The constellations of satellites that swarm Earth’s orbital skies are currently polluting wavelength bands that should be protected for radio astronomy. Electronics aboard SpaceX’s Starlink satellites “leak” low-frequency radio waves, separated from their allotted downlink bands, in a way that could impact our ability to perform astronomy, according to new research. “This study represents the … Read more
RIKEN researchers have developed a portable device that effectively uses the terahertz band of the electromagnetic spectrum for radiography of objects without harmful radiation. By optimizing certain techniques and using specific materials, they greatly improved the power of terahertz waves and miniaturized the device. The technology holds promise for various applications including non-destructive imaging and … Read more
An artist’s illustration of the Starlink satellites above the LOFAR array. The hum of onboard electronics that power SpaceX’s Starlink satellites could be disrupting radio astronomy observations, according to a new study. Experts have long warned about how astronomy suffers from megaconstellations of satellites in low Earth orbit such as SpaceX‘S Stellar connection. The stripes … Read more
