James Webb Space Telescope Set For Launch - Christmas Day
Think of the James Webb ST as a time machine with infrared vision that will look back over 13.5 billion years to detect the first stars and galaxies, emerging from the darkness of an early universe.
(The universe is 13.8 billion years old; so, yes Horatio, that's looking way back!)
Still more exciting, the James Webb ST will also be searching for life on other planets. It will help scientists in identifying and measuring potential biosignatures in the exoplanets' atmospheres.
But first we have to launch it into space, and travel a million miles away. Unlike Hubble, if anything goes wrong, there is no second chance to make repairs. I am already holding my breath.
This project is 20 years in the making, so much at stake. But if successful, it will usher in a whole new era of science and discovery!
