Developed by NASA, ESA and the Canadian Space Agency, the James Webb Space Telescope (JWST) will be the most expensive and advanced space telescope ever created.
The telescope can be said to be the sequel to the famous Hubble telescope that was launched in 1990.
If all goes according to plan, the super telescope will be launched from the space base in French Guiana on December 18.
Then it will head for its final destination: an orbit around the sun, about 1.5 million kilometers from Earth.
And the hopes are high.
There are four scientific goals that researchers hope to achieve:
Look for light from the universe's first stars and galaxies
Study the formation and evolution of galaxies
Understand the formation of stars
Study planets and the origin of life
Maybe even can answer the question of whether we are alone in the universe or not
Using the telescope, scientists hope to study planets orbiting stars other than the sun.
This increases the possibility of finding planets that are similar to Earth - and perhaps getting answers to the question of whether there are signs of life elsewhere in the universe.
What makes the James Webb telescope unique is, among other things, the ability to see infrared light. Hear researchers explain how it works and what answers they hope the new telescope will provide in the video above.
