DETAILS
Morning of 1st September was pretty hot but in the afternoon it rained heavily till 4 PM.
Sept. 1, 2020: Infrared spectroscopy is especially important in the world of chemistry, where it is used to analyze and identify molecules. The current state-of-the-art method can make approximately 1 million observations per second. University of Tokyo researchers have greatly surpassed this figure with a new method about 100 times faster. More recently, a technique called dual-comb spectroscopy achieved a measurement rate of 1 million spectra per second. However, in many instances, more rapid observations are required in order to produce fine-grain data, It could be revealing an unknown process in neutron decay.

Sept. 2, 2020: The National Aeronautics and Space Administration (NASA) on Wednesday congratulated Indian astronomers on the discovery of one of the farthest Star galaxies in the universe estimated to be located 9.3 billion light-years away from Earth. NASA congratulates researchers on their exciting discovery. India’s AstroSat/UVIT was able to achieve this unique feat because the background noise in the UVIT detector is much less than one on the Hubble Space Telescope of US-based NASA. The galaxy called AUDFs01 was discovered by a team of astronomers.
Sept. 2, 2020: Russia tested Tsar Bomba over a remote archipelago in the Arctic Ocean on October 30, 1961 — during the height of a nuclear arms race with the US. The country declassified documentary footage of that explosion on August 20, a blast equivalent to 50 megatons of TNT. Russia reported that the flash could be seen from more than 600 miles away. When the weapon is released from the plane, a parachute helps it drift to the desired elevation: 13,000 feet above ground. That gives the plane enough time to fly a safe distance away. At 22:44 in the video, the bomb explodes. The footage shows a burst of light, followed by a giant orange fireball and mushroom cloud.
Sept. 2, 2020: 4.1 magnitude earthquake in Gujarat’s Kutch district, on Wednesday afternoon. The quake was recorded at 2.09 pm with its epicentre 7 km north-north east from Dudhai. The depth of the light-intensity quake was 30.5 km. Earlier in the morning, a mild quake of 2.3 magnitude was recorded with its epicentre 19 km east-north east from Lalpur in Jamnagar district of Saurashtra region.
Sept. 2, 2020 Strong rains hit southern Japan as Koreas ready for typhoon. High waves crash a shore as Typhoon Maysak approach on Jeju Island, South Korea. An offshore typhoon brought torrents of rain to southern Japan on Wednesday as it headed to the Korean Peninsula, while another storm in the Pacific grew stronger.
Sept. 2 2020: Electromagnetic chirality: From fundamentals to nontraditional chiroptical phenomena. Recent advancements in artificial nano-materials and structured optical fields have expanded the concept of chiroptical phenomena. However, chiroptical phenomena originate from complicated processes involving transitions between states with opposite parities, so fundamentals of chiroptical processes are required for solid interpretation the phenomena.
Sept. 3 2020: 7:27 AM EDT: More than 40 crew missing after cattle ship capsizes in storm off Japan and an Australian presumably died.
Sept. 3, 2020: 100 million-year-old meteorite crater found in Western Australia.
Sept. 04, 2020: The mystery of the neutron lifetime. Over the course of about 15 minutes, it breaks apart into a proton, an electron, and a tiny particle called an anti-neutrino. But how long the neutron takes to fall apart presents a bit of a mystery. One method measures it as 887.7 seconds, plus or minus 2.2 seconds. Another method measures it as 878.5 seconds, plus or minus 0.8 second. At first, this difference seemed to be a matter of measurement sensitivity. It may be just that. But as scientists continue to perform a series of ever-more-precise experiments to evaluate possible issues, the discrepancy remains. This persistence leads to the possibility that the difference is pointing to some type of unknown physics. It could be revealing an unknown process in neutron decay. Or it could be pointing to science beyond the Standard Model scientists currently use to explain all of particle physics.
Sept. 4, 2020: Arctic sea-ice loss intensifies aerosol transport to Tibetan Plateau.
Sept. 4, 2020: Quantum states induced by single-atomic impurities are at the frontier of physics and material science. While such states have been reported in high-temperature superconductors and dilute magnetic semiconductors, they are unexplored in topological magnets which can feature spin-orbit tenability. Here we use spin-polarized scanning tunneling microscopy/spectroscopy (STM/S) to study the engineered quantum impurity in a topological magnet Co3Sn2S2. We find that each substituted In impurity introduces a striking localized bound state. Our systematic magnetization-polarized probe reveals that this bound state is spin-down polarized, in lock with a negative orbital magnetization. Moreover, the magnetic bound states of neighboring impurities interact to form quantized orbitals, exhibiting an intriguing spin-orbit splitting, analogous to the splitting of the topological fermion line. Our work collectively demonstrates the strong spin-orbit effect of the single-atomic impurity at the quantum level, suggesting that a nonmagnetic impurity can introduce spin-orbit coupled magnetic resonance in topological magnets.

Sept 06, 2020: Triple star system found with weirdly warped planetary disc. Now, astronomers have observed a triple star system that’s warping and splitting its planetary disc into strange new shapes and multiple rings. multiple rings. Now, astronomers have observed a system where this flat disc is being bent out of shape. Known as GW Orionis, the system lies around 1,300 light-years from Earth and contains three stars orbiting each other. The researchers studied GW Orionis for over 11 years using different instruments on the Very Large Telescope (VLT) and ALMA to resolve the structure of the system, and backed it up with computer simulations of what was going on there. The team found that the two inner stars orbit each other at 1 Astronomical Unit (AU) apart – the same distance between Earth and the Sun. The third star orbits the other two from further out, at a distance of about 8 AU. The complex gravitational dance between these three stars has split the protoplanetary disc into three separate rings, each with their own orientation. The closest ring is the most out-of-whack, angled almost perpendicular to the rest of the disc. This inner ring contains enough dust to create the equivalent of 30 Earths. The second ring starts about 185 AU from the center of the system, while the third starts at a distance of 340 AU. That makes it the largest proto-planetary disc observed so far.
