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

Using the Cooled Mid-Infrared Camera and Spectrometer (COMICS) on the Subaru Telescope, astronomers have detected an unidentified infrared emission band from comet 21P/Giacobini-Zinner (hereafter, comet 21P/G-Z) in addition to the thermal emissions from silicate and carbon grains. These unidentified infrared emissions are likely due to complex organic molecules, both aliphatic and aromatic hydrocarbons, contaminated by N- or O-atoms. Considering the properties of the dust and organic molecules, […]

Stars form within giant clouds of gas and dust that pervade galaxies like our own Milky Way. This image depicts one such cloud, known as Orion A, as seen by ESA's Herschel and Planck space observatories.
A battle for the jet stream is raging above our...

When prolonged periods of severe weather strike, two things often get the blame these days: climate change and the jet stream. Many have expressed concerns that the rapidly melting Arctic is now disturbing the jet stream, bringing more frequent bouts of wild weather. But potentially even more powerful changes are afoot in the tropics—and the consequences could be severe.
