Magnetic Tremors Help Show Space Storms
According to a recent release from NASA, a team of University of Alberta researchers has discovered a new way to track and predict space storms before they impact Earth's atmosphere.
The team's study reveals that magnetic blast waves can be used to pinpoint and predict the location where space storms dissipate their massive amounts of energy. These storms can dump the equivalent of 50 gigawatts of power, or the output of 10 of the world's largest power stations, into Earth's atmosphere.
To track these storms, the team uses ground-based observatories spread across northern Canada and the five satellites of the THEMIS space mission to detect magnetic disturbances as storms crash into the atmosphere. Using a technique the researchers call "space seismology," they look for the eye of the storm hundreds of thousands of miles above Earth. To find the strongest point in the storm, the team uses magnetic sensors at various points both on the ground and in space to learn more about space storms and how they interact with Earth's magnetic field.
