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.'

Is THIS where aliens are hiding? Scientists discover a 'super–Earth' planet 35 light–years away – and it might have the right conditions to support life
It's one of the biggest unanswered questions in science. Are there aliens out there, and if so, where are they hiding? Now, researchers may have taken a huge step towards answering this question. Using NASA 's TESS space telescope, a team from Trottier Institute for Research on Exoplanets has detected a 'super–Earth' 35 light–years away that might be habitable. The planet, called L 98–59 f, is one of five worlds found orbiting a red dwarf star called L 98–59. However, it is the only one with the right conditions to support life. 'Finding a temperate planet in such a compact system makes this discovery particularly exciting,' said Charles Cadieux, lead author of the study. 'It highlights the remarkable diversity of exoplanetary systems and strengthens the case for studying potentially habitable worlds around low–mass stars.' The planet, called L 98–59 f, is one of five worlds found orbiting a red dwarf star called L 98–59 L 98–59 was first discovered in 2019, and was originally confirmed to have just four planets around it. However, by carefully reanalysing data collected from ground–based and space–based telescopes, the team was able to identify a fifth planet. This planet does not transit its host star – meaning it doesn't pass directly between us and the star. However, its presence was confirmed through subtle variations in the star's motion. The scientists believe the planet receives about the same amount of stellar energy as Earth does from the sun. Excitingly, this places it 'firmly' within the habitable zone – a region where water could remain in liquid form. The new study also sheds light on the four other planets orbiting the star. The innermost planet, L 98–59 b, is about 84 per cent the size of Earth, and about half its mass. Meanwhile, the two inner planets are believed to be similar to Jupiter's moon, Io, with extreme volcanic activity. Finally, the fourth planet may be a 'water world', the experts say. 'With its diversity of rocky worlds and range of planetary compositions, L 98–59 offers a unique laboratory to address some of the field's most pressing questions: What are super–Earths and sub–Neptunes made of?' asked René Doyon, co–author of the study. 'Do planets form differently around small stars? Can rocky planets around red dwarfs retain atmospheres over time?' Having found the fifth planet and learned more about the other four, the team now hopes to use James Webb – NASA's most powerful telescope – to study the star system in more detail. 'With these new results, L 98–59 joins the select group of nearby, compact planetary systems that we hope to understand in greater detail over the coming years,' said Alexandrine L'Heureux, co–author of the study. 'It's exciting to see it stand alongside systems like TRAPPIST–1 in our quest to unlock the nature and formation of small planets orbiting red dwarf stars.' PLANETARY SYSTEM L 98-59 The planetary system and its star - which are only around 35 light years away - are both called L 98-59. The planets in this system are the following, from closest to the star to further away: - L 98-59b: This rocky planet has half the mass of Venus (4.868×1024 kg). It's likely dry, but might have small amounts of water. It's smaller than the Earth but still bigger than Mars. - L 98-59c: Likely dry, but might have small amounts of water - L 98-59d: About 30 per cent of the mass of this planet could be water (but note that this would not be liquid water at the planet's surface) - L 98-59e: Has a 'year' of 12.8 days and is at least three times more massive than the Earth (a 'super-Earth'). Its temperature is thought to be only a few ten degrees warmer than that of the Earth. - L 98-59f: In the habitable zone of the star, meaning liquid water may exist at the surface of this planet

Mystery over 2,000-year-old shipwreck with ‘world's oldest computer' that inspired Indiana Jones as boat finally raised
The Antikythera wreck was first discovered in 1900 WRECK RIDDLE Mystery over 2,000-year-old shipwreck with 'world's oldest computer' that inspired Indiana Jones as boat finally raised Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) THE mystery deepens around the famous shipwreck that held the 2,000-year-old relic dubbed the "world's first computer". The Antikythera wreck sank in the first century BC off the Greek island that gave it its name, carrying a trove of treasure.

