A haunting audio recording released by the European Space Agency on Tuesday reveals what the Earth's magnetic field “sounds” like.
The magnetic field protects life from cosmic radiation and charged particles carried by powerful winds flowing from the Sun, according to a report by the ESA.
It is not something that humans can see or hear.
In recent years, scientists at the Technical University of Denmark have taken magnetic signals measured by ESA’s Swarm satellite mission and converted them into sound, the report said.
The results are spooky. The five-minute audio includes crackling sounds and what sounds like deep breathing.
“The team used these magnetic signals to manipulate and control a sonic representation of the core field,” musician and project supporter Klaus Nielsen from the Technical University of Denmark said in the report.
“The project has certainly been a rewarding exercise in bringing art and science together.”
Although the recording may sound like someone's worst nightmare, it “represents the magnetic field generated by Earth’s core and its interaction with a solar storm,” said the report.
ESA said the audio is a way to remind people that “the magnetic field exists and although its rumble is a little unnerving, the existence of life on Earth is dependent on it.”
The project was launched in 2013 and its aim was to understand exactly how the magnetic field is generated by measuring precisely the magnetic signals that stem not only from Earth’s core, but the mantle and the oceans.
It will also improve understanding of weather in space, ESA said in the report.
The magnetic field is generated by an ocean of superheated, swirling liquid iron that makes up the outer core about 3000 kilometres beneath the Earth's surface, said ESA.
“Acting as a spinning conductor in a bicycle dynamo, it creates electrical currents, which in turn, generate our continuously changing electromagnetic field,” the report said.
If you go
The flights
There are direct flights from Dubai to Sofia with FlyDubai (www.flydubai.com) and Wizz Air (www.wizzair.com), from Dh1,164 and Dh822 return including taxes, respectively.
The trip
Plovdiv is 150km from Sofia, with an hourly bus service taking around 2 hours and costing $16 (Dh58). The Rhodopes can be reached from Sofia in between 2-4hours.
The trip was organised by Bulguides (www.bulguides.com), which organises guided trips throughout Bulgaria. Guiding, accommodation, food and transfers from Plovdiv to the mountains and back costs around 170 USD for a four-day, three-night trip.

Five famous companies founded by teens
There are numerous success stories of teen businesses that were created in college dorm rooms and other modest circumstances. Below are some of the most recognisable names in the industry:
- Facebook: Mark Zuckerberg and his friends started Facebook when he was a 19-year-old Harvard undergraduate.
- Dell: When Michael Dell was an undergraduate student at Texas University in 1984, he started upgrading computers for profit. He starting working full-time on his business when he was 19. Eventually, his company became the Dell Computer Corporation and then Dell Inc.
- Subway: Fred DeLuca opened the first Subway restaurant when he was 17. In 1965, Mr DeLuca needed extra money for college, so he decided to open his own business. Peter Buck, a family friend, lent him $1,000 and together, they opened Pete’s Super Submarines. A few years later, the company was rebranded and called Subway.
- Mashable: In 2005, Pete Cashmore created Mashable in Scotland when he was a teenager. The site was then a technology blog. Over the next few decades, Mr Cashmore has turned Mashable into a global media company.
- Oculus VR: Palmer Luckey founded Oculus VR in June 2012, when he was 19. In August that year, Oculus launched its Kickstarter campaign and raised more than $1 million in three days. Facebook bought Oculus for $2 billion two years later.
