are growing increasingly concerned that these lights could be blinding us to the rest of the universe. Hot science in the cold, dark night While orbiting telescopes like the Hubble Space Telescope or the James Webb Space Telescope give researchers a unique view of the cosmos—particularly because they can see light blocked by the Earth's atmosphere—ground-based telescopes also continue to drive cutting-edge discovery. Telescopes on the ground capture light with gigantic and precise focusing mirrors that can be 20 to 35 feet wide. Moving all astronomical observations to space to escape light pollution would not be possible, because space missions have a much greater cost and so many large ground-based telescopes are already in operation or under construction. Around the world, there are 17 ground-based telescopes with primary mirrors as big or bigger than Webb's 20-foot mirror, and three more under construction with mirrors planned to span 80 to 130 feet. The newest telescope starting its scientific mission right now, the Vera Rubin Observatory in Chile, has a mirror with a 28-foot diameter and a 3-gigapixel camera. One of its missions is to map the distribution of dark matter in the universe. To do that, it will collect a sample of 2.6 billion galaxies. The typical galaxy in that sample is 100 times fainter than the natural glow in the nighttime air in the Earth's atmosphere, so this Rubin Observatory program depends on near-total natural darkness. Any light scattered at night—road lighting, building illumination, billboards—would add glare and noise to the scene, greatly reducing the number of galaxies Rubin can reliably measure in the same time, or greatly increasing the total exposure time required to get the same result. The LED revolution Astronomers care specifically about artificial light in the blue-green range of the electromagnetic spectrum, as that used to be the darkest part of the night sky. A decade ago, the most common outdoor lighting was from sodium vapor discharge lamps. They produced an orange-pink glow, which meant that they put out very little blue and green light. Even observatories relatively close to growing urban areas had skies that were naturally dark in the blue and green part of the spectrum, enabling all kinds of new observations. Then came the solid-state LED lighting revolution. Those lights put out a broad rainbow of color with very high efficiency, meaning they produce lots of light per watt of electricity. The earliest versions of LEDs put out a large fraction of their energy in the blue and green, but advancing technology now gets the same efficiency with 'warmer' lights that have much less blue and green. Nevertheless, the formerly pristine darkness of the night sky now has much more light, particularly in the blue and green, from LEDs in cities and towns, lighting roads, public spaces, and advertising. The broad output of color from LEDs affects the whole spectrum, from ultraviolet through deep red. The U.S. Department of Energy commissioned a study in 2019 which predicted that the higher energy efficiency of LEDs would mean that the amount of power used for lights at night would go down, with the amount of light emitted staying roughly the same. But satellites looking down at the Earth reveal that just isn't the case. The amount of light is going steadily up, meaning that cities and businesses were willing to keep their electricity bills about the same as energy efficiency improved, and just get more light. Natural darkness in retreat As human activity spreads out over time, many of the remote areas that host observatories are becoming less remote. Light domes from large urban areas slightly brighten the dark sky at mountaintop observatories up to 200 miles away. When these urban areas are adjacent to an observatory, the addition to the skyglow is much stronger, making detection of the faintest galaxies and stars that much harder. When the Mount Wilson Observatory was constructed in the Angeles National Forest near Pasadena, California, in the early 1900s, it was a very dark site, considerably far from the 500,000 people living in Greater Los Angeles. Today, 18.6 million people live in the L.A. area, and urban sprawl has brought civilization much closer to Mount Wilson. When Kitt Peak National Observatory was first under construction in the late 1950s, it was far from metro Tucson, Arizona, with its population of 230,000. Today, that area houses 1 million people, and Kitt Peak faces much more light pollution. Even telescopes in darker, more secluded regions—like northern Chile or western Texas—experience light pollution from industrial activities like open-pit mining or oil and gas facilities. The case of the European Southern Observatory An interesting modern challenge is facing the European Southern Observatory, which operates four of the world's largest optical telescopes. Their site in northern Chile is very remote, and it is nominally covered by strict national regulations protecting the dark sky. AES Chile, an energy provider with strong U.S. investor backing, announced a plan in December 2024 for the development of a large industrial plant and transport hub close to the observatory. The plant would produce liquid hydrogen and ammonia for green energy. Even though formally compliant with the national lighting norm, the fully built operation could scatter enough artificial light into the night sky to turn the current observatory's pristine darkness into a state similar to some of the legacy observatories now near large urban areas. This light pollution could mean the facility won't have the same ability to detect and measure the faintest galaxies and stars. Light pollution doesn't only affect observatories. Today, around 80% of the world's population cannot see the Milky Way at night. Some Asian cities are so bright that the eyes of people walking outdoors cannot become visually dark-adapted. In 2009, the International Astronomical Union declared that there is a universal right to starlight. The dark night sky belongs to all people—its awe-inspiring beauty is something that you don't have to be an astronomer to appreciate.

Why South Africa is injecting Rhino horns with radioactive isotopes
South Africa has launched an innovative anti-poaching campaign, injecting rhino horns with radioactive isotopes to deter illegal trafficking. The University of the Witwatersrand, alongside nuclear energy officials and conservationists, initiated the project on Thursday, with five rhinos receiving the harmless isotopes. These are designed to be detectable by customs agents. The university hopes this marks the start of a mass injection programme for the nation's declining rhino population. Last year, about 20 rhinos at a sanctuary were injected with isotopes as part of initial trials that paved the way for Thursday's launch. The radioactive isotopes even at low levels can be recognised by radiation detectors at airports and borders, which can lead to the arrest of poachers and traffickers. Researchers at Witwatersrand's Radiation and Health Physics Unit say that tests conducted throughout the pilot study confirmed that the radioactive material was not harmful to the animals. 'We have demonstrated, beyond scientific doubt, that the process is completely safe for the animal and effective in making the horn detectable through international customs nuclear security systems,' said James Larkin, chief scientific officer of the Rhisotope Project. 'Even a single horn with significantly lower levels of radioactivity than what will be used in practice successfully triggered alarms in radiation detectors,' said Larkin. The tests also confirmed that individual horns could be detected inside full 40-foot shipping containers, he said. The International Union for Conservation of Nature, an international conservation body, estimates that the global rhino population stood at around 500,000 at the beginning of the 20th century but has now declined to around 27,000 due to continued demand for rhino horns on the black market. South Africa has the largest population of rhinos with an estimated 16,000 but the country experiences high levels of poaching with about 500 rhinos killed for their horns every year. Private and public rhino owners and conservation authorities have been urged approach the university to have their rhinos injected.
