A superearth 111 light years away shows evidence of water vapor in its stratosphere, reports National Geographic. Water on another world.
The discovery, announced this week in two independent studies, comes from years of observations of the exoplanet K2-18b, a super-Earth that’s about 111 light-years from our solar system. Discovered in 2015 by NASA’s Kepler spacecraft, K2-18b is very unlike our home world: It’s more than eight times the mass of Earth, which means it’s either an icy giant like Neptune or a rocky world with a thick, hydrogen-rich atmosphere.
Even at a tenth of the speed of light, that's a thousand-year trip.

I’ve personally launched this same rocket design, an Estes E2X Amazon, many times and can vouch for its fine engineering […]
UPDATE: Launch scrubbed due to weather just a few minutes before launch. See you Saturday for another try! Today, a SpaceX Falcon 9 rocket and Crew Dragon capsule is scheduled to shuttle two NASA astronauts to the International Space Station. This will be the first time humans will launch to space from the United States […]

Just as in almost any industry that seeks high-demand, well-trained workers, certification often becomes key. For project managers, that means anyone who’s serious about serving in that role with a respected company knows they’re going to need the seal of approval in one of the field’s most recognized methodologies before they stand much of a […]
Popping a new battery in a smoke detector or adding salt to your water softener are easy fixes. But if you run into trouble or a necessary repair in a cramped, tight place, sometimes with no obvious fix or easy access, it can be a pretty frustrating exercise. Since flying blind is the absolute worst, […]
