It's springtime and the deployed primary mirror of NASA's James Webb Space Telescope looks like a spring flower in full bloom. In this photo, NASA technicians lifted the telescope using a crane and moved it inside a clean room at NASA?s Goddard Space Flight Center in Greenbelt, Maryland. Once launched into space, the Webb telescope?s 18-segmented gold mirror is specially designed to capture infrared light from the first galaxies that formed in the early universe, and will help the telescope peer inside dust clouds where stars and planetary systems are forming today. The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

Faint distant galaxies spotted by JWST may be closer than they appear

Because of a calibration update for one of the James Webb Space Telescope鈥檚 main cameras, research using the first few weeks of data from the observatory may be flawed

W0MN5G This undated NASA/ESA Hubble Space Telescope image shows the galaxy IC 335 in front of a backdrop of distant galaxies. IC 335 is part of a galaxy group containing three other galaxies, and located in the Fornax Galaxy Cluster 60 million light-years away, December 30, 2014. As seen in this image, the disc of IC 335 appears edge-on from the vantage point of Earth. UPI/NASA

This side-by-side comparison shows observations of the Southern Ring Nebula in near-infrared light, at left, and mid-infrared light, at right, from NASA???s Webb Telescope. This scene was created by a white dwarf star ??? the remains of a star like our Sun after it shed its outer layers and stopped burning fuel though nuclear fusion. Those outer layers now form the ejected shells all along this view. In the Near-Infrared Camera (NIRCam) image, the white dwarf appears to the lower left of the bright, central star, partially hidden by a diffraction spike. The same star appears ??? but brighter, larger, and redder ??? in the Mid-Infrared Instrument (MIRI) image. This white dwarf star is cloaked in thick layers of dust, which make it appear larger. The brighter star in both images hasn???t yet shed its layers. It closely orbits the dimmer white dwarf, helping to distribute what it???s ejected. Over thousands of years and before it became a white dwarf, the star periodically ejected mass ??? the visible shells of material. As if on repeat, it contracted, heated up ??? and then, unable to push out more material, pulsated. Stellar material was sent in all directions ??? like a rotating sprinkler ??? and provided the ingredients for this asymmetrical landscape. Today, the white dwarf is heating up the gas in the inner regions ??? which appear blue at left and red at right. Both stars are lighting up the outer regions, shown in orange and blue, respectively. The images look very different because NIRCam and MIRI collect different wavelengths of light. NIRCam observes near-infrared light, which is closer to the visible wavelengths our eyes detect. MIRI goes farther into the infrared, picking up mid-infrared wavelengths. The second star more clearly appears in the MIRI image, because this instrument can see the gleaming dust around it, bringing it more clearly into view. The stars ??? and their layers of light ??? steal more attention in the NIRCam image, while dust pl
