![]() ![]() Webb's first observations tell the story of the hidden universe through every phase of cosmic history – from neighboring exoplanets to the most distant observable galaxies in the early universe, and everything in between. Since these instruments and the others onboard operate to detect different wavelengths of light, the images can be stacked or compared to learn more about the composition or structure of their targets. NIRCam and MIRI played a role in creating several of the images released. George Rieke, Marcia's husband and also a Regents Professor of Astronomy at UArizona's Steward Observatory, serves as science team lead for the Mid-Infrared Instrument, or MIRI, which will observe the universe at longer wavelengths. These include the Near Infrared Camera, or NIRCam, which serves as the telescope's short wavelength imager and is led by principal investigator and UArizona Regents Professor of Astronomy Marcia Rieke. The release of Webb's first images and spectra kicks off the beginning of Webb's science operations, in which astronomers around the world will have their chance to observe anything from objects in our solar system to the early universe, using Webb's four instruments. This planetary nebula, about 2,500 light-years away and cataloged as NGC 3132, is known informally as the Southern Ring Nebula. The dimmer star at the center of this scene has been sending out rings of gas and dust for thousands of years in all directions, and NASA's Webb Telescope has revealed for the first time that this star is cloaked in dust. The images hint at the beginning of years of space science, which will in part be made possible by the 21 University of Arizona researchers who have played a role in developing and managing the instruments onboard. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.Īfter decades of development, a nail-biting launch and months of space travel and commissioning, NASA has released the first scientific images and spectroscopic data captured by the James Webb Space Telescope. Called the Cosmic Cliffs, it is the edge of the giant, gaseous cavity within NGC 3324. ![]() Captured in infrared light by NASA's Webb Telescope, this image reveals for the first time previously invisible areas of star birth. This landscape of what looks like mountains and valleys speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. ![]()
