Scientists have revealed the world’s first photograph of a black hole, one of the star and light-swallowing monsters scattered throughout our universe and usually blocked to our vision by shields of gravity*.

The image of a dark centre surrounded by a flame-orange halo of white-hot plasma* looks like any number of artists’ drawings over the past 30 years.

 

“We have seen what we thought was unseeable. We have seen and taken a picture of a black hole,” said Sheperd Doeleman, Event Project Horizon project director at Harvard University. “This is an extraordinary scientific feat* accomplished by a team of more than 200 researchers,”  he said.

 

Carlos Moedas, European Commissioner for Research, Science and Innovation described capturing the photograph as a “huge breakthrough for humanity*”.

The term “black hole”, which was created in the mid-60s by US physicist* John Archibald Wheeler, refers to a point in space where matter is so dense as to create a gravity field from which nothing can escape.

That means stars, planets, gas, dust, all forms of electromagnetic radiation* and light are all sucked into the black hole forever.

 

The supermassive black hole captured by this team using a far-away network of radio telescopes is 50 million light years* from Earth at the centre of a galaxy known as M87.

“It’s a distance that we could have barely imagined,” Frederic Gueth, an astronomer* at France’s National Centre for Scientific Research and co-author of studies detailing the findings, said.

Capturing the image at such a distance is like snapping a photograph of a pebble on the Moon, the scientists said.

 

Black holes, which come in a variety of sizes, are extraordinarily dense entities formed when massive stars collapse at the end of their life cycle.


 

▪ Talk!! Talk!!

1.Are there billions of black holes in the universe?  Support your answer.

2.Do you think black holes really exist?

3.Why are people scared of black holes?

4.Do you believe that a black hole can take us to another dimension?

5.Do you there is a way out, in case an object enters a black hole?
