ALT Three people in head-to-toe white clean room jumpsuits are pushing a large white metal box crate on wheels into a clean room at NASA Goddard. There is a person, off to the left, also in a white jumpsuit, supervising the move. The back wall is covered in hundreds of small square filters that are a pale pink color.
ALT A mini grand piano sized structure covered in silver foil-like material on the bottom and a black tarp on the top is being lifted up off its white metal base. There are people in head to toe white clean room jumpsuits surrounding the structure and holding on to rope to guide it.
ALT Two people in head-to-toe white clean room jumpsuits stand on either side of the Coronagraph Instrument pulling off a black tarp-like material off the top of it. The cover unveils a black metal frame with wires and pipes coming out of it. The bottom of the structure is covered in a silver foil-like material.
ALT A close-up shot of a metal box with five glowing colored circles embedded in the side. There are wires covered in a gold-colored material in front of the box.
ALT This image shows two views of the dusty debris disk around the red dwarf star AU Mic. The top panel is the disk at 3.56 microns. The disk appears as a fuzzy, blue, horizontal line broken in the middle by a black region outlined by a white, dashed circle. In the center of that region is a white, graphical star, which represents AU Mic. The actual star is blocked out in this image by Webb’s NIRCam coronagraph. The bottom panel is the second view of the disk, at 4.44 microns. The disk appears as a fuzzy, red, horizontal line broken in the middle by a black region outlined by a white, dashed circle. As in the top panel, in the center of that region is a cartoonish star representing AU Mic. The actual star is blocked out by the NIRCam’s coronagraph.
ALT Graphic titled Hot Gas-Giant Exoplanet WASP-43 b: Phase Curve 1 ¼ Orbits; MIRI Low-Resolution Spectroscopy. y-axis: Brightness of Planet + Star (5 to 12 micron emitted light), ranging from dimmer at bottom to brighter at top. x-axis: Elapsed Time (Hours) ranging from 0 to 24 in increments of 4. Thousands of orange data points form a thick, clear pattern, with no outliers and very little scatter. Curve forms a subtle sine wave with crests from 2-4 hours and 20-24 hours, and trough in the middle from 10-14 hours. Curve interrupted by 3 prominent U-shaped valleys: 2 shallow valleys at the wave crests at 2 hours and 22 hours, and a very deep valley in the middle of the trough at 12 hours. The base of the shallow valleys at 2 and 22 hours are labeled “starlight only,” with tops of valley walls on either side labeled “dayside + star.” Center of deep valley at 12 hours is labeled “nightside + partially-blocked star,” with tops of valley walls on either side labeled “nightside + star.”
ALT Illustration of an exoplanet on a black background. The planet is large, in the foreground on the left. The planet is various shades of blue, with wisps of white scattered throughout.
