BLEND/TRACKED “Summit Fever”
Having climbed Mont Blanc (15,780 ft/4.804m) via the classic Trois Monts (Three Mountains) route the day before I was pretty sure I wouldn’t have it in me to wake up at 1 am to take pictures. But since this was our last night on the mountain, my girlfriend and I mustered up the energy to wake up, cross the glacier into La Vallée Blanche (The White Valley) and watch the first mountaineers start their way up the mountain.
The mountain in the picture is Mt. Blanc du Tacul, the first of three mountains one must climb to make it to the top of Mt. Blanc via this route. The second is Mont Maudit and of course Mont Blanc (both not pictured), the highest peak in Europe. On the right of the picture is the Refuge des Cosmiques, where mountaineers usually sleep before making summit bids. And of course the lights on the mountain are teams of mountaineers ascending the mountain.
One of the most surprising things to me about taking pictures here is that the glow of the town Chamonix can be seen on the mountains face and the exposure of the sky. Crazy what a little light pollution will do.
All in all, very happy we woke up and getting to do some photography was a nice way to cap the trip!

brightening of the night sky caused by street lights and other man-made sources, which has a disruptive effect on natural cycles and inhibits the observation of stars and planets.
Future generations will lose out on the incredible views of the night sky unless we take action! •

The Antennae Galaxies (NGC 4038 [left] and NGC 4039 [right] or Caldwell 60/61) are a pair of merging galaxies, 45 million light-years away in the southern constellation Corvus, which are part of the NGC 4038 group with five other galaxies.
Rich deposits of neon, magnesium, and silicon were discovered from the Chandra X-ray Observatory analysis of the Antennae. These elements are among those that form the building blocks for habitable planets.
The Antennae Galaxies have two long tails of stars, gas and dust, thrown out of the galaxies as a result of the collision. During the course of the collision, billions of stars will be formed. Astronomers have recently discovered over a thousand bright young star clusters – the result of a burst of star formation triggered by the collision.
The nuclei of the two galaxies are joining to become one giant elliptical galaxy. Two supernovae have been discovered in the galaxies: SN 2004GT and SN 2007sr.
About 1.2 billion years ago, the Antennae were two separate galaxies. NGC 4039 was a spiral galaxy, somewhat larger than NGC 4038, a barred spiral galaxy.
About 900 million years ago the Antennae began to approach one another, and 600 million years ago the Antennae passed through each other. Some 300 million years ago, the Antennae’s stars began to be released from both galaxies.
Today the two streamers of ejected stars extend far beyond the original galaxies, making the antennae shape.
Within 400 million years, the Antennae’s nuclei will collide and become a single core with stars, gas, and dust around it.
