Questão de Inglês — Verbos (Verbs) — CESPE / CEBRASPE 2025

About 39% of the sky is potentially visible to Webb at any given time. Over the course of 6 months, Webb has a view of almost the entire sky (i.e., the ability to point in almost every direction). Two small regions of the sky known as CVZs (Continuous Viewing Zones) can be observed at any time.

Because Webb must face away from objects that are warm enough and close enough to interfere with its ability to observe faint infrared light, it cannot observe the Sun, Mercury, Venus, Earth, or the Moon. (It can observe the parts of the Solar System that are beyond its orbit, including Mars, the asteroid belt, the outer planets, and the Kuiper Belt.)
