Northern stars trail around the celestial pole in this long exposure photo sequence from Fairbanks, Alaska.
The night sky at this far north latitude is very often dominated by dancing aurora. TWAN photographer, leading an aurora viewing tour, has captured the motion of stars, northern lights, and his group in this image. — Yuichi Takasaka

Opening the Curtains at Concordia
Set against a star-studded backdrop and a splash of the Milky Way, the green glow of an auroral curtain pervades the permanently dark winter skies of the South Pole.
The only sign of life here is the Concordia research station that ESA uses to prepare for future long-duration missions beyond Earth. The site also caters to scientific research from geology and glaciology to climate change, astronomy and planetary magnetic fields.
From the photographer:
Early in the morning, minutes before the tour group I was leading was to board the bus for Fairbanks, I shot this 12-segment all-sky panorama.
The aurora display was in recovery at the time, and three different forms were visible… low toward the south were “patches”, higher in the south was a wide and green “band,” and overhead appeared the eerie “black aurora”… not really aurora at all, but mysterious voids in which the aurora doesn’t appear.
Along the edge lies the snow-covered airfield of Chena Hot Springs Resort, colored green by the auroral light.
“During my first night in Fairbanks, Alaska in February 2012, the clouds broke a bit to reveal some auroral activity in the northern sky. The relatively low clouds are being lit by the reddish-orange light of Fairbanks.” — Dennis Mammana
