With NASA's newest space observatory exactly on schedule in its commissioning phase, the science team outlined their plan to make the most of this $10 billion opportunity.

The James Webb Space Telescope arrived days ago at its destination at the Earth-sun Lagrange Point 2 (L2), which is about 930,000 miles (1.5 million kilometers) away from our planet. 

The principal investigators of the Webb science team outlined their plan in a town hall Friday (Jan. 28) hosted online by the Space Telescope Science Institute (STScI) in Baltimore.

The James Webb Space Telescope is setting its eyes towards the Big Dipper.

Although the spacecraft is still months away from beginning its official scientific observations, one particularly bright star named HD 84406 will soon be the object of JWST's attention.

"Star light, star bright … the first star Webb will see is HD 84406, a sun-like star about 260 light years away," NASA officials tweeted on Friday (Jan. 28) via JWST's official Twitter account.
