The World May See the Most Powerful Telescope in 2018

The Most Powerful Telescope!

Well, we never really wonder how powerful telescopes can be, do we? After all, we are never used to using them for things the scientists and the NASA does. However, despite telescopes not being something very important to us, features of the James Webb Space Telescope (JWST), the upcoming most powerful telescope of the world, which is expected to be launched in 2018, will still manage to surprise most of us.

The Size

The Current Most Powerful Telescope

The Hubble Space Telescope is currently the biggest telescope, which is being used by NASA to observe the space. However, NASA seems to be having much bigger plans now, as it plans to come up with something way more powerful than the Hubble Space Telescope. It will be something that the world never saw before, and may never see anything similar for a long time to come.

Why it’s Believed to be so Powerful?

Well, the things that we have mentioned above may have got you thinking about exactly what’s in this new upcoming telescope that would make it so very powerful. If you are someone who is feeling curious to know the answer, let us tell you that there are quite a few things.

First and foremost, and maybe one of the most surprising ones of all, the James Webb Space Telescope will be 100 times more powerful than the currently most powerful telescope, the Hubble Space Telescope. This is saying something, given that NASA has been using it as their primary and most powerful tool to observe the space from as long as around 25 years now. So the new one which NASA now plans to build has to be powerful beyond one’s imagination to be really be worthy of replacing the Hubble Space Telescope, which is already quite powerful.

However, the JWST is expected to have some other amazing features as well. The Hubble Space Telescope may be powerful, but it doesn’t allow one to see the first galaxies of the universe. The JWST, however, is expected to do that!

It is expected to be capable of allowing the NASA to see events that took place as long as around 13.5 billion years ago. This time period would be pretty close to when the Big Bang seemingly took place, at just 220 million years following it to be precise.

What the scientists will use it for

As mentioned above, one of the important things the NASA expects to achieve using the JWST is to see as back as the first galaxies of the universe. The other main objective will be to observe the very dark parts of the universe, where usually stars are born, but cannot be observed using the currently available tools due to their limitations.

And here is the video

Despite being so powerful, it’s surprising that the JWST wouldn’t really be much bigger to the Hubble Space Telescope. In fact, its diameter would be just around 6.5 meters, around thrice that of the latter.
