Consumed by the desert

I came across this a while back on Fast Company’s Co.Design, showing the abandoned town of Kolmanskop, Namibia, once home to German diamond miners. After the diamond fields dried up, residents gradually moved away, turning Kolmanskop into a ghost town by the 1950s and leaving it prey to the sands from the desert.

The photos are by Alvaro Sanchez-Montañes. His portfolio is increadibly impressive and definitely worth a look.

I came across this amazing photo while looking at the wikipedia entry on high dynamic range imaging.

Last night launch of the shuttle

STS-130 Space Shuttle Endeavor launch from the Intracoastal Waterway Bridge in Ponte Vedra, Florida; about 115 miles from the launch pad. This launch was extra special because it is NASA’s last scheduled night launch of the space shuttle program.

First photos of the atom

Last month physicists at the Kharkov Institute for Physics and Technology photographed the electron cloud of a single carbon atom. The images are the first real photographs of the electrons of a single atom, showing the s and p orbitals of a carbon atom.

Quantum mechanics states that an electron doesn’t exist as a single point, but spreads around the nucleus in a cloud known as an orbital. The soft blue spheres and split clouds seen in the images show two arrangements of the electrons in their orbitals in a carbon atom. The structures verify illustrations seen in thousands of chemistry books because they match established quantum mechanical predictions.

… and as for how it was done…

To create these images, the researchers used a field-emission electron microscope, or FEEM. They placed a rigid chain of carbon atoms, just tens of atoms long, in a vacuum chamber and streamed 425 volts through the sample. The atom at the tip of the chain emitted electrons onto a surrounding phosphor screen, rendering an image of the electron cloud around the nucleus

The sharper a sample’s pointed tip inside the vacuum chamber, the greater the resolution of the final image on the screen said Igor Mikhailovskij, one of the paper’s authors. In the last year, physicists learned to manipulate carbon atoms into chains. With the tip of the sample now just a single atom wide, the microscope was able to resolve the electron’s orbitals.

The Milky Way… from a cave in the Utah desert

The spiral galaxy, which cannot be seen with the naked eye, was captured by photographer Wally Pacholka using a 35mm camera and 50mm lens on a tripod with a 30-second exposure – long enough to collect the light but not to see the stars moving.
