![]() ![]() Webb fills in the gaps with infrared instruments, whose data can be combined with previous visible and ultraviolet spectrum imaging, providing the first complete images of planets and galaxies. On July 12, the James Webb Space Telescope’s near-infrared and mid-infrared instruments issued their first clear glimpses of thousands of galaxies in a deep-field view that took advantage of gravitational lensing, when the powerful gravitational field of a huge group of galaxies bends the light rays from more distant galaxies, pulling them into our view. This means that light detected by Webb from the most distant galaxies in the cosmos provides insight into the universe as it was billions of years ago.What’s the oldest galaxy humanity has ever seen? Our vision now extends to astonishingly cosmic distances. Telescopes like Webb can essentially peer back into the universe's history because it takes time for light to travel through space. ![]() Space Telescope Science Institute / NASA, ESA, CSA, and STScI The so-called spectrum revealed water vapor in the planet's atmosphere. The James Webb Space Telescope captured different wavelengths of light from an exoplanet known as WASP-96b, located more than 1,000 light-years away from Earth. As such, the telescope is expected to provide first-of-its-kind infrared views of the universe, and capture some never-before-seen cosmic objects. The spacecraft, which is the size of a tennis court, is equipped with infrared "eyes" that can pierce through dust and gas that might otherwise make some stars, galaxies and celestial targets undetectable. ![]() After spending more than six months testing and configuring the spacecraft's various instruments, NASA officials said the observatory's science operations are now ready to begin in earnest. The Webb telescope, a collaboration among NASA, the European Space Agency and the Canadian Space Agency, launched into space Dec. ![]()
