SpaceX and its billionaire CEO Elon Musk may finally have reason to look back in the satellite internet competition. On Thursday, Amazon revealed that it had successfully used a space laser technology called "Optical Intersatellite Link" to transmit connections between two Kuiper Program satellites in low Earth orbit, located 621 miles apart, at a speed of 100 gigabits per second. This is approxim...

Two photon polymerization is a potential method for nanofabrication of integrated nanomaterials based on femtosecond laser technology. The challenges faced in the field of 3D nanoprinting include slow layer by layer printing speed and limited material selection due to laser material interactions.In a new report in Progress in Science, Chenqi Yi and a team of scientists in the fields of technical s...
A powerful telescope in South Africa has detected a space laser 5 billion light-years away from Earth, known as the "megamaser". Scientists named it Nkalakatha, which means "big boss" in Zulu language.Nkalakatha is the farthest hydroxyl giant detected so far, discovered by the MeerKAT telescope on the first night of the survey, which is expected to include 3000 hours of observation. The team of sc...
When it comes to additive manufacturing, some people may not have heard of it, but when it comes to its other name: 3D printing, no one is unaware.In fact, the name 'additive manufacturing' better illustrates the essence of this processing method. From ancient times to the present, humans have put in great effort to achieve the goal of processing 'raw materials into the shapes we need'. From the S...
