There are three images. The top right is Cassiopeia A. This image of Cassiopeia A resembles a disk of electric light with red clouds, glowing white streaks, red and orange flames, and an area near the center of the remnant resembling a somewhat circular region of green lightning. X-rays from Chandra are blue and reveal hot gas, mostly from supernova debris from the destroyed star, and include elements like silicon and iron. X-rays are also present as thin arcs in the outer regions of the remnant. Infrared data from Webb is red, green, and blue. Webb highlights infrared emission from dust that is warmed up because it is embedded in the hot gas seen by Chandra, and from much cooler supernova debris. Hubble data shows a multitude of stars that permeate the field of view. The image on the bottom is 30 Doradus. This release features a composite image of 30 Doradus, otherwise known as the Tarantula Nebula, a region of active star formation in a neighboring galaxy. In the image, royal blue and purple gas clouds interact with red and orange gas clouds. Specks of light and large gleaming stars peek through the colourful clouds. The patches of royal blue and purple gas clouds represent X-ray data collected by the Chandra Observatory. The brightest and most prominent blue cloud appears at the center of the image, roughly shaped like an upward pointing triangle. Darker X-ray clouds can be found near the right and left edges of the image. The red and orange gas clouds represent infrared data from the James Webb Space Telescope. These patches resemble clouds of roiling fire. The brightest and most prominent infrared cloud appears at our upper left, roughly shaped like a downward pointing triangle. Wispy white clouds outline the upward pointing bright blue triangle in the center of the image. Inside this frame is a brilliant gleaming star with six long, thin, diffraction spikes. Beside it is a cluster of smaller bright specks showing young stars in the nebula. The final image is NGC 6872. In this composite image, a large spiral galaxy has some of its superheated gas stolen by a smaller, nearby neighbor. Centered in the frame, NGC 6872 is a large spiral galaxy with two elongated arms that stretch toward our upper right and lower left. Near the white dot at the heart of the galaxy, a cloud of neon purple tints the arms, which appear steel blue at the tips. The purple represents hot gas detected by Chandra. Just to the upper left of NGC 6872 is a second spiral galaxy. Its spiraling arms are much smaller, but the bright white dot at its core is quite large, suggesting a supermassive black hole. Some of the steel blue matter and gas from NGC 6872’s lower arm appears to be floating toward the smaller galaxy, likely pulled toward the supermassive black hole.
