Hubble unveils first images of ongoing star cluster mergers near center of dwarf galaxies

Hubble Telescope snaps 1st images of clashing star clusters at the hearts of dwarf galaxies

Using the Hubble Space Telescope, astronomers have, for the first time, directly detected the merger of star clusters at the heart of dwarf galaxies.

Hubble gets first images of star cluster mergers in the centres of dwarf galaxies

NASA’s Hubble Space Telescope continues to break new scientific ground despite being usurped by the more advanced James Webb Space Telescope. A new study published in Nature reveals images from Hubble which are the first to show ongoing mergers of star clusters near the centres, or nuclei, of dwarf galaxies.

Hubble unveils first images of ongoing star cluster mergers near center of dwarf galaxies

A new study reports the first direct observation of merging star clusters in the nuclear region of dwarf galaxies. This detection confirms the feasibility of this formation route for nuclei in dwarf galaxies, which has long been debated. The study was published in Nature, and led by Postdoctoral Researcher Mélina Poulain from the University of Oulu, Finland.

More than ten years ago, the Herschel space telescope stopped its work. Thanks to a new analysis, its data may have solved a mystery.

The observation succeeded an international research team with the Hubble Space Telescope and confirms a decade-old theory on dwarf galaxies.
