Magnetic fields can replace bulky centrifuges in space oxygen systems, making them lighter, more efficient and better suited for deep-space missions, a new study finds.

Aboard the International Space Station, astronauts use creativity and culture to make life in orbit feel a little more like home.

"Since I landed in Lucknow around 7:30 this morning, I must have clicked about 2,000 selfies."

Mercury passes 1.2° north of Regulus at 6 A.M. EDT; the pair is visible in the east just before sunrise, but it might be a challenging observation. You’ll want to get to a location above the surrounding terrain if possible, with an eastern horizon free of tall trees or buildings.  Rising around 5:30 A.M. localContinue reading "The Sky Today on Tuesday, September 2: Mercury meets Regulus"
