EXCLUSIVE Do aliens exist? British astronaut Tim Peake thinks there IS 'complex, intelligent life' beyond Earth - and says we're 'close' to finding it
If aliens exist, surely Tim Peake is one of a select group of humans who have been the closest to them.
The British astronaut spent six months in space between 2015 and 2016, living and working on the International Space Station (ISS), 250 miles above Earth.
Although he didn't have any extraterrestrial encounters while up there, Major Peake said he thinks aliens most likely do exist.
Speaking exclusively to MailOnline, the 53-year-old, from Chichester in Sussex, said Earth is 'actually a pretty small place', relatively speaking.
'When you look at just our own Milky Way galaxy with 200 billion stars, that's one of a number of hundreds of billions of galaxies that we can see,' he told MailOnline.
'So the chances are that there is complex, intelligent life elsewhere in the universe.'
In April, scientists revealed that a faraway planet called K2-18b has large quantities of chemicals in its atmosphere that are suggestive of living organisms.
Although the findings are to be confirmed, Major Peake said we are likely close to finding the definitive proof that aliens do exist.
'We know that the universe is abundant with water, it's abundant with the seeds of life,' the British spaceman told MailOnline.
'We've discovered so many thousands of exoplanets in our neighbourhood which are orbiting stars, many of which have very good signs of potential habitability with liquid oceans for example.
'Within the next five to 10 years, using the James Webb Space Telescope for example, we could even get to the situation where scientists feel confident enough to be able to say that they found signs of biological life on another planet.'
'It might be small bacteria, it might be algae, giving off some signs of biological processes.
'But that's the kind of thing that we're getting close to be able to say for sure.'
During his time on the ISS between December 2015 and June 2016, Major Peake completed the first British spacewalk, took part in 250 research experiments, and even managed to remotely run the London Marathon.
On January 15, 2016, he participated in the first spacewalk outside the ISS by a British astronaut with the dazzling blue of the Earth beneath him.
The historic event lasted nearly five hours, although it was cut short when American colleague Tim Kopra had water building up in his helmet.
During his time on the ISS, he became the first person to complete a spacewalk while sporting a Union flag on his shoulder. Pictured, prior to his spacewalk, January 14, 2016
Nearly a decade later, Major Peake reflects on the experience as 'very surreal' and difficult to put into words'.
'The feeling is a mixture of appreciating how remote and isolated our planet is,' he told MailOnline.
'I hesitate to use the word fragile because actually the planet's pretty robust – it's survived 4 billion years; it's got another 4 billion to go before the sun will cause its demise.
'But what you appreciate from space is not necessarily its fragility but its remoteness and the level of isolation against this vast black backdrop of the universe.
'And it strikes you that that is home – that's the only planet we've got to live on.
'On the one hand it makes you feel fairly small and insignificant but on the other hand it does make you appreciate that we are incredibly special.'
Major Peake spoke to MailOnline ahead of this summer's Goodwood Festival of Speed near his native Chichester where he's ambassador of the Future Lab exhibition showcasing the technologies of tomorrow.
He's already given the biggest indication yet that he's about to make a spectacular return into orbit after nearly a decade back on Earth.
Last year, he was confirmed as 'strategic advisor' for a mission led by US firm Axiom Space to send an all-UK team into space for the first time.
The trip will certainly require a seasoned astronaut to act as 'commander' akin to the captain on a ship – with Major Peake the most obvious contender.
Although he couldn't confirm whether he would indeed be commander of the mission, he said going to space is still 'always of interest'.
'I'm an astronaut who's fit and able to fly to space and command a mission,' he told MailOnline. 'So absolutely I'm willing and ready to command the mission and fly to space.'
Meet the astronauts tipped to fly into space as part of the all-UK mission with Tim Peake
Three Britons – including the world's first ever 'parastronaut' – are among the European Space Agency's first new cohort of astronauts in almost 15 years.
In November 2022, John McFall, Rosemary Coogan and Meganne Christian were named in a class of 17 men and women chosen from a whopping 22,523 applicants.
They will be hoping to follow in the footsteps of current British astronaut Tim Peake, who spent six months on the International Space Station (ISS) almost a decade ago.
Here's a closer look at the three adventurers, who may be joined by Major Peake himself on a trip to the ISS.
