Astronomers have found the fastest-growing black hole ever seen, and it's got a monster appetite

Source: CNN

Astronomers have found the fastest-growing black hole ever seen in the universe, and they're calling this one a monster with an appetite. It's growing so fast it can devour a mass the size of the sun every two days.

Researchers at Australian National University first discovered this supermassive black hole, also known as a quasar, when data from a telescope called the SkyMapper flagged it as an object of potential interest. Then they used data from the European Space Agency's Gaia satellite to determine how far away it was. They found that it took more than 12 billion years for the light from this massive black hole to reach Earth. It's the brightest quasar that can be seen in visual or ultraviolet light.

"The heat radiation from the matter falling into the black hole, which is the light we see, is a few thousand times brighter than our own Milky Way galaxy," Christian Wolf, the lead researcher on the university's team of astronomers, wrote in an email to CNN.

The discovery of this massive black hole calls the existing science about black holes into question. Black holes have a speed limit that determines how fast they grow, which is proportional to their mass.

3. Present Tense ...

I get a kick out of people who use the present tense when describing events that occurred 12 billion years ago.

4. How far forward of - or in back of

 

this post as you read it is present tense. We do have clocks and calendars, but how relevant are they beyond our solar system?

5. Wow!

And just how long does one think a black hole exists?

From before Hawking's theory that black holes do eventually evaporate, it was thought that black holes are forever. They still kind of are, being that w/ Hawking's theory, black holes evaporating, it takes billions and trillions of years to evaporate. I don't recall his specific theory at that time, but of course it was fascinating as usual.

Thanks for posting!
