This hoverboard costs $20,000 and can fly for six minutes
2015 was literally and figuratively the year of the hoverboard. While everyone was talking about the self-balancing scooters, two companies showed off skateboard-shaped boards that actually hovered a few inches above the Earth: Lexus with the “Slide” board, and Arx Pax with its second generation Hendo Hoverboard. Now, just days before the new year, another company called ArcaSpace is taking a shot at making the mythical hoverboard.
ArcaSpace is primarily a private space company, and one of the original 26 teams that competed in the Ansari X Prize competition in 2004. (It also entered the Lunar X Prize competition, too, before pulling out in 2013.) But early this morning the company released a video that shows off the “ArcaBoard,” a fan-powered rectangle that can lift a person off the ground by almost a foot.
The ArcaBoard gets its power — 430 pounds of thrust, or 272 horsepower, according to the company — from 36 electric fans. The company also says its built in some self-balancing tech to make it fly smoothly. Beyond that, though, it doesn’t look like there’s much to the experience. Dumitru Propescu, ArcaSpace’s CEO, is seen riding it in the video, but it doesn’t look like he has much control over where it’s going. It’s actually pretty reminiscent of the Hendo Hoverboard videos — sure, it hovers, but you can’t really steer it enough to ever use it to get anywhere.

Super-Earth In Outer Solar System Is Incredibly Unlikely
How an innocent plea for collegial comments turned into a global news flap about a possible Super-Earth on our solar system’s outer fringes.
The odds that our solar system harbors a super-Earth on its outer fringes are longer than the chances of winning a state lottery (or at least 200 million to one), says a University of Hawaii planetary scientist. In fact, the recent news flap over the potential detection of a rocky planet in a very long solar orbit was greatly exaggerated, the lead author of the scientific paper which resulted in the controversy now says.
“We never claim a super-Earth; we state it can’t necessarily be ruled out on the basis of our data alone, but the much more likely explanation is a much more nearby icy-body,” Wouter Vlemmings, a radio and submillimeter astronomer at Sweden’s Chalmers University of Technology, told me.
But Jonathan Williams, a longtime submillimeter astronomer and planetary scientist at the University of Hawaii in Manoa, who was not involved in the observations, couldn’t disagree more, particularly since super-Earths are thought to have masses that range from between 1 to 10 times that of Earth.
‘Star Wars’ Tech: 8 Sci-Fi Inventions and Their Real-Life Counterparts
While the science and technologies behind the franchise are firmly rooted in fantasy, their enduring appeal has served as inspiration for many real-life scientists and engineers. Here are some of the most notable attempts to turn “Star Wars’” science fiction into science fact.

No Man’s Sky game promises universe of 18 quintillion planets
Due for release in June 2016, No Man’s Sky will allow you to visit and explore a virtual universe of trillions of planets, each one a unique world.
China wants to begin manned deep space missions
China wants to be the leading force in manned space exploration, and is exploring sending people to the far side of the moon, Mars, asteroids, and further into deep space.
Becoming the second largest economy in the world and an emerging superpower of its own, China wishes to add deep space exploration into its achievement portfolio. Besides the ongoing moon exploration, its scientists are considering going deeper into the solar system, including Mars, asteroids, and even manned deep-space mission. Liu Jizhong, director of the lunar exploration program and space engineering center, pointed out that China has to be more pioneering, tackling problems such as high speed deep space exploration, energy and power generation, space robot development, and more. He also said that China must cooperate with others as space exploration is an undertaking shared by the entire human species.
China currently intends to explore the far side of the moon, something that has never been done before. It would require a relay satellite for communication and navigation on Lagrange point, where the satellite could orbit within the combined gravitational pull of the Earth-moon system, as said by Zhang Lihua of China Spacesat Co. While China believes that robots are critical to the mission, it also believes that these trips must be manned in order to effectively leverage human decision-making. China also says they are designing footed robots to explore asteroids and better understand their material composition.
Nearby star hosts closest alien planet in the ‘habitable zone’

A simulation of the orbital configuration of the Wolf 1061 system. Wolf 1061 is an inactive red dwarf star, smaller and cooler than our sun, 14 light years away. The planetary habitable zone around the star is marked in green — the colors grade from red (where a planet would be too hot), through green (where the surface of a planet could sustain liquid water), through to blue (where a planet would be too cold).

UNSW Australia astronomers have discovered the closest potentially habitable planet found outside our solar system so far, orbiting a star just 14 light years away.
