This Hubble image reveals a detailed view of the central part of the grand design spiral galaxy NGC 5364. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This image of the Tarantula Nebula combines data from multiple Spitzer observations, most recently in February and September 2019. The image shows the nebula in two wavelengths of infrared light, each represented by a different color. The red color at the heart of the nebula shows the presence of particularly hot gas emitting infrared light at a wavelength of 4.5 micrometers. The blue regions are dust composed of molecules called polycyclic aromatic hydrocarbons. Regions emitting both wavelengths appear white. Image credit: NASA / JPL-Caltech.

$Cassini captured this image of Enceladus as it neared the moon for its closest-ever dive past the moon’s active south polar region. The image was taken in visible light with the spacecraft’s narrow-angle camera on October 28, 2015. The image shows heavily cratered northern latitudes at top, transitioning to fractured, wrinkled terrain in the middle and southern latitudes. The wavy boundary of the moon's active south polar region is visible at bottom, where it disappears into wintry darkness. This view looks towards the Saturn-facing side of Enceladus. The image was taken at a distance of approximately 60,000 miles (96,000 km) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 45 degrees.

This Hubble image shows NGC 1022, a face-on barred spiral galaxy located in the constellation of Cetus, approximately 62 million light-years away. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / A. Seth.
