Jupiter is shown in visible light for context underneath an artistic impression of the Jovian upper atmosphere’s infrared glow. The brightness of this upper atmosphere layer corresponds to temperatures, from hot to cold, in this order: white, yellow, bright red and lastly, dark red. The aurorae are the hottest regions and the image shows how heat may be carried by winds away from the aurora and cause planet-wide heating. Image credit: J.

Wilkins et al. observed bright flares of X-ray emissions, produced as gas falls into a supermassive black hole in I Zwicky 1; the flares echoed off of the gas falling into the black hole, and as the flares were subsiding, short flashes of X-rays were seen -- corresponding to the reflection of the flares from the far side of the disk, bent around the black hole by its strong gravitational field.

This Hubble image shows the galaxy cluster MACS J0138.0-2155, which is so massive that its gravity bent and magnified light streaming not only from an extremely distant background galaxy but also from a supernova event in this galaxy. The color image was made using observations from eight different filters spread across Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / A. Newman / M. Akhshik / K. Whitaker.

This Hubble image shows NGC 6380, a globular cluster some 35,500 light-years away in the constellation of Scorpius. The very bright star at the top of the image is HD 159073, which is only around 4,000 light-years from Earth. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Enceladus’ tiger stripes are known to be spewing ice from the moon’s icy interior into space, creating a cloud of fine ice particles over the moon’s south pole and creating Saturn’s mysterious E-ring. Evidence for this has come from NASA’s Cassini spacecraft that orbited Saturn from 2004 to 2017. Pictured here, a high resolution image of Enceladus is shown from a close flyby. Tiger stripes are visible in false-color blue. Image credit: NASA / ESA / JPL / SSI / Cassini Imaging Team.
