Supermassive black holes not so massive say scientists
Observations show a quasar's central black hole has mass about one billion suns—roughly one-tenth prior estimates—challenging models of early supermassive black hole growth.
'Supermassive' black holes aren't as big as we thought, scientists say
Supermassive black holes in the early universe may be about ten times less massive than previously estimated, implying systematic overestimation from earlier measurement methods.
Black hole masses are measured via gravitational effects on companions, accretion radiation, and gravitational-wave signals across stellar to supermassive scales.

Scientists reveal when our galaxy's black hole will erupt into life
Sagittarius A*, a 4.3-million-solar-mass black hole, will likely awaken and feed when the Milky Way collides with the Large Magellanic Cloud in 2.4 billion years.
Extreme black hole system OJ 287 just got more interesting
Supermassive black holes exist within galaxies, significantly heavier than normal black holes, requiring advanced detectors like LISA for direct observation.