But researchers studying the shipwreck are now facing a new mystery after part of the wreck was recovered for the first time since 1976. The newly recovered timbers do not match those found in the 1970s - they differ in both size and construction. This has led scientists to consider the possibility that the Antikythera site may actually contain the remains of two separate shipwrecks - not just one. Read more world news ON THE BOTTOM Lost 300-yr-old ship with £101M worth of treasure FOUND off Madagascar coast Lorenz Baumer of the University of Geneva in Switzerland, who directed this year's expedition, said: 'The measures are different. 'The thickness of the planks found by Cousteau is around 10 centimetres, the ones we have measure around five - that's quite a difference. 'Now we have to find an explanation – is it another part of the ship? It's possible that they've been using thinner planks in upper parts, but that's pure speculation for now. 'Or is it – and for me this could be a possibility – a skiff. 'You see many of those merchant ships had smaller boats with them.' The Antikythera wreck was discovered in 1900 by Captain Dimitrios Kondos and his crew of sponge divers from the island of Symi. 7 The newly recovered timbers do not match those found in the 1970s, prompting scientists to question if there were two shipwrecks Credit: Credit: ESAG/UNIGE via Pen News Greek island offers to pay thousands to move there & you'll even get land Shortly after, over 300 other artefacts, including the Antikythera Mechanism, statues, coins and pieces of jewellery, were retrieved. For over a century, the mysterious device has left scientists scratching their heads. The conventional theory is that it was an ancient analogue device used to track the cycles of the Moon, Sun and planets and predict solar and lunar eclipses. Author Jo Marchant, who has written a book about the device, said it was 'probably the most exciting artefact that we have from the ancient world'. 7 A poster for 'Indiana Jones and the Dial of Destiny' (2023), starring Harrison Ford as Indiana Jones Credit: ©2023 Lucasfilm Ltd. & TM. All Rights Reserved. 7 A reconstruction of the Antikythera Mechanism on display at the exhibition of Ancient Greek Technology in Athens shows how sophisticated the device was Credit: AFP A fictional version of the device, renamed the Archimedes Dial, drives the plot in Harrison Ford's hit film, where Indiana Jones is shown diving at the Antikythera wreck. Dr Baumer said: 'It's total nonsense, but I was very well entertained I have to say.' But the theory that the ship carrying the mechanism was accompanied by a second ship has historical precedent. A technical drawing of two vessels - one towing the other - was found in Pompeii, inside the House of the Ship Europa, Dr Baumer said. He said: 'It's very detailed and very precise, so this drawing has been done by somebody who knows ships and also the technical parts. 'You see on the back of the Europa is hanging a smaller second ship.' He also mentioned the Biblical tale - when Paul the Apostle was shipwrecked off Malta, a lifeboat was launched from the main vessel. 'We have two wreck sites,' he said. 'Close to 200 meters southwards there is a huge field – it is all covered with amphorae. 'Chronologically the two sites go together so maybe these ships have been sailing together.' He added: 'We cannot tell if they sank one after the other, or if there was a couple of years, weeks, or days between them. 'But we see we are in about the same period.' The newly-recovered timbers have also revealed that the Antikythera wreck was already old when it sank. Analysis of the wood, which is elm and oak, dates it back to around 235 BC, whereas the ship didn't sink until around 80 BC. This year's expedition also uncovered a fragment of a sculpture depicting a nude male. Some believe the ship was doomed by the weight of the sculptures it carried. Dr Baumer said: 'It sunk very, very quickly because it was, in my opinion, totally overloaded. 'Whenever there's a storm in Antikythera, you're happy that you're not on board a ship, even a modern one. 'It is a very rocky coast, it's impossible to land, and you simply get broken up. There's no chance. 'Even now when the waves are too heavy, the ferry boats do not land on Antikythera – it's too dangerous.'

Asteroid the size of the Tower of Pisa to make close approach with Earth in days
If you've always wanted to see the Leaning Tower of Pisa, all you'll need to do is look up next week. An asteroid roughly the size of the famous Italian landmark is currently hurtling towards Earth at 46,908 miles per hour. The space rock, 2025 OW, will drift past our planet next Monday at a distance of 393,000 miles – about 1.6 times the distance to the Moon. Space officials estimate the rock is about 220 feet across, making it larger than the Leaning Tower of Pisa at 185 feet. 2025 OW is one of five 'planet-sized' asteroids getting up, close and personal with our planet over the next few days, Nasa says. The space agency's Asteroid Watch Dashboard says that 2025 OK1, which is estimated to be about 100 feet across, will fly past us today at a distance of 1,360,000 miles. Another airplane-sized asteroid, 2025-OZ, is also doing a drive-by visit of our home today. As you read this, it's about 3,340,000 miles away. On Saturday, two more giant asteroids will pass by Earth on Saturday: the 110-foot-wide 2025 OX will be 2,810,000 miles above your head. While 2025 OU1, about 140 feet across, will be slightly closer at 1,660,000 miles. But none of these rocks are anything to lose sleep over, astrophysicist, science journalist Alfredo Carpineti told Metro. 'There are over 13,000 near-Earth objects of comparative size that occasionally get near our planet,' the senior writer for IFLScience said. 'They could be dangerous if they hit Earth, but fortunately, these five will all fly well beyond the movement of the Moon.' Asteroids are lumps of rock, dust and metal left behind from the formation of our star system 4.6billion years ago. Most do laps around the Sun between Mars and Jupiter in the asteroid belt, some as small as rubble, and others hundreds of miles in diameter. Earth will be slammed by an asteroid about 300 feet once a decade, while one 10 times the size impacts us every 700,000 years. A space rock measuring just 160 feet in diameter can easily devastate the local area and pockmark the Earth, unleashing a force similar to a nuclear bomb – these happen once a millennium. The so-called 'city-killer' asteroid, 2024 YR4, which officials briefly feared had a 3.1% chance of colliding with Earth, is suspected to be 300 feet across. Our planetary defence options include intentionally smashing a satellite into it to nudge it off course or detonating a nuclear bomb near it. NASA's Jet Propulsion Laboratory in California and the Near-Earth Object Coordination Centre in Italy keep an eye on all these rocks whizzing about. They calculate the odds of an asteroid impact as they plot out the possible orbits, which get more accurate as they observe them more. More Trending This is exactly the case with 2025 OW, with scientists being able to predict its orbit for the next century. As of July, Nasa has discovered more than 38,600 near-Earth asteroids, of which 872 are larger than a kilometre. At least seven wandered close to Earth last month alone, with Nasa keeping an eye on 1,798 near-Earth objects on its 'risk list', though all have next to no chance of striking Earth. 'Still,' continued Carpineti, 'it's important we keep tracking them to know we will stay safe in the future.'
