For the first time, NASA?s James Webb Space Telescope and Hubble Space Telescope have taken simultaneous observations of the same target. These images, Hubble on left and Webb on the right, show observations of the Didymos-Dimorphos system several hours after NASA?s Double Asteroid Redirection Test (DART) intentionally impacted the moonlet asteroid. It was the world?s first test of the kinetic impact technique using a spacecraft to deflect an asteroid by modifying its orbit. Both Webb and Hubble observed the asteroid before and after the collision took place. Scientists will use the combined observations from Hubble and Webb to gain knowledge about the nature of the surface of Dimorphos, how much material was ejected by the collision, how fast it was ejected, and the distribution of particle sizes in the expanding dust cloud. In the coming months, scientists will also use Webb?s Mid-Infrared Instrument (MIRI) and Near-Infrared Spectrograph (NIRSpec) to observe ejecta from Dimorphos further. Spectroscopic data will provide researchers with insight into the asteroid?s composition. Hubble will monitor Dimorphos ten more times over the next three weeks to monitor how the ejecta cloud expands and fades over time. Hubble observations were conducted in one filter, WFC3/UVIS F350LP (assigned the color blue), while Webb observed at F070W (0.7 microns, assigned the color red).

Webb?s Near-Infrared Camera (NIRCam) image of Neptune, taken on July 12, 2022, brings the planet?s rings into full focus for the first time in more than three decades. The most prominent features of Neptune?s atmosphere in this image are a series of bright patches in the planet?s southern hemisphere that represent high-altitude methane-ice clouds. More subtly, a thin line of brightness circling the planet?s equator could be a visual signature of global atmospheric circulation that powers Neptune?s winds and storms. Additionally, for the first time, Webb has teased out a continuous band of high-latitude clouds surrounding a previously-known vortex at Neptune?s southern pole.

Top right: NIRCam image showing 2.1-micron (F212 filter) reflected sunlight, revealing surface features such as craters and dust layers. Bottom right: Simultaneous NIRCam image showing ~4.3-micron (F430M filter) emitted light that reveals temperature differences with latitude and time of day, as well as darkening of the Hellas Basin caused by atmospheric effects. The bright yellow area is just at the saturation limit of the detector
