China's Chang'e 5 Lunar Probe Finds First on-site Evidence of Water on Moon's Surface

  • China's Chang'e 5 lunar lander found the first-ever on-site evidence of water on the surface of the moon, lending new evidence to the dryness of the satellite.
  • The study revealed that the lunar soil at the landing site contains less than 120 parts-per-million (ppm) water or 120 grams water per ton, and a light, vesicular rock carries 180 ppm, which are much drier than that on Earth.
  • The presence of water had been confirmed by remote observation but the lander has now detected signs of water in rocks and soil.
  • A device on-board the lunar lander measured the spectral reflectance of the regolith and the rock and detected water on the spot for the first time.

China's $1 Trillion 'Artificial Sun' Fusion Reactor Just Got Five Times Hotter than the Sun

  • China's "artificial sun" set a new world record after superheating a loop of plasma to temperatures five times hotter than the sun for more than 17 minutes.
  • The EAST (Experimental Advanced Superconducting Tokamak) nuclear fusion reactor maintained a temperature of 158 million degrees Fahrenheit (70 million degrees Celsius) for 1,056 seconds. The achievement brings scientists a small yet significant step closer to the creation of a source of near-unlimited clean energy.

BMW Unveils Car that Changes Colour

  • BMW unveiled a chameleon car that changes colour, in the latest attempt by automotive firms to combine their vehicles with cutting-edge technology.
  • At the touch of a button, a driver can change the shade of the car's exterior, allowing the colour to shift between black and white or even light and dark stripes by activating electronic ink in the wraparound shell.
  • According to BMW, the effect is created by applying an electrical charge to microcapsules – which contain particles of white and black pigments – suspended within a liquid encased in the wrap. The colour alternates depending on whether a negative or positive charge is applied, causing either the white or the black pigments to collect at the surface of the microcapsule.

Technicians Successfully Deploy James Webb Telescope Giant Sunshield

  • NASA technicians successfully fully deployed the massive sunshield protecting the James Webb Space Telescope.
  • The sunshield - about the size of a tennis court at full size - was folded to fit inside the payload area of an Arianespace Ariane 5 rocket's nose cone prior to launch. The Webb team began remotely deploying the sunshield on Decemebr 28, 2021, three days after launch.

TCL Electronics Announces its First Laptop 'TCL Book 14 Go'

  • Consumer electronics brand TCL officially announced its first laptop 'TCL Book 14 Go' offering a Snapdragon 7c chipset and Windows 11 support.
  • The TCL Book 14 Go is priced at $349 and it is expected to be available for purchase in Q2, 2022. At the moment, there are no details on its sale dates in different regions, reports GizmoChina.
  • In terms of specifications, the TCL Book 14 Go sports a 14.1-inch display with a resolution of 1366 x 268 pixels resolution.

Using ALMA Scientists Discover Newborn Star

  • Using the Atacama Large Millimeter/submillimeter Array (ALMA), scientists have detected a newborn star and the surrounding cocoon of a complex organic matter, for the first time.
  • The discovery revealed the hidden chemical complexity of Universe.
  • The scientists used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile for observing a newborn star (protostar) in WB89-789 region. It is located in extreme outer Galaxy.
  • They also detected a variety of carbon-, oxygen-, sulfur-, nitrogen-, and silicon-bearing molecules, including complex organic molecules comprising up to nine atoms.
  • Observations reveal that, several types of complex organic molecules, like methanol (CH3OH), methyl formate (HCOOCH3), ethanol (C2H5OH), dimethyl ether (CH3OCH3), propanenitrile (C2H5CN), formamide (NH2CHO), etc., are present in primordial environment of the Galaxy.
  • ALMA is an astronomical interferometer comprising of 66 radio telescopes in Atacama Desert of northern Chile. The array observes electromagnetic radiation at wavelengths of millimeter and submillimeter. Array has been constructed at the elevation of 5,000 m in Chajnantor plateau. This location was selected for its high elevation and low humidity, which are essential factors for reducing noise and decrease signal attenuation due to atmosphere of Earth.
  • ALMA is an international partnership between Europe, the United States, Japan, Canada, Taiwan, South Korea and Chile.
