Monitoring Webb"s mirrors for optimal optics
NASA's James Webb Space Telescope is the largest and most powerful telescope ever launched to space. Its mirror is composed of 18 individual segments that have been aligned so accurately, that they effectively work as a single giant (21.6-foot, or 6......»»
Paying attention to errors can improve fused remote monitoring of lakes, researchers say
Lakes can tip the scales from healthy to potential environmental hazard quickly when they become eutrophic. In this state, an abundance of nutrients accelerates algae growth, which then crowd the water's surface and block light from reaching organism.....»»
Astronomers detect black hole "starving" its host galaxy to death
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black holes can starve their host galaxies of the fuel they need to form new stars. The results are reported in the journal Nature Astronomy......»»
The skyscraper-sized tsunami that vibrated through the entire planet and no one saw
Earthquake scientists detected an unusual signal on monitoring stations used to detect seismic activity during September 2023. We saw it on sensors everywhere, from the Arctic to Antarctica......»»
