What Makes It Unusual? | इसकी विशेषता क्या है?
The object has been proposed as a possible 'black hole star'—a dense hydrogen-rich structure powered predominantly by matter falling into a massive central black hole rather than conventional stellar nuclear fusion.
object को possible 'black hole star' माना गया है—एक hydrogen-rich structure जिसमें energy conventional stellar nuclear fusion के बजाय massive central black hole में गिरते matter से आती है।
