This Hubble image shows the barred spiral galaxy NGC 685. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This image is a snapshot from a 16-minute time-lapse movie showing the formation and collapse of a complexly shaped plasma stream traveling at almost 100 km per seconds in front of a coronal loop system. This is likely the first time such a stream, which the scientists refer to as plasmoid, has been observed, leaving them wondering about the physical explanation of the observed dynamics. This image was taken by the Goode Solar Telescope at Big Bear Solar Observatory using the new coronal adaptive optics system Cona. The image shows the hydrogen-alpha light emitted by the solar plasma. The image is artificially colorized, yet based on the color of hydrogen-alpha light, and darker color is brighter light.

This artist’s impression shows a galactic merger in which the galaxy on the right hosts a quasar at its core; this quasar is powered by a supermassive black hole swallowing up material around it and emitting a powerful cone of radiation, piercing the other galaxy like a lance; as this radiation interacts with the galaxy on the left, it disrupts the clouds of gas and dust within, leaving behind only the smallest and densest regions; these regions are likely rendered incapable of star formation after the process.
