In new research, astronomers using the NASA/ESA Hubble Space Telescope searched for signs of interactions between the magnetic environment and the surfaces of Uranus and its four largest moons: Ariel, Umbriel, Titania, and Oberon. They predicted that, based on interactions with Uranus’ magnetosphere, the ‘leading’ sides of these tidally locked moons would be brighter than the ‘trailing’ sides, always facing away. This would be due to radiation...

This Hubble image shows IC 758, a barred spiral galaxy some 60 million light-years away in the constellation of Ursa Major. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum. Two 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 / C. Kilpatrick.

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.
