09 August Current Affair For All Competition Exams

1. Indian telescope discovers most distant radio galaxy ever

  • Astronomers have used an Indian telescope to discover the most distant radio galaxy ever known, located at a distance of 12 billion light-years.
  • The galaxy from a time when the universe was only seven per cent of its current age was found using the Giant Meter-wave Radio Telescope (GMRT) in Pune.
  • GMRT is an array of thirty fully steerable parabolic radio telescopes of 45-metre diameter. It is operated by the National Centre for Radio Astrophysics.

Related Information

  • Radio galaxies are very rare objects in the universe.
  • They are colossal galaxies with a supermassive black hole in their centre that actively accretes gas and dust from its surroundings.
  • This activity initiates the launch of high-energy jet streams, which are capable of accelerating charged particles around the supermassive black hole to almost the speed of light.

2. Scrub typhus is key encephalitis cause in eastern U.P.

  • Scrub Typhus is an infectious disease which is transmitted by the bite of an infected mite larva present in the soil.
  • It is not caused by a virus, but by a parasite called Orientia tsutsugamushi.
  • Almost, 65% of the Acute Encephalitis Syndrome (AES) patients got infected by Scrub Typhus (Gorakhpur in U.P is treated as a hub of AES).
  • This disease is more common during monsoon season when the mites lay eggs.

3. New sensor developed to measure sea surface temperatures

  • Sea surface temperature (SST) is an important parameter for oceanographic and atmospheric studies and to monitor biological habitations in the marine environment.
  • Indian scientists have developed a new sensor to measure ocean temperatures.
  • The negative temperature coefficient (NTC) thermistor-based sensor, developed by scientists at the Chennai-based National Institute of Ocean Technology (NIOT) and School of Engineering at Vels University, Chennai, can be deployed on drifting buoys on the sea.
  • India has deployed buoys named Pradyu which communicate with Indian satellite INSAT for real-time data telemetry.
  • Twenty such buoys equipped with the new sensor have been deployed in the Arabian Sea from the research vessel, SagarManjusha.
  • They were used to collect sea surface temperature data for about one month.

4. ISRO developing eco-friendly propellants for its rockets.

  • The Indian Space Research Organization (ISRO) is developing green propellants for future rockets, considering the harmful effects of exhausts released by rockets on the earth’s atmosphere.
  • The propellants that are being used have a very reactive effect on the ozone layer due to the release of chlorinated exhaust products.
  • This, along with other chemicals released, wreaks havoc on the sensitive ozone layer.
  • The new propellant has the capacity to eliminate chlorinated exhaust from rocket motors. The solid propellant is based on Glycidyl Azide Polymer as fuel and Ammonium Di-Nitamide as an oxidiser.
  • ISRO has already been using LOX/Liquid Hydrogen and LOX/Kerosene-based propulsion systems for launch vehicles, and electric propulsion for spacecraft.
  • The LOX/Liquid Hydrogen combination is already being used in the upper stages of the Geosynchronous Satellite Launch Vehicle (GSLV) and GSLV Mk-III.

  • The most interesting part is that all the information is available at tariff line.
  • The app works internally to map the ITC HS code of other countries with that of India and provides all the required data without the users bothering about the HS code of any country.
  • Presently the app comes with the data from 87 countries.
  • Human Resource tool of the app enables candidates with interest in the international trade sector to register and apply against the vacancies arising in the sector.
  • Companies can also search the profiles of the candidates and engage them.
