Nasa's James Webb Space Telescope could give us a glimpse of first galaxies ever created

Nasa is preparing to launch the James Webb Space Telescope on 22 December that they hope will help them discover some of the earliest galaxies ever created, as well as finding new exoplanets that could harbour alien life.

The James Webb Space Telescope is the most powerful of its kind and will be capable of “sniffing” the atmospheres of distant planets to assess how suitable they would be for human life or otherwise.
