can you give me an example of this region found outer space?
A massive one has been found in the center of galaxy Messier 87 to name one.
Black hole
The Event Horizon Telescope (EHT), is an active program that directly observes the immediate environment of the event horizon of black holes, such as the black hole at the centre of the Milky Way. In April 2017, EHT began observation of the black hole in the center of Messier 87. 
who predicated that black holes emit radiation and what it is called Stephen Hawking what is this black hole all about? It  is a region of spacetime where gravity is so strong that nothing, no particles or even electromagnetic radiation such as light can escape from it.

Black hole [SEP] Observational evidence
The Event Horizon Telescope (EHT), is an active program that directly observes the immediate environment of the event horizon of black holes, such as the black hole at the centre of the Milky Way. In April 2017, EHT began observation of the black hole in the center of Messier 87. "In all, eight radio observatories on six mountains and four continents observed the galaxy in Virgo on and off for 10 days in April 2017" to provide the data yielding the image two years later in April 2019. After two years of data processing, EHT released the first direct image of a black hole, specifically the supermassive black hole that lies in the center of the aforementioned galaxy.
