EarthSky Blog 9 Oct 2018, 10:00 UTC The star Proxima Centauri isn’t visible to the eye, but it’s one of the most noted stars in Earth’s sky. That’s because it is considered to be part of the Alpha Centauri star system, a triple system, and the nearest star system to our sun. Of the three stars in Alpha Centauri, Proxima is thought to be the one actually closest to our sun, at 4.22 light-years away.
Planetaria 9 Oct 2018, 04:49 UTC Human habitation of the Moon and Mars might still seem like a far-off dream, but visionaries are already taking incremental steps toward that goal. One such initiative comes from the EuroMoonMars project, which has just completed field tests of a prototype for human habitats and research stations, whose design is based on Japanese origami.
Scientific American 8 Oct 2018, 17:45 UTC Exploring the tropics of Jupiter’s ocean moon Europa would be no walk on the beach. Equatorial regions of the potentially life-supporting Europa, which harbors a huge ocean of salty liquid water beneath its icy shell, are probably studded with blades of ice up to 50 feet (15 meters) tall, a new study suggests.
Starts With a Bang! 8 Oct 2018, 14:06 UTC NASA’s Chandra X-ray observatory has shown us the Universe like nothing else ever before.
Scientific American 8 Oct 2018, 10:45 UTC In the 2016 blockbuster film Arrival, aliens with inscrutable motives descend on Earth—and it is up to a scientist played by Amy Adams to help communicate with them. Were this to occur in real life, it might be Sheri Wells-Jensen who gets the call. A linguist at Bowling Green State University, Wells-Jensen has thought a lot about just how different alien minds might be. Many researchers have automatically presumed extraterrestrials would possess senses like the ones most of us use every day. But Wells-Jensen's sensory experience of the world—as a blind person—has given her a rare perspective when it comes to imagining the alternatives and what they might mean for humans' ability to understand aliens.
