Researchers at the Indian Institute of Technology (IIT) Bombay and Shiv Nadar University claim to have developed a technology for production of environment friendly Lithium-Sulfur (Li-S) batteries which will be three times more energy efficient and cost effective than Lithium-ion batteries commonly used at present.
According to the team, the Li-S battery technology leverages principles of green chemistry, incorporating usage of by-products from the petroleum industry (Sulfur), agro-waste elements and copolymers such as cardanol (a by-product of cashew nut processing) and eugenol (clove oil) as cathodic materials.
The researchers said the technology has the potential to aid multi-billion dollar industries including tech gadgets, drones, electric vehicles (EV) and several more that depend on such batteries.
Lochab's team has partnered with Sagar Mitra, IIT Bombay's Professor in the Department of Energy Science and Engineering, to use the research for the development of a Li-S battery prototype.

ISRO's Chandrayaan 2 Identifies Craters that May have Water
Space agencies and private companies all over the world have their eyes set on the Moon as the next hub of human habitation. This includes the Indian Space Research Organisation (ISRO). It has found areas water could be right below the lunar surface, landing sites for future missions and what's hidden on the far side of the Moon over last one year.
The orbiter was successfully injected into orbit on August 20. The eight the eight instruments onboard have been scouting the lunar surface for information and clues that could set the stage for further moon exploration.
Even though the space agency did not share how much data was sent back to Earth, nearly half of it was from the Solar X-ray Monitor (XSM) and Chandrayaan-2 Large Area Soft X-ray Spectrometer (CLASS).
According to ISRO, the orbiter has enough fuel to continue its orbit around the Moon for another seven years. The data that it has collected so far will be made public by year-end.

Chandrayaan-2 Completes a Year Around Moon
Space agency ISRO said that India's second lunar mission Chandrayaan-2 completed one year in orbit around the moon on August 20 and all instruments are currently performing well and there is adequate onboard fuel to keep it operational for about seven more years. Chandrayaan-2 was launched on July 22, 2019 and inserted into the lunar orbit on August 20, exactly one year ago. The Indian Space Research Organisation said, 'Though the soft-landing attempt (of the lander carrying the rover) was not successful, the orbiter, which was equipped with eight scientific instruments, was successfully placed in the lunar orbit. The orbiter completed more than 4,400 orbits around the Moon and all the instruments are currently performing well.' The agency in a statement said the spacecraft was healthy and the performance of subsystems normal.

Astronomers Spot a Milky Way Look-alike Galaxy
Astronomers discovered the most distant look-alike galaxy of our Milky Way. The discovery was done with the help of Atacama Large Millimeter Array (ALMA Radio Telescope) located in the Atacama Desert of northern Chile. The extremely distant galaxy called SPT0418-47 is 12 billion light-years away from us. This means that the Milky Way galaxy look-alike that astronomers spotted was like this 12 billion years ago. On the other hand, the National Aeronautics and Space Administration (NASA) believes that our universe is around 13 billion years – give or take a few billion which makes the discovery more fascinating.
Astronomers were surprised to see SPT0418-47 have two similar features as our galaxy. They did not expect it to be organised enough to have disks and bulges. Instead, they expected it to have "turbulent and unstable" features. The SPT0418-47 has a rotating flat disk similar to our galaxy and a galactic bulge which shows a large group of stars in close proximity towards the centre.
This unexpected discovery challenges our understanding of how galaxies form, giving new insights into the past of our universe.

Chandrayaan-2 Captures Image of Crater on Moon
Chandryaan-2 has captured images of the Moon and one of the craters has been named after Vikram Sarabhai, the father of the Indian space programme.
As per Minister of State in the Prime Minister's Office Jitendra Singh, the recent achievements of the ISRO, which have placed India as a frontline nation of the world, is a vindication of Sarabhai's visionary dream.
The Department of Space directly comes under the Prime Minister's Office.
The Indian Space Research Organisation (ISRO) has sought to pay tribute to him in a special way by announcing that Chandrayaan-2 Orbiter has captured the Moon images of 'Sarabhai Crater.
The Sarabhai Crater is around 250 to 300 kilometres east of the crater where the Apollo 17 and Luna 21 Missions had landed.
