NASA’s retired Space Shuttle Endeavour was carefully hoisted late Monday to be mated to a huge external fuel tank and its two solid rocket boosters at a Los Angeles museum where it will be uniquely displayed as if it is about to blast off. …read more […]
Not only does this discovery change everything we thought we knew about Astronomy in ancient times, but the ancient tablets describe math that was believed to have been invented over 1,000 years later, drastically changing everything we know about ancient man, and rewriting history books along the way.
For the past couple of decades, it was believed that ancient Babylonian astronomers used arithmetic systems for predicting the positions of celestial bodies. But …read more […]
Optical fiber, as the basic carrier of modern high-speed and high-capacity communication, is the key to the interconnection of the world. With the rapid development of the communications industry in recent decades, ordinary single-mode optical fiber can no longer meet the special needs of various industrial applications, so a series of optical fibers with complex internal structures, such as polarization-maintaining fibers, multi-core fibers and photonic crystal fibers, and other specialty optical fibers came into being in the civil and military fields are indispensable. …read more […]
The next generation of advanced telescopes could sharpen the hunt for potential extraterrestrial life by closely scrutinizing the atmospheres of nearby exoplanets, new research suggests. …read more […]
ESA plans to launch its FLEX mission in 2025. The aim is to collect data on the Earth’s vegetation from space. For the spectrometer on board the satellite, researchers from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena have developed and manufactured a double-slit assembly with exceptional accuracy as well as two high-precision mirrors. The double slit will be presented at SPIE Photonics West in San Francisco from January 30 to February 1. …read more […]
When light encounters a particle, it interacts with the particle instead of just passing through smoothly. The light waves can get scattered in different directions because of the light-matter interactions. …read more […]
With the upgraded GRAVITY-instrument at the Very Large Telescope Interferometer of the European Southern Observatory, a team of astronomers led by the Max Planck Institute for Extraterrestrial Physics has determined the mass of a black hole in a galaxy only 2 billion years after the Big Bang. With 300 million solar masses, the black hole is actually under-massive compared to the mass of its host galaxy. Researchers suspect what is happening here. …read more […]
Biofilms—slimy layers formed when bacteria stick together on a surface—allow bacteria to shield themselves from extreme environments and even evade antibiotics. In a new study, researchers have shown that laser light in the form of optical traps can be used to control biofilm formation. The findings could allow scientists to harness these microbial layers for various bioengineering applications. …read more […]
As part of the Artemis Program, NASA intends to establish all the necessary infrastructure to create a “sustained program of lunar exploration and development.” This includes the Lunar Gateway, an orbiting habitat that will enable regular trips to and from the surface, and the Artemis Base Camp, which will permit astronauts to remain there for up to two months. …read more […]
Teams with NASA’s Exploration Ground Systems Program began installing the four emergency egress baskets at Launch Pad 39B in preparation for NASA’s Artemis II crewed mission at the agency’s Kennedy Space Center in Florida. …read more […]
We do not yet know how, where, or why life first appeared on our planet. Part of the difficulty is that “life” has no strict, universally agreed-upon definition. …read more […]
Rice University scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place. …read more […]
Lieutenant David McShane died as the result of cancer that he developed following his assignment to the search and recovery efforts at the World Trade Center site following the 9/11… …read more […]
Our planet sits in the habitable zone of our sun, the special place where water can be liquid on the surface of a world. But that’s not the only thing special about us: we also sit in the galactic habitable zone, the region within the Milky Way where the rate of star formation is just right. …read more […]
