Astronomers using the Hubble Space Telescope have uncovered new insights about Omega Centauri, the largest and brightest globular star cluster in the Milky Way halo. Located 15,000 light-years away, the massive cluster packs roughly 10 million stars older than the Sun into a volume measuring 150 light-years across, offering key details on galactic formation and stellar evolution.
What makes Omega Centauri unique?
Omega Centauri stands out from typical star clusters because it contains diverse stellar populations with a wide spread of ages and chemical abundances. Scientists believe these unique characteristics indicate that the cluster may be the remnant core of a small galaxy that merged with the Milky Way long ago.
What did Hubble discover at its center?
A detailed two-decade-long exploration conducted with the Hubble Space Telescope revealed compelling evidence pointing to a massive black hole located near the center of Omega Centauri.
