Other important points :-

  • James Webb Space Telescope is the largest and most powerful orbital observatory ever launched.
  • Cost of construction is $ 9 billion and it is an infrared telescope.
  • It was launched on December-25-2021 and reached its destination in solar orbit nearly 1 million miles from Earth a month later.

NEBULAE : The Hindu Analysis

  • It is a cluster of stars & gaseous clouds.
  • It is an interstellar cloud of dust, hydrogen, helium and other ionized gasses.
  • The dust and gasses in a nebula are spread out, but due to gravity it  begins to pull together and form clumps of dust and gas.  When these clumps get bigger and bigger, their gravity enhances. The Hindu Analysis
  • Eventually, these clump of dust and gas gets so big that it collapses from its own gravity and it causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.
  • The closest known nebula to Earth is called the Helix Nebula. It is approximately 700 light-years away from Earth.

JAMES WEBB SPACE TELESCOPE (JWST)  : The Hindu Analysis

  • JWST’s developed by joint collaboration of National Aeronautics and Space Administration (NASA),  European Space Agency (ESA) and the Canadian Space Agency (CSA).
  • It was launched in December 2021 on an Ariane 5 rocket from Kourou, French Guiana.  The Hindu Analysis
  • It reached orbit at the Sun-Earth L2 Lagrange point in January 2022.
  • It is designed primarily for near-infrared astronomy, but can also view orange & red visible light and mid-infrared region, depending on the instrument.
  • It is the most powerful infrared telescope.
  • It is also considered as the successor of the Hubble Telescope.
  • The telescope will study across the fields of astronomy & cosmology such as stars, formation of galaxies, exoplanets etc. The Hindu Analysis
  • Telescope is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 during the Mercury, Gemini, and Apollo programs.

 SOUTHERN RING NEBULA (SRN) : The Hindu Analysis

  • SRN also known as NGC 3132,  Eight-Burst Nebula, or Caldwell 74.
  • It is a bright and extensively studied planetary nebula in the constellation Vela.
  • Its distance from Earth is estimated at about 613 pc. or 2,000 light-years.
