The lines of defence that cyanobacteria use against UVR. EPS—exopolysaccharides, CAT—catalase, SOD—superoxide dismutase, GR—glutathione reductase, Car—carotenoids, MAAs—mycosporine-like amino acids, and Scy—scytonemin. — International Journal of Molecular Sciences One of the
A collage of 32 glowing discs on a black background. Each disc shows concentric rings in vivid colours: purple, orange, and yellow, with bright cyan centres. The discs vary in
The Southwest Research Institute-led Ultraviolet Spectrograph (UVS) aboard NASA’s Europa Clipper spacecraft made valuable observations of the interstellar comet 3I/ATLAS during a period when it was difficult to observe from
Multi-color ground-based light curves for our five targets. Data points represent 10-minute binned photometry, with light curves obtained using identical filters and exposure times phase-folded together. Black curves show the
HD 131488 Disk and Slit Alignment, showcasing our data is sensitive to the disk region inward of 30 AU to the star. Left: The JWST NIRSpec Slit is overlaid on
In 2024, astronomers discovered the brightest Luminous Fast Blue Optical Transient (LFBOT) ever observed. LFBOTs are extremely bright flashes of blue light that shine for brief periods before fading away.
In a glimpse of the early universe, astronomers have observed a galaxy as it appeared just 800 million years after the Big Bang – a cosmic Jekyll and Hyde that
WASHINGTON — HawkEye 360, a U.S. commercial satellite company that tracks radio-frequency signals from orbit, announced Dec. 18 it has acquired defense contractor Innovative Signal Analysis, deepening its push into
