The latest Swedish-led search for technosignatures in the form of Dyson spheres has again come up empty-handed. The two latest stellar candidates in the hunt for such hypothetical extraterrestrial technology have been eliminated ...
Water stored in dams and reservoirs for humans to use often evaporates, especially in hot regions like southern Africa. Rising temperatures speed up evaporation, leaving less water for people, farming and industry. Daniel ...
The Roman Space Telescope is designed to directly image exoplanets using complex optomechanical systems developed by the Max Planck Institute for Astronomy
Microplastics are turning up almost everywhere—from oceans and rivers to soils and sediments—yet far less is known about what happens when they enter freshwater wetlands. Often overlooked in favor of marine and coastal environments, ...
For decades, light has been used to understand the molecular structures of matter. A sample is irradiated with light, and measurements determine the wavelengths at which it is absorbed. Since each molecule absorbs light at ...
Detecting short-wave infrared (SWIR) light, a region of the electromagnetic spectrum just beyond the light visible to the human eye, could be advantageous for many real-world applications. For instance, it could enable more ...
Researchers from Skoltech and their colleagues from Harbin Institute of Technology in China and ITMO University in Russia have devised a way to deposit elaborate geometric patterns of carbon nanotubes without wasting material. ...
Planets form from disks of gas and dust around young stars, but the gas needed for growth does not last forever. New observations from NASA's James Webb Space Telescope (JWST) now offer a new view of how this gas escapes ...
A NASA-led team hopes to take a shortcut to direct imaging of extrasolar Earth-like planets. The idea is to use what they call a hybrid telescope composed of an orbital starshade coupled with the next-generation extremely ...
A research team from Singapore, led by Associate Professor Dawn Tan of the Singapore University of Technology and Design (SUTD) and Dr. Luo Xianshu, head of the Silicon Photonics Department at the A*STAR Institute of Microelectronics ...
