James Webb Space Telescope News Highlights:

  • The world's largest and most powerful telescope to date was developed to aid in the study of the universe's early days and the unravelling of some of its greatest mysteries.
  • The European Space Agency , NASA has built the telescope .
  • The new telescope will aid scientists in their investigations into the structures and origins of our universe.

The $10 billion telescopes built by NASA The European Space Agency's Kourou, French Guiana, will launch the James Webb Space Telescope, which will catch the first view of the cosmos immediately after the Big Bang. In the coming decade, the revolutionary world's first-of-its-kind space-science observatory will catch the earliest galaxies thought to have formed during the early universe's birth. The new telescope will aid scientists in their investigations into the structures and origins of our universe, as well as our location within it.

The telescope's dimensions are as follows:

In terms of size and intricacy, the telescope is unparalleled. Its mirror is three times the size of Hubble's, measuring 6.5 meters (21 feet) in diameter and made up of 18 hexagonal parts. It was folded to fit into the rocket since it was so big.

Facts to Remember

  • Webb will be the main space observatory for scientists all over the world to continue the Hubble Space Telescope's findings.
  • It will be the largest telescope ever sent into space, with a 100-fold increase in power above Hubble.
  • The telescope will look back 13.5 billion years to see the first galaxies that appeared after the Big Bang.
  • With a total mass of 6200 kg, it will be the largest telescope ever launched into space.
  • They can discern features the size of a US dime at a distance of around 24 miles and detect the heat signature of a bumblebee at the distance of the moon (40 km).

Looking back to the origin

Because light takes time to travel through space, these telescopes are effectively time machines. This means that as Webb analyses light from the universe's farthest galaxies, it is actually looking at how the universe looked billions of years ago.
The Webb telescope is designed to "see" beyond the human eye's and other telescopes that only examine visible light. Webb's infrared vision can see past thick layers of cosmic gas and dust, allowing it to view astronomical objects that other telescopes might miss.