John McFall
Britain's John McFall was named as the world's first 'parastronaut' in November 2022
John McFall, 44, is a British father-of-three, surgical trainee and Paralympic medallist.
Originally from Frimley in Surrey, Mr McFall had his right leg amputated following a motorcycle accident in Thailand in 2000.
He was fitted with a prosthesis and is now working with the European Space Agency (ESA) to investigate how such a disability could affect a stint in space.
He won a bronze medal at the 2008 Paralympic Games in Beijing among other honours, before retiring to take up his medical studies at Cardiff University.
He has put his medical career on hold to work with ESA and follow his 'passion for science and life'.
Rosemary Coogan
Rosemary Coogan, 33, is an astrophysicist originally from Belfast in Northern Ireland.
She attended school in Brighton and gained two master's degrees from the University of Durham.
One of these focused on physics, mathematics, computer programming and astronomy, and the other on gamma-ray emission from black holes.
Coogan moved to the University of Sussex as a doctoral researcher, studying galaxy evolution and the activity of active galactic nuclei.
From a young age, she spent several weeks a year away from home onboard military training vessels and land bases as a Cadet Petty Officer with the Sea Cadets from 2002 to 2009.
Meganne Christian
Meganne Christian, 37, is a materials scientist graduate from the University of New South Wales in Sydney.
She was born in Pembury in Kent but moved to Australia at a young age and attended Illawarra Grammar School in Wollongong.
She said she was inspired to become an astronaut when one visited her school.
The materials scientist has worked at the National Research Council of Italy in Bologna and as a researcher at Concordia Station in Antarctica, one of the most remote places on Earth.
According to ESA, Meganne received several national awards for outstanding research in the field of engineering and industrial chemistry.

Frogs in boiling water: Creep of extreme heat events
A late 19th Century experiment was said to show a frog would not jump out of a pan of water and save itself if the water was heated slowly. A grisly way to scientists, like University of Reading's Eugene Mohareb, think the story could also be used to describe our failure to react to the high temperatures we are seeing."Extreme heat events have been creeping up on us over the past 25 years," he said. "Like with the frog and boiling water, we haven't noticed how much more frequent they've become."Statistics show that June heatwaves are becoming increasingly common and intense, so how can we keep the heat out of - as well as in - our homes? As strange as it may seem, one of the answers is the insulation we put into our homes to keep them warm in the experts say insulation in the walls can also act as a heat barrier. Staff at Swindon's National Self Build and Renovation Centre say they are seeing a big increase in calls from self-builders wanting to know how it works. Managing director Harvey Fremlin said: "The key is in the detail with insulation. "The fabric of your building will be breathable so it will retain the heat in the colder months, with the installation products designed to do that, but they're also designed to block out solar gain - the heating from the sun." The government has said 1.5 million hew homes need to be built over the next four years. It wants developers to install heat pumps in these homes to keep people warm while reducing carbon the right type of air source heat pump, installed correctly, can also help cool our buildings. Mr Fremlin said mechanical and heat recovery systems filter out the external air and "bring that fresh air into a home, providing heating in the winter and cooling air in the summer". Upgrading double glazing to triple glazing can also help as the extra layer will reflect the sun's rays back into the atmosphere. None of these solutions are cheap but one product Mr Fremlin says is becoming increasingly affordable is electric shutters. A common feature on apartment blocks in countries like Spain, he expects the extreme heat the UK is seeing at the moment will inspire more people to buy them. Electric shutters are not the only things we're used to seeing when we holiday in southern Europe. Air conditioning is one of the first things people look for when booking a holiday there. Dr Mohareb, who lectures in sustainable urban systems, does not think that is the answer for the UK."While we do have the occasional extreme heat event, many days of the year we won't have any need for air conditioning," he said."When you've got very short intermittent heat events then the expense of it isn't really worth it." Heatwaves are particularly dangerous for older people with health problems but a new report from the UK Green Building Council warns climate change means some schools in London and the South can expect heatwave-like temperatures for 10 weeks a year in a 2C (36F) global warming for the here and now, research by Imperial College London estimates more than 550 people will have died as a result of the recent spell of persistent hot weather. In its latest three month outlook, the Met Office predicted this summer (1 June to 31 August) is twice as likely to be hotter than pressure is on to make sure our towns and cities can cope with what is coming down the track but Dr Mohareb says there is still time to react to what is happening around us.''Adaptation is kind of the next big thing that we need to be moving on," he said. "We really need to be making more effort to improve the quality of the built environment so we're better prepared for the extreme weather events we're expecting."

