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

In February 2020, NASA's Solar Dynamics Observatory—SDO—is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the sun, studying how the sun creates solar activity and drives space weather—the dynamic conditions in space that impact the entire solar system, including Earth.

The cosmic confusion of the microwave background
on February 10, 2020 at 1:39 pm
Roughly 380,000 years after the Big Bang, about 13.7 billion years ago, matter (mostly hydrogen) cooled enough for neutral atoms to form, and light was able to traverse space freely. That light, the cosmic microwave background radiation (CMBR), comes to us from every direction in the sky, uniform except for faint ripples and bumps at brightness levels of only a few part in one hundred thousand, the seeds of future structures like galaxies.
