Scientists on Thursday provided the first look at the monster lurking at the centre of our Milky Way galaxy, in an image of a supermassive black hole that devours any matter wandering within its enormous gravitational pull.
Their image of Sagittarius A*, or SgrA*, is only the second ever taken of a black hole.
The feat was accomplished by the same Event Horizon Telescope international collaboration that in 2019 unveiled the first photo of a black hole, which is at the centre of a different galaxy.
Sagittarius A* has four million times the mass of our Sun and is about 26,000 light years from Earth. A light year is the distance light travels in a year, or 9.5 trillion kilometres.

Black holes are extraordinarily dense objects with gravity so strong that not even light can escape, which makes finding them challenging.
A black hole's event horizon is the point of no return beyond which anything — stars, planets, gas, dust and all forms of electromagnetic radiation — is dragged into oblivion.
Project scientists have looked for a ring of light around a region of darkness representing the black hole. It is super-heated disrupted matter and radiation circling at tremendous speed at the edge of the event horizon, and is known as the black hole's shadow or silhouette.
The Milky Way is a spiral galaxy that contains at least 100 billion stars. Viewed from above or below it resembles a spinning pinwheel, with our Sun on one of the arms and Sagittarius A* at the centre.
The image released in 2019 of the supermassive black hole in a galaxy called Messier 87, or M87, showed a glowing ring of red, yellow and white surrounding a dark centre.
The M87 black hole is far more distant and massive than Sagittarius A*. It is about 54 million light years from Earth and has a mass 6.5 billion times that of our Sun.
The researchers said that the image of Sagittarius A*, despite it being much closer to our solar system than M87, was harder to take.
The diameter of Sagittarius A* is about 17 times that of the sun, meaning it would be within the innermost planet Mercury's solar orbit. In contrast, M87's diametre would encompass the entirety of our solar system.
"Sagittarius A* is over 1,000 less massive than the black hole at M87," said radio astronomer Lindy Blackburn, an EHT data scientist at the Harvard-Smithsonian Centre for Astrophysics.
"But since it is in our own galaxy it is much closer, and should appear just slightly larger on the sky.
"However, the smaller physical size of Sgr A* also means that everything changes about a thousand times faster for Sgr A* than M87.
"We must also peer through the messy disc of our own galaxy to view Sgr A*, which blurs and distorts the image."
The Event Horizon Telescope is a global network of observatories collaborating to observe radio sources associated with black holes. The project was begun in 2012 to try to directly observe the immediate environment of a black hole.
There are different categories of black holes. The smallest are so-called stellar-mass black holes formed by the collapse of massive stars at the ends of their life cycles.
There also are intermediate-mass black holes, which have larger mass. And finally there are the supermassive black holes that inhabit the centre of most galaxies.
These are thought to arise relatively soon after their galaxies are formed, devouring enormous amounts of material to achieve colossal size.
Thursday's announcement was made simultaneously in the US, Germany, China, Mexico, Chile, Japan and Taiwan.

Quick pearls of wisdom
Focus on gratitude: And do so deeply, he says. “Think of one to three things a day that you’re grateful for. It needs to be specific, too, don’t just say ‘air.’ Really think about it. If you’re grateful for, say, what your parents have done for you, that will motivate you to do more for the world.”
Know how to fight: Shetty married his wife, Radhi, three years ago (he met her in a meditation class before he went off and became a monk). He says they’ve had to learn to respect each other’s “fighting styles” – he’s a talk it-out-immediately person, while she needs space to think. “When you’re having an argument, remember, it’s not you against each other. It’s both of you against the problem. When you win, they lose. If you’re on a team you have to win together.”
WHAT IS GRAPHENE?
It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were experimenting with sticky tape and graphite, the material used as lead in pencils.
Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But when they repeated the process many times, the flakes got thinner.
By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment led to graphene being isolated for the very first time.
In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics.
Soldier F
“I was in complete disgust at the fact that only one person was to be charged for Bloody Sunday.
“Somebody later said to me, 'you just watch - they'll drop the charge against him'. And sure enough, the charges against Soldier F would go on to be dropped.
“It's pretty hard to think that 50 years on, the State is still covering up for what happened on Bloody Sunday.”
Jimmy Duddy, nephew of John Johnson
Day 5, Abu Dhabi Test: At a glance
Moment of the day When Dilruwan Perera dismissed Yasir Shah to end Pakistan’s limp resistance, the Sri Lankans charged around the field with the fevered delirium of a side not used to winning. Trouble was, they had not. The delivery was deemed a no ball. Sri Lanka had a nervy wait, but it was merely a stay of execution for the beleaguered hosts.
Stat of the day – 5 Pakistan have lost all 10 wickets on the fifth day of a Test five times since the start of 2016. It is an alarming departure for a side who had apparently erased regular collapses from their resume. “The only thing I can say, it’s not a mitigating excuse at all, but that’s a young batting line up, obviously trying to find their way,” said Mickey Arthur, Pakistan’s coach.
The verdict Test matches in the UAE are known for speeding up on the last two days, but this was extreme. The first two innings of this Test took 11 sessions to complete. The remaining two were done in less than four. The nature of Pakistan’s capitulation at the end showed just how difficult the transition is going to be in the post Misbah-ul-Haq era.

Tomato and walnut salad
A lesson in simple, seasonal eating. Wedges of tomato, chunks of cucumber, thinly sliced red onion, coriander or parsley leaves, and perhaps some fresh dill are drizzled with a crushed walnut and garlic dressing. Do consider yourself warned: if you eat this salad in Georgia during the summer months, the tomatoes will be so ripe and flavourful that every tomato you eat from that day forth will taste lacklustre in comparison.
Badrijani nigvzit
A delicious vegetarian snack or starter. It consists of thinly sliced, fried then cooled aubergine smothered with a thick and creamy walnut sauce and folded or rolled. Take note, even though it seems like you should be able to pick these morsels up with your hands, they’re not as durable as they look. A knife and fork is the way to go.
Pkhali
This healthy little dish (a nice antidote to the khachapuri) is usually made with steamed then chopped cabbage, spinach, beetroot or green beans, combined with walnuts, garlic and herbs to make a vegetable pâté or paste. The mix is then often formed into rounds, chilled in the fridge and topped with pomegranate seeds before being served.

Explainer: Tanween Design Programme
Non-profit arts studio Tashkeel launched this annual initiative with the intention of supporting budding designers in the UAE. This year, three talents were chosen from hundreds of applicants to be a part of the sixth creative development programme. These are architect Abdulla Al Mulla, interior designer Lana El Samman and graphic designer Yara Habib.
The trio have been guided by experts from the industry over the course of nine months, as they developed their own products that merge their unique styles with traditional elements of Emirati design. This includes laboratory sessions, experimental and collaborative practice, investigation of new business models and evaluation.
It is led by British contemporary design project specialist Helen Voce and mentor Kevin Badni, and offers participants access to experts from across the world, including the likes of UK designer Gareth Neal and multidisciplinary designer and entrepreneur, Sheikh Salem Al Qassimi.
The final pieces are being revealed in a worldwide limited-edition release on the first day of Downtown Designs at Dubai Design Week 2019. Tashkeel will be at stand E31 at the exhibition.
Lisa Ball-Lechgar, deputy director of Tashkeel, said: “The diversity and calibre of the applicants this year … is reflective of the dynamic change that the UAE art and design industry is witnessing, with young creators resolute in making their bold design ideas a reality.”
