A new way to measure galactic size Tracing the brightness of a galaxy's gas, rather than of its stars, reveals a boundary between the galaxy and intergalactic space. Jennifer Sieben Echoes of El Niño and La Niña affect the Atlantic a year later Anomalously warm or cold tropical Pacific waters are known to have immediate global effects. A newly identified long-distance correlation takes months to emerge.

The following tribute was delivered as part of the award ceremony. John A. Wheeler You might have missed Gamma-ray flashes offer clues about thunderstorm electrification Newly observed high-energy atmospheric flashes show that clouds glowing with gamma-ray radiation are more dynamic than previously thought. Alex Lopatka FROM THE OCTOBER MAGAZINE The promises and perils of a mid-career pivot Astrophysics to physical oceanography. String theory to machine learning. High energy theory to biophysics. Such leaps in research focus can be challenging—and rewarding.
