NASA launches James Webb Space Telescope into space

NASA's Webb Telescope Launches to See First Galaxies, Distant Worlds

Webb’s sensitivity to infrared light – including mid-infrared wavelengths that can only be captured from space – will allow the team to observe these objects, whose light has traveled for 13 billion years and has had its wavelengths stretched from ultraviolet and visible light into infrared light.
Webb has unmatched sensitivity and spatial resolution, which will reveal complex structures in these distant objects. The team plans to observe and analyze the data on three scales: closely examining the quasars themselves, studying the stars in the surrounding host galaxies after removing the quasars’ light, and classifying the galaxies that lie nearby.
“These quasars are very special objects,” explained Bañados.“That is why we want to provide the best characterization possible of each with Webb.”
