Watch meteor blaze across sky and explode with 'sonic boom'
On Wednesday night, a bright orange light was seen shooting across the sky, and a loud bang was also heard.
People have reported seeing the meteor in Argyll and Bute as well as on the Isle of Lewis, Stirling, and Glasgow. Adrian Coll The object was seen by Adrian Coll while searching for his friend's missing dog at the roadside at Loch Long at Coulport Naval Base on Wednesday night.
Meteors are bits of rock that burn up when they enter the Earth's atmosphere, creating streaking light across the sky.
Hundreds of Scots took to social media to share pictures of the bright light, with some reporting hearing a loud bang they assumed was an 'earthquake'. Adrian Coll The object was seen by Adrian Coll at Loch Long at Coulport Naval Base.
STV meteorologist Sean Batty said for a bang to be heard, the meteor was probably a piece of space rock bigger than a golf ball.
Dr Cyrielle Opitom from the University of Edinburgh's Institute for Astronomy said the meteor looked 'fairly big' in nature. Norma Macleod The object, thought to be a meteor, was caught by Norma Macleod's CCTV on Wednesday night.

While meteors are not uncommon in Scotland, Dr Opitom said this one looks 'quite special' because of how bright it burned.
'We don't know if there are any meteorites that have landed on the ground yet, but it would be really exciting as we could recover the rock from space and analyse it,' she told STV News. Adrian Coll The object, thought to be a meteor, left a trail that was still visible on Thursday morning.
'All over Scotland and the UK, there are cameras from the Fireball Network, so I'm sure footage analysis is well under way. If there are meteorites, we can find them and work back their trajectory.'
For a light streak and a bang (sonic boom), it's probably been a piece of space rock that was bigger than a golf ball.
These bits of rock, which drift around space pepper planets occasionally when drawn in by their gravitational pull, but luckily, Earth has a protective layer (the atmosphere), which means many of these small rocks burn up and disintegrate on entry.
However, sometimes the bigger ones, say bigger than a bowling ball, will burn up on entry, but because of it's size, some of it will survive the journey and reach the ground.
With this one spotted last night, it's difficult to say exactly how big it may have been and whether any of it survived to reach the ground. The only way of knowing would be if someone found a piece, although it may have fallen into the sea.
The big boom is the sonic boom created because of the speed the meteor enters the atmosphere. It's travelling at speeds way over the speed of sound, compressing the air and creating the boom we hear as it enters the atmosphere. It's the same sound we used to hear when Concorde entered the speed of sound as it headed out over the Atlantic.
These sonic booms can sometimes be so intense that windows can shatter, although there have been no reports of that, so it's possible the most intense boom has been over the sea.
There was a meteor in 2013 over Russia, which was estimated to be around 20 metres in size which created such a massive shock wave that thousands of buildings were damaged.
A great spectacle for those who spotted it, but also thankfully, by the looks of it, something small enough to just put on a bit of a show. Larger meteors are the ones to worry about, which could cause immense damage were they to hit Earth, but the good news is most of the bigger ones are monitored and tracked, although occasionally one can pop up which has been hidden.

Rising seas could put Easter Island's moai at risk by 2080, study warns
By the end of the century, rising sea levels could push powerful seasonal waves into Easter Island's 15 iconic moai statues, according to a new study published in the Journal of Cultural Heritage. About 50 other cultural sites in the area are also at risk from flooding. 'Sea level rise is real,' said Noah Paoa, lead author of the study and a doctoral student at the University of Hawaii at Manoa's School of Ocean and Earth Science and Technology. 'It's not a distant threat.' Paoa, who is from Easter Island — known to its Indigenous people as Rapa Nui — and his colleagues built a high-resolution 'digital twin' of the island's eastern coastline and ran computer models to simulate future wave impacts under various sea level rise scenarios. They then overlaid the results with maps of cultural sites to pinpoint which places could be inundated in the coming decades. The findings show waves could reach Ahu Tongariki, the largest ceremonial platform on the island, as early as 2080. The site, home to the 15 towering moai, draws tens of thousands of visitors each year and is a cornerstone of the island's tourism economy. Beyond its economic value, the ahu is deeply woven into Rapa Nui's cultural identity. It lies within Rapa Nui National Park, which encompasses much of the island and is recognized as a UNESCO World Heritage site. The roughly 900 moai statues across the island were built by the Rapa Nui people between the 10th and 16th centuries to honor important ancestors and chiefs. The threat isn't unprecedented. In 1960, the largest earthquake ever recorded — a magnitude 9.5 off the coast of Chile — sent a tsunami surging across the Pacific. It struck Rapa Nui and swept the already-toppled moai further inland, which damaged some of their features. The monument was restored in the 1990s. While the study focuses on Rapa Nui, its conclusions echo a wider reality: cultural heritage sites worldwide are increasingly endangered by rising seas. A UNESCO report published last month found that about 50 World Heritage sites are highly exposed to coastal flooding. A UNESCO spokesperson said that relevant experts weren't immediately available for comment. Possible defenses for Ahu Tongariki range from armoring the coastline and building breakwaters to relocating the monuments. Paoa hopes that the findings will bring these conversations about now, rather than after irreversible damage. 'It's best to look ahead and be proactive instead of reactive to the potential threats,' he said. ___ Follow Annika Hammerschlag on Instagram: @ahammergram ___ The Associated Press receives support from the Walton Family Foundation for coverage of water and environmental policy.

