This ALMA image shows the outcome of a stellar fight: a complex and stunning gas environment surrounding the binary system HD 101584. The colors represent speed, going from blue (gas moving the fastest towards us) to red (gas moving the fastest away from us). Jets, almost along the line of sight, propel the material in blue and red. The stars in the binary are located at the single bright dot at the center of the ring-like structure shown in green, which is moving with the same velocity as the system as a whole along the line of sight. Astronomers believe this ring has its origin in the material ejected as the lower mass star in the binary spiraled towards its red-giant partner.

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.
