How do you find a black hole you can't see? At the center of Omega Centauri, seven stars are moving fast enough to escape the cluster — yet they never leave. That contradiction points to an intermediate-mass black hole with at least 8,200 times the Sun's mass. SORABUMI breaks down how two decades of Hubble images uncovered it.
About 25 light-years from Earth, the Sun's ninth-closest white dwarf -- the burnt-out core of a dead star -- went unnoticed for 27 years, drowned in the glare of a red dwarf next door. Hubble's ultraviolet vision finally exposed four hidden dead stars within 65 light-years of home. SORABUMI explains how.
The spiral galaxy M88, 63 million light-years away, is losing its gas as it plows through the Virgo Cluster. Hubble's observations of this "ram pressure stripping" reveal the mechanism that decides a galaxy's fate — explained clearly.
