The Gum Nebula is so large and close it's actually hard to see. This interstellar expanse of glowing hydrogen gas frequently evades notice because it spans 35 degrees — over 70 full Moons — while much of it is pretty dim. This 90-degree wide mosaic was designed to be both wide and deep enough to bring up “the Gum”—visible in red on the right. The image was acquired late last year with the background — including the Milky Way's central band — captured by the same camera and from the same location in Shangri-La, Yunnan, China.
“Working closely with the bears and getting them used to our behaviour meant that by day 5 we were well underway to documenting some truly unique behaviour. By this point we have gotten to know in detail the personalities of 27 different bears, and they in return welcomed us into their lives and let us film around the clock. Utilizing drones, remote cameras, and custom made gear in order to capture the most intimate footage.” | Martin Gregus
A foggy morning in downtown Dubai. Very rare conditions, caused by the cold nights and warm mornings, set the perfect scene for an aerial photo. The iconic buildings of Dubai emerging out of the low clouds create an impression that the city is floating in the sky. | Hugo Healy

At night you can follow this road as it passes through the Dark Sky Alqueva reserve not too far from Alentejo, Portugal. Or you could stop, look up, and follow the Milky Way through the sky.
Scientists around the world have noted that the Earth has been spinning on its axis faster lately—the fastest ever recorded. Several scientists pointed out that this past year saw some of the shortest days ever recorded as well.

How far are you from a naturally dark sky?
In increasing steps, this world map (medium | large) shows the effect of artificial brightness on the visual appearance of the night sky, modeled using high resolution satellite data and fit to thousands of night sky brightness measurements.
A bright, colorful Perseid meteor flash was captured during this 20 second exposure. It made its ephemeral appearance after midnight, in the moonless skies over the broad granite dome of Enchanted Rock State Natural Area, central Texas. Below the Perseid meteor, trees stand in silhouette against scattered lights along the horizon and the faint Milky Way, itself cut by dark clouds of interstellar dust.
A rare roll-call of planets has been occurring in the morning sky for much of June. This fisheye all-sky image, taken a few mornings ago near the town of San Pedro de Atacama in Chile, caught not only the entire planet parade, but the Moon between Mars and Venus. Left to right are Saturn, Neptune, Jupiter, Mars, Uranus, Venus, and Mercury.
The Vaccanonesa is a small train that connects the city of Trento, Italy with the villages of Val di Non and Val di Sole in Trentino. During its ride through the apple orchards, the train makes this passage above a gorge over 150 meters high.
Enjoyed this very much.
