About James Webb Space Telescope:
- It was launched in December 2021.
- It is the largest and most powerful space observatory built through collaboration between NASA, European Space Agency (ESA), and Canadian Space Agency (CSA).
- JWST orbits the L2 Lagrange Point, about 1.5 million km beyond Earth, enabling a stable position for deep-space observation.
- The telescope operates primarily in the infrared spectrum and is equipped with components such as:
- Optical Telescope Element (OTE): It collects light from distant objects.
- Integrated Science Instrument Module (ISIM): It houses all cameras and instruments.
- Sunshield: It protects sensitive instruments from solar radiation.
- Spacecraft Bus: It provides necessary operational support.
- Objectives of James Webb Space Telescope:
- To look for galaxies that formed just after the Big Bang.
- To determine the evolution of galaxies from their creation to the present.
- To examine the stages of star creation till the formation of planetary systems.
- To investigate the potential for life in planetary systems by measuring their physical and chemical features.
