I'm fascinated by painting of an extrasolar planet, credited to "Beau.TheConsortium" and apparently first posted to this SF Wiki. They're called "eyeball planets" -- similar to Earth, but tidally locked with their star, creating a vast polar ice cap on the dark side, a scorching desert facing the sun, and a band around the center where water melts from one side to the other and life happens. The extremes involved have made them a hot topic among those searching for life.
The sweet spot—let’s call it the “ring of life”—is at the terminator, the boundary between night and day. The ring of life is bounded by deserts on one side and ice on the other. There is a constant flow of water from the night side to the day side—a series of rivers, all flowing in the same direction. The Sun is fixed in the sky right at the horizon, and the area is in permanent light. Conditions are pretty much the same all the way across the ring of life. One can imagine vegetation following the rivers onto the day side until they dry up, with different ecosystems interspersed along the way. There could be mountains at the edge of the ice sheets, since the ice-covered continents would be heavily weighed down

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 […]
NASA announced today that the agency is moving ahead with a planned mission to Jupiter’s moon Europa. In this next phase, engineers will complete the final design, construction, and testing of the Europa Clipper spacecraft for a launch as soon as 2023. Why the icy moon Europa? From NASA: NASA’s Europa Clipper mission will conduct […]
When it comes to data analytics or deep learning, there’s one language behind the apps and algorithms that power the biggest companies of today: Python. The best part about this tool is that as versatile as it is, it’s actually fairly easy to learn. But mastery? For that, you need more than just a beginners’ […]
Your smartphone’s GPS is a modern necessity for some trips, but how do you use it safely? It’s been a problem ever since phones went mobile. A certain phone mount even shelled out the money for a commercial during the Big Game, so clearly there’s a market for the solution. Turns out there are a […]
