Using data from the NASA/ESA Hubble Space Telescope, NASA’s Spitzer Space Telescope, and Magellan II Telescope at Las Campanas Observator in Chile, astronomers have found that the atmosphere of the inflated hot Jupiter WASP-79b is almost transparent to blue light, leaving it with a yellow-tinged sky.

PKS 2014-55 is classified as ‘X-shaped’ because of its appearance in previous relatively blurry images. The detail provided in this radio image obtained with the MeerKAT telescope indicates that its shape is best described as a double boomerang. Two powerful jets of radio waves, indicated in blue color, each extend 2.5 million light-years into space. Eventually, they are ‘turned back’ by the pressure of tenuous intergalactic gas. As they flow back towards the central galaxy, they are deflected by its relatively high gas pressure into the shorter, horizontal, arms of the boomerang. The background image shows visible light from myriad galaxies in the distant Universe. Image credit: NRAO / AUI / NSF / SARAO / DES.

This Hubble image shows the barred spiral galaxy NGC 3583. 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.

Flaring, active regions of the Sun are highlighted in this image combining observations from several telescopes. High-energy X-rays from NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) are shown in blue; low-energy X-rays from Japan’s Hinode spacecraft are green; and extreme ultraviolet light from NASA’s Solar Dynamics Observatory (SDO) is yellow and red. All three telescopes captured their solar images around the same time on April 29, 2015. Image credit: NASA / JPL-Caltech / GSFC / JAXA.
