A new device is an anti-solar panel, harvesting energy from the cold night sky. By harnessing the temperature difference between Earth and outer space, a prototype of the device produced enough electricity at night to power a small LED light. A bigger version of this nighttime generator could someday light rooms, charge phones or power…

  Methane released in Gale crater stays in Gale crater. An overnight change in the Martian atmosphere could hold the gas close to the ground until morning, explaining why the Curiosity rover caught a whiff of methane while an overhead orbiter found none. The theory offers “a way for the two measurements to live in…
