A team of scientists used light from carbon ions in a distant galaxy to determine the rotation speed of gas around the central object. A sharp acceleration of the gas toward the center pointed to a black hole with a mass of about 6.3 billion Suns. This is the first dynamical weighing of a black hole

Astronomers peered into the early Universe and saw how three massive galaxies, merging, eject gas. This gas compresses into clumps resembling necklace beads and glows brightly. These cosmic 'jewelry' pieces are an important stage in the construction of the most massive galaxies.
