Hubble Reveals Dark Matter Patterns in Draco Dwarf Galaxy

New 3D star motion analysis uncovers potential cusp-like structure within the dark matter distribution.

Astronomers used 18 years of Hubble data to map stars' movements in the Draco dwarf galaxy.
The study offers the most accurate 3D understanding of stellar dynamics in a dwarf galaxy to date.
Findings suggest a cusp-like dark matter distribution, aligning with existing cosmological models.
The research reduces assumptions from previous studies by incorporating detailed star and dark matter characteristics.
Methodologies from this study are being applied to other dwarf galaxies to better understand dark matter properties.