Parents warned to limit their children's screen time, as research finds youngsters glued to smartphones and tablets have smaller brains and lower IQs
Parents are being warned to limit children's screen time after a study found it could lead to them having smaller brains and lower intelligence. Scientists found children who watched television and used smartphones, tablets and computers had, on average, lower IQs and less intracranial volume (ICV) – a marker for brain size. In contrast, children who exercised in their spare time were likely to be more intelligent and had a larger brain volume, according to the research. The study used databases from across Europe that contained information from thousands of children on IQ, screen use and physical exercise. This was analysed to establish whether there was any link between leisure time habits, intelligence and ICV – the total space within the skull which is used as a proxy for the maximum size of the brain. Larger ICV has been linked to superior intelligence. The researchers, based in China, say their results provide further evidence that excessive screen time has a lifelong impact on children's brain development. 'These findings highlight the critical need to manage and regulate children's media use while also promoting increased physical activity,' they wrote in the journal Developmental Cognitive Neuroscience. The study comes as children's screen time use has rocketed in recent years. The average amount of time British children aged five to 15 spend on screens rose from nine hours a week in 2009 to 15 hours a week in 2018, according to a House of Commons education committee report from last year. While there can be benefits, including building friendships and improving learning, negative effects include online bullying, exposure to violence and pornography, lower levels of physical activity and eye strain. Sir Cary Cooper, a psychology professor at the University of Manchester, said: 'Children are using these devices and they are not learning social and non-verbal skills that we pick up from interacting, face-to-face, with other people.'

EXCLUSIVE Think you're hilarious but your siblings don't find you funny? Scientists discover that humour doesn't run in the family
They are the groanworthy one-liners and corny puns that make your toes curl, with 'Dad jokes' becoming a byword for the most cringe-making of them all. But if you are worried about following in your Dad's footsteps, don't panic as it's unlikely you'll inherit his humour. Experts have found that, unlike intelligence or eye colour, humour doesn't run in the family. In the first ever study to look at the influence of genes and the environment on comedic abilities, scientists asked a thousand twins to create funny captions for cartoons. By comparing a mix of both identical twins, who share 100 per cent of their DNA, and non-identical twins, who are like any biological siblings and share about 50 per cent of their DNA, their findings revealed there was no evidence that they inherited their humorous talents. If comedic ability was inherited, then the researchers would have expected to see stronger humour similarities between the identical twins compared to the non-identical twins. However, they discovered that across all twin pairs, individuals shared the same level of comedic ability, indicating humour is shaped by the environment rather than genetics. It could also help explain the rarity of comedy duos from the same family - such as the Chuckle Brothers or the Marx Brothers - compared to actors, musicians or writers. Dr Gil Greengross, from the Psychology Department at Aberystwyth University, led the study, published in the journal Twin Research and Human Genetics. He said: 'Despite humour's importance, relatively little is known about how we develop our sense of humour or why one sibling can be funny and another cannot. 'Our study's finding that these talents are not inherited is surprising, as it contradicts most research on the heritability of cognitive abilities such as creativity and mathematical skills. So, it is really fascinating.' He explained that while telling a joke may seem simple, having a good sense of humour is a complex and unique trait that is influenced by a range of psychological attributes and personality characteristics. 'It varies across different social contexts, like when going on a date or entertaining,' he said. 'This may explain why, Chuckle and Marx Brothers aside, there are few successful comedians from the same immediate family. 'What is exciting about this research is it begs the question: if our sense of humour is not handed down from our parents but comes from our environment, what is it precisely that makes us funny?' The findings also have implications for how scientists think about humour's role in evolution and even dating. Dr Greengross added: 'These early findings also challenge the widely accepted evolutionary basis of humour. 'A great sense of humour can help ease tension in dangerous situations, foster cooperation, break down interpersonal barriers, and attract mates—all of which enhance survival and reproduction. 'There are also intriguing dating and mating aspects to this. Previous research has shown that women prioritise comedic talents in a partner more than do men, whereas men value a women's ability to appreciate their humour. 'Men experience stronger selection pressure to be funny to impress women, leading to men having slightly higher humour ability, on average — a finding supported by our study.'
