12 new moons have been found orbiting Jupiter and one is on collision course with the others — Researchers in the US stumbled upon the new moons while hunting for the mysterious ninth planet that is postulated to lurk far beyond the orbit of Neptune, the most distant planet in the solar system. The team first glimpsed the moons in March last year from the Cerro Tololo Inter-American Observatory in Chile, but needed more than a year to confirm that the bodies were locked in orbit around the gas giant. The fresh haul of moons brings the total number of Jovian moons to 79, more than are known to circle any other planet in our cosmic neighbourhood.
~ A head-on collision would create a crash visible from earth.
Odd asteroid duo — An asteroid discovered late last year is actually two gravitationally-bound objects in orbit around each other. But this particular duo, dubbed 2017 YE5, belongs to an exceptionally rare class of near-Earth objects. In June, the object made the closest approach it will make to Earth for the next 170 years, allowing scientists to take a closer look.
~ These self-orbiting rocks are as dark as charcoal, so they’re hard to spot.
3D-printing space parts — Lockheed Martin has finished quality control tests for its largest 3D-printed space part to date: an enormous titanium dome meant to serve as caps for satellite fuel tanks. The component measures 1.22 metres (4 feet) in diameter.
Robots that paint — CloudPainter creates evocative portraits featuring varying degrees of abstraction. One of its images was created by a team of neural networks, AI algorithms, and robots. Robotart’s founder, Andrew Conru, told MIT Technology Review that this year’s entries have shown refined brushstrokes and composition.
~ Yes, it’s really in how you read ‘Robotart’…
Rolls-Royce ‘cockroach’ robots — Rolls-Royce has announced it is teaming up with robotics experts at Harvard University and the University of Nottingham to develop tiny ‘cockroach’ robots that can crawl inside aircraft engines to spot and fix problems. These robots will be able to speed up inspections and eliminate the need to remove an engine from an aircraft for repair work to take place. The next step is to mount cameras on the robots and scale them down to a 15-milimetre size.
~ Yes, but will they spread pestilence? No! No real cockroaches will keep their jobs.
WWII-era Time Capsule requires internet sleuths’ help — Do you know WWII veteran Richard Silagy or his family? Silagy lived in Cleveland, Ohio, sometime after World War II and hid a time capsule filled with personal items in his home. The time capsule was discovered underneath stairs in the basement of the house, and includes photos, yearbooks, his hat from World War II, and even a munitions shell dated 1944 that looks as though it was fired.
The time capsule was recently discovered by a housing contractor doing improvements on the house, but a search online for Silagy or any living relatives has been a failure so the contractor is turning to the public for help.
~ I don’t know him.
Traces of lost society found in ‘pristine’ cloud forest — Deep in Ecuador’s lush Quijos Valley, a society thrived, then disappeared. But a lake preserved its story. In the 1850s, a team of botanists venturing into the cloud forest in the Quijos Valley of eastern Ecuador hacked their way through vegetation so thick they could barely make their way forward. This, they thought, was the heart of the pristine forest, a place where people had never gone. But they were very wrong. Indigenous Quijo groups had developed sophisticated agricultural settlements across the region, settlements that had been decimated with the arrival of Spanish explorers in the 1500s. In their absence, the forest sprung back. This process of societal collapse and forest reclamation is described in a new study published today in Nature Ecology and Evolution.
~ This shows the capacity of these forests to recover after they’ve been influenced by humans, which is a relief if you ask me.
