The Daya Bay Neutrino Experiment has produced the most precise measurement yet of theta13, a key parameter for understanding how neutrinos change their flavor.
Astronomers connect the dots between two strange doppelganger galaxies, uncovering what might be a string of galactic pearls created in a cosmic collision 8 billion years ago.
The result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies.
