Astronomers have captured a new image of a powerful jet emerging from the M87 galaxy’s supermassive black hole.
The observations have revealed that the jet of energy can travel trillions of kilometres once spewed from the black hole and the helix-like structure of the jet.
A high-resolution image, captured by the Karl G Jansky Very Large Array, a powerful radio astronomy observatory in New Mexico, shows that the jet has a corkscrew-shaped structure.
Astronomers have learnt that the galactic jet stretched almost 3,300 light years from the galaxy’s supermassive black hole.
It is the farthest distance a magnetic field has been detected in a jet.
The findings were published in The Astrophysical Journal Letters.
“By making high-quality VLA images at several different radio wavelengths of the galaxy Messier 87 (M87), we were able to reveal the 3-dimensional structure of the magnetic field in this jet for the first time,” Alice Pasetto, of the National Autonomous University of Mexico, said.
“The material in this jet traces a double helix, similar to the structure of DNA.”
Supermassive black holes are the largest type and have millions to billions of times the mass of the Sun.
Their gravitation pull is so strong that they destroy all nearby matter, including gas and dust.
But some surrounding particles escape moments before capture and are blown violently into space, creating jets.
The jet was emitted from the first black hole ever to be imaged. Detected 55 million light years away from Earth, its discovery was used to confirm Albert Einstein’s theory of relativity.
“M87 is relatively near to us and its jet is very powerful, making it an excellent target for study. The clues it gives us can help us understand this very important and ubiquitous phenomenon in the universe,” Jose L Gomez, a co-author of the study, said.
Researchers behind the study used the telescope to reveal details of the magnetic field by tracing the alignment of radio waves emitted from it.
They also measured the magnetic field’s strength across different parts of the jet, helping create the highest resolution and detailed images of the galaxy’s jet.
“Helical magnetic fields are expected close to the black hole, and are thought to play a highly important role in channelling the material into a narrow jet, but we didn’t expect to find such a strong helical field extending so far outward,” Jose M Marti, another co-author of the study, said.
The findings will help astronomers deepen their understanding of black holes and their jets.
For decades, they have been trying to solve the mysteries of the space objects and how they occur.
In July, the Event Horizon Telescope, consisting of eight radio observatories that act as one Earth-sized telescope, caught an enormous jet escaping from a black hole in the centre of the Centaurus A galaxy.

Fast facts on Neil Armstrong’s personal life:
- Armstrong was born on August 5, 1930, in Wapakoneta, Ohio
- He earned his private pilot’s license when he was 16 – he could fly before he could drive
- There was tragedy in his married life: Neil and Janet Armstrong’s daughter Karen died at the age of two in 1962 after suffering a brain tumour. She was the couple’s only daughter. Their two sons, Rick and Mark, consulted on the film
- After Armstrong departed Nasa, he bought a farm in the town of Lebanon, Ohio, in 1971 – its airstrip allowed him to tap back into his love of flying
- In 1994, Janet divorced Neil after 38 years of marriage. Two years earlier, Neil met Carol Knight, who became his second wife in 1994

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Safety 'top priority' for rival hyperloop company
The chief operating officer of Hyperloop Transportation Technologies, Andres de Leon, said his company's hyperloop technology is “ready” and safe.
He said the company prioritised safety throughout its development and, last year, Munich Re, one of the world's largest reinsurance companies, announced it was ready to insure their technology.
“Our levitation, propulsion, and vacuum technology have all been developed [...] over several decades and have been deployed and tested at full scale,” he said in a statement to The National.
“Only once the system has been certified and approved will it move people,” he said.
HyperloopTT has begun designing and engineering processes for its Abu Dhabi projects and hopes to break ground soon.
With no delivery date yet announced, Mr de Leon said timelines had to be considered carefully, as government approval, permits, and regulations could create necessary delays.

Who has been sanctioned?
Daniella Weiss and Nachala
Described as 'the grandmother of the settler movement', she has encouraged the expansion of settlements for decades. The 79 year old leads radical settler movement Nachala, whose aim is for Israel to annex Gaza and the occupied West Bank, where it helps settlers built outposts.
Harel Libi & Libi Construction and Infrastructure
Libi has been involved in threatening and perpetuating acts of aggression and violence against Palestinians. His firm has provided logistical and financial support for the establishment of illegal outposts.
Zohar Sabah
Runs a settler outpost named Zohar’s Farm and has previously faced charges of violence against Palestinians. He was indicted by Israel’s State Attorney’s Office in September for allegedly participating in a violent attack against Palestinians and activists in the West Bank village of Muarrajat.
Coco’s Farm and Neria’s Farm
These are illegal outposts in the West Bank, which are at the vanguard of the settler movement. According to the UK, they are associated with people who have been involved in enabling, inciting, promoting or providing support for activities that amount to “serious abuse”.
