The 2020 update, released Dec. 10, includes a new feature: blackout zones. “We’ve added something new that we call blackout zones, and these are areas around the north and south magnetic poles which ...

As well as revealing ore deposits, magnetic anomalies can also show areas of ground water and sea weakness zones. It is a useful tool for geologists and geophysics, as well as a teaching resource. The ...

The sun's magnetic field generates regions in the sun's atmosphere, often rooted by sunspots, that store vast amounts of energy that fuel explosive solar storms and drive space weather.

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

What is the 'battle zone'? In addition to the 11-year sunspot cycle that most people are familiar with, the sun also has a longer 22-year "Hale cycle," which is the time it takes for our home star ...

TRUE north, magnetic north and grid north have met for the first time in map reading history — at a drainage pipe in Dorset. The three ways of measuring north usually do not align perfectly.

Magnetic anomalies. In total, the maps cover around 21 square miles (55 square kilometers) and account for about 68 percent of the lake’s floor.
