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

The University of Texas at Austin team that led a twin satellite system launched in 2002 to take detailed measurements of the Earth, called the Gravity Recovery and Climate Experiment (GRACE), reports in the most recent issue of the journal Nature Climate Change on the contributions that their nearly two decades of data have made to our understanding of global climate patterns.

The results of a recent study conducted by the NASA Lunar Reconnaissance Orbiter, the agency's automatic interplanetary station, show the existence of 'permafrost' near the poles of the moon with a relatively high content of water ice (up to 5% by weight). It is believed that water ice could supply a life support system for the future Russian Lunar Station, and that it could also produce hydrogen-oxygen fuel for flights into deep space. […]

The US president, Donald Trump, has stuck to his plan to send humans back to the moon in the next five years, recently giving the project a US$1.6 billion shot in the arm. Whether he succeeds or not, the first successful landing on the lunar far side by China, the European Space Agency's recent "lunar village" concept and a myriad of private companies all gearing up for commercial human spaceflight indicate that a human return to the moon may be about to begin in earnest.

Wind has shaped the face of Mars for millennia, but its exact role in piling up sand dunes, carving out rocky escarpments or filling impact craters has eluded scientists until now. […]
Neptune's moon Triton fosters rare icy union
on May 22, 2019 at 6:00 pm
Astronomers using the Gemini Observatory explore Neptune's largest moon Triton and observe, for the first time beyond the lab, an extraordinary union between carbon monoxide and nitrogen ices. The discovery offers insights into how this volatile mixture can transport material across the moon's surface via geysers, trigger seasonal atmospheric changes, and provide a context for conditions on other distant, icy worlds.
