Mines like these, deployed in waters off the coast of Vietnam just 3 months earlier, suddenly detonated without explanation in August 1972. The event was attributed to “magnetic perturbations of solar storms.” Credit: U.S.

Declassified files are showing researchers the unpredictable nature of the Sun and helping them work towards predicting the next big solar storm. Seeker sat down with Smead Aerospace Research Professor Delores Knipp to find out more. Watch the full

On Aug. 4, 1972, U.S. military pilots flying south of Haiphong harbor in North Vietnam saw something unexpected: more than two dozen sea mines suddenly—and without apparent explanation—exploding in the water.  Now, CU Boulder engineering

Few people have heard of Hisako Koyama, but the dedicated female solar observer, born in Tokyo in 1916, created one of the most important sunspot records of the past 400 years, according to new research published by the American Geophysical Union.

A heads-up for commercial air crews and other frequent fliers: The risk of exposure to radiation particles screaming Earthward from space may increase a bit in the next few years as the activity of our sun decreases, says a CU Boulder professor.

Congratulations to research professor Delores Knipp, who has been selected to give the 2017 CEDAR Prize Lecture. Knipp is receiving the honor for her space weather research “unraveling the physical connection between shock-led interplanetary coronal

A team led by CU Boulder has found the mechanism behind the sudden onset of a “natural thermostat” in Earth’s upper atmosphere that dramatically cools the air after it has been heated by violent solar activity. Scientists have known that solar
