Longest solar eclipse in 100 years to happen in 2027 - here's where to see it
The three celestial bodies are forever dancing around the cosmos and, every now and then, they line up perfectly, creating an eclipse.
A solar eclipse is when the Moon slides between us and the Sun, casting a shadow of wonder as only the wispy, outer edges of the Sun are visible.
Eclipses can remind us all of our place in the lonely, messy cosmos – after all, they only happen because the Moon is 400 times smaller than the Sun, but is 400 times closer to us.
They tend to last 10 seconds or so, but in only a couple of years, one of the longest and most significant eclipses of the 21st century will happen.
The solar eclipse will take place on August 2, 2027, in 10 countries.
This one will be a total solar eclipse, when the Sun fully disappears behind the Moon. The moment this happens is called totality.
A line of totality will then slowly drift across the world, where for a few brief minutes the Moon will fully block out the Sun, and darkness will swallow the light of day.

Six minutes, which in the world of cosmic coincidences is a seriously long time, said Greg Brown, a senior astronomer at the Royal Museums Greenwich, told Metro.
'It varies from only a few seconds at its shortest to a theoretical maximum of 7.5 minutes,' he said. 'This variation is due to the Moon and Sun varying in apparent size, itself due to their slightly changing distance from the Earth during the Moon's orbit around the Earth and the Earth's orbit around the Sun.'
But how long stargazers will have to crane their necks will depend on where they live.
The total solar eclipse will only be visible across a thin, 160-mile-long strip of southern Europe and northern Africa where 89 million live, according to Timeanddate.com.
The skies will begin to darken above the Atlantic Ocean at 05.19am (UTC), just as the Sun is rising.
While this is where totality begins, it's not where it will be the longest. As the two cosmic giants do their dance and the Earth spins, totality will only be visible above the Atlantic for three minutes.
The Moon's 258km-wide shadow will then be cast in the aptly-named Costa de la Luz, or 'Coast of the Light', in Spain's Andalusia before gobbling up the British Overseas Territory of Gibraltar.
It will also envelop Morocco, Algeria, Tunisia, Libya and Egypt, where it will reach its deepest, longest duration at 6 minutes and 22 seconds from 12.44pm (UTC).
For one, please don't stare directly at the Sun, which can permanently damage your eyes.
Even if the Moon has completely obscured the Sun, the risk is still high. People can look at the celestial event using eclipse glasses.
You can also project the eclipse onto the ground using items around the house, such as a cardboard box, a kitchen strainer or even your fingers.
After it leaves Egypt, the total eclipse will be around four to three minutes as the shadow glides through the Red Sea, Saudi Arabia and Yemen.
The eclipse will end with a totally eclipsed sunset near the Chagos Archipelago in the Indian Ocean.
Some nations just to the north or south of the totality line will be able to see a partial solar eclipse, when the Moon takes a smaller bite out of the Sun.
Brown said that the UK sadly won't catch a glipse of utality – the nation is far too north of the line.
We will have another partial solar eclipse, with around 40% of the Sun covered in the south of England dropping to around 20% in northern Scotland,' he added.
'The partial eclipse will begin around 9.20am for us in the UK, ending around 10.50am with the maximum occurring around 10am.
The 2027 eclipse will be around 16 seconds shorter than the July 22 2009, eclipse, Brown said, the longest solar eclipse this century.
'However, while the 2009 eclipse was longer, it occurred almost entirely over the ocean, making it very difficult to observe,' he said.
Skywatchers have been claiming online that the world will be plunged into darkness for six minutes on August 2 this year.
But this isn't the case, according to astronomical data. It seems users have simply got the year of the lengthy eclipse wrong.
Nasa says the next eclipse, a partial one, will happen on September 21, blanketing Australia, Antarctica and the Pacific and Atlantic Oceans. More Trending
The soonest total eclipse will be August 12, 2026. It will only be visible in a sliver of Greenland, Iceland, Spain and Russia, while Europe, Africa and North America will be treated with a partial solar eclipse.
