Gas surrounding a supermassive black hole spews out from above and below the disk like a three-dimensional fountain, new simulations have revealed.
While it’s long been assumed that the rings of gas around active black holes took on the shape of a donut, researchers say the reality is far more complex.
Simulations and observations from the Atacama Large Millimeter/submillimetre Array (ALMA) suggest the ‘donut’ is actually a more dynamic structure made if three gaseous components that circulate constantly.
According to the team, it’s more of a three-step process. First, the cold gas forms a disk near the plane of rotation, heating up until the molecules break down. Some of these molecules are expelled above and below the disk. This falls back down to create a fountain-like structure read more
There’s a lot of high-tech gear you could haul into the outdoors these days, but there’s also plenty to be said for solutions that take a simpler approach. The Singapore-based designers behind the Ember Stove aren’t ones to complicate things, taking to Kickstarter with a compact two-piece cooking solution designed to fit in your pocket and fire up with just a handful of twigs. read more
NASA has revealed plans to take America back to the moon – but will rely on private firms to run the missions.
The space agency plans to work with nine private firms, ranging from small startups to giants like Lockheed Martin, to develop robotic landers and systems to mine the natural resources on the moon.
This will help develop the technology need for eventual manned missions, and NASA Administrator Jim Bridenstine pledged to have a manned lunar base within a decade.

Drones are a growing presence on the battlefield and recognizing that trend, the Russian Defense Ministry has ordered that all branches of its military begin training in anti-drone combat.
Russian newspaper Izvestia reports that the first test of these new tactics came in October during training exercises on the Black Sea. Ground forces will also begin training to repel drones. read more
As the shock-absorbing cartilage discs between our vertebrae degenerate due to aging, accidents or overuse, severe back pain can result. While some scientists have developed purely synthetic replacement discs, a recent test on goats indicates that bioengineered discs may be a better way to go. read more
