The Sun Reverses its Magnetic Poles


his visualization shows the position of the sun's magnetic fields from January 1997 to December 2013. The field lines swarm with activity: The magenta lines show where the sun's overall field is negative and the green lines show where it is positive. A region with more electrons is negative, the region with less is labeled positive. Additional gray lines represent areas of local magnetic variation.

The entire sun's magnetic polarity, flips approximately every 11 years - though sometimes it takes quite a bit longer -- and defines what's known as the solar cycle. The visualization shows how in 1997, the sun shows the positive polarity on the top, and the negative polarity on the bottom. Over the next 12 years, each set of lines is seen to creep toward the opposite pole eventually showing a complete flip. By the end of the movie, each set of lines are working their way back to show a positive polarity on the top to complete the full 22 year magnetic solar cycle.

At the height of each magnetic flip, the sun goes through periods of more solar activity, during which there are more sunspots, and more eruptive events such as solar flares and coronal mass ejections, or CMEs. The point in time with the most sunspots is called solar maximum.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

How Cold Can It Get? The Lowest Temperatures Ever Recorded, Mapped

We often talk about record heat , especially in the context of climate change. But on the flip side, our planet also experiences cold so extreme it defies belief—temperatures that can flash-freeze exposed skin and halt life as we know it. These are not just numbers on thermometers; they’re snapshots of how Earth's atmosphere behaves under specific conditions—altitude, wind patterns, and location far from the moderating effects of oceans. The coldest temperature ever recorded on Earth? That title goes to Vostok Station in Antarctica, where scientists measured a bone-cracking −89.2°C (−128.6°F) on July 21, 1983. Located on the East Antarctic Plateau, Vostok is more than 1,000 kilometers from the South Pole and sits atop about 3.7 kilometers (2.3 miles) of ice. It’s isolated, dry, and high—three ingredients that make for perfect deep freeze conditions. The world map below created by VividMaps shows the lowest temperature ever recorded by country.

Mapping the Hottest Temperatures Ever Recorded on Earth

 When summer arrives, it brings not only vacation season but also some of the most extreme heat waves across the globe. While many people associate summer with warm, sunny days, some regions endure scorching temperatures that push the limits of human endurance. To put these extremes into perspective, we’ve mapped the highest temperatures ever recorded in countries around the world. The maps below, created by Vivid Maps , illustrate these record-breaking temperatures and the patterns of extreme heat across the globe. The Hottest Temperature on Record According to historical weather data, the highest reliably recorded temperature on Earth is 56.7°C (134°F) , measured in Death Valley, California , on July 10, 1913 . However, an even higher temperature of 58°C (136.4°F) was reportedly recorded in El Azizia, Libya , on September 13, 1922 . While this Libyan record stood for decades, some meteorologists have questioned its accuracy due to inconsistencies in measurement methods at the ti...
