(a) ISRO
(b) ESA
(c) NASA
(d) JAXA
Answer: (c)
Related facts:

  • TEMPLATES, stands for Targeting Extremely Magnified Panchromatic Lensed Arcs and their Extended Star Formation, a programme of NASA.
  • Using NASA’s James Webb Space Telescope as a sort of time machine, researchers plans to investigate how new stars are born.
  • Above programme will set up a template for future studies. For this, they will take the help of a natural phenomenon called gravitational lensing.
  • The phenomenon occurs when a huge amount of matter, such as a massive galaxy or cluster of galaxies, creates a gravitational field that distorts and magnifies the light from objects behind it, but in the same line of sight.
  • In effect, these are natural, cosmic telescopes; they are called gravitational lenses. These large celestial objects will magnify the light from distant galaxies that are at or near the peak of star formation.
  • The effect allows studying the details of early galaxies too far away to be seen otherwise with even most powerful space telescopes.
