The universe is incredibly big. But how do astronomers know that? Billion-mile-long tape measures can't be found at the hardware store. Instead, astronomers use the expansion of the universe itself to establish milepost markers. The light from remote objects is attenuated and weakened as space stretches like a rubber band. The consequences are that starlight will...

Pacific white-sided dolphinThe Pacific white-sided dolphin or “lag” (Lagenorhynchus obliquidens) is a familiar sight to boaters from California to Korea.

Their intense curiosity about boats makes it difficult for sci...
