Credit: NASA / JPL-Caltech ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anew instrument aboard the International Space Station (ISS) has been used to identify more than 50 “super-emitters” of methane — a major step toward slashing global warming. The challenge: To combat global warming, we need to cut our greenhouse gas emissions. Carbon dioxide accounts for the majority of those emissions, and transitioning from fossil fuels to clean energy will significantly reduce those. Methane is a much less common greenhouse gas than CO2, but it’s far more potent, with each ton emitted causing 80 times as much warming in...

Mars’ moons: Mars has two moons. The larger of them, Phobos, is 14 miles wide and orbits the planet from a distance of just 3,700 miles, while the smaller one, Deimos, is only 9 miles in diameter and circles it from 14,580 miles away. “We expect to … advance our fundamental understanding...
