JWST (James Webb Space Telescope) will be the largest, most powerful and complex space telescope ever built and launched into space. Basically this is the biggest, baddest telescope to have ever been built.
The planning for the JWST already started in 1996, and is planned for launch in October 31 2021. I for one is extremely excited for this. I mean it looks like a damn space ship itself and it will teach us so much more about space too.
But what’s the difference between the JWST and Hubble?
“Hubble is in a very close orbit around the Earth, while JWST will be 1.5 million kilometres away.”
Astrophysicist Blake Bullock, who is a director at Northrop Grumman Aerospace Systems explianed
“Hubble, when pushed to its maximum, could see galaxies that were teenagers in terms of age. We want to see babies. With the Webb (JWST), we will be able to see back in time to the earliest objects in the universe for the first time. Also for the first time, we will be able to characterize other planets going around other stars, distant exoplanets, and see if there are oceans, an atmosphere, what chemical elements are there.”
JWST has a much bigger mirror than Hubble and also has a sun shield the size of a tennis court that basically acts as a huge umbrella to keep it cool.
“Webb will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe”
