ALT This panchromatic view of galaxy cluster MACS0416 was created by combining infrared observations from NASA’s James Webb Space Telescope with visible-light data from NASA’s Hubble Space Telescope. The resulting wavelength coverage, from 0.4 to 5 microns, reveals a vivid landscape of galaxies whose colors give clues to galaxy distances: The bluest galaxies are relatively nearby and often show intense star formation, as best detected by Hubble, while the redder galaxies tend to be more distant, or else contain copious amount of dust, as detected by Webb. The image reveals a wealth of details that are only possible to capture by combining the power of both space telescopes. In this image, blue represents data at wavelengths of 0.435 and 0.606 microns (Hubble filters F435W and F606W); cyan is 0.814, 0.9, and 1.05 microns (Hubble filters F814W, and F105W and Webb filter F090W); green is 1.15, 1.25, 1.4, 1.5, and 1.6 microns (Hubble filters F125W, F140W, and F160W, and Webb filters
ALT A sketch of the Nautilus mission concept posters at AGU23. It shows a spacecraft, in gold (center), flying by Neptune’s large moon, Triton (top right). A deep blue Neptune looms in the background (top left). The sketch includes some text describing the instrument suite (Vis/IR camera, plasma/mag suite, UV spectrometer), mission design (long cruise to Neptune orbit), and power system (2 RTGs). The bottom of the sketch shows a wedge of Triton’s interior lying on its side, with the surface on the left and core on the right. The wedge is broken down into a few different hypotheses, including: whether the plumes are shallowly sourced or come from the ocean; whether there is or is not an ocean; and whether Triton has a metallic core.
ALT Dramatic plumes (cloudy, white areas), both large and small, spray water ice out from many locations along the famed "tiger stripes" near the south pole of Saturn's moon Enceladus. The tiger stripes are fissures that spray icy particles, water vapor and organic compounds. More than 30 individual jets of different sizes can be seen in this image and more than 20 of them had not been identified before. This mosaic was created from two high-resolution images that were captured by the narrow-angle camera when NASA’s Cassini spacecraft flew past Enceladus and through the jets on Nov. 21, 2009.
ALT Illustration showing the surface of Europa, one of Jupiter's icy moons. Europa takes up the bottom portion of the image, with blue-black ridges and canyons stretching off into the horizon. Jupiter looms in the background with its Great Red Spot visible. The Europa Clipper spacecraft transits above the surface of Europa. White text reads "Final Boarding Call!

ALT Circular metallic instrument of concentric circles on aluminum foil, the TAGSAM head from the OSIRIS-REx spacecraft. The outer ring contains many small circles containing small particles of black dust. The inner circle contains small rocks.
