How Webb is Defining Possible
NASA’s Webb Telescope is using its superb angular resolution and near-infrared instruments to discover and study planetary systems similar to our own, analyzing the molecular composition of extrasolar planets’ atmospheres and directly imaging Jupiter-size planets orbiting nearby stars.
Webb is making observations once thought to be impossible; multiple new technologies had to be invented simply to build it. The groundbreaking mirror and powerful instruments are being used to discover and study distant planetary systems.
Webb is also looking deep into the past, to a time when the earliest stars and galaxies were born. By extending our knowledge of the cosmos, the Webb telescope will help us answer the compelling questions, “How did we get here?” and “Are we alone?”
