polar : (a) of or relating to a geographic pole or the region around it (b) coming from or having the characteristics of such a region — Webster
Polar regions of Earth also known as Earth’s frigid zones, are the regions of Earth surrounding its geographical poles (the North and South Poles). These regions are dominated by Earth’s polar ice caps, the northern resting on the Arctic Ocean and the southern on the continent of Antarctica. — Wikipedia

- Are the northern lights caused by 'particles from...on January 21, 2022 at 12:30 pm
What a spectacle a big aurora is, its shimmering curtains and colorful rays of light illuminating a dark sky. Many people refer to aurora as the northern lights (the aurora borealis), but there are southern lights too (the aurora australis). Either way, if you're lucky enough to catch a glimpse of this phenomenon, it's something you won't soon forget.

Black holes are intriguing and widely studied cosmic bodies with extremely high tidal forces, from which even light is unable to escape. While many studies predicted the existence of black holes, which have also recently been detected, many questions about these cosmic bodies remain unanswered.
- Polar ice contaminated with nanoplasticson January 20, 2022 at 2:41 pm
Decades-old polar ice contains significant amounts of nanoscale plastic particles. Studying ice cores from Greenland and Antarctica, an international team of scientists have identified several types of nanoplastic particles, including particles that originate from tires. As nanoplastics may cause toxic effects, the researchers address that remote and pristine areas may contain more nanoparticle pollution than expected.

A team of researchers from the Norwegian Polar Institute, Uppsala University, Princeton University and California Institute of Technology reports that the rate of glacial melt in a Norwegian archipelago, Svalbard, is speeding up as global warming continues unabated. In their paper published in the journal Nature, the group describes a unique method of measuring glacial melting that produced an estimate of the rate of melting in the future. Twila Moon with the University of Colorado has […]
