A Mars Rover’s Selfie, An Eiffel Tower On The Sun, And Other Amazing Images of the Week

Plus baby wolves
The Mars Rover took some time out of its busy schedule exploring a new frontier this week to take a selfie near some hydrated minerals. It was taken at a drilling site called Buckskin, where DAN Principal Investigator Igor Mitrofanov says that there is three to four times more water than has been found anywhere else on the planet.

This picture confirms the first pack of wild grey wolves seen in California since 1924. The pup are a few months old, according to park officials, and other photos show a single adult wolf. “We knew wolves would eventually return home to the state, and it appears now is the time,” said Charlton H. Bonham, Department of Fish and Wildlife director, in a statement. Handout/ Reuters
The expression “made out of thin air” has always been just that—an expression. But now it’s a reality, according to research from George Washington University. The team used solar powered diodes to superheat lithium oxide and salt, and when that mixture reacted with the air it created carbon nanofibers, as well as lithium carbonate and oxygen. It’s only been done on a small scale, but if made larger, the sky is literally the limit. Researchers hope this technology can work in tandem with construction and even the production of lithium-ion batteries. Stuart Licht/Nanoletters
