Space Observatories See Active Sun in UV Light and X-Rays

High-energy X-rays from NuSTAR are shown in blue; low-energy X-rays from Hinode are green; and extreme UV light from 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.

This Hubble image shows the cluster of galaxies MACS0416.1-2403. Bright yellow ‘elliptical’ galaxies can be seen, surrounded by numerous blue spiral and amorphous galaxies. Gravitational arcs can also be seen. This image forms the test data that the machine learning algorithm is applied to, having not previously seen the image. Image credit: NASA / ESA / J. Geach / A. Hocking.

A set of four rings around Circinus X-1 can be seen in this composite image where X-rays from Chandra are red, green, and blue corresponding to low, medium, and high-energy X-rays respectively, which have been combined with a view in visible light from the Digitized Sky Survey. The sharp edges are caused by the large size of the X-ray rings compared to the relatively small field-of-view of the Chandra detectors, providing only partial coverage.
