They are the strongest lasers in history, and their beams are helping scientists explore the structure of the universe.In a research laboratory at the University of Michigan, bright green light fills the vacuum chamber of a technology giant. It is the size of two tennis courts. The walls are shielded with 60 centimeters of concrete to prevent radiation leakage, and workers wear masks and hairnets ...
Compared to Impressionist paintings taken 50 years ago, upon closer inspection of Impressionist paintings in museums, you may notice some strange things: some are losing their bright yellow hue.Taking the dramatic sunset in Edward Munch's masterpiece "The Scream" as an example. The once bright orange yellow parts of the sky have faded to off white.Similarly, in his painting "The Joy of Life", Henr...
Energy conversion technology is an important research direction in modern science and engineering. Scientists are exploring new catalytic chemical methods to achieve the conversion of energy chemicals, such as photocatalysis and electrocatalysis. However, these highly anticipated catalytic chemistry technologies still have some problems in practical applications, and there is still a certain dista...
Recently, NASA's official website showed that a research team at the University of Central Florida has tested an instrument called Ejecta STORM, which aims to measure the size and velocity of surface particles generated by exhaust gases from rocket powered landers on the moon or Mars.According to NASA, when a spacecraft lands on the moon or Mars, rocket exhaust plumes can produce efflorescent ejec...
TNO wrote that this is the first time Dutch technology has been used to send data from a satellite to a ground station press release on Earth. This technology uses invisible laser signals to achieve faster and safer data flow compared to ubiquitous communication radio frequencies.Kees Buijsrogge, Director of TNO Space, said, "This critical milestone marks a significant achievement for the Netherla...
