Milky Way may be missing mass after stars seen behaving strangely, study says

(CNN) – Scientists have determined our galaxy may weigh less than previously thought.

Weighing a galaxy is a complicated process that involves measuring the speed at which stellar bodies travel and extrapolating from there to determine a galaxy’s total mass.

Researchers now believe our galaxy is the weight of trillions of suns combined lighter.

They arrived at this hypothesis using recent measurements from the European Space Agency’s Gaia satellite.

The measurements show suspiciously slow-moving stars on the outskirts of the Milky Way.

The new findings have profound implications for scientists’ understanding of dark matter.
