Astronomers found the fastest growing black hole outside the Milky Way. They reported that the size of the supermassive black hole is comparable to 20 billion stars combined with a growth rate of 1
Astronomers have discovered the fastest growing black hole ever known in the Universe and capable of absorbing the matter equivalent every two days to the size of the sun.
This supermassive black hole is about 20 billion stars in size and continues to grow at the rate of 1 percent per million years. It emits light that is a thousand times brighter than an entire galaxy due to the heat and friction caused by all the gases it absorbs.
"If we had this monster in the middle of our Milky Way, it would appear ten times brighter than a full moon, and it would seem like an incredibly bright dot star that would wash out almost all the stars in the sky," Dr. Christian Wolf from the Research School of Astronomy and Astrophysics at the Australian National University in Canberra
The energy that comes from the quasar or black hole is mainly ultraviolet light and emitted X-rays. Experts say that the black hole exists in the Milky Way, life would be impossible on Earth.
The study was published on May 11 in the Publications of the Astronomical Society of Australia
Detecting The Massive Black Hole
Wolf's team discovered the black hole while using the SkyMapper Telescopes at the ANU Siding Spring Observatory in Coonabarabran, New South Wales, searched.
The light detected with SkyMapper has been confirmed by the Europeans
"While objects of this luminosity are extremely rare in the universe, they are particularly valuable as bright background and reference sources to study the properties of intervening matter along the line of sight, and for Over the next few decades, we will directly explore the expansion of our universe with new instruments, "the authors reported.
Although Wolf's team is uncertain, like the black hole during the first days of the universe, he said they are looking for similar giants.
What are black holes?
A black hole is an intense magnet that feeds everything on its way, including light. When gas and dust enter the void, the matter is rapidly accelerated and heated to very high temperatures. This then generates large amounts of X-ray light.
While it seems that black holes suck matter, the material does not necessarily fall into it. Rather, it is immediately swirled outward at the speed of light.
Black holes are divided into three groups: primordial, stellar, and supermassive. Scientists suspect that primeval black holes formed immediately after the Big Bang, while stellar black holes occur when a massive star collapses.
The supermassives, as discovered by Wolf's team, appeared simultaneously with the galaxies
