Record-breaking Light has more than a Quadrillion Electron Volts of Energy

  • Extremely energetic light from space is an unexplained wonder of astrophysics, and now scientists have spotted this light, called gamma ray, at higher energies than ever before.
  • The Large High Altitude Air Shower Observatory, LHAASO, spotted more than 530 gamma rays with energies above 0.1 quadrillion electron volts. The highest-energy gamma ray detected was about 1.4 quadrillion electron volts. For comparison, protons in the largest accelerator on Earth, the Large Hadron Collider, reach mere trillions of electron volts. Previously, the most energetic gamma ray known had just under a quadrillion electron volts.
  • In all, the scientists spotted 12 gamma ray hot spots, hinting that the Milky Way harbors powerful cosmic particle accelerators. In order for gamma rays to reach such energies, electromagnetic fields must first rev up charged particles, namely protons or electrons, to immense speeds. Those particles can then produce energetic gamma rays, for example, when protons interact with other matter in space.

China Observatory Detects Sources of Gamma Rays

  • Large High Altitude Air Shower Observatory (LHAASO) of China detected dozen sources of ultra-high-energy gamma rays.
  • LHAASO cosmic ray observatory has discovered 12 sources of ultrahigh-energy photons. It has also detected a photon with energy level of 1.4 peta-electron volt. All these sources are located at positions in milky way galaxy and it can be measured with an accuracy of greater than 0.3°. They are the brightest Milky Way gamma ray sources discovered till date.
  • LHAASO is a gamma-ray and cosmic-ray observatory located at Daocheng in Sichuan province of China. The observatory has been designed to observe air showers that are triggered by gamma rays and cosmic rays. It has been set at the altitude of 4,410 metres above sea level. It started observation in April 2019 over an area of 145 hectares.

Microsoft to Retire Iconic Internet Explorer Browser in 2022

  • Microsoft has announced to retire its iconic Internet Explorer (IE) browser in June 2022, as it envisions the future of Internet Explorer, which was launched in 1995, on Windows 10 in Microsoft Edge.
  • Over the last year, Microsoft is moving away from Internet Explorer support, such as an announcement of the end of IE support by Microsoft 365 online services.
  • With Microsoft Edge capable of assuming this responsibility and more, the Internet Explorer 11 desktop application will be retired and go out of support on June 15, 2022, for certain versions of Windows 10.
  • Internet Explorer was once the most widely used web browser, attaining a peak of about 95 per cent usage share by 2003.

Iran Develops its Most Powerful Supercomputer 'Simorgh'

  • Iran has unveiled a new supercomputer named 'Simorgh', which is 100 times more powerful than the previous supercomputer of the country to date. The supercomputer has been developed indigenously by Tehran's Amirkabir University of Technology (AUT). It has been named after a mythical Phoenix-like bird 'Simurgh'.

Atlas V Rocket Launches SBIRS Geo-5 Missile Warning Satellite for US Space Force

  • The United Launch Alliance launched the Atlas V rocket from Cape Canaveral Space Force Station, Florida. The Atlas V rocket carried SBRIS Geo-5 Missile Warning Satellite. The full form of SBRIS is the Space-Based Infrared System. It is designed for missile warning, missile battle space and defence characterisation.
  • SBRIS is basically a Space Tracking and Surveillance System. SBRIS was designed to meet the Infrared Space Surveillance of the United States Space Force System. In 2020 alone, the SBRIS satellites detected more than a thousand missiles.
  • The satellite will provide key capabilities in missile warning, battle space, missile defence. It weighs 4,850 kilograms. As of 2018, ten SBRIS satellites were launched.
  • Atlas V is a two-stage rocket. It is fuelled with rocket grade kerosene and liquid oxygen in its first stage and hydrogen and liquid oxygen in the second stage.
  • The rocket put SBRIS at a height of 35,753 km.
