Astronomers have discovered the most distant black hole ever seen, located about 13.2 billion light years away from Earth.
The discovery of the celestial object, which is 10 to 100 million times the mass of the Sun, could help scientists understand how black holes became so large in the infancy of the universe.
Scientists used the James Webb Space Telescope to find the host galaxy and then the Chandra X-ray Observatory to detect the black hole.
Findings were published in the science journal Nature Astronomy, Nasa announced on Monday.
“Now, finally discovering a black hole that was so large, when the universe was so young, tells us that the black hole must have been very large when it was initially formed, probably from the direct collapse of a massive gas cloud,” said Andy Goulding, a research scientist at Princeton University who was part of the study.
Black holes are formed by the catastrophic collapse of a star, an event that compresses matter into such a relatively small space that nothing, not even light, can escape its gravitational pull.
Scientists have spent decades studying the space phenomenon, with the first image of a black hole taken in 2019 using powerful telescopes.
The most recently discovered black hole is located in the UHZ1 galaxy, which showed the presence of intense, superheated gas.
Astronomers were able to use the signs of large amounts of gas being emitted to detect the black hole.
“There are physical limits on how quickly black holes can grow once they’ve formed, but ones that are born more massive have a head start,” said Mr Goulding.
“It’s like planting a sapling, which takes less time to grow into a full-sized tree than if you started with only a seed.”
The James Webb Space Telescope played a crucial role in helping to find the galaxy that the black hole was located in.
It was launched on Christmas Day of 2021 to help scientists learn more about the formation of the universe.
The first image from the telescope was revealed by US President Joe Biden on July 11. It showed the galaxy cluster SMACS 0723 as it was 4.6 billion years ago.
Researchers have been using the telescope to learn more about the solar system and its planets.
Last year, released images showed the planet Jupiter in striking detail.
The planet, which is believed to have 79 moons, has a unique composition and inner structure that researchers want to further study.

Unresolved crisis
Russia and Ukraine have been locked in a bitter conflict since 2014, when Ukraine’s Kremlin-friendly president was ousted, Moscow annexed Crimea and then backed a separatist insurgency in the east.
Fighting between the Russia-backed rebels and Ukrainian forces has killed more than 14,000 people. In 2015, France and Germany helped broker a peace deal, known as the Minsk agreements, that ended large-scale hostilities but failed to bring a political settlement of the conflict.
The Kremlin has repeatedly accused Kiev of sabotaging the deal, and Ukrainian officials in recent weeks said that implementing it in full would hurt Ukraine.
The more serious side of specialty coffee
While the taste of beans and freshness of roast is paramount to the specialty coffee scene, so is sustainability and workers’ rights.
The bulk of genuine specialty coffee companies aim to improve on these elements in every stage of production via direct relationships with farmers. For instance, Mokha 1450 on Al Wasl Road strives to work predominantly with women-owned and -operated coffee organisations, including female farmers in the Sabree mountains of Yemen.
Because, as the boutique’s owner, Garfield Kerr, points out: “women represent over 90 per cent of the coffee value chain, but are woefully underrepresented in less than 10 per cent of ownership and management throughout the global coffee industry.”
One of the UAE’s largest suppliers of green (meaning not-yet-roasted) beans, Raw Coffee, is a founding member of the Partnership of Gender Equity, which aims to empower female coffee farmers and harvesters.
Also, globally, many companies have found the perfect way to recycle old coffee grounds: they create the perfect fertile soil in which to grow mushrooms.

How will Gen Alpha invest?
Mark Chahwan, co-founder and chief executive of robo-advisory firm Sarwa, forecasts that Generation Alpha (born between 2010 and 2024) will start investing in their teenage years and therefore benefit from compound interest.
“Technology and education should be the main drivers to make this happen, whether it’s investing in a few clicks or their schools/parents stepping up their personal finance education skills,” he adds.
Mr Chahwan says younger generations have a higher capacity to take on risk, but for some their appetite can be more cautious because they are investing for the first time. “Schools still do not teach personal finance and stock market investing, so a lot of the learning journey can feel daunting and intimidating,” he says.
He advises millennials to not always start with an aggressive portfolio even if they can afford to take risks. “We always advise to work your way up to your risk capacity, that way you experience volatility and get used to it. Given the higher risk capacity for the younger generations, stocks are a favourite,” says Mr Chahwan.
Highlighting the role technology has played in encouraging millennials and Gen Z to invest, he says: “They were often excluded, but with lower account minimums ... a customer with $1,000 [Dh3,672] in their account has their money working for them just as hard as the portfolio of a high get-worth individual.”
