1. NASA will study the formation of new stars under a program called Targeting Extremely Magnified Panchromatic Lensed Arcs and Their Extended Star Formation, or TEMPLATES.
  2. The program has four main goals: a) Measure how many new stars are forming, to determine how rapidly galaxies form stars, b) Map the star-formation rate in four selected galaxies, c) Compare the young and old stellar populations and d) Measure the conditions of the gas within these galaxies
  3. The study will be conducted using NASA’s James Webb Space Telescope. Scientists would take help of a natural phenomenon call gravitational lensing which would magnify the light from distant galaxies that are at or near the peak of star formation.
  4. Gravitational lenses are considered to be natural, cosmic telescopes. 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.
  5. The effect allows researchers to study the details of early galaxies too far away to be seen otherwise with even the most powerful space telescopes.
