    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 …

    NASA InSight’s Power Level as of Oct. 22, 2022

    As of October 22, 2022, InSight's seismometer is collecting data again after being switched off to conserve energy after a recent dust storm. The lander was generating an average of 280 watt-hours of energy per Martian day, or sol. The tau, or level of dust cover in the atmosphere, was estimated at 1.45 (typical tau …

    Student of the Sea: Learning the Ropes Aboard NASA’s S-MODE Mission

    A science team of roughly 20 people stands on the pier in front of a research vessel.

    By Igor Uchôa, Ph.D. student at the University of Maryland in the Atmospheric and Oceanic Sciences Department // Aboard the Bold Horizon // NASA's S-MODE mission was designed to measure and understand the complex oceanic features classified as "submesoscale," i.e., features spanning up to 6.2 miles (10 kilometers) across. Such fine filaments and sharp density …

    NASA’s Geotail Mission Experiences an Anomaly

    Artistic representation of the Geotail spacecraft. The 3D image blue spacecraft is set against the dark back drop of space in the distance are small orbs representing planets and a bright white circle representing the Sun.

    NASA's Science Mission Directorate, Japan's Institute of Space and Astronautical Science (ISAS), and the Japan Aerospace Exploration Agency (JAXA) are determining how to move forward with the joint Geotail mission since discovering the spacecraft's last operational data recorder has failed. Originally, Geotail was equipped with two data recorders to collect the mission's scientific data. One …

    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 …
