A group of astronomers from around the world has announced the discovery of an exceptionally metal-poor star. They made this breakthrough using the Gemini High-resolution Optical SpecTrograph (GHOST) at the Gemini South telescope in Chile, as detailed in their research paper published on the arXiv pre-print server on October 25.
Innovative Frequency Comb Enables Molecular Identification in 20-Nanosecond Intervals
Laser systems, referred to as frequency combs, offer the remarkable ability to pinpoint individual molecules, ranging from the straightforward carbon dioxide to intricate structures like monoclonal antibodies, with unparalleled precision and sensitivity. Despite their remarkable capabilities, frequency combs have faced constraints in keeping pace with rapid processes, such as hypersonic propulsion or the intricate process of proteins attaining their final three-dimensional configurations.
