Why does Belgium shine so brightly? | BBC News
"Belgium's penchant for extravagant motorway lighting is suddenly in the spotlight thanks to pictures posted by French astronaut Thomas Pesquet.
The images of Europe taken from the International Space Station (ISS) have notched up tens of thousands of reactions on Facebook."

"Belgium can be seen glowing more brightly than its neighbours.
The country's dense road network enjoys near-total streetlight coverage, with lights kept on throughout the night. It uses about 2.2 million bulbs to illuminate Belgium's roads—with 186 bulbs per square mile, the New York Times reports:"

Panorama of the Milky Way Overhead

Alan: "A 360° degree fish-eye panorama of the Milky Way with the Galactic Centre overhead and the spiral arms of the Galaxy symmetrically displayed to either side of the core: toward Scutum, Aquila, and Cygnus at left; and toward Norma, Centaurus, and Carina at right."

"This is from near Coonabarabran, NSW, Australia at a latitude of 32° South. Scorpius and Antares are overhead at the zenith. The Dark Emu is visible across the sky, from his head in Crux at right, to his tail in Scutum at left. Jupiter is the bright object in the west at top. The glow of Gegenschein is below it. The view is with southeast to the bottom to place the plane of the Galaxy horizontally across the frame. Some airglow discolours the sky at left."

Technical details: This is a stitch of 8 segments, each a 1-minute exposure with the 14mm lens at f/2.6 and filter-modified Canon 5D MkII at ISO 3200. The camera was on a tracker, the iOptron Sky-Tracker, so the stars are not trailed. Stitched with PTGui.

Proton Arc over Minnesota

Thomas: "The aurora started as the sky darkened after sunset. There was a brief display, then this beam, to the east danced across the sky from east to west for 20 minutes along the Sawbill Trail in NE Minnesota tonight. The aurora danced as well!"
