Astronomers see black hole raging red
Violent red flashes, lasting just fractions of a second, have been observed during one of the brightest black hole outbursts in recent years. In June 2015, a black hole called V404 Cygni underwent dramatic brightening for about two weeks as it devoured material that it had stripped off an orbiting companion star.
In a new study, an international team of astronomers, led by the University of Southampton, report that the black hole emitted dazzling red flashes lasting just fractions of a second as it blasted out material that it could not swallow.
The astronomers associated the red color with fast-moving jets of matter that were ejected from close to the black hole. These observations provide new insights into the formation of such jets and extreme black hole phenomena.
NASA selects proposals to build better solar technologies for deep space missions
NASA’s Game Changing Development (GCD) program has selected four proposals to develop solar array technologies that will aid spacecraft in exploring destinations well beyond low-Earth orbit, including Mars.
NASA’s future deep space missions will require solar arrays that can operate in high-radiation and low-temperature environments. Developing a new generation of solar power technologies that focuses on these attributes will improve mission performance, increase solar array life, and ultimately may allow solar-powered vehicles to explore deeper into space than ever before.
Microchip shrinks radar cameras to fit into a palm
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a chip that allows new radar cameras to be made a hundred times smaller than current ones. With this NTU technology, radar cameras that usually weigh between 50 kg and 200 kg and are commonly used in large satellites can be made to become as small as palm-sized.
Despite being small, they can produce images that are of the same high quality if not better compared to conventional radar cameras. They are also 20 times cheaper to produce and consume at least 75 percent less power. Developed over the past three years at NTU, the promising technology has already secured S$2.5 million in research funding from Singapore government agencies.
