How can a telescope orbiting Earth detect light emitted from the far side of the sun? NASA scientists tried to figure out the answer after the Fermi Gamma-Ray Space Telescope recorded gamma rays, the highest-energy form of light, originating from solar flares on the far side of the sun on three separate occasions. NASA’s Solar Terrestrial Relations Observatory (STEREO) spacecraft captured images of each event from the far side, allowing scientists to connect these “beyond-the-limb” solar flares with observations from Fermi. Studying the sun may help scientists predict solar flares, which, when aimed at Earth, can cause both beautiful auroras and communications system disruptions.

Jeneria Lekilelei, a warrior from the Samburu tribe of Northern Kenya, has dedicated his life to wildlife conservation. In 2010 he founded Warrior Watch to encourage Samburu men to conserve lions. Since then, the local lions population has risen from 11 animals to 50. However, increased periods of drought in recent years force wildlife and people to compete for the same resources, oftentimes causing conflict. Watch as Lekilelei and his team fight to protect lions under the harshest conditions.
