Here's Why You Should Be Excited About The James Webb Space Telescope

Peter Cullen, voice of Optimus Prime, recently lent his legendary voice to a slick animated introduction to the successor of the ridiculously prolific Hubble Telescope, NASA's James Webb Space Telescope. But Cullen's velvety voice is far from the only reason to be excited about JWST.

If you're not excited about JWST, you might be dead inside. That, or you just don't know enough about it to be excited. JWST is so powerful that astrophysicists aren't even sure what they'll be able to use it for once it's out in space. Sure, they have plans for it – but, like Hubble, it's likely that Webb's biggest scientific milestones will be discoveries we can't even begin to anticipate today. Just listen to what Michael Shara, Curator in the Department of Astrophysics at the American Museum of Natural History, had to say about it when we spoke with him about the future of space exploration:

[The James Webb Space Telescope] has, in many ways, 100 times the capabilities that the Hubble Space Telescope does. We're actually going to be able to see the first stars forming, the first galaxies forming after the Big Bang. We're also going to be able to — we think — directly image planets orbiting other stars.

There isn't a field in all of astrophysics that will not benefit tremendously. Just as Hubble was… not just a leap, but an enormous leap forward for all of astrophysics, including the discovery of Dark Energy (70% of… the energy of the Universe was unknown before Hubble), I find it almost impossible to believe that we won't make the same kinds of discoveries with the James Webb Telescope.

Once [we] started seeing things with Hubble that [we'd] never seen before, [we] pushed it harder and harder to do new things. The same will happen with the James Webb Space Telescope. We will discover new things that we have no way of knowing about today, no way of guessing [because] our intuition isn't able to take us there. And those will be the great discoveries that actually show up in the coming 20 years, in the coming 30 years. It is really, in many ways, the golden age of astronomy — it's the very best time ever to be an astronomer.


If that doesn't send chills up your spine, I don't know what will.

My biggest fear is something going wrong. Leak in the coolant supply like what happen with WIRE or premature failure of reaction wheels like we've seen in Hubble but now with absolute no capability to repair them, since the JWST will be at the Earth-Sun L2. Compared to Hubble's life span, JWST will have a very shortened life span in comparison even if everything works at 100%.

At $9 billion for a 5 year mission is a bit steep considering the US doesn't have the capability to even launch it, it's going up on an Ariane 5.
