Scientists Have Identified the Origin of an Extraordinarily Powerful Outer-Space Radio Wave

wired.com Jorge Garay 2025-11-01 22:49:17

The Earth is constantly receiving space signals that contain vital information about extremely energetic phenomena. Among the most peculiar are brief pulses of extremely high-energy radio waves, known as fast radio bursts (FRB). Astronomers compare them to a powerful lighthouse that shines for milliseconds in the middle of a rough, distant sea. Detecting one of these signals is an achievement in itself, but identifying its origin and understanding the nature of its source remains one of the grea

Leaky Ice Dam Prompts Evacuations in Alaska as Record Floods Loom

A water basin in Alaska is overflowing its ice dam, the Mendenhall Glacier, and flooding the state capital, Juneau. Experts expect the likely record-breaking event to peak today, and officials have asked residents in parts of the city and borough to evacuate. The flood doesn’t come as a surprise. Years ago, a small glacier on the other side of Mendenhall Glacier—which is just 12 miles (19 kilometers) from Juneau—receded and left a basin in its wake, according to the Associated Press.