This eclipse, Brown said, is Britain's 'best bet' for seeing this awe-inspiring sight.
'The whole of the UK will experience at least a 90% eclipse and Cornwall experiencing a 96% eclipse,' he said. 'Definitely one to look out for.'

What we know about the search for ‘Planet Nine' in our solar system
Is there a massive undiscovered planet on the outer reaches of the Solar System? The idea has been around since before the discovery of Pluto in the 1930s. Labelled as planet X, prominent astronomers had put it forward as an explanation for Uranus 's orbit, which drifts from the path of orbital motion that physics would expect it to follow. The gravitational pull of an undiscovered planet, several times larger than Earth, was seen as a possible reason for the discrepancy. That mystery was ultimately explained by a recalculation of Neptune 's mass in the 1990s, but then a new theory of a potential Planet Nine was put forward in 2016 by astronomers Konstantin Batygin and Mike Brown at Caltech (the California Institute of Technology). Their theory relates to the Kuiper Belt, a giant belt of dwarf planets, asteroids and other matter that lies beyond Neptune (and includes Pluto). Many Kuiper Belt objects – also referred to as trans-Neptunian objects – have been discovered orbiting the Sun, but like Uranus, they don't do so in a continuous expected direction. Batygin and Brown argued that something with a large gravitational pull must be affecting their orbit, and proposed Planet Nine as a potential explanation. This would be comparable to what happens with our own Moon. It orbits the Sun every 365.25 days, in line with what you would expect in view of their distance apart. However, the Earth's gravitational pull is such that the Moon also orbits the planet every 27 days. From the point of view of an outside observer, the Moon moves in a spiralling motion as a result. Similarly, many objects in the Kuiper Belt show signs of their orbits being affected by more than just the Sun's gravity. While astronomers and space scientists were initially sceptical about the Planet Nine theory, there has been mounting evidence, thanks to increasingly powerful observations, that the orbits of trans-Neptunian objects are indeed erratic. As Brown said in 2024, 'I think it is very unlikely that P9 does not exist. There are currently no other explanations for the effects that we see, nor for the myriad other P9-induced effects we see on the Solar System.' In 2018, for example, it was announced that there was a new candidate for a dwarf planet orbiting the Sun, known as 2017 OF201. This object measures around 700km across (Earth is roughly 18x bigger) and has a highly elliptical orbit. This lack of a roughly circular orbit around the Sun suggested either an impact early in its lifetime that put it on this path, or gravitational influence from Planet Nine. Problems with the theory On the other hand, if Planet Nine exists, why hasn't anyone found it yet? Some astronomers question whether there's enough orbital data from Kuiper objects to justify any conclusions about its existence, while alternative explanations get put forward for their motion, such as the effect of a ring of debris or the more fantastical idea of a small black hole. The biggest issue, however, is that the outer Solar System just hasn't been observed for long enough. For example, object 2017 OF201 has an orbital period of about 24,000 years. While an object's orbital path around the Sun can be found in a short number of years, any gravitational effects probably need four to five orbits to notice any subtle changes. New discoveries of objects in the Kuiper Belt have also presented challenges for the Planet Nine theory. The latest is known as 2023 KQ14, an object discovered by the Subaru telescope in Hawaii. It is known as a 'sednoid', meaning it spends most of its time far away from the Sun, though within the vast area in which the Sun has a gravitational pull (this area lies some 5,000AU or astronomical units away, where 1AU is the distance from the Earth to the Sun). The object's classification as a sednoid also means the gravitational influence of Neptune has little to no effect on it. 2023 KQ14's closest approach to the Sun is around 71AU away, while its furthest point is about 433AU. By comparison, Neptune is about 30AU away from the Sun. This new object is another with a very elliptical orbit, but it is more stable than 2017 OF201, which suggests that no large planet, including a hypothetical Planet Nine, is significantly affecting its path. If Planet Nine exists, it would therefore perhaps have to be farther than 500AU away from the Sun. To make matters worse for the Planet Nine theory, this is the fourth sednoid to be discovered. The other three also exhibit stable orbits, similarly suggesting that any Planet Nine would have to be very far away indeed. Nonetheless, the possibility remains that there could still be a massive planet affecting the orbits of bodies within the Kuiper Belt. But astronomers' ability to find any such planet remains somewhat limited by the restrictions of even unmanned space travel. It would take 118 years for a spacecraft to travel far enough away to find it, based on estimates from the speed of Nasa's New Horizons explorer. This means we'll have to continue to rely on ground- and space-based telescopes to detect anything. New asteroids and distant objects are being discovered all the time as our observing capabilities become more detailed, which should gradually shed more light on what might be out there. So watch this (very big) space, and let's see what emerges in the coming years. Ian Whittaker is a Senior Lecturer in Physics at Nottingham Trent University.

