    Astronomers Just Discovered a 'Supermassive' Black Hole. 

    'Hard to Comprehend How Big This Thing Is.'

    Astronomers say they have found one of the universe's largest black holes 

    to date using a new technique.

    Scientists at Durham University discovered the "ultramassive" black hole 

    by observing its pull on passing light, called gravitational lensing.

    Dr James Nightingale who led the study said even he struggled to "comprehend how big this thing is".

    Their findings have been published in the journal Monthly Notices of the Royal Astronomical Society.

    The academics said the black hole was 30 billion times the size of our Sun 

    and was the first to be measured using gravitational lensing.

    Dr Nightingale told BBC Radio Newcastle: 

    "Even as an astronomer, I find it hard to comprehend how big this thing is.

    "If you look at the night sky and count up all the stars and planets 

    you can see and put them in a single point, it would be a fraction of a percent the size of this black hole.

    "This black hole is bigger than the majority of galaxies in the universe."

    He said the discovery "pushes our understanding of astronomy to the limits", 

    adding: "How do you form a black hole this big in just 13 billions years of the universe's existence?"

    What is a black hole?

    A black hole is a region of space where matter has collapsed in on itself.

    The gravitational pull is so strong that nothing, not even light, can escape.

    Black holes will emerge from the explosive demise of certain large stars.

    But some are truly huge and are billions of times the mass of our Sun.

    How these monsters - found at galaxy centres - formed is unknown.

    But it is clear they energise the galaxy and will influence its evolution.

    is one of the biggest ever detected and on the upper limit of how large
