The James Webb Space Telescope (JWST), positioned nearly a million miles from Earth at the Second Lagrange Point (L2), has revolutionized observational astronomy since its deployment. Equipped with a gold-coated primary mirror measuring 6.5 meters across and ultra-sensitive infrared detectors, JWST can peer through dense cosmic dust clouds that previously obscured the view of optical telescopes like Hubble. Infrared sensitivity is crucial because light emitted by the earliest stars and galaxies billions of years ago has experienced cosmological redshift, stretching its wavelengths toward the infrared spectrum as the universe expanded. Initial observations have revealed massive, highly structured galaxies that formed just a few hundred million years after the Big Bang, challenging preexisting models of stellar evolution which posited that galaxy assembly required much longer timescales. As astronomers continue to analyze high-resolution spectroscopic data, the telescope promises to yield unprecedented insights into the origins of planetary systems and the atmospheric compositions of distant exoplanets.
What is the primary purpose of the passage?
A)To explain how the James Webb Space Telescope is transforming our understanding of the early universe
B)To compare the maintenance costs of Hubble and newer space observatories
C)To prove that older cosmological theories were entirely fabricated without evidence
D)To describe the chemical composition of solar flares in the Milky Way
E)To criticize the delay in launching deep-space satellites

Glaciological radar surveys indicate that sub-surface intrusions of warm Circumpolar Deep Water are eroding the grounding zones of marine-terminating glaciers. As pinning points weaken across retrograde continental shelves, accelerated calving could significantly contribute to global sea-level rise.
