NASA has released the first ever images of mysterious polar night clouds that form 50 miles above Earth’s surface, and says that they might be linked to global warming.
The startling images were captured by NASA’s “AIM” satellite (Aeronomy of Ice in the Mesosphere), and show night clouds above 70 degrees north latitude on May 25. Since then, eyewitnesses on the ground have reported seeing the formations on June 6 over Northern Europe (see image after the jump).
When viewed from space, the mysterious clouds are known scientifically as Polar Mesospheric Clouds, or PMCs, when seen from the ground they are called Noctilucent or “night-shining” Clouds.

An Australian scientist has developed a new method of manufacturing solar cells using nothing more than some nail polish remover, a pizza oven and a standard inkjet printer.
The iJET technique is so easy and cheap to carry out that it could revolutionize access to solar technology in the developing world.
In a recent radio interview (audio), Nicole Kuepper, a 23 year-old PhD student at the University of New South Wales, explained the process.

I forgot how much fun it is to make a collage but after seeing this collage by Justyn Hegreberg, I can’t wait to dive in!
Justyn’s work is so interesting and original because he uses recycled photographs (mostly doubles and blurry snapshots collected from Craigslist) and a paper shredder to create his signature look.
I love this idea to use a paper shredder to cut the paper, just think of the possibilities!