The avoidable health problem causing thousands of children to miss school
Dog eats homework, overslept alarms and a case of the flu are what come to mind when thinking of reasons a child skips school. But it turns out many parents – and teachers – might be be in the dark about a crucial health issue causing kids to take time off. Scientists have revealed that tooth decay is seeing pupils lose hours of valuable lesson time. And the poorest children are the worst affected. A study of over 260,000 Scottish children found that children with tooth decay missed on average five more half-days of school per year than those with healthy teeth. A third of children – more than 85,000 – were suffering from poor oral health. Absences grew longer with worsening dental problems. Mariel Goulart, a dentist who led the research for Glasgow University, told Metro: 'Missing school, even just half-days, can hurt a child's learning. 'This study shows that fixing tooth decay isn't just about health, it's about giving kids a fair chance in school, especially in deprived communities.' The problem was revealed by researchers in Scotland, but they warn that it could be even worse in England. Children who needed emergency treatment for their teeth or had to have them removed under general anaesthetic lost more than three days of lessons. Of the four to seven-year-olds being studied who had tooth decay, they missed on average 22 half days, or 11 full days at school. Those without tooth decay missed only 15 half-days or seven full days. When researchers adjusted these results to account for other factors, they found children with tooth decay missed on average five more half-days of school per year. One in five children aged 5 in England suffers from tooth decay, and this new study indicates that 140,000 children in that age group alone could therefore be at risk of longer school absences. The most concerning finding, however, was how children from poorer backgrounds could miss even more school due to dental hygiene. Kids in the poorest areas missed nearly twice as many days compared to those in wealthier areas, researchers found. Goulart said: 'I honestly didn't think it would be this much. 'Child poverty is something that is really important for oral health and education outcomes are related to income levels.' She explained: 'What about the days when children were at school but in pain? Were they paying attention to the classroom? I don't think so.' As a result, the researcher is calling for free school meals to be rolled out more widely across the UK. 'Free school meals should be available for every child, despite personal income,' she said. 'If you have a healthy meal, it is one time less a day that you eat sugar, biscuits or anything that's harmful for your teeth.' Scotland Scotland introduced a supervised toothbrushing programme, called Childsmile in nurseries and schools from 2008. Childsmile offers supervised toothbrushing, fluoride varnish application and dietary advice to children in schools and dentists. The latest National Dental Inspection Programme results show 73 per cent of Primary 1 children (reception in English education) have no obvious tooth decay compared with 58 percent in 2008, when Childsmile was introduced. England A similar toothbrushing programme was only rolled out in England in March 2025. It aims to reach up to 600,000 children in most deprived areas. Goulart told Metro the delay in introducing a toothbrushing scheme meant the number of children missing school due to dental issues could be higher in England than across the border. The government's new scheme aims to give 600,000 children in the most deprived areas access to supervised toothbrushing. Health minister Stephen Kinnock said it is 'shocking' that a third of five-year-olds in the most deprived areas have experience of tooth decay. Labour plans to reform the dental contract to get dentists to provide more NHS work include: • Providing 23 million free toothbrushes and toothpastes to reach up to 600,000 children each year. More Trending • Rolling out 700,000 extra urgent dental appointments for those who need treatment A Scottish Government spokesperson praised the 15 percent improvement in dental hygiene since the introduction of Childsmile. They told Metro: 'Every child should be able to attend school feeling comfortable, confident, and ready to learn, and this research highlights the importance of oral improvement programmes in education settings.'

