Zeta Ophiuchi was once in close orbit with another star, before being ejected when this companion was destroyed in a supernova explosion; infrared data from Spitzer reveal a spectacular shock wave (red and green) that was formed by matter blowing away from the star’s surface and slamming into gas in its path; data from Chandra (blue) show a bubble of X-ray emission located around the star, produced by gas that has been heated by the shock wave to tens of millions of degrees.

This Hubble image shows three galaxies LEDA 58109, SDSS J162558.14+435746.4, and SDSS J162557.25+435743.5. The color image is composed of infrared, optical and ultraviolet observations from Hubble’s Advanced Camera for Surveys (ACS), the Dark Energy Camera (DECam) on the Victor M. Blanco 4-m Telescope, and the Sloan Digital Sky Survey (SDSS). Nine 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 / W. Keel.

This artist’s impression shows what the binary system VFTS 243 might look like if we were observing it up close. The system, which is located in the Tarantula Nebula in the Large Magellanic Cloud, is composed of a hot, blue star with 25 times the Sun’s mass and a black hole, which is at least nine times the mass of the Sun. The sizes of the two binary components are not to scale: in reality, the blue star is about 200,000 times larger than the black hole. Image credit: ESO / L. Calçada.

Two cameras aboard Webb captured these images of the Southern Ring Nebula: two stars, which are locked in a tight orbit, shape the local landscape; they are prominent in the image from Webb’s Near-Infrared Camera (NIRCam) on the left, while the image from Webb’s Mid-Infrared Instrument (MIRI) on the right shows for the first time that the second star is surrounded by dust; the brighter star is in an earlier stage of its stellar evolution and will probably eject its own planetary nebula in the future.

This landscape of ‘mountains’ and ‘valleys’ speckled with glittering stars is actually the edge of the Carina Nebula, a huge star-forming region some 7,500 light-years away in the constellation of Carina. Captured in infrared light by Webb, this image reveals for the first time previously invisible areas of star birth. Called the Cosmic Cliffs, Webb’s seemingly 3D picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within the Carina Nebula, and the tallest ‘peaks’ in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.
