Atomic Hydrogen and GMRT

Why in News? The Giant Metrewave Radio Telescope (GMRT), which is located in Pune, has detected a radio signal originating from an extremely distant galaxy.


  • Atomic hydrogen is the basic fuel required for star formation in a galaxy.
  • When hot ionised gas from the surrounding medium of a galaxy falls onto the universe, the gas cools and forms atomic hydrogen.
  • This atomic hydrogen then becomes molecular hydrogen and eventually leads to the formation of stars.
  • Atomic hydrogen emits radio waves of 21 cm wavelength, which helps in the direct tracing of the atomic gas content in nearby and distant galaxies.

Giant Metrewave Radio Telescope (GMRT)

  • It is a low-frequency radio telescope that helps investigate various radio astrophysical problems ranging from nearby solar systems to the edge of the observable universe.
  • It is operated by the National Centre for Radio Astrophysics (NCRA), a part of the Tata Institute of Fundamental Research, Mumbai.


UNSC 1267 Committee

Why in News? The United Nations Security Council (UNSC) 1267 Committee has listed Abdul Rehman Makki as a global terrorist.


  • It is one of the most important and active UN subsidiary bodies working on efforts to combat terrorism, particularly in relation to Al Qaeda and the Islamic State group.

Living Will

Why in News? The Supreme Court agreed to modify its 2018 guidelines on “living will”, an advance medical directive on end-of-life treatment.


  • A living will is a concept associated with passive euthanasia.
  • It is a legal document which allows you to express your wishes to doctors in case you become incapacitated.
  • In a living will, you can outline whether or not you want your life to be artificially prolonged in the event of a devastating illness or injury.

Complications with ‘living will’:

  • Legal – An earlier verdict from the judiciary has noted that right to life under Article 21 does not include the right to die. Allowing making a living will would contravene this legal stand.
  • Rights – Allowing it would also acknowledge the patient’s autonomy and self-determination to the point of legalising a wish to die.
  • Social –There are chances of misusing the provision and leading to the abuse and neglect of the elderly.

Solitary Waves

Why in News? Recently, scientists have reported the first evidence of the presence of solitary waves or distinct electric field fluctuations in the Martian magnetosphere.


  • Solitary waves are the distinct electric field fluctuations (bipolar or monopolar) that follow constant amplitude-phase relations.
  • Their shape and size are less affected during their propagation.
  • Solitary waves have been found to play a significant role in the dynamics of various physical systems, such as in the Earth’s magnetosphere and in the Martian magnetosphere.
