Will James Webb Space Telescope see big bang?
The James Webb Space Telescope (Webb) is the next great space science observatory following Hubble, designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy.
Webb will see farther into our origins: from the formation of stars and planets, to the birth of the first galaxies in the early Universe. Webb is an international partnership between NASA, ESA and CSA. The telescope launched on an Ariane 5 from Europe's Spaceport in French Guiana.
Will James Webb space telescope see beginning of the universe?
COBE, WMAP, and Planck all saw further back than JWST, though it's true that JWST will see farther back than Hubble. JWST was designed not to see the beginnings of the universe, but to see a period of the universe's history that we have not seen yet before.
Specifically we want to see the first objects that formed as the universe cooled down after the Big Bang. That time period is perhaps hundreds of millions of years later than the one COBE, WMAP, and Planck were built to see.
We think that the tiny ripples of temperature they observed were the seeds that eventually grew into galaxies. We don't know exactly when the universe made the first stars and galaxies - or how for that matter. That is what we are building JWST to help answer.
So that's it for today's video!
