The $10 billion space project will be able to look back further than any other space telescope that has come before it. The James Webb is the most ambitious space telescope ever built that will help to revolutionize how we see the universe. It has taken 25 years to build the telescope as scientists said it had decades of delay and a lot more expenses.
The James Webb telescope is said to be 100 times more powerful than the Hubble. The Hubble’s mirror has a diameter of 2.4 metres and Webb’s has a diameter of 5.6 metres. Scientists consider the James Webb Telescope to be the successor to the Hubble since it was inspired by the Hubble’s results.
The light from everything in the sky takes time to travel to Earth for us to see. The moon’s light takes approximately just over one second to reach Earth, and the sun’s light takes roughly eight minutes. So, the further the object from our planet, the longer its light will take to reach us. What this means is that when we look at distant stars and galaxies, we’re looking back in time.
