Light section system (100) for measurement of an object within a light area. The system comprises an ultraviolet light source (110), an optical system (120) suited for UV wavelengths that produces a section (180) in the light space on any objects (190) in the area and a detector (130...

In addition, their similar formation distance from the Sun suggested that KBOs should experience a similar evolution. Specifically, the irradiation of surface CH4 ice by solar ultraviolet light and solar wind particles should have converted some surface CH4 ice into red, complex, organic molecules. ...
mugs, phone cases, or cars. But the researchers are working toward flexible, programmable textiles. "We're looking at methods to dye fabrics and potentially use light-emitting fibers," says Wessely. "So, we could have clothing—t-shirtsand shoes and all that stuff—that can reprogram itself...
Debris proliferation is of special concern: we calculate that all log-decades in debris size contribute approximately the same amount of night sky radiance, so debris-generating events are expected to lead to a rapid rise in night sky brightness along with serious collision risks for satellites ...

“During the chip production process, it would be beneficial for manufacturers to use tiny sources of extreme-ultraviolet light to monitor this process in real time to diagnose any problems early on. That way, manufacturers could save resources and time on bad batches of chips, thereby increasing...
