It’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 one million miles away from Earth on Dec. 24.
What will it help us discover? And what’s at stake?
From National Geographic’s Nadia Drake:
We meet one of the head scientists behind the telescope — plus, three astronomers whose future work hinges on the discoveries of the mission.
