The Pineapple Express — an atmospheric river originating in the tropical Pacific — walloped western North America in February 2017. These systems are becoming more frequent at higher latitudes, leaving mid latitudes drier.

Atmospheric rivers are shifting toward the poles, possibly following a long-term cycle

The gravitational waves emitted by the merger of black holes, when lensed by massive objects as the waves travel toward Earth can be used to calculate the rate at which the universe is expanding

Astrophysicists propose a new way of measuring cosmic expansion: lensed gravitational waves
