Engineers and technicians assemble the James Webb Space Telescope at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Alex Wong/Getty ImagesIt's been more than 20 years since scientists set their sights on creating a successor for the Hubble telescope.
Now, the James Webb Space Telescope — a $10 billion infrared instrument — is set to launch and begin its million-mile journey away from Earth on Dec. 24.
From National Geographic's Nadia Drake:
In the case of JWST, the vibrant landscapes surrounding the complex serve as a reminder of the space telescope's mission: to help scientists understand how we got here—how, from the tangle of molecules, stars, galaxies, black holes, and planets that populate the universe, the ingredients necessary for life emerged and combined to make this place called Earth. Are the conditions that favored this thriving, noisy biosphere common among the millions, or perhaps billions, of rocky planets populating the galaxy?
What will it help us discover? And what's at stake?
John Mather, Nikole Lewis, Priyamvada Natarajan, and Caitlin Casey join us for the conversation.