Scientists want to send tiny, solar-powered spacecraft to Mars
Scientists want to send tiny, solar-powered spacecraft to examine difficult-to-reach parts of Earth 's atmosphere – and eventually other planets too. The small devices are able to float in the air and could carry sensing instruments to monitor our climate as well as explore Mars, the researchers behind them suggest. Unlike conventional spacecraft, they do not need fuel to stay floating in the atmosphere. Instead, they use energy from light, through a process known as photophoresis that has been used to make objects levitate for 150 years. Despite that long history, the practical use of photophoresis has been limited to truly tiny objects or very powerful artificial light, and practical devices have not worked out. Now, however, researchers believe that they have made a centimetre-long flying device out of perforated sheets that can use natural sunlight to stay afloat. The flying structure is made from two thin, perforated membranes that are attached together by tiny supports. They can be used to create a tiny disc that is then able to leveitate. They could be sent up to the upper layers of the Earth's atmosphere. If they can be scaled up slightly, they would be able to carry antennae and circuits that would allow them to be used to monitor the atmosphere and for other science work. Eventually, the same design could be taken to other planets, they suggest. It is currently almost prohibitively expensive to send satellites to Mars, for instance – but doing so with the tiny spacecraft could allow researchers to monitor conditions on that planet, they say. 'If the full potential of this technology can be realized, swarms or arrays of such photophoretic flyers could be collecting high-resolution data on the temperature, pressure, chemical composition and wind dynamics of the mesosphere within the next decade,' Igor Bargatin from Penn University wrote in an article accompanying the new research.

Cats develop dementia in a similar way to humans
Cats develop dementia in a similar way to humans with Alzheimer's disease, leading to hopes of a breakthrough in research, according to scientists. Experts at the University of Edinburgh carried out a post-mortem brain examination on 25 cats which had symptoms of dementia in life, including confusion, sleep disruption and an increase in vocalisation. They found a build-up of amyloid-beta, a toxic protein and one of the defining features of Alzheimer's disease. The discovery has been hailed as a "perfect natural model for Alzheimer's" by scientists who believe it will help them explore new treatments for humans. Dr Robert McGeachan, study lead from the University of Edinburgh's Royal (Dick) School of Veterinary Studies, said: "Dementia is a devastating disease - whether it affects humans, cats, or dogs. "Our findings highlight the striking similarities between feline dementia and Alzheimer's disease in people. "This opens the door to exploring whether promising new treatments for human Alzheimer's disease could also help our ageing pets. Microscopy images of older cats which had previously shown symptoms of feline dementia revealed a build-up of amyloid-beta within the synapses - the junctions of brain cells. Synapses allow the flow of messages between brain cells, and losing these causes reduced memory and thinking abilities in humans with Alzheimer's. The team believe the discovery in cats could help them get a clearer understanding of the process, offering a valuable model for studying dementia in people. Previously, researchers have studied genetically-modified rodents, although the species does not naturally suffer from dementia. "Because cats naturally develop these brain changes, they may also offer a more accurate model of the disease than traditional laboratory animals, ultimately benefiting both species and their caregivers," Dr McGeachan said. Will this research benefit cats? The researchers found evidence that brain support cells - called astrocytes and microglia - engulfed the affected synapses. It's known as synaptic pruning, an important process during brain development but which contributes to dementia. Prof Danielle Gunn-Moore, an expert in feline medicine at the vet school, said the discovery could also help to understand and manage feline dementia. "Feline dementia is so distressing for the cat and for its person," she said. "It is by undertaking studies like this that we will understand how best to treat them. This will be wonderful for the cats, their owners, people with Alzheimer's and their loved ones." The animal rights campaign group People for the Ethical Treatment of Animals said the study appeared to have been conducted in a "respectful, non-invasive way" on the brain of cats that already died. However it said it would oppose any research that involved future experiments on live cats. The study, funded by Wellcome and the UK Dementia Research Institute, is published in the European Journal of Neuroscience, and included scientists from the Universities of Edinburgh and California, UK Dementia Research Institute and Scottish Brain Sciences.
