Optical imaging enters sub-nanometer era

Prof. Dong Zhenchao and Prof. Hou Jianguo from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) have improved the spatial resolution from 8 nm to ~8 Å of photoluminescence ...

NASA gathers nighttime images of Laura becoming a Hurricane

Tropical Storm Laura strengthened to a hurricane in the morning hours of Aug. 25, and NASA provided infrared imagery that showed the structure, temperature and rainmaking capabilities of the storm. When NASA's Terra satellite ...

NASA tracking Tropical Storm Laura near Cuba

As Tropical Storm Laura continues to move through the Caribbean Sea NASA satellites are providing forecasters with visible, infrared and microwave data. Laura continued to move through the Caribbean Sea on a march toward ...

Lensless light-field imaging through diffuser encoding

Microlens array based light-field imaging generally suffers from an intrinsic trade-off between the spatial and angular resolutions. To this end, scientists in China and German jointly proposed a lensless light-field imaging ...

New large optically bright supernova remnant discovered

Astronomers have reported the discovery of a new galactic supernova remnant (SNR) in the Cepheus constellation. The newly detected SNR is relatively large and optically bright, but faint in radio and X-ray bands. The finding ...
