NASA Finds Planets of Red Dwarf Stars May Face Oxygen Loss in Habitable Zones
NASA scientists are expanding the definition of habitable zones (the area around a star where a life-sustaining planet might lurk), taking into account the effect of stellar activity that can threaten exoplanets’ atmospheres with oxygen loss.

Antarctica’s Changing Larsen Ice Shelf
The Larsen Ice Shelf is situated along the northeastern coast of the Antarctic Peninsula, one of the fastest-warming places on the planet. In the past three decades, two large sections of the ice shelf (Larsen A and B) collapsed. A third section (Larsen C) seems like it may be on a similar trajectory, with a new iceberg poised to break away soon.

Looking Back: Dr. George Carruthers and Apollo 16 Far Ultraviolet Camera/Spectrograph
Dr. George Carruthers, right, and William Conway, a project manager at the Naval Research Institute, examine the gold-plated ultraviolet camera/spectrograph, the first moon-based observatory that Carruthers developed for the Apollo 16 mission. Apollo 16 astronauts placed the observatory on the moon in April 1972.

Lake Powell and Grand Staircase-Escalante
This panorama, photographed by an astronaut aboard the International Space Station, shows nearly the full length of Lake Powell, the reservoir on the Colorado River in southern Utah and northern Arizona. Note that the ISS was north of the lake at the time, so in this view south is at the top left of the image.
