Science discoveries made by @NASAWebb are expected to revolutionize our understanding of the cosmos and our origins within the universe! Dive into what Webb could reveal about the cosmos: Credit: ESO/M. Kornmesser. #AAS238 (1/9)
Mission goals for Webb include: Search for the first galaxies that formed in early universe; study the evolution of galaxies; observe star formation; and measure physical and chemical properties and investigate the potential for life in planetary systems. #AAS238 (2/9)
Webb is equipped with specialized instruments that detect infrared wavelengths, the light just beyond the visible spectrum. Infrared radiation can penetrate dense molecular clouds, whose dust blocks most of the light detectable by Hubble. Credit: NASA/JPL-Caltech #AAS238 (3/9)
Webb will aim to help us piece together what may have happened when the universe began expanding 13.8 billion years ago. It is the first observatory that will be capable of observing the very earliest galaxies, and perhaps even some of the first exploding stars. #AAS238 (4/9)
Webb is designed to help us understand the diversity of galaxy composition and structure over space and time; how galaxies form, interact, and change; and how supermassive black holes and their host galaxies influence each other. Credit: NASA/JPL-Caltech. #AAS238 (5/9)
Webb’s infrared wavelengths can look into dusty stellar nurseries to study very young stars and how those dusty environments contribute to the formation, evolution, and diversity of stars and planetary systems: #AAS238 (6/9)
One of Webb’s most anticipated contributions will be the study of exoplanets—planets orbiting distant stars. It will determine which elements are there and what they indicate about the world, including its potential to support life. Credit: NASA/ESA/STScI #AAS238 (7/9)
Astronomers are eager to use Webb’s instruments to look the objects in our own solar system. Understanding the weather and atmospheres of planetary bodies could potentially unlock clues to the origins of Earth and life as we know it. Credit: NASA. #AAS238 (8/9)
The Space Telescope Science Institute (@stsci) offers a variety of experts working directly with the telescope and the mission who are prepared to communicate in an understandable, public-friendly manner. Connect with our news team: #AAS238 (9/9)

Research telescopes include scientific instruments that record light precisely. The extreme sensitivity and precision of @NASAWebb’s four instruments support its unprecedented scientific power: Credit: NASA. #AAS238 (1/7)
Each of Webb’s four instruments is like a Swiss army knife of specialized components, with multiple ways of observing. All four can be used for investigations of the wide variety of objects that make up the universe, including planets, stars, nebulae, and galaxies. #AAS238 (2/7)
Webb’s instruments are housed in the Integrated Science Instrument Module (ISIM), which is situated behind the primary mirror on the cold side of the telescope where it is protected by the sunshield. Credit: NASA and STScI. #AAS238 (3/7)

The bigger the telescope, the better its vision. @NASAWebb is the largest telescope NASA has ever sent into space. Webb is designed to be as light as possible, but still measure large enough to achieve its scientific goals: Credit: NASA. #AAS238 (1/10) Image
Webb’s key components include an enormous primary mirror to collect infrared light, a supersized sunshield to keep the telescope cold, and four scientific instruments to conduct its ambitious science operations. Credit: NASA. #AAS238 (2/10) Image
Webb’s primary mirror towers more than two stories high. For the telescope to fit in the launch vehicle, an Ariane 5 rocket, it must fold origami-style to about a quarter of its full size, then unfold on its way to its orbit location. #AAS238 (3/10)
