    Second-most Distant Galaxy discovered using James Webb Space Telescope

    The second- and fourth-most distant galaxies ever seen (UNCOVER z-13 and UNCOVER z-12) have been confirmed using the James Webb Space Telescope’s Near-Infrared Camera (NIRCam). The galaxies are located in Pandora’s Cluster (Abell 2744), shown here as near-infrared wavelengths of light that have been translated to visible-light colors. The scale of the main cluster image is labelled in arcseconds, which is a measure of angular distance in the sky. The circles on the black-and-white images, showing the galaxies in the NIRCam-F277W filter band onboard JWST, indicate an aperture size of 0.32 arcsec. Credit: Cluster image: NASA, UNCOVER (Bezanson et al., DIO: 10.48550/arXiv.2212.04026).

    Webb reveals Intricate Details in the Remains of a Dying Star

    Side-by-side images of the Ring Nebula where the nebula appears as a distorted doughnut. On the right, the nebula’s inner cavity hosts shades of blue and green, while the detailed ring transitions through shades of orange in the inner regions and pink in the outer region. On the left, the nebula’s inner cavity hosts shades of red and orange, while the detailed ring transitions through shades of yellow in the inner regions and blue/purple in the outer region. The ring’s inner region has distinct filament elements.
    New images from NASA’s James Webb Space Telescope of the well-known Ring Nebula provide unprecedented spatial resolution and spectral sensitivity. In the NIRCam (Near-Infrared Camera) image on the left, the intricate details of the filament structure of the inner ring are particularly visible in this dataset. On the right, the MIRI (Mid-InfraRed Instrument) image reveals particular details in the concentric features in the outer regions of the nebulae’s ring.

    XRISM Spacecraft will Open New Window on the Xray Cosmos

    August 17, 2023, Categories  Astronomy/Space

    Scientists studied NGC 7319, part of the visual grouping of galaxies called Stephan’s Quintet, using the Medium-Resolution Spectrometer (MRS) in the Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope. The galaxy contains a supermassive black hole that is actively accreting material. The spectrometer features integral field units (IFUs) – each containing a camera and spectrograph. IFUs provided the Webb team with a collection of images of the galactic core’s spectral features, shown here. Blue-colored regions indicate movement toward the viewer and orange-colored regions represent movement away from the viewer. Powerful radiation and winds from the black hole ionize hot spots of super-heated gas, creating the argon and neon lines...

    Astronomers Confirm Maisie’s Galaxy is Among Earliest Ever Observed

    Astronomers confirm Maisie's galaxy is among earliest ever observed
    Spectroscopic observations reveal that Maisie’s galaxy, named after Steven Finkelstein’s daughter, was detected 390 million years after the Big Bang. That makes it one of the four earliest confirmed galaxies ever observed. Credit: NASA/STScI/CEERS/TACC/ University of Texas at Austin/S. Finkelstein/M. Bagley

    Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings are published in the journal Nature.

    Follow-up observations since first detection of Maisie’s galaxy have revealed that it is from 390 million years after the Big Bang...
