Stars in the Milky Way are 'dipping' downward due to an invisible dwarf galaxy's flyby. This dark 'underachiever' never ignited a single star but left its mark on stellar motion. Findings like this shed light on how dark matter works.

🎯 If dark matter were visible, the night sky would be dotted with hundreds of tiny ghost galaxies circling the Milky Way.

🎬 'Dark galaxies' are like the ghost ships of science fiction — massive but invisible.
