Powerful solar storm likely detonated mines during Vietnam War

A strong solar storm in 1972 caused widespread disturbances to satellites and spacecraft, and may have led to the detonation of mines during the Vietnam War, according to new research showing the event may have been a more devastating solar storm than previously thought. In a new study, researchers pieced together data and historical records related to the solar activity of 1972 to better understand the nature of the solar storm. In the process, they uncovered an incident where sea mines off the coast of Vietnam were detonated by the solar event.

Sounds of a Solar Storm

High school students listening to audio tracks of NOAA satellite data have identified the sounds of solar storms buffeting Earth’s magnetic field. The results of a UK-led citizen science project suggest that the approach of converting physical data into sound signals could help NOAA and other scientists make sense of massive amounts of data from satellites and other instruments.

New technology could improve radiation risk warnings for future deep-space astronauts

New technology that detects radiation from the Sun in real time and immediately predicts subsequent health risks could protect astronauts on future deep-space missions, according to a new study. Astronauts face dangers during solar energetic particle, or SEP, events, which occur when an eruption in the Sun’s atmosphere hurls high-energy protons out into space. These protons can penetrate the walls of a spacecraft and enter the human body. This radiation can cause immediate effects such as nausea, performance degradation and other acute radiation syndromes, while long-term effects can include cancer, degenerative tissue damage, heart disease and damage to the central nervous system.

Impending weak solar activity could expose aircrews to higher radiation levels

Aircrews and frequent fliers may soon experience an uptick in radiation exposure due to the upcoming low point in the solar cycle, when weak solar activity provides less protection against cosmic rays entering the atmosphere.
