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.

Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo’s “falling bodies” experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance. screengrab via Wonders of Physics/YouTube (Digg)
On Tuesday evening, the night before NASA astronaut Bob Behnken was set to launch into orbit about a SpaceX Falcon 9 rocket and Crew Dragon capsule, he launched his own rocket from Florida’s Atlantic Coast.
Software apps are a dime a dozen. Well, if you’re going by their actual monetary cost, maybe not really. But considering how useless some poorly conceived, poorly executed apps are at doing the job you actually downloaded them to accomplish, it isn’t a stretch to think that many apps aren’t even worth a free download. […]
With everything happening in the last few months, we all but guarantee no one has been thinking about their taxes. That’s understandable — because, beyond all of our current concerns, nobody enjoys the whole tax filing process during even the best of times. Unfortunately, Benjamin Franklin was right — taxes truly are as inescapable as […]
Most parents know that giving their kids educational toys and other projects will expand their minds. But what many might not realize is that physical play is actually building their mental abilities as well. Studies are still in beginning stages, but some early research supports the theory that kids who get the chance to get […]
