Transcribed Image Text:

1) The James Webb Space Telescope (JWST), launched in 2021, is a giant infrared space telescope. If you have not taken a look, the images it captures are stunning! Like the Hubble Space Telescope, the JWST orbits the Sun, 1.5 million kilometers away, at the second Lagrange point or L2. At Lagrange points, the gravitational pull of two large masses precisely equals the centripetal force required for a much smaller object to orbit. On the right is an image of our earth-moon system in orbit around the sun. L3 L4 L5 a) What is special about the so-called Lagrange points (L1, L2, L3, L4, and L5)? If you place a small object here, what do you expect to happen? b) Why do we launch the JWST strategically so that it orbits at L2, as opposed to any of the other Lagrange points? Consider what about this point gives us a better view from our telescope? L2 1) The James Webb Space Telescope (JWST), launched in 2021, is a giant infrared space telescope.
