Longest solar eclipse in 100 years to happen in 2027 - here's where to see it

Longest solar eclipse in 100 years to happen in 2027 - here's where to see it

Metro21-07-2025
If there's one thing that the Earth, Moon and Sun have in common, it's that they love to get their groove on.
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.'

Watch monstrous black hole GOBBLE up a star before Earth-shattering explosion in incredible new Nasa clip

Black holes come in a range of sizes, but can be up to 40 billion times bigger than the Sun, Live Science reports. According to Live Science, IMBHs are hard to spot and often confused with clusters of smaller black holes left over from collapsed stars. Researches also think they may hide behind small groups of stars that closely orbit them without being ripped apart. Therefore, the best way to spot an IMBH is indirectly, by measuring the masses of merging black holes or by catching them in the act consuming a star. In a study published April 11 in The Astrophysical Journal , researchers reported that they'd spotted another promising IMBH candidate, located more than 450 million light-years from Earth. By combining data from the Hubble Space Telescope and NASA's Chandra X-ray Observatory, the study team believes they have spotted a bright flash, or "tidal disruption event," caused by the black hole devouring a neighbouring star. However, as with many other IMBH candidates, it is not 100% certain that HLX-1 is real. In addition to being rare, IMBHs are important because of what they can tell us about other black holes. Yi-Chi Chang, a researcher at the National Tsing Hua University, said: "They represent a crucial missing link in black hole evolution between stellar mass and supermassive black holes." UK-led plan to build hypersonic plane that flies on edge of space at 4,000mph going from London to NYC in 60mins One theory is that they may start as large stellar-mass black holes and eventually grow into supermassive black holes over the course of billions of years. In a search for answers, astronomers are now on the lookout for more potential tidal disruption events on the edges of other galaxies.

Exact date 'hostile alien probe' could strike Earth revealed as Harvard scientist issues chilling warning

A Harvard scientist has issued a chilling warning about a mysterious interstellar object hurtling through our solar system, and says it could spell disaster for Earth. Professor Avi Loeb, who is well-known for pushing bold and often polarizing theories about extraterrestrial life, has been tracking the object, named 3I/ATLAS, since it was first spotted on July 1. If the object is an alien craft, Loeb warned it could be carrying a probe or even a weapon. He predicted that such an intercept vehicle would reach Earth between November 21 and December 5, 2025. The timeline is based on calculations that 3I/ATLAS will pass behind the sun from Earth's perspective this October, a time he ominously suggested could be used to prepare the attack. Referring to the object as a 'mothership,' he explained that its position would be an efficient way to seed habitable planets with probes. This strategy would allow the devices to 'intercept the planets while the mothership continues on its journey to the next star.' 'It may come to save us or destroy us. We'd better be ready for both options and check whether all interstellar objects are rocks,' said Loeb. Chris Lintott, an astronomer at the University of Oxford, has dismissed Loeb's claims as 'nonsense on stilts,' telling Live Science that the alien probe theory is an 'insult to the exciting work going on to understand this object.' Loeb has remained adamant that something about 3I/ATLAS does not add up. He said its retrograde orbit, meaning it's moving against the flow of the solar system, is oddly aligned with Earth's path. '3I/ATLAS might be an alien probe,' he said, citing its 'unusually rare trajectory,' which just so happens to align closely with the orbital plane of the inner planets, including Earth. He puts the odds of that happening naturally at just 0.2 percent. 'At its closest point to the sun on October 29, fears of an alien invasion could send stock markets crashing,' Loeb said. 'In that scenario, citizens would lose their trust in governments to protect them.' He went so far as to compare the potential chaos to a military ambush, saying: 'Facing a high-tech alien visitor could feel like Iran's air defenses when US B-2 bombers appeared, silent, unstoppable, and overwhelmingly powerful.' The object, believed to be about 12 miles wide, is unusually large for something hurtling in from outside the solar system. According to Loeb, if it were natural, we would have already spotted millions of similar objects. 'But we haven't,' he said. He has published three pre-print papers laying out the case and has even suggested that NASA attempt an interception using its Juno spacecraft when the object passes near Jupiter. 'In my view, we need a risk scale for interstellar objects,' Loeb said. 'A zero would be a natural comet. 'A 10 would be a verified technological object, possibly powered by an engine or emitting artificial light.' He also believes governments should already be forming task forces, including scientists, policymakers and even psychologists, to determine how to respond and how to break the news to the public without triggering panic. Loeb's warnings have grown increasingly urgent, culminating in one dramatic statement: 'It may come to save us or destroy us. We'd better be ready for both options.' If 3I/ATLAS is more than just a rock, he said Earth is woefully unprepared. 'The visitor,' he warned, 'is already in our backyard.' Even if the object turns out to be artificial, Loeb admitted there's little humanity could do. At nearly 60 miles per second relative to Earth, it's moving far too fast for any of our current rockets to reach. 'If the hypothesis that 3I/ATLAS is a technological artifact proves correct, there are two possible implications: either its intentions are entirely benign, or they are malign, said Loeb. 'In the first case, humanity need only wait and welcome this interstellar messenger with open arms. It is the second scenario that causes serious concern.' He added that because the second possibility has serious consequences, we can use the idea behind Pascal's wager. 'Blaise Pascal argued that it's smarter to believe in God because the possible benefits of believing are much greater than the losses if you're wrong,' Loeb explained. 'Similarly, in our case, it makes sense to warn humanity about the risk from 3I/ATLAS, even if it turns out to be just a theory.

Chilling theory emerges about suspicious activity in space... as Harvard expert warns we will tear ourselves apart: 'Time to worry'

A Harvard astrophysicist has sounded the alarm over an interstellar object hurtling toward Earth, warning humanity is unprepared if it turns out to be alien technology. Professor Avi Loeb, known for his controversial theories on extraterrestrial intelligence, has published three pre-print studies since the detection of the object, dubbed 3I/ATLAS, on July 1, 2025.
