NASA has developed and launched a new telescope, known as the James Webb Space Telescope which will be able to see the universe back to 13.8 Billion Years. It's the world's biggest and the most powerful telescope now. But how does it work? Is this a live example of Time Travelling? I talk about all these things in this video and also compare it to the Hubble Space Telescope by NASA, which was to date the most powerful telescope in the world.
