In One Of The Biggest Science News Stories Of The Year, Astrophysicists Directly Observe A Black Hole Tearing Apart A Star
This year , for the first time ever , research worker at NASA were able todirectly observea supermassive black hole in the process of ripping apart a asterisk .
Thanks to an ethereal surveillance system locate at Ohio State University , along with a team of cosmonaut and researchers at NASA , the ultimate cosmic eventwas witness almost by chance event .
In order for a black hole to pull apart a mavin , the circumstance have to be just right . know as a tidal perturbation event ( TDE ) , the star - shredding is incredibly rare — pass off once every 10,000 to 100,000 yr in a galaxy the size of it of the Milky Way .
If the headliner ( which , in this case , was roughly the size of it of our sun ) wander too close to a black hole , it will simply be consumed whole without a trace left behind .
