“Now we have a puzzle,” Wechsler said. “What in the Milky Way caused these small, lower-mass satellites to have their star formation quenched? Perhaps, unlike a typical host galaxy, the ...

Scientists are keen to get to the bottom of the dark matter puzzle because this phenomenon accounts for the vast majority of the "stuff" in the universe — about 85%, in fact. That means everything we ...
