An artist's rendering of what's called an active galactic nucleus at the center of NGC 4151. The galaxy's black hole sits at the center, immediately surrounded by an accretion disk shown in blue.

Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered by Cosmicflows-4 data. The streamlines within a given basin converge onto the region of high concentration of galaxies.

Monopoles of orbital angular momentum (OAM) are a tantalising prospect for orbitronics because OAM is uniform in all directions. This would mean that information flows could be generated in any direction. (Image Paul Scherrer Institute / Monika Bletry)

This is an artist's concept looking down into the core of the giant elliptical galaxy M87. A supermassive black hole ejects a 3,000-light-year-long jet of plasma, traveling at nearly the speed of light. In the foreground, to the right is a binary star system. The system is far from the black hole, but in the vicinity of the jet. In the system an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. As the hydrogen accumulates on the surface of the dwarf, it reaches a tipping point where it explodes like a hydrogen bomb. Novae frequently pop-off throughout the giant galaxy of 1 trillion stars, but those near the jet seem to explode more frequently. So far, it's anybody's guess why black hole jets enhance the rate of nova eruptions.

The authors measured the relative scale and spacing of the whirling brush strokes in van Gogh’s “The Starry Night,” along with variances in luminance of the paint, to see if the laws that apply in the physics of real skies apply in the artist’s depiction. The results suggest van Gogh had an innate understanding of atmospheric dynamics. He captured multiple dimensions of atmospheric physics with surprising accuracy.
