"The supermassive object broke away from a nearby galaxy and is now racing through the intergalactic medium."
"A 'runaway' black hole ejected from its host galaxy is barrelling across space - and leaving behind a wake of newborn stars."
A supermassive object detached from a nearby galaxy and is speeding through the intergalactic medium. The object is a 'runaway' black hole that was ejected from its host galaxy and is moving at high velocity across space. The black hole's passage compresses ambient gas in the intergalactic medium and triggers star formation along its trajectory. Observations reveal a wake of newborn stars trailing the black hole, forming a visible stellar stream. The phenomenon links black-hole dynamics and star-formation processes outside galactic disks, showing that extreme gravitational events can seed stars in intergalactic space.
