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.

Watch: Mysterious interstellar object passes through our solar system
A mysterious interstellar object, named 3I/ATLAS, has been observed travelling through our solar system. Images from the Canary Islands Institute of Physics captured the object, which Nasa has confirmed is only the third interstellar object ever seen. Nasa said that 3I/ATLAS will pass Earth at a distance of approximately 150 million miles, posing no threat to the planet. The object is expected to be visible to ground-based telescopes through September, reappearing in early December for its closest approach to Earth. Watch the video in full above.

Mystery 12-mile-wide ‘fuzzy object with a tail' spotted blazing through our solar system at 37 miles a SECOND, Nasa says
A MYSTERIOUS cosmic object has been spotted zooming through our solar system - and astronomers say it is only the third of its kind. The "fuzzy" object with a "short tail" is no fur-ball alien, but instead a large icy comet from interstellar space. 6 6 6 6 The celestial visitor is only the third interstellar object on record to grace our solar system, and is also likely the largest yet detected. It follows the rare visits from the famous 1I/ʻOumuamua asteroid in 2017 and 2I/Borisov in 2019. "The fact that we see some fuzziness suggests that it is mostly ice rather than mostly rock," Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, told AFP. Peter Veres, an astronomer with the International Astronomical Union's Minor Planet Center, which was responsible for the official confirmation, added: "It looks kind of fuzzy... It seems that there is some gas around it, and I think one or two telescopes reported a very short tail." The 12-mile-wide comet, known originally as A11pl3Z before it was confirmed to be of interstellar origin, is blazing through the solar system at great speed. While astronomers are still refining their calculations, the object appears to be zooming more than 60 kilometers (37 miles) a second. 6 The comet poses no threat to Earth, said Richard Moissl, head of planetary defense at the European Space Agency (ESA). It's closest approach of Earth, which is projected to occur in late October, will see it pass "just inside the orbit of Mars," according to Moissl. It will pass our blue dot no closer than 240 million kilometres – over 1.5 times the distance between Earth and the Sun. By the time it does make its closest path of Earth, it will be hidden by the Sun - meaning stargazers will have no chance of spotting it in the night sky. Incredible moment a fireball comet is spotted racing past stunning aurora towards Earth While it is expected to reappear by early December, this will only offer astronomers another window for study. The comet was first spotted on 1 July by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Río Hurtado, Chile. Its unusual trajectory immediately raised suspicions that the comet came from an unknown world in interstellar space. Its current path "means it's not orbiting our star, but coming from interstellar space and flying off to there again," according to Moissl. What's the difference between an asteroid, meteor and comet? Here's what you need to know, according to Nasa... Asteroid: An asteroid is a small rocky body that orbits the Sun. Most are found in the asteroid belt (between Mars and Jupiter) but they can be found anywhere (including in a path that can impact Earth) Meteoroid: When two asteroids hit each other, the small chunks that break off are called meteoroids Meteor: If a meteoroid enters the Earth's atmosphere, it begins to vapourise and then becomes a meteor. On Earth, it'll look like a streak of light in the sky, because the rock is burning up Meteorite: If a meteoroid doesn't vapourise completely and survives the trip through Earth's atmosphere, it can land on the Earth. At that point, it becomes a meteorite Comet: Like asteroids, a comet orbits the Sun. However rather than being made mostly of rock, a comet contains lots of ice and gas, which can result in amazing tails forming behind them (thanks to the ice and dust vaporizing) ESA's Planetary Defence Office, tasked with safeguarding Earth from potential asteroid and comet impacts, alerted astronomers who can now track the comet's path. These efforts are part of ESA's broader mission to detect, track, and characterise near-Earth objects. "What makes interstellar objects like 3I/ATLAS so extraordinary is their absolutely foreign nature," ESA wrote in a recent blog post. "They are remnants of other planetary systems, carrying with them clues about the formation of worlds far beyond our own. "It may be thousands of years until humans visit a planet in another solar system and interstellar comets offer the tantalising opportunity for us to touch something truly otherworldly." That's why the space agency is preparing the Comet Interceptor mission for 2029. ESA is set to send a spacecraft into a parking orbit in space to wait for a suitable target comet – or even a rare interstellar object - to retrieve samples from. 6

