First ever black hole image released.

Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy. It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster".

The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world It was captured by the Event Horizon Telescope (EHT), a network of eight linked telescopes. 

Prof Heino Falcke, of Radboud University in the Netherlands, who proposed the experiment, told BBC News that the black hole was found in a galaxy called M87.

"What we see is larger than the size of our entire Solar System," he said.

"It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute monster, the heavyweight champion of black holes in the Universe."

The image shows an intensely bright "ring of fire", as Prof Falcke describes it, surrounding a perfectly circular dark hole. The bright halo is caused by superheated gas falling into the hole. The light is brighter than all the billions of other stars in the galaxy combined - which is why it can be seen at such distance from Earth.

The edge of the dark circle at the centre is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull, not even light can escape.

The image matches what theoretical physicists and indeed, Hollywood directors, imagined black holes would look like, according to Dr Ziri Younsi, of University College London - who is part of the EHT collaboration.

"Although they are relatively simple objects, black holes raise some of the most complex questions about the nature of space and time, and ultimately of our existence," he said.

"It is remarkable that the image we observe is so similar to that which we obtain from our theoretical calculations. So far, it looks like Einstein is correct once again."

But having the first image will enable researchers to learn more about these mysterious objects. They will be keen to look out for ways in which the black hole departs from what's expected in physics. No-one really knows how the bright ring around the hole is created. Even more intriguing is the question of what happens when an object falls into a black hole.

Mozambique Cyclone: “Almost everything is destroyed.”



People carry their personal effects through a flooded section of Praia Nova in Beira after the cyclone. Tropical Cyclone Idai destroyed and damaged homes and knocked out electricity and communications.


Cyclone Idai hit the city of Beira hard and the scale of damage is massive, say Red Cross and Red Crescent aid workers who reached the Mozambican city a few days ago. The scale of devastation is enormous. It seems that 90 per cent of the area is completely destroyed.”

The Red Cross and Red Crescent team was among the first to arrive in Beira since Cyclone Idai made landfall March 14-15. With Beira’s airport closed and roads cut off due to flooding, the team drove from Maputo, the capital city, before taking a helicopter for the last leg of the journey. “Almost everything is destroyed. Communication lines have been completely cut and roads have

been destroyed. Some affected communities are not accessible,” said LeSueur. “Beira has been severely battered. But we are also hearing that the situation outside the city could be even worse. Yesterday, a large dam burst and cut off the last road to the city.”

While the physical impact of Idai is beginning to emerge, the human impact is still unclear. Authorities in the country are warning that the death toll may climb beyond 1,000 people.

Heavy rain will continue in the coming days which may only exacerbate the dire situation and cause already saturated rivers to overflow.

Following its landfall in Mozambique, the cyclone continued west to Zimbabwe as a tropical storm, wreaking havoc in the eastern part of the country, with Manicaland Province being the hardest-hit. At least 31 deaths have been reported and over 100 people are missing in Zimbabwe.