Here's how to see the Delta Aquariid meteor shower in the UK this week
Stargazers are in for a treat as a breathtaking meteor shower peaks across the UK this week. The Delta Aquariid, also known as the Southern Delta Aquariids, will light up the sky most brightly tomorrow night. While the meteor shower is more visible, as its name implies, in the Southern Hemisphere, the UK and the wider Northern Hemisphere can still catch a good show, experts told Metro. Some meteor showers are caused by comets, dirty snowballs made of the leftovers from the start of our solar system around 4.6billion years ago. Comets leave behind trails of ice and rock that linger in space years after they leave, said Dr Cyrielle Opitom, of the Institute for Astronomy at the University of Edinburgh. She told Metro: 'Small dust particles left behind then enter the atmosphere and become meteors. This is usually the source of meteor showers. 'Other times, random small asteroids or pieces of rock not related to a comet enter the atmosphere and can also become meteors.' When the comet waste enters the atmosphere, it hits the sky at such speed that it bursts into flames, causing a celestial fireworks display. Scientists aren't 100% sure which comet is behind the Delta Aquariid, though they suspect it's from the 3.7-mile-wide Comet 96P Machholz, says Charlotte Bays, the secretary of the space rock monitoring group UK Fireball Alliance. The shooting stars case occurs as the Earth 'passes through the stream of debris shed' by the snowball, said Bays. 'It is also what we call a 'short-period' comet, completing an orbit every 5.24 years; this year,' she added. The debris you're seeing isn't from the comet passing by; it's just the trail it left behind years ago. The next time Comet 96P Machholz will glide past us is June 16, 2028. Astronomers named the shower after the constellation Aquarius and its brightest star, Delta Aquarii, which is the point of the sky from which the meteors seem to come. Typically, the Earth passes through the cosmic rubble from late July to early August. This year, the shower will peak on the night of Tuesday July 30, but remain visible until August 23. The peak, which is when Earth reaches the densest part of the cosmic debris, is the best chance to see the meteor shower, explained Charlotte Bays, the secretary of the monitoring group UK Fireball Alliance. Stargazers can expect up to 20 meteors an hour for days with a dark sky and no pesky Moon. About one in 10 Delta Aquariid meteors have persistent trains, glowing gassy trails that give these space rocks their iconic shape. While you might assume you need a fancy telescope or binoculars to see the meteors, the naked eye is best, as the tech limits your field of vision. To see a meteor shower you need to get to a place that has a clear view of the night sky, recommended Dr Edward Bloomer, senior astronomer at the Royal Observatory Greenwich. Ideally, that's as far away as possible from cities, street lights and traffic. Planetariums, astronomy clubs or even maps like this one for light pollution and this for nighttime brightness can help. But stargazers have two other foes – the weather and the Moon. So, it's always best to check the weather report for that night as well as how visible the Moon will be. Be prepared for long stretches where nothing happens, Dr Bloomer half-joked, 'or little flurries of activity where you see several in quick succession'. 'The appearance is of a short-lived streak of light ('shooting stars' is pretty apt!) that will be radiating outwards from a point,' he added. 'Importantly, unless you've set up with recording equipment, a shooting star only lasts long enough for quite a personal experience: there's no time really to point it out to anyone before it will have disappears. 'It's always fun to go out and have a look with others, but you'll all have a unique encounter!' More Trending Dr Bloomer stressed, however, that the constellation Aquarius is fairly low on the horizon, which might make seeing the shower tricky. 'But it's not impossible,' he added. 'The number one thing is to give yourself time to adjust to the dark (put your phone away!) and be prepared to wait. 'The randomised arrival of the shooting stars means you need to have a little patience.'
