    Webb Offers Never-Before-Seen Details of Early Universe

    A James Webb Space Telescope image of galaxy cluster MACS0647 and the very distant galaxy MACS0647-JD. At left, the cluster appears as a sea of galaxies on a black background. The image is punctuated by a few foreground stars with prominent diffraction spikes. Three small boxes outlined in white mark the locations of the three images of galaxy MACS0647-JD. They are numbered 1, 2, and 3. Enlarged images of these boxes appear in a column down the right side of the screen. They are labeled JD 1, JD 2, and JD 3. The three images of MACS0647-JD from Webb show two, distinct features that are differently colored, with the larger area appearing redder and the smaller one appearing bluer.

    Editor's Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. NASA's James Webb Space Telescope was specially designed to detect the faint infrared light from very distant galaxies and give astronomers a glimpse at the early universe. The nature of galaxies during this early period …

    Webb Reveals Shells of Dust Surrounding Brilliant Binary Star System

    A bright white point of light is surrounded by ten to fifteen regularly spaced, hazy rings at its bottom, right, and upper right. The central point, where the stars are located, has a rough hexagon shape. The innermost ring is highlighted blueish white and is much brighter to the right. The outer rings fade from view to the upper left, with only a few close rings visible there. The central light seems to highlight the misshapen rings like a spotlight, with rays coming out diagonally from the upper left to lower right. One ray illuminates even more rings as it travels to the upper right.

    The latest image from NASA‘s James Webb Space Telescope is a new perspective on the binary star Wolf-Rayet 140, revealing details and structure in a new light. Astronomer Ryan Lau of NSF's NOIRLab, principal investigator of the Webb Early Release Science program that observed the star, shares his thoughts on the observations. "On the night …

    Webb, Hubble Team Up to Trace Interstellar Dust Within a Galactic Pair

    The majority of the image shows the black background of space. Two large, very bright galaxies dominate the center of the image. The elliptical galaxy at left is extremely bright at its circular core, with dimmer white light extending to its transparent circular edges. At right is a bright spiral galaxy. It also has a bright white core, but has red and light purple spiral arms that start at the center and turn clockwise going outward. They end in faint red and appear to overlap the elliptical galaxy at left. Throughout the scene are a range of distant galaxies, the majority of which are very tiny and red, appearing as splotches.

    Editor's Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. Here, Webb interdisciplinary scientist Rogier Windhorst and his team discuss their observations. "We got more than we bargained for by combining data from NASA's James Webb Space Telescope and NASA's Hubble Space Telescope! Webb's new …
