official news from : https://bit.ly/2QkyIbY This Oct. 4, 2017, illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian’s Star or Tabby’s Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler but longer-term dimming trends. Scientists proposed several explanations forContinue reading “Ring Around Tabby’s Star”

official news from : https://bit.ly/2QkyIbY NASA supercomputers are shedding light on what causes some of the Sun’s most complex behaviors. Using data from the suite of active Sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar dynamics like never before.  The animation shows the strength of the turbulent motionsContinue reading “Ready, Set, Action!

official news from : https://bit.ly/2QkyIbY In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our Sun. Unlike an exploding star though, it has declined inContinue reading “NASA’s Hubble Finds Sizzling Details About Young Star FU Orionis”

official news from : https://bit.ly/2QkyIbY The mystery of why life uses molecules with specific orientations has deepened with a NASA-funded discovery that RNA — a key molecule thought to have potentially held the instructions for life before DNA emerged — can favor making the building blocks of proteins in either the left-hand or the right-handContinue reading “NASA: Mystery of Life’s Handedness Deepens”

official news from : https://bit.ly/2QkyIbY ESI24 Li Quadchart Wei LiUniversity of Texas at Dallas Internal defects are always formed in laser welding process due to the keyhole instability, molten pool collapse, and rapid solidification. The extreme lunar environment complicates the reliable implementation of welding, thereby enhancing the welding defects formation. The welding defects are critical materialContinue reading “Integrated Computational Materials Modelling Framework for Investigating the Process-Structure-Property Linkage of the Lunar Metal Welding with Internal Defects”

official news from : https://bit.ly/2QkyIbY ESI24 Nam Quadchart SungWoo NamUniversity of California, Irvine Lunar dust may seem unimposing, but it presents a significant challenge for space missions. Its abrasive and jagged particles can damage equipment, clog devices, and even pose health risks to astronauts. This project addresses such issues by developing advanced coatings composed of crumpledContinue reading “Deformable Crumpled Nano-ball Coatings with Adaptable Adhesion and Mechanical Energy Absorption for Lunar Dust Mitigation”

One significant challenge observed during the Apollo missions was the adhesion of lunar dust, which can build up on vehicle, equipment, and space suit. HighlyContinue reading “Engineering the Adhesion Mechanisms of Hierarchical Dust-Mitigating Nanostructures”

official news from : https://bit.ly/2QkyIbY ESI24 Haghighi Quadchart Azadeh HaghighiUniversity of Illinois, Chicago In-space manufacturing and assembly are vital to NASA’s long-term exploration goals, especially for the Moon and Mars missions. Deploying welding technology in space enables the assembly and repair of structures, reducing logistical burdens and supply needs from Earth.