Experts predict weeks of rare meteor showers after stunning display – here's how Scots can see them
SCOTS were in total awe on Wednesday night as they saw a bright orange light soaring across the sky. The mysterious object was spotted across the Central Belt, with people from Glasgow to Edinburgh all reporting their sightings. 5 The meteor was spotted over Scotland Credit: Edinburgh Airport 5 The bright orange light was seen soaring across the skies on Wednesday night Credit: Edinburgh Airport 5 Experts revealed there will be more chances to see it this month Credit: Edinburgh Airport 5 Locals were baffled after spotting the bright light soaring through the sky Credit: Edinburgh Airport It raced across the night sky leaving a bright amber tail in its wake. Edinburgh Airport even shared images from their security cameras of the meteor soaring over the skies. And experts were quick to confirm what they had all seen was a meteor. Meteors are small pieces of interplanetary debris which enter the earths atmosphere and burn up. But if anyone didn't get a glance and is feeling some cosmic FOMO then they don't need to worry. The meteor everyone saw on Wednesday was part of the Alpha Capricornids, and they will be seen again this month. The gathering of galactic debris soars through space and is visible when it hits the atmosphere during the summer months. It is known for producing slow-moving and very bright fireballs as they hit earth's atmosphere and burn up. Their spotting season normally begins on July 3, the day when most people saw the first sighting. This year's season is expected to end on August 15 but there is one day when the season will peak around July 30. Incredible moment a fireball comet is spotted racing past stunning aurora towards Earth Experts have now revealed the best way for anyone to get out and try to see them. Royal Observatory Greenwich astronomer Jessica Lee said: "This meteor shower is known for producing fireballs. "Fireballs are exceptionally bright meteors, normally caused by larger sized fragments of the parent comet. "This shower is linked with debris from a comet called 169P/NEAT. Mostly the objects causing fireballs still burn up in our atmosphere and don't reach the surface, but it is possible that parts survive. "Fireballs are exciting to witness but not incredibly rare - it's just that most of the approximately 50 tons of material that fall through the Earth's atmosphere each day do so over the sea or over less populated areas." How to see a meteor shower? IF you want to get a glimpse of the meteor showers flying over Scotland's skies, then experts have combined these top tips to make sure you don't miss out. Plan ahead - Make sure you check the weather before you go. Severe or harsh weather isn't ideal for meteor spotting so try and find somewhere with calmer conditions if you can. Make sure you check the weather before you go. Severe or harsh weather isn't ideal for meteor spotting so try and find somewhere with calmer conditions if you can. Save the date - If you cannot find the right conditions on the peak of the storm then try heading out on some of the days before. You are much more likely to see a storm on the days leading up to the peak than the days after. If you cannot find the right conditions on the peak of the storm then try heading out on some of the days before. You are much more likely to see a storm on the days leading up to the peak than the days after. Find somewhere dark - Try to reduce the amount of light around you. This could mean heading out to the countryside, a nearby park or even turning your back to street lamps if you're not able to go anywhere. Try to reduce the amount of light around you. This could mean heading out to the countryside, a nearby park or even turning your back to street lamps if you're not able to go anywhere. Let your eyes adjust - Give your eyes at least 15 minutes to adjust to the dark conditions. This means you could be able to spot more faint meteors .

You can always check your messages when you tell people about the meteors you saw. Letting your eyes adjust means staying off your phone. The light from the screen will stop your eyes from adjusting. You can always check your messages when you tell people about the meteors you saw. More sky the better - Meteors can appear in any part of the sky so the more of the sky you can see, the better. Find an area with a clear view of the horizon away from trees and buildings. Meteors can appear in any part of the sky so the more of the sky you can see, the better. Find an area with a clear view of the horizon away from trees and buildings. Use your eyes - Binoculars and telescopes are not necessary as they will restrict the size of the sky that will be visible to you. Binoculars and telescopes are not necessary as they will restrict the size of the sky that will be visible to you. Use an app - If you aren't sure about where you should go to see a meteor shower, try using a stargazing app to find the perfect spot. She added: "The Alpha Capricornids meteor shower is active between the July 3 and August 15. "The peak of this shower will be on the 30th July, but don't expect hundreds of shooting stars, as it has a maximum of around 5 meteors per hour. "If you do want to try and catch a shooting star you'll need to go outside when it's dark and clear, and ideally somewhere with a clear view of as much of the sky as possible. "Meteor showers are always a waiting game, so bring a hot drink, something comfortable to sit on and wrap up warm if needed!" Not only will Scots be able to see the Alpha Capricornids, but it will overlap with the Perseids, one of the most dramatic and highly anticipated meteor events of the year. The Perseids will be visible from July 17 until August 24. If conditions are ideal then stargazers could see up to 150 bright fast moving meteors flying through the sky every hour. Scottish skywatchers were also treated to the Lyrid meteor shower in April and the Quadrantid meteor shower in January.
